    DETAILED DESCRIPTION Figure 1 shows a first embodiment of a voltage conversion device 10 according to the invention which comprises a voltage converter 11 which. for example, can be connected to a battery, which delivers a first lower voltage of between lOV and 3OV, especially a l2V 'or 24V battery.
    The voltage converter ll as. included in the voltage conversion device is designed to convert this first, for example 12V or from the battery supplied lower voltage, for example 10 15 25 24V, to a second, higher, voltage for supplying a number of consumers.
    The voltage converter ll is a DC / DC converter and it is designed to convert the first lower voltage to a second higher DC voltage which. preferably does not exceed the current limit value for high voltage, ie. it is a low voltage, and depending on the legislation it can be slightly below 5OV or 60V, especially 48V. In alternative embodiments, the second voltage can of course be a high voltage, but then an adapted installation and higher safety requirements are required. In some cases, however, more advanced installation equipment etc. can be compensated by the fact that smaller motors can be used, for example increased permitted power outlets.
    The voltage conversion device 10 comprises or is connected to a control function 12 which controls the voltage converter 11.
    In particular, it is designed to be able to transfer the voltage converter between a first passive mode which is a sleep mode and in which substantially no current is consumed and an active mode in which one or more consumers can be supplied.
    The control function 12 is designed to be able to transfer the voltage converter from active to passive mode if / when given criteria are met, which may for example consist of no consumer having any outstanding request for supply or no consumer having consumed power for a given period of time. Other criteria are of course also possible, ie. the essential thing is that the voltage converter is only in active mode when supply is really required to save battery capacity and ensure that no power is drawn unnecessarily and optimize the utilization of available battery charge, especially to avoid idle losses.
    Waking up of the voltage converter can take place in different ways, for example by a user when a consumer is to be used with a control button, a remote control, etc., or via the CAN bus. If the CAN bus is not 'used for wake-up (transfer' to active mode), a separate circuit can be used for this purpose.
    Waking up especially via the CAN bus is fast and only takes a few ms (milliseconds). information goes on CAN- all, It is especially advantageous if. all the bus, the CAN bus can transmit a lot, especially information with just one cable. This is also advantageous in itself because then only one cable is needed, because this avoids * having a lot of cable, which is advantageous for several different reasons, location reasons, cost reasons, space reasons, and avoids the risk of forming cable entanglements.
    As shown in Fig. 1, the voltage conversion device 10 is connected to a number of consumers 11m1,1,1M, 113 so that these can be supplied by means of voltage converters 11. In the exemplary embodiment shown, the connecting means comprise a second connection network 15 for supply between the voltage converter 11 and respective consumers Consisting of wires or cables.
    Because the DC / DC converter 11 converts the lower battery voltage to a higher DC voltage, for example 48V, significantly thinner cables can be used than in hitherto known devices where the thickness of the cables is a problem, especially when they are to placed in confined spaces such as on a recreational boat. Thick cables are partly bulky, partly they have to be bent or bent, which can be problematic and complicate suitable cable laying. Such thick cables are also expensive, which is an additional disadvantage. With a voltage conversion device according to the invention, the required cable dimensions can be reduced from, for example, 40 mm to about 8 mm 2.
    Another advantage is that electric motors become more efficient if a higher voltage is used, this in special designs, without entering the high voltage range, where completely different requirements are placed on equipment. on the safety system Såson1 mentioned above, the second voltage can of course alternatively be a high voltage.
    The voltage conversion device 10 also comprises a, here called first, connection network 16 for communication between the control unit 12 of the DC / DC converter and the consumers 11m, 11.1, 11y. In the embodiment shown, this connection network is a low-speed CAN network (or a CAN bus). ), on which also an information remote control 19 can be connected, on which e.g. can be sent from the consumer that the DC / DC converter is started or that it requests supply.
    The CAN bus can be operated with the 48V system (here), which in some embodiments is achieved by building specially adapted circuits. Alternatively, the CAN bus can be operated separately, but it must then withstand the higher voltage converted by the voltage converter. 10 15 20 25 30 In some embodiments, the CAN bus runs on the lower input voltage (eg 12V). The CAN cable can run on e.g. 5V inside the CAN circuit.
