Abstract

Embodiments include a power processing system and methods of its operation in a plug-in electric vehicle. The power processing system includes at least one AC electric motor, a bi-directional inverter system, and an electronic control system. The electronic control system provides a drive function by providing first control signals to the bi-directional inverter system which, in response, draws DC electrical power from a DC energy source, converts the DC power to AC power, and provides the AC power to windings of the at least one AC electric motor. The electronic control system also provides a charging function by providing second control signals to the bi-directional inverter system which, in response, draws AC power from the windings of the at least one AC electric motor, converts the AC power to DC power, and provides the DC power to the DC energy source in order to recharge the DC energy source.

Description

technical field [0001] Embodiments of systems and methods relate to power processing systems and their methods for use in plug-in electric vehicles (eg, full electric vehicles and hybrid electric vehicles). Background technique [0002] Conventional plug-in electric vehicles (e.g., full electric vehicles or hybrid electric vehicles) use on-board or off-board (off-board) battery chargers to charge the vehicle's battery from a utility (utility) alternating current (AC) power outlet. Recharge. When not driving the vehicle (eg, when parking the vehicle overnight), the operator of the vehicle may connect the vehicle to an electrical outlet via the battery charger. The battery charger can then draw current from the utility to recharge the battery. [0003] Conventional battery chargers have several implications with respect to the physical, manufacturing and / or operating characteristics of the vehicle. For example, including an on-board battery charger in a plug-in electric veh...
