Abstract: A vehicle having an ambient temperature sensor, a low voltage lithium-ion battery and a controller is provided. The controller is configured to monitor the ambient temperature sensor and based on a determination that an ambient temperature is below a threshold value, provide an alternating current power to the low voltage lithium-ion battery. The alternating current power causes the low voltage lithium-ion battery to heat.
