  • LIFE-EXTENDING RECHARGE CONTROL FOR COLD WEATHER LITHIUM-ION POWER SUPPLIES
    Publication number: 20220209320
    Abstract: A lithium-ion battery assembly configured to provide electric power to a vehicle. The battery assembly includes a plurality of battery cells interconnected to provide a combined electrical potential between positive and negative terminals of the battery assembly, and a printed circuit board assembly (PCBA) disposed adjacent to a first array of battery cells of the plurality of battery cells. The PCBA includes a collector plate electrically coupled with the first array of battery cells, a temperature sensor configured to obtain temperature readings, a plurality of heaters configured to generate heat using electrical power, and an assembly processor. The assembly processor is configured to obtain readings from the temperature sensor, determine an estimated battery cell temperature, and initiate a heating program by delivering electrical power to the plurality of heaters from an electrical power source when the estimated battery cell temperature is below a threshold.
