11005286 · 2021-05-11 · ·

A dual actuated power pack (300) comprises a battery (104) and first (101) and second (102) electric motors, as well as a power generator (103). The first electric motor (101) is powered by the battery (104) and the second electric motor (102) by a grid (106). The first and second electric motors (101, 102) are mechanically coupled (108) with each other so that when said second electric motor (102) is powered, said second electric motor (102) actuates (109) said power generator (103) and said first electric motor (101) at the same time, whereupon the first electric motor (101) functions as a hi-power battery charger and recharge the battery (104) when said second electric motor (102) actuates (109) the power generator (103). When the second electric motor is not used, the first electric motor (101) is powered (104, 105), and the power generator (103) is actuated (108) by said first electric motor (101).

Vehicle power supply system

A power supply system includes a first drive motor, a second drive motor, a first power line to which a first inverter and a first battery are connected, a second power line to which a second inverter and a second battery are connected, a voltage converter that converts a voltage between the first power line and the second power line, and an ECU that operates the first and second inverters and the voltage converter and controls charging and discharging of the first and second batteries. In a case where total required power is larger than first outputtable power of the first battery, the ECU discharges a shortage of power from the second battery to the second power line, wherein the shortage of power is obtained by excluding an amount that is output by the first battery from the total required power.
