The invention relates to a centralized modular battery framework which comprises a first battery module, a second battery module, a battery cut-off control unit and a battery management system; the capacity of the first battery module is half of that of the second battery module; the nominal voltage of the first battery module is twice of the nominal voltage of the second battery module; a preset number of first battery modules are connected in series to form a first high-voltage loop; two times of the preset number of the second battery modules are connected in series to form a second high-voltage loop; and the plurality of first high-voltage loops and/or the plurality of second high-voltage loops are connected in parallel with the battery cut-off control unit and the battery management system to form battery packs with different energies. The battery packs with different energy and different capacity configurations can be realized, the requirements of various vehicle models under a battery framework are met, the development cost and period are reduced, the battery packs can be suitable for all vehicle models under the framework only by developing two modules, and the cost and period caused by repeated development are greatly reduced.

    本发明涉及一种集中式模块化电池架构,包括第一电池模组、第二电池模组、电池切断控制单元及电池管理系统;所述第一电池模组的容量为第二电池模组的容量的一半;所述第一电池模组的标称电压为第二电池模组的标称电压的两倍;预设个数的所述第一电池模组串联形成第一高压回路;两倍预设个数的所述第二电池模组串联形成第二高压回路;若干个第一高压回路和/或若干个第二高压回路并联于电池切断控制单元及电池管理系统组成不同能量的电池包。可以实现不同能量及不同容量配置的电池包,满足电池架构下各种车型的需求,减少开发费用及周期,只需要开发两种模组,即可适用于架构下的所有车型,大大降低了重复开发而产生的费用和周期。
