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.

Abstract: A relay control system for a battery system is provided. The relay control system includes: an electrical interface configured to detachably receive a connector; a power supply electrically connected in parallel to a coil of a relay through power supply lines; a relay driver switch interconnected between the power supply and the coil in one of the power supply lines; and a controller electrically connected in parallel to the relay driver switch through relay driver control lines to control the relay driver switch. One of the power supply lines or the relay driver control lines is routed across the interface, and the relay control system is configured to open the relay when the one of the power supply lines or the relay driver control lines is interrupted in response to the connector being detached from the interface.
