Disclosed herein is a multi-cell battery pack having optimal temperature distribution throughout the battery pack and optimal air flow through the battery pack. Disclosed herein is a battery pack which provides optimal temperature distribution throughout the battery pack, wherein maximum cell temperature (T) and temperature differential amongst all cells in the battery pack (&#x394;T) are optimized for efficient thermal management providing safety, improved performance and extended life of the battery pack and electrochemical cells. Also disclosed herein is a battery pack which provides optimal flow through the battery pack and minimal pressure drop (&#x394;P) throughout the battery pack.

Battery pack

A battery assembly includes a housing and N charge storage devices within the housing. The system also includes a first tray includes a first side that includes X areas that transfer first current from electrolyte leaked from a first one of the N charge storage devices to a current detector. The tray includes a second side that insulates the housing from the electrolyte. N and X are integers greater than or equal to 1.

Isolation tray for a battery system

A thermal imaging system for a battery module enclosure that includes first and second battery module enclosure components between which a weld is formed includes a thermal imaging camera that focuses on the first and second battery module enclosure components within a predetermined amount of time after the weld is formed and that acquires a thermal signature. A control module includes an image processing module that receives the thermal signature and that locates a predetermined reference point in the thermal signature. An image comparison module receives the thermal signature and uses the predetermined reference point to compare the thermal signature to a template signature in order to verify structural integrity of the weld. The image comparison module computes a relative measure of deviation of the thermal signature from the template signature and identifies the weld as defective when the relative measure of deviation is greater than a predetermined value.
