The invention discloses a method for realizing a hybrid power storage battery by using a conventional storage battery and a capacitor, belongs to the field of storage batteries, relates to a chemical energy storage storage battery and the application field thereof, and is suitable for a use scene that the storage battery needs to provide continuous lower power and instantaneous high power. According to the invention, the one-way functional part is additionally arranged between the conventional storage battery and the capacitor, so that the voltage of the capacitor is not lower than that of the storage battery, the capacitor does not lose electric quantity due to the stop of an external charging power supply, and the capacitor can release electric energy prior to the storage battery when an instantaneous high-power discharge demand exists. The electric energy is preferentially released through the capacitor, and the instantaneous high-power discharge probability or/and discharge intensity of the storage battery is eliminated or reduced, so that the service life of the storage battery is prolonged, the reliability of an electric power storage system is improved, the requirement of the application scene on the performance of the storage battery is reduced, and the electric power storage cost is possibly reduced.
本发明公开了一种用常规蓄电池和电容实现混合动力蓄电池的方法,这种方法属于蓄电池领域,涉及化学储能的蓄电池及其应用领域,适用于蓄电池既需要提供持续较小功率,又需要提供瞬时大功率的使用场景。本发明通过在常规蓄电池和电容之间加装单向功能部件,使电容的电压不低于蓄电池的电压,且电容不会因为外部充电电源的停止而失去电量,当有瞬时大功率放电需求时,电容能优先于蓄电池释放电能。通过电容优先释放电能,消除或减少了蓄电池的瞬时大功率放电机率或/和放电强度,从而延长蓄电池的寿命,提高蓄电系统的可靠性,降低了此类应用场景对蓄电池性能的要求,使减少蓄电成本成为可能。
