VENT SHIELD FOR A BATTERY MODULE

摘要

The present disclosure relates generally to a battery module having a housing and a stack of battery cells disposed in the housing. Each battery cell has a battery cell terminal and a battery cell vent on an end of each battery cell, and the battery cell vent is configured to exhaust effluent into the housing. The battery module has a vent shield plate disposed in the housing and directly along an immediate vent path of the effluent, a first surface of the vent shield plate configured to direct the effluent to an opening between the shield plate and the housing, and a second surface of the vent shield plate opposite the first surface. The battery module also has a venting chamber coupled to the opening and at least partially defined by the second surface and a vent configured to direct the effluent out of the battery module.

主权项

1. A battery module, comprising:
a housing; a first stack of battery cells disposed in the housing, wherein each battery cell of the first stack of battery cells comprises a battery cell terminal and a battery cell vent, the battery cell terminal and the battery cell vent are on an end of each battery cell, and the battery cell vent is configured to exhaust battery cell effluent into the housing; a first vent shield plate disposed in the housing and directly along an immediate vent path of the battery cell effluent; a first surface of the first vent shield plate configured to direct the battery cell effluent to an opening between the first vent shield plate and the housing; a second surface of the first vent shield plate opposite the first surface; a venting chamber fluidly coupled to the opening and at least partially defined by the second surface; and a vent fluidly coupled to the venting chamber and configured to direct the battery cell effluent out of the battery module.
