Disclosed are a battery system, a method of operating the same, a vehicle, and a stationary energy storage system. The battery system comprises a power supply and a battery management system, and the battery management system comprises a DC/DC converter and a system basic chip SBC. The DC/DC converter is electrically connected to the power supply to receive power from the power supply and is configured to output an output voltage. The SBC is electrically connected in series with the DC/DC converter to receive the output voltage from the DC/DC converter. A microcontroller is connected to the SBC to receive power from the SBC. The relay driver is configured to control at least one relay and is connected to an output node of the DC/DC converter to receive an output voltage from the DC/DC converter. The microcontroller is electrically connected to the relay driver and is configured to: control the DC/DC converter to increase the output voltage from a first voltage (V1) to a second voltage higher than the first voltage (V1) prior to switching the at least one relay; and controlling the relay driver to switch the at least one relay when the DC/DC converter outputs the second voltage.