    Information can be sent from the control unit 12 of the voltage conversion device that the requested supply can be delivered or that a lower supply capacity is only available, and so on. Communication. can take place between a remote control 19 with. a transmitting and a receiving functionality with which thus supply of a consumer can be requested etc. as described above. This can also be done via control buttons on a control panel 14 or the like. respective functionalities are on or provided. Alternatively, these consumers (not shown here) can in addition to 'on one or more consumers, also through a remote control and / or a control panel with control buttons. In particular, with a start signal power can be reserved for a consumer, especially the power that the consumer draws.
    The control function 12 is designed to control the voltage converter 11 to allow supply of one or more consumers who. request supply depending on available supply capacity and fulfillment of given criteria.
    Suitably, the control function 12 continuously collects (or at discrete times, or on request) information about the available capacity of the voltage converter and can keep such information in information holding means 18. It can also be provided with such information in other ways. lO l5 20 25 30 Criteria can be specified in different ways according to different designs. In the simplest embodiment, consumers can simply be supplied in turn, ie. the consumer who first requests supply will be supplied, and if additional consumers then need to be supplied, these will be supplied to the extent of the remaining capacity, or * alternatively the power will be shared. between them. According to another alternative, previous consumers are switched off, or power outlets are allowed after the last added consumer has been allowed to withdraw the power they need, or the power is shared between them.
    Advantageously, it is possible, for example via control panel l4 or via remote control l9 or via operation directly with a button or the like. on a consumer give that consumer priority and, where appropriate, terminate or at least reduce supply because. this is the consumer currently prioritized by other consumers who absolutely must be supported.
    According to other embodiments, the criteria include priority information for different consumers and priority information can be kept in storage means 17 which is either included in the control unit or which communicates with it.
    The priorities, as well. criteria, can be either fixed or * dynamic, i.e. changeable. It is too. possible to add and remove new consumers and give them some individual priority, for example according to different priority classes, etc. In this prioritization information can also be kept effect, included or information regarding to what extent, or if, or supply sharing is to be applied, so that e.g. indicates whether power sharing shall be applied 10 15 20 25 30 10 if sufficient supply power is not available when a consumer requests supply but if only a fraction of the requested capacity is available and if and how in that case available capacity is to be shared between different consumers, which consumers allows sharing, etc.
    The prioritization and allocation of supply to different consumers can be controlled in many different ways, from completely manual to automatic, mechanically controlled or computer-controlled.
    In some embodiments, temporary change is allowed, e.g. up- or down-prioritization of a certain consumer, which for example can * be performed by1 a shortcut on the voltage converter, the consumer, a remote control or a control panel, or on one or more thereof.
    Consumers can be added, replaced, deleted and manually or automatically given different priorities.
    According to an advantageous embodiment, consumers are given an identity during assembly, during installation. This can be done in different ways, e.g. genon1 a login procedure in which consumers are given an identity. For example, for activation, during assembly, an activation button sonl is connected. to a consumer or to the user can be used. When the activation button is activated, a request is sent to (the user and) the DC / DC converter, or only to the user, who. then sends a signal to the DC / DC converter over the communication network.
    Assembly and start-up can, for example, be done in such a way that all components are first assembled, consumers, cable is pulled, power l0 l5 20 25 30 ll is switched on, questions are sent out to all assembled consumers, who return an answer. They are then given a name or an identity. In advantageous embodiments, the voltage converter is equipped with a display and a user interface.
    If instead of a CAN bus a wireless communication network is used, this procedure can be performed in a similar manner. If instead discreet. wires were used as. communication networks can, for example, so-called jumper cables and micro-switches are used with e.g. 5-digit or other suitable code.
    By using a prioritization principle, a smaller voltage converter can be used than if. a voltage converter is used which allows all consumers to be connected at the same time, which is advantageous.
    Priority for consumers can be programmed in some more advanced designs, e.g. in connection with assembly as described above.
    Fig. 2 shows an alternative embodiment with a voltage conversion device 20 with. a voltage converter 2l for supplying consumers l2m] ¿1, l fi, where 122 shall denote other consumers. The control unit 22 here comprises information gathering or information holding means for holding information about remaining available capacity and storage means for holding information about criteria, in particular prioritization information, as described above.
