The disclosure proposes a battery heating method and a battery heating system 100 for a vehicle battery. The battery heating system comprise a vehicle battery 110, an auxiliary energy storage device 130, a direct current to direct current, DC-DC, converter 120 and a processing circuitry 102. The processing circuitry 102 is configured to cause the battery heating system 100 to operate in a first mode wherein the direct current to direct current, DC-DC, converter 120 is configured to control a current i to flow through the vehicle battery 110 in a first direction and operate in a second mode wherein the direct current to direct current, DC-DC, converter 120 is configured to control a current i to flow through the vehicle battery 110 in a second direction.
