A traction battery assembly is provided including a support member, two battery cells, a busbar, and a segmented busbar holder. The battery cells include adjacent terminals at differing heights relative to the support member. The busbar is attached to the terminals. The segmented busbar holder includes adjacent panels configured to cover and orient the busbar relative to the terminals. The panels are also configured to move relative to one another such that the holder accommodates the differing heights of the terminals.

Flexible busbar holder for welded cells

A traction battery thermal plate assembly may include a structure having edge portions defining a cavity and configured to support a battery cell array, a thermal plate disposed within the cavity and adjacent to the array, and a spring assembly disposed within the cavity between the structure and the plate. The spring assembly may be configured to exert a force against the plate such that plate contacts the array to transfer heat between the array and the plate. The thermal plate disposed within the cavity may be below the array. The spring assembly may include a body defining a plurality of tabs configured to extend outward from a plane defined by the body. The spring assembly may include a base portion and an upper portion configured to support one or more compression springs therebetween.

A cooling system may be operable to cool a battery pack or other device through a heat exchange operation supported, at least in part, with cycling of a coolant relative to a coldplate or other thermally conducting surface of the device and/or attached thereto. The system may include a coldplate operable to exchange heat with a battery pack; and a coolant tank operable to exchange heat with the coldplate, the tank having a channel for directing a coolant flow in a direction from an inlet of the tank to at least one outlet of the tank and an inlet accumulator between the inlet and a beginning of the channel, wherein the inlet accumulator is wider along the coolant flow direction than the channel and the inlet and having a sloped side leading towards the channel configured to pool the coolant flow prior to entry into the channel.

Battery pack liquid channel and coldplate cooling system

A battery pack for a vehicle may include a cell array defining an upper surface and a housing defining a raised portion extending along and above a length of the array such that the raised portion and upper surface define a vent manifold therebetween which may be configured to collect gases generated by the array. The housing may define a discharge opening configured to allow gases to exit the manifold. A pair of end plates may be disposed at opposing ends of the array. One of the end plates may define a pass through portion in at least partial registration with the discharge opening. An outlet tube may be configured to facilitate fluid communication between the vent manifold and exterior of the vehicle. The battery pack may also include spacers located between upper edges of adjacent cells and may be configured to prevent cooling gases from entering the vent manifold.

Battery pack

The present disclosure relates to a vehicle battery pack having battery cells with an integral control circuit configured to communicate with a battery energy control module.

Vehicle battery cell with integral control circuit

A power source is electrically connected with a battery and an electrical load. The power source has an output voltage and provides current for the battery and electrical load. A charging voltage for the battery is determined based on temperature of the battery. An offset voltage is determined based on the provided current to the battery. The output voltage is determined based on the charging and offset voltages.

Automotive voltage compensation system and method

A battery module assembly and method of assembling a battery. The battery module assembly includes a plurality of modules in which a plurality of battery cells are preassembled. The modules are compressed by end plates that are held together under compression by a plurality of linking members. The end plates may include a protrusion that applies pressure to the central portion of the battery cells within the modules. The central portion of the end plates may be partially spherical, partially cylindrical or a flat surface.

Method and apparatus for manufacturing a battery for a vehicle

A system and method is provided for balancing a storage battery for an automotive vehicle. The battery is of the type including a plurality of storage cells. The system includes a thermoelectric device and a controller. The thermoelectric device receives thermal energy and converts the thermal energy into electric energy. The controller determines a subset of the storage cells in the battery to be charged based on an amount of electric charge in each of the storage cells. Furthermore, the controller causes the electric energy to be distributed to each storage cell in the subset in an effort to balance the battery in the vehicle.
