Fuel cell plug-in hybrid vehicle with charger for a battery charge from the grid

摘要

In a fuel cell plug-in hybrid vehicle having a fuel cell (20) having an anode side (19) and a cathode side (21) with a compressor (34) connected to the cathode side (21) via an air supply line (33). is connected to an electric motor (36), which is in drive connection exclusively with the compressor (34), with a converter (38) which is electrically connected on one side to the motor (36) and on the other hand to a high-voltage battery (42), and with a controller (60) which switches the vehicle into two different operating states, in a first operating state, the high-voltage battery (42) supplies the motor (36) with electrical power via the converter (38), so that the electric motor (36) drives the compressor (34). In a second operating state, an electric voltage is supplied from a network to the motor (36) or the converter (38) via a power supply line (70). The motor (36) may preferably vary the mains voltage in amplitude. The optionally changed voltage is applied to the converter (38), which converts it into a DC voltage, which is applied to the high-voltage battery (42).
