Systems and methods are provided to vent a battery pack system. The battery pack system comprises a first wall positioned in a first portion of a vehicle and a second wall positioned in a second portion of the vehicle. A first plurality of pressure release valves is embedded in the first wall, wherein the first plurality of pressure release valves is arranged release gas from between the first wall and another feature or component of the battery pack system. A second plurality of pressure release valves is embedded in the second wall, wherein the second plurality of pressure release valves are arranged to enable the egress of gas from between the second wall and another feature or component of the battery pack system.

Optimized battery assembly venting

Systems and methods are provided to vent a battery pack for an electric vehicle. The battery pack comprises a pack housing subdivided by a crossmember. The crossmember defines a multidirectional vent passage configured to allow venting with a first bay and a second bay. A pressure release valve is arranged on the pack housing and configured to release pressure based on the multidirectional vent passage.

Systems and methods are provided to vent a battery pack using a pressure release valve. The pressure release valve comprises a housing configured to be secured to an outer surface of a sidewall of a battery pack. A first membrane is arranged in a first side of the housing. A second membrane in a second side of the housing and adjacent to the first membrane.

Aspects of the disclosure relate to a service port for an electrical power supply such as a battery. The service port may be an integrated pressure equalization and electrical probe port. In one or more implementations, the service port may include a housing have an open bore within which an electrical header is disposed. A gap may be provided between the electrical header and the housing to allow airflow though the service port into and/or out of an internal chamber of the electrical power supply for pressure equalization of the internal chamber. In one or more implementations, a breather element may be disposed in a distal end of the housing of the service port.
