BATTERY MODULE WITH THERMAL RUNAWAY AND GAS EXHAUST MANAGEMENT SYSTEM

摘要

Apparatus, methods and systems are provided for thermal runaway and gas exhaust management for high power batteries. A battery module has a plurality of cell-containing carriers stacked on top of one another to form a cell stack having a front end and a rear end. A duct extends through the cell stack between the front end and the rear end for collecting escaped gases from the battery cells. A self-closing one-way pressure relief valve is located in the duct toward the rear end of the cell stack. The pressure relief valve connects to a piping system for carrying the gases to a remote location where the gases can be safely released and dispersed.
