The invention relates to a battery power system having a switchable architecture with thermal runaway protection. A rechargeable energy storage system (RESS) includes a battery controller and battery modules, each respective module having a battery cell, a cell sensing plate, and a semiconductor switch. The switch is connected in parallel with a battery cell within a respective module and is configured to conduct current during a thermal runaway propagation (TRP) event in which one or more cells are in an open state. The action bypasses the module and causes the electrical component to be powered by the RESS during the TRP event. A battery power system includes a direct current ("DC") voltage bus, electrical components connected thereto, a battery controller, and a RESS. A method for constructing a RESS includes connecting a respective semiconductor switch in parallel with at least one battery cell of each respective battery module of the plurality of battery modules, and electrically connecting the plurality of battery modules together to construct a RESS.

    本发明涉及一种具有带热失控保护的可切换架构的电池电力系统。可充电能量存储系统(RESS)包括电池控制器和电池模块,每个相应的模块具有电池单元、单元感测板和半导体开关。该开关与相应模块内的电池单元并联连接,并且被配置成在一个或多个单元处于开路状态的热失控传播(TRP)事件期间传导电流。该动作旁路该模块,并且使得电气部件在TRP事件期间由RESS供电。电池电力系统包括直流(“DC”)电压总线、连接到其上的电气部件、电池控制器和RESS。一种用于构造RESS的方法包括将相应的半导体开关与所述多个电池模块中的每个相应电池模块的至少一个电池单元并联连接,并且将所述多个电池模块电连接在一起以构造RESS。
