Zusammenfassung:	A vehicle and a system performing a method of heating a battery of the vehicle. The vehicle includes a battery having a first cell having a first cell type and a second cell having a second cell type, a DC/DC converter having a first side and a second side, and a processor that controls flow of current. The first cell is connected to a first side of a DC/DC converter and the second cell is connected to the second side of the DC/DC converter. A first current is flowed between the first cell and the second through the DC/DC converter to heat the first cell and the second cell during a first heating phase. A second current is flowed between the second cell and the DC/DC converter to heat the second cell during a second heating phase.
