Abstract
A battery system includes: a battery management system comprising a DC/DC converter and a system basis chip; a microcontroller connected to the system basis chip to receive power from the system basis chip; and a relay driver configured to control a relay. The DC/DC converter receives power from a power source, and the system basis chip receives an output voltage from the DC/DC converter. The relay driver is connected to a node between the system basis chip and the DC/DC converter to receive the output voltage from the DC/DC converter. The microcontroller is electrically connected to the relay driver and is configured to: before switching the relay, control the DC/DC converter to increase the output voltage from a first voltage to a higher second voltage; and control the relay driver to switch the relay while the DC/DC converter outputs the second voltage.
