Abstract
Power systems capable of charging chargeable systems at a power greater than or equal to a predetermined value are disclosed. Example embodiments may be a power system for an electric vehicle. The chargeable system may be an electric vehicle. Some embodiments are capable of peer-to-peer fast charging of electric vehicles at a power greater than or equal to 50 kW.
Claims19
A power system comprising:
- a multi-phase motor having an electrically neutral Connection;
- a direct current (“DC”) charge plug;
- a traction battery electrically connected to a bus negative, the bus negative being connected to the DC charge plug;
- a traction inverter electrically connected to the multi-phase motor via phase connectors, and electrically connected to the traction battery;
- a contactor electrically connected to the motor neutral connection and electrically connected to the DC charge plug;
- and
- a controller electrically connected to the multi-phase motor and the traction inverter, the controller configured to control power by using motor inductance and inverter switching controls to either increase or decrease voltage to the DC charge plug.
