Abstract:

The EMS modular battery pack is a convenient and maintainable battery pack that encompasses several modules that are fixed to a rigid structure that carries the battery management system and each module contains several cells which are connected in series via welded leads and are supported mechanically within each module. The division of module facilitates the removal of non-functional cells within the module with ease and the battery pack also provides a battery management system that detects a non functional module using the sensing circuitry built in each module. The modular battery pack design facilitates various configurations of battery pack both electrically and mechanically since any number of modules can be combined to build a battery pack.
