    “COUNTER MEASUREMENT EQUIPMENT FOR REPLACING BATTERY WITHOUT CERTIFICATION FOR ELECTRIC VEHICLE”
    TECHNICAL FIELD
    The present invention refers to a technological countermeasure that is carried out in a case where starting from the replacement of an electric vehicle battery that uses at least one electric motor as part of a power source, for example, an electric car using only the electric motor with a power source; a hybrid vehicle that moves using power supplied from a machine and an electric motor, etc., the replaced battery is a non-certified battery for the electric vehicle.
    TECHNICAL FUNDAMENTALS
    An electric vehicle such as an electric car and a hybrid vehicle uses at least one electric motor as part of a power source for displacement. Therefore, as described in Patent Literature 1, the electric vehicle must use a large-capacity battery as a source of power for the electric motor.
    However, it takes a long period of time to charge such a large capacity battery which could be accomplished when the battery is under a state of charge (SOC). For this reason, it will be more convenient if the battery can be replaced with a charged battery in such a way that the mobility device can quickly resume travel.
    Although an electric vehicle is not such an electric vehicle of the battery replacement type, the battery must be replaced with a new one when the battery is damaged due to a long period of use with repeated charges. Consequently, the electric vehicle is constructed in such a way that the battery replacement can be carried out as described in Patent Literature 1.

    SUMMARY OF THE INVENTION
    However, in a case where a post-replacement battery (new battery replaced) is not a certified genuine product for the electric vehicle, but a non-genuine, non-certified battery, the post-replacement battery will normally be unsuitable for the electric vehicle from the point of view of performance and physical fitness. In such a case, the electrical components to which power is directly or indirectly supplied from the inadequate battery, an abnormal load will be exerted on the peripheral related parts of the electrical components and the like. Therefore, there is a fear of a malfunction in the electrical components or related peripheral parts.

    To eliminate this requirement, in a case where the battery equipped in the electric vehicle is replaced by the battery without certification, the replacement with the battery without certification is detected and the electric vehicle equipped with the battery without certification is controlled to prevent its displacement.
    However, as the electric vehicle is completely prohibited from self-propelling through this countermeasure, the following problems will be caused especially in a case where a genuine, expensive battery, mounted on the electric vehicle is replaced by a non-genuine battery without certification due to theft that occurs without being noticed during parking. That is, it is difficult to immediately take the electric vehicle to a repair shop or a battery service station and replace the non-certified non-genuine battery again with a certified genuine battery. In addition, the electric vehicle must be moved by a winch. As a result, problems are generated, such as time consumed and hassle-free work, and an increased cost.
    The present invention was elaborated under the circumstances described above. An objective of the present invention is to provide countermeasure equipment for battery replacement without certification for an electric vehicle in which in a case where a battery equipped in the electric vehicle is replaced by a battery without certification; the electric vehicle is maintained in a state capable of self-propulsion; and a power output from an electric vehicle power source is restricted to allow the electric vehicle driver to recognize an abnormal condition of the electric vehicle, so the battery replacement countermeasure equipment without certification can eliminate the problems described above.
    To achieve the above objective, non-certified battery replacement countermeasure equipment for an electric vehicle in accordance with the present invention is constructed as follows.
    Countermeasure equipment for battery replacement without certification for an electric vehicle including an electric motor as at least part of a power source that is driven by electrical power from a replaceable battery, the countermeasure equipment for non-certified battery replacement including: a means of assessing battery suitability to assess whether the post-replacement battery is a certified battery for the electric vehicle or a non-certified battery for the electric vehicle; and a power output restriction means to limit a power output from the power source while allowing the power source to be triggered when the post-replacement battery is assessed to be the non-certified battery for the electric vehicle by the battery adequacy.
    In battery replacement countermeasure equipment without certification for an electric vehicle according to the present invention, in a case where the postPetition battery 870190089152, from 09/09/2019, pg. 13/25
    3/11 replacement is a battery without certification for the electric vehicle, a power output from the power source is restricted, allowing the power source to be activated. Due to the restriction of the power output of the power source, the driver of the electric vehicle can recognize that the post-replacement battery is the battery without certification for the electric vehicle immediately after the displacement of the electric vehicle begins.
    Although the power output of the power source is restricted, the activation of the power source is kept authorized to allow self-propulsion of the electric vehicle under the restriction of the power output of the power source.
