  • Charging system for mild hybrid vehicle
    Patent number: 9242570
    Abstract: A charging system for a hybrid vehicle which prevents a super capacitor from being reverse charged. In the illustrative charging system a DC-DC converter is connected to the inverter and configured to receive the DC electricity from the inverter and drop voltage. A battery is configured to receive the DC electricity from the DC-DC converter and to be charged by the DC electricity. Finally, a means for preventing reverse charging is mounted on a path between the super capacitor and the battery and is configured to prevent energy from flowing from the battery to the super capacitor.
    Type: Grant
