Abstract: A battery system includes: a battery submodule including a plurality of secondary battery cells electrically connected to each other in series or in parallel; a battery module including a plurality of the battery submodules connected to each other in series or in parallel; and a crossbeam including a coolant duct. The battery module is mechanically coupled to the crossbeam, and the crossbeam is in thermal contact with a first side surface of at least one of the battery submodules of the battery module.

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.

Abstract: An electric-vehicle battery system includes a high voltage system with a plurality of connected rechargeable battery cells; a low voltage system with an operating voltage lower than an operating voltage of the high voltage system, the low voltage system supplying a battery system manager; and a real time clock configured to provide a system time to the battery system manager. The real time clock may be at least temporarily powered by the high voltage system.
