Abstract
A low voltage (LV) charging system for charging a high voltage (HV) rechargeable energy storage system (RESS), such as a HV RESS operable for electrically powering a traction motor of an electric vehicle. The LV charging system may include an input configured for receiving LV electrical power from a LV source and a distributed converter system configured for charging a plurality of modules of the HV RESS via a plurality of charging circuits. The charging circuits may be configured for separately charging one of the modules with a charging electrical power derived from converting the LV electrical power. The LV charging system may further include a controller configured for individually controlling the charging electrical power provided via each of the charging circuits.