    Consequently, it is possible to take the non-certified battery-powered electric vehicle to the electric vehicle to a repair shop or battery service station and replace the battery and replace the non-certified battery with a genuine certified battery at an early stage. As a result, it is possible to prevent the electric vehicle from malfunctioning due to long-term use of the battery without certification.

    Figure 2 is a schematic diagram of the system showing a drive line and an electric vehicle control system as shown in Figure 1 in conjunction with an electric parking locking device.
    Figure 3 is a flowchart showing a control program for controlling battery replacement countermeasure that is run by a motor controller as shown in Figure 2.
    DESCRIPTION OF MODALITIES
    In the following, an embodiment of the present invention is explained in detail with reference to the accompanying drawings.
    Construction of the modality
    Figure 1 shows the electric vehicle 1 equipped with countermeasure equipment for battery replacement not certified according to an embodiment of the present invention. Figure 2 shows a drive line and an electric vehicle control system 1 as shown in Figure 1. The drive line and control system constitute a vehicle displacement drive system.
    The electric vehicle 1 shown in Figure 1 includes front, left and right wheels, 2 and rear wheels, left and right, 3 sustained in a suspended state, and high voltage battery 4 as a high voltage power source that is installed substitutedPetition 870190089152, of 09/09/2019, p. 14/25
    4/11 under a vehicle floor as indicated by the arrow.
    Electric vehicle 1 is an electric car with electric motor 5 only as a power source as shown in Figure 2. Electric motor 5 is driven by the electrical power supplied from the high voltage battery 4, and drives the front wheels, left and right, 2 to allow displacement of the electric vehicle 1.
    From the control of the electric motor drive 5, the motor controller 6 performs the CCC-AC conversion of the electric power from the high voltage battery 4 via an inverter in the battery controller 7, and supplies the AC power to the electric motor 5 under the control of the battery controller 7 (including the inverter). The motor controller 6 controls the electric motor 5 in such a way that the torque of the electric motor 5 is compatible with a calculation result (that is, target motor torque including 0 in a stopped state of the electric vehicle 1, and rotational direction of the motor for forward / reverse travel) on the motor controller 6.
    The high voltage battery 4 is replaced by another fully charged high voltage battery, as indicated by the arrow in Figure 1 when the charge status of the high voltage battery 4 is decreased.
    However, the high voltage battery 4 can be constructed in such a way that when the load is low, the high voltage battery 4 is charged with electrical power from an external power source while being mounted on the electric vehicle 1, and when the high voltage battery 4 is deteriorated due to repeated charges over a long period of time, the high voltage battery 4 is replaced by a new high voltage battery as indicated by the arrow in Figure 1.
    In addition, in a case where the calculation result (target motor torque) on motor controller 6 has negative polarity to require a regenerative braking function of the electric motor 5, the motor controller 6 applies an electrical power generation load to the electric motor 5 via the battery controller (inverter) 7, and allows the battery controller (inverter) 7 to perform AC-DC conversion of the electric power generated by the regenerative braking function of the electric motor 5 and charge the battery high voltage 4 with the resulting DC power.
    At that time, the battery controller (inverter) 7 controls the charge voltage for the high voltage battery 4, and serves to prevent excessive charging of the high voltage battery 4.
    In addition, in this embodiment, as shown in Figure 2, the electric parking locking device 8 as explained below is added to the displacement drive system described above. The electric parking locking device 8 corresponds to an electrical auxiliary equipment in the present invention, and includes a parking locking mechanism (not shown) that acts to lock from
    Petition 870190089152, of 09/09/2019, p. 15/25
    5/11 the front wheel drive line rotationally. The parking lock mechanism is similar to that used in an automatic transmission.
    However, the parking lock mechanism in this mode is operated by an electric parking lock trigger (not shown). The electric parking lock trigger acts in response to the parking lock on / off commands from a parking lock controller (not shown). The electric parking locking device 8 shown in Figure 2 is of an electrically operated type (electrical control type) that is different from a mechanically operated type that is used in an automatic transmission.
    In the following, an electrical power system of the electric parking lock device 8 consisting of the parking lock mechanism, the parking lock driver and the parking lock controller is explained below.
    The electrical power system of the electric parking interlock device 8 includes, for example, a low voltage battery 9 which is a low voltage power source (e.g. 12V), as an auxiliary equipment power source. The parking lock actuator and the parking lock controller of the electric parking lock device 8 are supplied with electrical power from the low voltage battery 9, thereby being activated to properly park the front wheels, left and right, 2 (see Figure 1) as the drive wheels through the parking locking mechanism.
