Abstract: An electrical battery exchanging system for reuse application is disclosed. The system includes: a number of rechargeable battery packs, a battery condition detecting module, a user ID checking module, a power source, a charging controlling module. Since the system can monitor conditions of rechargeable battery cells of the rechargeable battery packs and uses user ID for operating control purpose, it has benefits of conveniently exchanging low-power battery with fully charged one, easily sorting out end-of-life batteries and getting them for recycle or reuse, simply charging service fee and stably operating under a business model.

Abstract: A system for uniformly distributing temperature across battery units is disclosed. The system includes: a heat conducting fluid, enclosing the battery units and being capable of substantially circulating around the battery units and/or along a specified path among the battery units; a closed housing, enclosing the battery units and the heat conducting fluid; and a circulating module, installed inside or out of the closed housing, for driving the heat conducting fluid to circulate around the battery units and/or along the specified path. When the circulating module drives the heat conducting fluid to circulate, temperature across the battery units is substantially uniformly distributed.