    That which. essentially different from this embodiment from the embodiment described above according to Fig. 1, is that here the CAN bus runs on the first connecting means 25 and for both communication (CC) 10 15 20 25 30 12 with the control unit and for supply (V) a common , combined network. The example shown also shows a remote control 29 and a control panel 24. In other respects, the device functions as described above and can be varied in a similar manner.
    Fig. 3 shows a further example of a voltage conversion device 31, 32, connected, herewith. a separate control unit or comprising, information holding means and storage means (not shown) for holding information on current supply capacity and priority information (and identity information regarding consumers), respectively. The control unit is arranged here above, at the supply voltage from the battery.
    The voltage conversion device is connected via 133,131,132 (132 supply connection 35 to consumers schematically referring to other 48V consumers) for supply as described above, and the consumers are provided with respective control means, for example control buttons or similar 34L342.34y Control means in the form of control buttons Of course not necessary, but some consumers may be equipped with it. Such control means can e.g. be arranged directly on the consumer.
    Alternatively, one or more consumers may be controllable exclusively, or as a complement, via a remote control 39.
    Here it is indicated that the remote control 39 can control all consumers or their controls, but it can of course be the case that only one or some of the consumers can be controlled via remote control, or alternatively that no one can do so. Communication with the control unit 32 can in some embodiments take place via the example shown consists of to a connection 361 which in the discrete cables are connected to respective consumers, or * their separate. controls. With. discrete. cables, then both identity and priority information can be provided directly to the control unit 32, which may, for example, be provided with contacts for certain consumers or for a certain priority in a simplest embodiment.
    Of course, even in this case with discrete communication lines, collection of control information can take place by direct indication or input to the control unit or programmed into it if it is more advanced.
    In simpler embodiments, regardless of location and possible design, discrete cables from the respective consumer to the control unit can be placed on different pins on an input device / control unit, for example in such a way that different pins are used for different priorities. Alternatively, identity and / or priority can be programmed at. connection of the respective line from a consumer. Even in_ this. In this embodiment, a wireless communication network 362 may be used as a complement to the discrete communication network 361, or may be used for certain consumers who support wireless communication.
    Fig. 4 shows another example of a voltage conversion device 40 with. a voltage converter 41 son1 can supply via a second connection means 45. a number of 1w, 1 fl, 1 Q, having ar are provided with 441,442,443 as consumer communication units enables wireless communication with the control unit 42, i.e. in this exemplary embodiment, the first connection means for communication consists exclusively of a wireless network 46. The control unit is a module 56 for wireless means 47 and here also comprises communication, information-holding priority information storage means 48 as described above.
    It should be clear that in all exemplary embodiments, the voltage converter may consist of a unit comprising all the necessary functions regarding storage of information, handling of information, etc. For illustrative reasons, however, the control unit is shown to be arranged separately from the voltage converter; which, however, also indicates another advantageous embodiment.
    Fig. 5 is a schematic flow diagram. which describes the procedure when a consumer U sends a supply request, 100. This request can be sent on CAN, over a discrete connection, where a consumer is simply connected or * a user presses a button, through. manual programming on the control unit or wirelessly by a user using * a remote control. The request is sent to / processed in the control unit which examines whether the DC / DC converter is in active mode or not, 101. This can be done in different ways, for example by seeing if the other, higher voltage is on the supply line from the voltage converter.
    If it is not in active mode, the controller ensures that it is transmitted to active mode, 101A, for example by activating a switch or on the chip. 101B, Thereafter, the consumer is allowed to withdraw the requested power, i.e. information is sent to consumer U that it can take out the requested power (current) provided that it is available, which it is, however, expected to be because the DC / DC converter has been in passive mode.
    If. The DC / DC converter, on the other hand, has been found to be in active mode, can be re-examined. the. requested effect. is available, 102, by comparing the requested power with information in means of available information regarding available power. If the requested power is available, it is delivered, ie. withdrawal allowed, 101B. If, on the other hand, the requested power is not available from the DC / DC converter, it is examined whether power sharing is applied, 103 (either in general or if this is to be applied in the current case and / or for the requesting consumer). If not, the request is denied and information about it is sent via CAN to consumer U, 103A.
