Abstract:
A rechargeable energy storage system, includes a housing. A plurality of battery cells are disposed in the housing. A discharge vent passage is in communication with the housing, the discharge vent passage including a one-way valve and a nozzle. A chamber is in communication with the nozzle and including an air inlet passage with a one-way valve. An outlet pipe is connected to the chamber. According to an aspect, the air inlet passage of the thermal vent management system is arranged as a Venturi opening adjacent to the nozzle.
