Described herein are battery modules comprising integrated module converters, electric-vehicle battery systems comprising such modules, and methods of operating thereof. An electric-vehicle battery system comprises a high-voltage battery pack and high-voltage contactors that controllably isolate the pack's high-voltage area from other areas in the vehicle. The pack comprises multiple battery modules with battery cells and a primary module converter constantly connected to these cells. Each module has a lower voltage than the entire pack. The power output from the primary module converters is used to operate a battery controller and to close/activate the contactors in response to the switch position (e.g., an ignition switch). The primary module converters can be either constantly activated or controllably activated in response to the switch moving into an activated position. For example, a secondary module converter, with a lower power rating, can be used for this primary module converter activation.
