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.

Optimized battery assembly venting

A high voltage distribution system is provided with multiple fuses. The high voltage distribution system includes multiple laminated busbars that are electrically coupled to a battery and to the multiple fuses. Busbars are electrically coupled to the one or more fuses via electrical connections between the busbars and the fuses. The electrical connections can pass through other busbars without having an electrical coupling to the other busbars. An insulating layer may be used between the busbars to prevent overcurrent events. The configuration, size, and position of each busbar is selected based on the electrical requirements of components that are electrically coupled to the busbar and based on the prevention of overcurrent events.

High voltage laminated power distribution system with integrated fuses

A battery module and a method of assembling the battery module are provided. The battery module includes a cooling surface having a first area and a second area with different cooling capacities, an adhesive including a first component having a first thermal conductivity and a second component having a second thermal conductivity, and a first battery and a second battery. The first battery is secured to the first area by a first portion of the adhesive and the second battery is secured to the second area by a second portion the adhesive. The first portion of the adhesive has a first ratio of the first component to the second component and the second portion of the adhesive has a second ratio of the first component to the second component. The first and second ratios are different and compensate for the different cooling capacities of the first and second areas.

Temperature gradient control with thermal interface material variation

A battery enclosure is provided having unswitched positive and negative terminals that are physically separated. The unswitched positive and negative terminals may be connected to circuit protection components, such as contactors and fuses. The contactors are set to an opened or closed state via a contactor control module. The battery enclosure includes external terminals that electrically couple the battery and circuit protection devices to external components, such as charging ports and electrical loads.

Distribution system for unswitched high voltage power

Aspects of the disclosure relate to a configurable battery pack. The configurable battery pack may include an enclosure that is formed from housing structures that can be selectively chosen to form an enclosure of various sizes, for enclosing various numbers of battery modules and/or battery cells.

Configurable battery pack

An electrically conductive member can include a first opening and a second opening. The first opening of the electrically conductive member can engage a first member of a cell carrier to at least partially align the electrically conductive member with the cell carrier. The second opening of the electrically conductive member can engage with a second member of the cell carrier for coupling the electrically conductive member with the cell carrier.

Electrically conductive apparatus

A drain system is described for allowing fluid to drain from a battery pack while maintaining structural integrity of the battery pack. A frame of the battery pack is comprised of several retaining members in which valves are disposed to allow fluid to exit the battery pack. The valves are positioned such that forces normally experienced while driving a vehicle, such as acceleration, deceleration, and turning forces, cause the fluid to flow toward and through the valves.

Battery pack water drain system

A battery pack can include a bay having a first bay wall and a second bay wall. The battery pack can include a battery cell having a top portion and a bottom portion. The top portion of the battery cell can face the first bay wall of the bay and the bottom portion of the battery cell can face a second bay wall of the bay.

Battery pack

A battery system for providing electric power to a vehicle includes an assembly having battery cells. The battery system also includes a shear wall that is arranged along a lateral side of the assembly to provide structural support. The shear wall is two-part, including a first element and a second element, both of which may be formed from sheet metal and welded together. The first element has a first flange extending away from the lateral side of the assembly, and the second element has a second flange. The first flange and the second flange are layered together to form an interface. The flanges are welded together at the interface, proximal to the assembly, to form a resulting flange that is thicker than either individual flange and that may be mounted to a frame member. The battery system may also include another shear wall on the opposite lateral side.

Multi-part battery module wall

A battery system of a vehicle may include a main battery pack, a secondary battery pack, and one or more secondary contactors. The main battery pack is integrated into the vehicle and includes a first plurality of battery cells, a first DC bus coupled to the first plurality of battery cells, and main contactors coupled to the first DC bus to form a switched DC bus. The secondary battery pack includes a second plurality of battery cells, and a second DC bus coupled to the second plurality of battery cells. The second DC bus of the secondary battery pack is electrically coupled to the switched DC bus of the main battery pack via the secondary contactors. In some embodiments, the main battery pack includes control circuitry configured to communicate with control circuitry of the secondary battery pack to manage or monitor coupling of the battery packs.

Auxiliary energy system architecture

Electric vehicle battery packs with external side enclosures for containing electrical connectors and other components therein. Each enclosure is sized to support various connectors or other components as desired, and may have a number of openings formed to provide interfaces for connecting various electric vehicle systems to the battery pack. The enclosures may be placed at various locations along one or more sides of the battery pack, and connectors may be routed over an upper surface of a battery pack frame or through a gap formed between the pack frame and cover. Enclosures may be made of any material, including plastic for lower weight applications and metal for improved electromagnetic interference shielding.
