Abstract: A system for preventing thermal runaway among battery modules utilized to power equipment. The system may also be utilized to prevent thermal runaway within a battery module among battery cells on an intra-modular basis. The system is beneficial for equipment with an occupant space for accommodating an operator of the equipment. Thermal runaway may be avoided by the active use of a flow control device directed at a housing space containing a battery module that may be prone to failure. Specifically, air may be driven into the housing or drawn from the housing during the emergence of an unintended energy release from the battery module so as to prevent the thermal runaway. Further, directing the energy release away from the battery module includes routing the energy release away from other modules and the occupant space.
