Abstract:
1. A charging system for a mild hybrid vehicle, comprising: an engine; an integrated starter and generator (ISG) connected to the engine and configured to generate 3-phase AC electricity and to start the engine; an inverter configured to convert the 3-phase AC electricity generated at the ISG into DC electricity and configured to convert the DC electricity into the 3-phase AC electricity and to deliver the converted 3-phase AC electricity to the ISG; a super capacitor configured to receive the DC electricity from the inverter and be charged by the DC electricity, and to deliver the charged DC electricity to the inverter; a DC-DC converter connected to the inverter and configured to receive the DC electricity from the inverter and drop voltage; a battery configured to receive the DC electricity from the DC-DC converter and to be charged by the DC electricity; and means for preventing reverse charging mounted on a path between the super capacitor and the battery of the mild hybrid vehicle and configured to prevent energy from flowing from the battery to the super capacitor.
