摘要： A method of controlling a thermal runaway event in a battery system having first and second battery modules. The method includes detecting a thermal runaway event in the first battery module, and, in response to the detection of the thermal runaway event, determining whether an electrical current is flowing through the first battery module. The method also includes electrically decoupling the first battery module from the second battery module in response to the detection of the thermal runaway event, if the current is not flowing through the first battery module. Furthermore, the method includes electrically connecting the second battery module to an electrical load to discharge the second module through the load, if the current is determined to be flowing through the first battery module or after decoupling the first module. Discharging the second battery module is intended to control propagation of the thermal runaway event through the second module.

摘要： A thermal management system for a rechargeable battery pack assembly includes a conduit having an upstream end and a downstream end, the downstream end operatively connectable to an enclosure of the rechargeable battery pack assembly at a port of the rechargeable battery pack assembly. A sealing mechanism is configured to transition from a first state in which the sealing mechanism blocks flow of an applied stream of water through the conduit from the upstream end through the port, to a second state in which the sealing mechanism permits flow from the upstream end to the port and through the port into the interior cavity to cool the interior cavity.

摘要： A system for an electrified vehicle includes a rechargeable energy storage device (RESS) electrically couplable via an electric power bus to a high-voltage actuator, a telematics system, and an on-vehicle controller. The on-vehicle controller includes an instruction set that is executable to: receive, via the telematics system, a notification of a proximal impending catastrophic event; determine an intent to safeguard the electrified vehicle; execute a high-voltage discharge protocol in response to the intent to safeguard the electrified vehicle, wherein the high-voltage discharge protocol includes operating the high-voltage actuator; monitor a state of charge (SOC) of the RESS; and electrically decouple the RESS from the electric power bus when the SOC of the RESS is less than a first threshold SOC.