    The low voltage battery 9 is connected to a high voltage circuit between the high voltage battery 4 and the electric motor 5 via the DC / DC converter 10. The motor controller 6 controls an operation of the DC / DC converter 10, thereby charging the low voltage battery 9 with electrical power from the high voltage battery 4 so as to be maintained in an appropriate state of charge.
    As shown in Figure 2, the motor controller 6 receives the following signals to calculate the target motor torque to be introduced in the battery controller (inverter) 7. The signals include ON, OFF signals from the ignition key 11, a signal from the throttle opening sensor 12 that detects the degree of throttle opening APO, a signal from the vehicle speed sensor 13 that detects the vehicle speed VSP, a signal from the brake switch 14 that ON when a braking operation is performed, a signal from the shift lever 15 that is operated when the driver controls a travel configuration such as reverse (R), neutral (N) and forward gear (D) , a signal from the voltage sensor 16 that detects the voltage V of the low voltage battery 9. In addition, the motor controller 6 receives a specific identification code (ID) designated for the individual high voltage battery 4
    Petition 870190089152, of 09/09/2019, p. 16/25
    6/11 through communication with the battery controller (inverter) 7.
    When a request is made to start the displacement drive system by switching the ignition key 11 on, the motor controller 6 calculates a target torque (the magnitude including 0 for stopping and steering) of the electric motor 5 a from the degree of APO throttle opening, the vehicle speed VSP, and the brake switch signal for each travel configuration such as reverse (R), neutral (N) and forward gear (D) that it is controlled via the shift lever 15. The motor controller 6 then transmits a calculation result to the battery control (inverter) 7, used to control the displacement of the electric vehicle 1.
    On the other hand, the electric parking locking device 8 allows the front wheels 2 to automatically enter the parking locking state using electrical power from the low voltage battery 9, when the electric vehicle 1 is in a stationary state without the driver's intention to start the electric vehicle 1.
    However, when the low voltage battery 9 is placed in an uncharged state due to a defect in the high voltage battery 4, a capacity (voltage V) is decreased indicating a low battery voltage state 9 so that finally , the electric parking lock 8 is rendered inoperable. In this case, the electric vehicle 1 cannot enter a parking block state and therefore cannot obtain a parking state with the parking wheels rotationally blocked (front wheels 2).
    In addition, in the electric vehicle 1, a parking brake (not shown) is also constructed as an electrically operated type that is electrically operated by the electrical power from the low voltage battery 9. Therefore, when the capacity (voltage V) of the low voltage battery 9 is reduced, the electric vehicle 1 cannot reach the parking status. Consequently, the inoperable parking block condition of the electric vehicle 1 cannot be ignored.
    To inhibit the occurrence of such inoperable parking block condition, when the low voltage battery 9 is placed in a state where it cannot be charged due to a defect in the high voltage battery 4, the motor controller 6 limits the output of electric motor power 5 according to the reduced capacity (voltage V) of the low voltage battery 9 such that the speed of the VSP vehicle is controlled to an upper limit vehicle speed corresponding to the reduction of the battery voltage V low voltage 9. Thus, the driver of the electric vehicle 1 is induced to stop the electric vehicle 1 (automatic parking block), thereby preventing the electric vehicle 1 from entering an inoperable parking block condition (inoperable parking condition) ).
    Petition 870190089152, of 09/09/2019, p. 17/25
    7/11
    For example, when the voltage V of the low voltage battery 9 is reduced from 12 V as a normal voltage to 11.5 V, the power output of the electric motor 5 is restricted in such a way that the vehicle speed VSP is limited to 50 km / h. When the voltage V of the low voltage battery 9 is reduced to 10 V, the power output of the electric motor 5 is restricted in such a way that the VSP vehicle speed is limited to 20 km / h. When the voltage V of the low voltage battery 9 is reduced to less than 9 V, the power output of the electric motor 5 is restricted to 0 such that the vehicle speed VSP is limited to 0 to thereby forcibly stop the electric vehicle 1.
    When the electric vehicle 1 is stopped by the driver who recognized the abnormal condition of the electric vehicle 1, or is forcibly stopped by cutting off the power output of the electric motor 5 in the absence of recognition of the abnormal condition by the driver, from such an output restriction of electric motor power 5 according to the voltage reduction of the low voltage battery 9, the electric parking locking device 8 is operated to allow the driving wheels (front wheels 2) to automatically enter the parking locking state so that the electric vehicle 1 can be prevented from entering an inoperable parking block condition (inoperable parking condition).
