    专利说明:

    [0001] The present invention generally relates to a multifunctional electrical device for a motor vehicle. Nowadays, electric or hybrid motor vehicles are more and more widespread. In fact, their reduced emission of pollutants and their low fossil fuel consumption make them prime target vehicles for consumers concerned about their environment and their budget. In order to constantly improve these vehicles, electric motors, batteries and various load circuits as well as their architecture have been greatly improved. In general, electric and hybrid vehicles comprise a charging device for the vehicle battery. Indeed, in order to recharge the vehicle battery it is necessary to connect it to an external outlet emitting a DC voltage. Such a charging device is known as including among others an AC / DC rectifier including a transformer for charging the battery with a current at a predetermined voltage. Also present on this type of vehicle is a so-called DC / DC conversion device that allows the battery to power various electrical consumers present on the vehicle. Such a converter also comprises an AC / DC rectifier and a transformer, in particular.
    [0002] It is known in the prior art that electric or hybrid motor vehicles are expensive because of their intrinsic components and require an optimization of the weight always reduced especially because of the weight of the batteries which remain heavy. While the weight of the batteries has been reduced over the years, in particular by abandoning the fuel cells, it has also been necessary to find new ways to reduce the costs, the volume and the weight of the electrical components installed in the vehicle.
    [0003] For example, in US 2009 103341 describes a power distribution device in a hybrid vehicle comprising different AC / DC converters, DC / DC and a battery. This device can operate in three modes (charging from an external power supply, 5 boost and charging by the onboard network). In this device, the same component is used in the three modes. However, this device proposes an architecture for covering two life situations namely a charge of the battery via a converter, a switching element and a rectifier, and a supply of the motor via the converter switching element 10 and an inverter. However, this device is limited to both modes of operation and adds a device, a switch, which increases the weight of the vehicle. Also, in WO 2014/180606 there is described a device for distributing power in a vehicle, whose architecture, that is to say the arrangement and connection of the organs, is such that an external current can be fed into a converter. However this device does not solve the problem mentioned above. An object of the present invention is therefore to meet the drawbacks of the document of the prior art mentioned above and in particular, first of all, to provide a multifunction electrical device capable of assuming a function of feeding and recharge by minimizing its cost, weight and volume. For this purpose, a first aspect of the invention relates to a multifunction electrical device for a vehicle comprising a battery charging circuit arranged for connecting an external AC power supply having a first voltage to a battery of the vehicle having a second voltage, a circuit of current conversion arranged to connect the battery of the vehicle having a second voltage to vehicle-mounted electrical consumers having a third voltage, and control means arranged to drive the device in a battery charging mode or a battery mode. power supply of the electric consumers or a mode simultaneous charging and powering combining the first two modes, charging mode of the battery and supply simultaneously, characterized in that the battery charging circuit and the current conversion circuit share a reversible common transformer 5 arranged to r be switched by the driving means so as to transform the first voltage into the second voltage into the charging mode and the second voltage into the third voltage into the power mode and finally the first voltage into the second and third voltage simultaneously in the charge and simultaneous power mode. In this way, the components of two separate devices are pooled to obtain a single device having both functions thus gaining in cost, volume and weight. Advantageously, the battery charging circuit and the current converting circuit further share all the components between the transformer and the battery. Thus, the costs and the complexity of the device are reduced. A particularly interesting realization is that the shared components include MOS. In this way, it can have different functions.
    [0004] Advantageously, the MOS are arranged to be configured by the driving means so as to have a diode bridge function in charging mode and in simultaneous charge and power mode and an inverter function in power mode. Thus, the different modes of operation are executed reliably.
    [0005] Advantageously, the transformer comprises a first low voltage winding arranged to be connected to the external power supply, a second low voltage winding connected to the battery and a very low voltage winding connected to the consumers. In this way, the transformer is simple to manufacture.
    [0006] A particularly interesting embodiment is that the voltage of the low voltage windings is in the range of 170 V and 500 V and the voltage of the very low voltage winding is in the range of 6 to 18 V. Thus, the device can be used with a wide variety of equipment. Advantageously, the electrical device further comprises cooling means common to both circuits. In this way, the costs and complexity of the device are further reduced. Advantageously, the first voltage is 230 V or 110 V, the second voltage is between 170 V and 500 V and the third voltage is between 6 V and 18 V. Thus, the device can be connected to a mains socket. conventional. A particularly interesting embodiment is that the electrical device also comprises a microprocessor common to both circuits. In this way, the costs and complexity of the device are further reduced. A second aspect of the invention is a vehicle comprising an electrical device according to the first aspect of the invention. Other features and advantages of the present invention will appear more clearly on reading the following detailed description of an embodiment of the invention given by way of non-limiting example and illustrated by the appended drawing, in which: FIG. 1 represents a schematic diagram of the electrical device of the present invention.

Preferably, a voltage range of the low voltage windings is in the range of 170 V and 500 V and a voltage range of the very low voltage winding is in the range of 6 to 18 V.
    [0008] In addition to the components between the transformer 3 and the battery, the electrical device further comprises a microprocessor 13 and cooling means 14 common to both circuits. In addition to the common part of the two circuits comprising the transformer 3, the charging circuit 11 also comprises load circuit specific components such as an AC / DC converter 6, a power factor corrector 7 and a converter. DC / AC 8 between the transformer and the mains socket. In the same way, the current conversion circuit 12 further comprises a filter 9 and a converter 10 AC / DC / 10 between the transformer 3 and the consumers.
