Abstract
A method for heating a battery in a vehicle comprises: setting, by a control unit, an alternating current (AC) storage device to a first operation mode; charging the AC storage device by transferring energy stored in the battery to the AC storage device; determining whether a charging level of the AC storage device corresponds to a defined upper threshold, setting the AC storage device to a second operation mode, when the charging level of the AC storage device is determined to correspond to the defined upper threshold, discharging the AC storage device by transferring energy stored in the AC storage device to the battery, determining whether a charging level of the AC storage device corresponds to a defined lower threshold, and setting the AC storage device to the first operation mode, when the charging level of the AC storage device is determined to correspond to the defined lower threshold.