    Countermeasure for Battery Replacement Without certification
    In a case where the high voltage battery 4 is replaced by another fully charged high voltage battery as indicated by the arrow in Figure 1 at a repair shop or battery service station when the charge status of the high voltage battery 4 is decreased, or in a case where the high voltage battery 4 is replaced by another high voltage battery due to theft that occurs without being noticed during parking, if the replaced high voltage battery (post-replacement high voltage battery) does not is an appropriate genuine high voltage battery certified for electric vehicle 1, but a non-genuine high voltage battery not certified for electric vehicle 1, such post-replacement high voltage battery will normally be unsuitable for electric vehicle 1 because of their performance and physical fitness.
    Such a high voltage battery without certification applies an abnormal load to the electrical components to which power is supplied directly or indirectly from the high voltage battery without certification, related peripheral parts of the electrical components, etc., thereby causing a malfunction of the themselves.
    In such a case where the high voltage battery 4 is replaced by a high voltage battery without certification, it is necessary to allow the driver to recognize the fact and perform countermeasures at an early stage. In addition, it is necessary to prevent the non-certified high voltage battery from being used in the future and to stop production of the non-certified high voltage battery.
    Petition 870190089152, of 09/09/2019, p. 18/25
    11/11
    For the reason mentioned above, in this modality, motor controller 6 is configured to execute a control program as shown in Figure 3 and perform a defensive measure against the case where the high voltage battery 4 is replaced by a high voltage battery without certification .
    The control program shown in Figure 3 is executed repeatedly during an operation of the displacement drive system which is started by switching the ignition key 11. First, in step S11, it is evaluated whether or not it is the moment immediately after the ignition key 11 is turned on (it is the first time the ignition key 11 is turned on).
    When it is assessed that it is the moment immediately after the ignition key 11 is switched on, the logic flow proceeds to step 312 through step S15 in which it is assessed whether or not the high voltage battery 4 is a genuine certified product for the vehicle. electric 1. If it is the time immediately after the high voltage battery 4 is replaced by another high voltage battery 4, it is assessed whether the post-replacement high voltage battery 4 as an object to be evaluated is a product or not. genuine certified for vehicle 1. When carrying out this evaluation, first in step S12, a specific identification code (ID) for post-replacement high voltage battery 4 is read and is referred to a group of relative identification codes (ID) to the genuine high voltage battery.
    Then, in step S13, it is evaluated whether the identification code (ID) for the post-replacement high voltage battery 4 is included in the group of identification codes (ID) for the genuine high voltage battery or not, for thereby assessing whether the post-replacement high voltage battery 4 is the genuine product certified for electrical product 1 or not.
    When in step S13, it is assessed that the specific identification code (ID) for the post-replacement high voltage battery 4 is included in the group of identification codes (ID) in relation to the genuine high voltage battery, it is recognized that the post-replacement high voltage battery 4 is the certified genuine product for the electric vehicle 1. The logic flow proceeds to step S14. In step S14, the battery identifier BFLAG is set to 1 indicating that the post-replacement high voltage battery 4 is the certified genuine product.
    However, when in step S13, it is assessed that the specific identification code (ID) for the post-replacement high voltage battery 4 is not included in the group of identification codes (ID) in relation to the genuine high voltage battery, or when the post-replacement high voltage battery 4 does not even have any identification code (ID), it is recognized that the post-replacement high voltage battery 4 is a non-genuine, non-certified product for the electric vehicle 1. The logic flow proceeds to step S15 in which the battery identifier BFLAG is set to 0 indicating that the battery of high
    Petition 870190089152, of 09/09/2019, p. 19/25
    9/11 post-replacement voltage 4 is the non-genuine, non-certified high voltage battery. Consequently, step S13 through step S15 corresponds to a means of assessing battery suitability according to the present invention.
    When in step S11, it is evaluated that it is not the moment immediately after the ignition key 1 is turned on, but a second or more moments, the logic flow proceeds to step S16 until step S18 in which the engine power output control Electric 5 is performed as follows according to the result of the battery suitability assessment, described above (battery identifier BFLAG).
