This reference design implements a secondary thermal monitoring solution for large scale battery packs. Many industry guidelines require the secondary temperature system to remain powered and operational in the event that the primary power supply is lost. This design is capable of continuing operation in a low power state by utilizing low power, factory preset thermal trip points, on a super capacitor powered backup rail. The solution ensure that any over or under temperature event can be captured and dealt with even when the main system controller's power is unavailable, increasing the safe operating window of the total system.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
