A battery module (140) comprises charging terminals (503, 504) for connecting the battery module (140) to a power source (505), a battery cell arrangement (210), and a DC-to-DC converter (510). A first terminal (501) of the battery cell arrangement (210) is connected to a first charging terminal (503). An input terminal (511) of the DC-DC converter (510) is connected to the second terminal (502) of the battery cell arrangement (210) and another input terminal (512) of the DC-DC converter (510) is connected to the second charging terminal (504). An output terminal (513) of the DC-DC converter (510) is connected to the first terminal (501) of the battery cell arrangement (210). The DC-DC converter (510) converts an input voltage (U3) received at its input terminals (511, 512) to an output voltage (U2) at the output terminal (513) of the DC-DC converter (510). The output voltage (U2) is higher than the input voltage (U3). The battery module (140)may for example be employed as a backup power source in a mobile co
