Abstract

To provide a modular rechargeable battery system allowing replacement work of batteries in a fork lift to be performed safely.SOLUTION: Many embodiments involve rechargeable battery assemblies that are forklift-battery-sized but that comprise multiple removable battery modules 200. The battery modules are individually rechargeable and are interchangeable with each other. A housing 100 contains six battery modules installed vertically on the front side of the assembly, and their electrical and data connections occur within the housing on the rear side. Assemblies are two sided so that a system has two racks with six modules per rack. Each battery module has an integrated battery supervisor system (BSS). A battery operating system supervisor (BOSS) module processor serves as a battery management system for the all the battery modules.SELECTED DRAWING: Figure 1
