20150084594 | BATTERY POWER SYSTEM HAVING HIGH WORKING STABILITY - A battery power system includes a number of battery modules. Each battery module includes a number of battery cells, a management circuit positioned at a first side of the battery module, and a heat source positioned at a second side of the battery module and opposite to the first side. The management circuit is electrically connected to and manages charging and discharging of the cells of the corresponding battery module. The heat source is thermally coupled to the cells of the corresponding battery module and dissipates heat generated by the cells of the corresponding battery module. The battery modules are arranged in two lines, and the first sides of the battery modules in one line are positioned adjacent to and face the first sides of the battery modules in another line. | 03-26-2015 |
