Abstract
In some aspects, an electric vehicle power system may comprise two or more electrically connected power modules connected to a system communication bus. Each power module may comprise a rechargeable battery electrically connected to a DC bus, an inverter circuit electrically connected to the DC bus, and at least one of a single-phase rectifier circuit electrically connected to the DC bus or a multi-phase rectifier circuit electrically connected to the DC bus. A local controller configured to send control signals may be connected to the rechargeable battery, the inverter circuit, and the at least one of the single-phase rectifier circuit or the multi-phase rectifier circuit. The single-phase rectifier circuit may be configured to convert a single-phase AC power signal into the DC voltage of the DC bus. The multi-phase rectifier circuit may be configured to convert a multi-phase AC power signal into the DC voltage of the DC bus.