    In step S16, it is evaluated whether the battery identifier described above BFLAG is 1 or not, that is, whether the post-replacement high voltage battery 4 is a certified genuine product for electric vehicle 1 or a non-genuine non-certified product for the electric vehicle 1.
    When the BFLAG battery identifier is assessed to be 1 (that is, when the post-replacement high voltage battery 4 is assessed to be a certified genuine product), the logic flow proceeds to step S17 in which the power output of the electric motor 5 is controlled in a normal manner as explained above. However, when the BFLAG battery identifier is rated 1 (that is, when the post-replacement high voltage battery 4 is rated as a non-genuine, non-certified product), the logic flow proceeds to step S18 in which the power output of the electric motor 5 is limited differently from the normal power output control described above.
    The engine power output restriction in step S18 is performed to allow the driver to recognize an abnormal condition in which the post-replacement high voltage battery 4 is a non-certified non-genuine product, and to replace the post-high voltage battery replacement 4 with a genuine product again at an early stage. For example, the motor power output restriction setting described above, which is adopted when the low voltage battery voltage 9 is reduced to 10 V due to a defect in the high voltage battery 4, is applied to restrict the output of electric motor power 5 such that the VSP motor speed is limited to 20 km / h while allowing the electric motor 5 to be started.
    Modality Effects
    According to the countermeasure control for battery replacement without certification, described above, of this modality, in a case where the post-replacement high voltage battery 4 is a high voltage battery without certification for the electric vehicle 1, the power output of the electric motor 5 is limited in such a way that the speed of the VSP vehicle is controlled to 20 km / h while allowing the electric motor 5 to start. Due to the motor power output restriction, the driver of the electric vehicle 1 can recognize a abnormal condition in which the post-replacement high voltage battery is a
    Petition 870190089152, of 09/09/2019, p. 20/25
    10/11 high voltage without certification immediately after starting the displacement of the electric vehicle
    1.
    However, even when the power output of the electric motor 5 is limited, the displacement of the electric motor 5 is still allowed so that the electric vehicle 1 can achieve self-propulsion at the VSP vehicle speed of no more than 20 km / h under the engine power output restriction described above. Consequently, it is possible to carry out defensive measures at an early stage in order to take the electric vehicle 1 to a repair shop or to a battery service station and replace the non-certified high-voltage battery without certification with a certified high-voltage battery. As a result, it is possible to inhibit the malfunction of the electric vehicle 1 due to the use of the non-genuine high voltage battery without certification for a long period of time. In addition, it is possible to avoid problems such as time consuming and cumbersome work as a result of the displacement of the electric vehicle 1 by a winch and an increased cost.
    In addition, the driver of the electric vehicle 1 can recognize that the post-replacement high-voltage battery is a non-certified high-voltage battery and can immediately replace the non-certified post-replacement high-voltage battery with a certified high-voltage battery . Therefore, it is possible to prohibit the use of the high voltage battery without certification and inhibit the production of such high voltage battery without certification.
    Additionally, in this modality, from the adequacy assessment of the high voltage battery 4, it is assessed whether the post-replacement high voltage battery is a high voltage battery certified for the electric vehicle 1 or a high voltage battery without certification for electric vehicle 1 by reference to an identification code (ID) assigned to an individual high voltage battery for a predetermined identification code (ID). Thus, the assessment of the suitability of the high voltage battery 4 can be done promptly and instantly in an advantageous way only by checking the identification code (ID).
    In addition, when the power output of the electric motor 5 is limited in a case where the high voltage battery 4 is replaced by a high voltage battery without certification, the motor power output restriction setting, described above which is adopted when the low voltage battery voltage (parking block power source) 9 is reduced to 10 V due to a defect in the high voltage battery 4, it is applied as such to limit the power output of the electric motor 5 from such that the VSP vehicle speed is limited to 20 km / h. Consequently, it is not necessary to design a special control configuration separately, and the predetermined objective, mentioned above, can be achieved through such ready control in order to apply an existing engine power output restriction configuration without any change.
    Petition 870190089152, of 09/09/2019, p. 21/25
    11/11
    Additionally, from the power output restriction of the electric motor 5, the power output restriction of the motor is performed in such a way that the VSP vehicle speed is limited to 20 km / h. As a result, the driver is warned about replacing a high-voltage battery without certification by restricting the speed of the vehicle which makes the driver more sensitive to an abnormal condition. Therefore, the driver can recognize this event with more certainty, and the above effects can be noticeably achieved.
