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.
