BATTERY CONTAINMENT

摘要

A battery housing for lithium ion cells includes a plurality of cell modules, having a plurality of cells between a top conductive plate and a bottom conductive plate and attached to a conductive plate by tabs attached to similarly polarized ends of each of the cells in the module to define a parallel connection between all of the cells in the module. A battery housing stacks the modules to define a series connection between the charge plates, and electrically couples adjacent stacks with a common charge plate to define a series connection between each of the stacks. Charge logic for preventing excessive charging or discharging of the cells, and permits charge and discharge rates up to 6C. Tabs on each conductive plate provide a redundant connection to each circular face of the cells for resisting shock and vibration.
