Embodiment Construction

[0044] figure 1 A network 10 with at least two energy management systems 12 is schematically shown. Furthermore, two motor vehicles 14 are shown, each having an energy store 16 and a solar cell 18 . In this case, the solar cell 18 can generate electrical energy, which can be stored in the energy store 16 . Furthermore, each motor vehicle 14 has a charging device 20 which is in each case electrically connected to the solar cell 18 and the energy store 16 of the associated motor vehicle 14 . In this case, the charging device 20 includes a converter module in which the functions of a DC voltage converter, an inverter and a rectifier are integrated. In this case, two charging devices 20 of two motor vehicles 14 are electrically connected to one another by means of an electrical connection 22 , for example by means of a power cable. For this purpose, the respective charging device 20 can have a plug. In the present case, each of the energy management systems 12 includes one of ...

Abstract

The invention relates to a power management system (12) for a motor vehicle (14), the motor vehicle (14) comprising at least one energy storage device (16) and at least one solar cell (18) for generating electrical energy, said system being provided with a charging device (20) which is designed to both charge the energy storage device (16) with electrical energy from an external energy souce and to supply an external consumer with electrical energy from the energy storage device (16) and / or of the solar cell (18), the charging device (20) comprising a DC voltage, a converter, an inverter and arectifier.

Description

technical field [0001] The invention relates to an energy management system for a motor vehicle. Background technique [0002] A big challenge when building an electrically driven motor vehicle is its energy supply. It can therefore be provided that the motor vehicle is equipped with at least one solar cell which can be activated by means of light radiation to generate electrical energy and thus charge an energy store of the motor vehicle. In this case, however, the use of the motor vehicle can only be adjusted temporally to the solar radiation to a condition. For example, it can happen that the motor vehicle is not used during the day when the solar radiation is high, so that more current can then be generated by the corresponding solar cell than can be consumed by the energy store of the motor vehicle. This potentially generateable energy is thus not used. This excess electrical energy can thus be supplied by the motor vehicle to other electrical consumers. Conversely,...