    If, on the other hand, power sharing is applied, the available power is shared between already supplied consumers consumers 104. and request It can be done in different ways, either poured into this is appropriate, the power (power) is shared or certain consumer or if the consumers belong to different priority classes, how available supply capacity should in that case be distributed between consumers. This can be done in many different ways depending on the information. held. In a simple case, the requesting consumer is simply provided with the remaining capacity.
    Fig. 6 is a flow chart. which illustrates an alternative method according to the invention and shows an example of how prioritization information can be poured and used. It is assumed that a request for supply of a consumer 1 is sent on a CAN 10 15 20 25 30 16 where the request contains information on the requested power, 200. 201, bus, Then it is examined whether the DC / DC converter is in active mode, and if not, it is transmitted to active mode, 201A, as described in connection with Fig. 5, and it is examined whether the requested power is available, 202. If the requested power is then available, the requested power 202A is supplied, information thereon to (allow withdrawal ), is transmitted via the CAN consumer and is registered in information holding means in or in connection with one or connected to either 202B, control unit in the voltage converter; that consumer 1 is provided with the delivered power, or in a simplified embodiment that a certain quantity is delivered to a consumer.
    If, on the other hand, the requested effect is not available, it is examined in communication with storage agents that keep priority information if there are other consumers who have a lower priority and who are currently supplied, 203.
    If it is determined that there are no lower priority consumers, it is examined whether power sharing is applied, 203A; if not, request 203B is rejected, and information about this is sent via CAN to consumer 1.
    If, on the other hand, power sharing is applied, either available power is delivered or the power is shared with the same priority consumer or in another desired way, according to the given 203C. which to priority information, Then power delivered to consumers is registered 1. If, on the other hand, it is determined that there are lower priority consumers who are delivered (allowed at the time supplied, requested power output) to consumer 1 while the power supply is lower 10 15 20 25 30 17 priority consumers either terminated or reduced to the extent necessary, 204, and registration is made by which consumer is supplied which power (or power).
    Fig. 7 shows a further alternative embodiment according to the invention. Here it is assumed that a consumer X is activated via a control button or the like, either on the consumer himself or on a control panel, separately or in connection with the voltage converter or its control unit, or via a remote control, 301. A request for supply including information on requested power ( current) is transmitted either via a discrete line or wirelessly to the control unit CU, 302 of the voltage converter device. The control unit determines or retrieves information about. what effect that. is available in the DC / DC converter, 303. If the requested power is available, 304, consumer X is allowed to withdraw the requested power from the DC / DC converter via the supply network, 304A, i.e. consumer X is informed that a given power or desired power can be charged.
    Thereafter, the available residual power is recorded in information holding means 304B. However, if the requested power is not available, check if priority is applied, 305. If priority is not applied, check if power sharing is applied, 305A. If this is not the case, request 305C is rejected, i.e. consumer X is not allowed to supply 'and. notified directly or indirectly.
    However, if it is determined that prioritization is applied, it will be re-examined. X has the same priority as. already supplied or supplied consumers. If yes, it is investigated whether power sharing is applied, 305A above, or if other criteria are applied, for example if first requesting consumer should be allowed to supply or if a later or last requesting consumer should instead be allowed supply, etc. Many alternatives are possible. However, if there is no consumer who has the same priority, it is examined whether consumer X has a higher priority, i.e. consumer 307C. 307. If not, request, X is not allowed supply, However, if consumer X has a higher priority, the supply of lower priority consumers 307B, 307A is reduced or terminated. and supply of consumer X is permitted, which is registered, 304B.
    It should be clear that the invention is not limited to described embodiments but can be varied in a number of ways within the scope of the appended claims. The device can be specially designed for use on a boat, but this of course does not exclude use in other contexts where similar requirements and needs exist, e.g. in connection with different types of accommodation, devices or means of transport or transport.
    It should also be clear that the content of the described exemplary embodiments can be freely varied and combined with one another.
