BATTERY PACK MECHANICAL DESIGN TO ACCOMMODATE LEAD-ACID AND LITHIUM BATTERY WITH SAME PACKAGING

摘要

An electric vehicle has a housing that can interchangeably accommodate at least two different types of batteries therein. A plurality of modules are provided within the housing. Each module has a plurality of batteries of a first type arranged into a first battery module that is interchangeable with a plurality of batteries of a second, different type arranged into a second battery module. Both types can supply power to the electric vehicle. Because each the first and second battery modules have similar shape, the housing allows for a modular design, use of different types of batteries, and easy removal and replacement during assembly. A battery management system is also provided to monitor the modules.
