Abstract

A distributed battery module thermal management system, device and method for use in battery pack systems consisting of a plurality of multiple battery modules interconnected in series or parallel. One example of system is for forklift batteries operating in sub-zero applications. The system includes a battery pack master controller that manages each battery module thermally to optimize the cell temperatures. By doing so the system longevity and performance can be maximized. The system consists of a battery monitoring module that collects data from sensors such as thermistors, a housing designed for passive cooling with heaters to provide active heating applied to a module core consisting a plurality of cell blocks.
