A battery system (10) is disclosed comprising a power source (20) and a battery management system (30) including a DC/DC converter (32) and a system basis chip, SBC (40). The DC/DC converter (32) is electrically connected to the power source (20) to receive power from the power source (20) and configured to output an output voltage. The SBC (40) is electrically connected in series with the DC/DC converter (32) to receive the output voltage from the DC/DC converter (32). A microcontroller (50) is connected to the SBC (40) to receive power from the SBC (40). A relay driver (60) is configured to control at least one relay (62, 64), wherein the relay driver (60) is connected to an output node (34) of the DC/DC converter (32) which is interconnected between the SBC (40) and the DC/DC converter (32) to receive the output voltage from the DC/DC converter (32). The microcontroller (50) is electrically connected to the relay driver (60) and configured to: before switching the at least one relay (62, 64), control the DC/DC converter (32) to increase the output voltage from a first voltage (V1) to a second voltage (V2) higher than the first voltage (V1); and control the relay driver (60) to switch the at least one relay (62, 64) while the second voltage is outputted by the DC/DC converter (32).
