Electric vehicle system for charging and supplying electrical power

A power system to provide power between an energy storage device, an external charging source/load, an onboard electrical power generator, and a vehicle drive shaft, the power system comprising:

• at least one energy storage device electrically connected across a dc bus;
• at least one filter capacitor leg comprising at least one filter capacitor and electrically connected across said dc bus;
• at least one power inverter/converter electrically connected across said dc bus;
• at least one multiphase motor/generator, each motor/generator comprising stator windings electrically connected at one end to form a neutral point and electrically connected on the other end to one of said power inverter/converters;
• a charging-sourcing selection socket electrically connected to said neutral points and said external charging-source/load;
• and at least one electronics controller electrically connected to said charging-sourcing selection socket and said at least one power inverter/converter;
• whereby the switch legs in each of said inverter/converters selected by said charging-source/load socket collectively function as a single switch leg and said motor/generators function as an inductor;
• wherein the external charging source/load is capable of both providing power to the power system and receiving power from the power system based on a selection of the charging-sourcing selection socket.
