The invention discloses a super capacitor and storage battery hybrid power system and a charging control method and belongs to the technical field of hybrid power systems. The system comprises a super capacitor array, a storage battery array, a parallel charging and discharging DC/DC converter, a super capacitor parallel bus and a storage battery parallel bus. The charging control method comprises a storage battery serial charging control method and a super capacitor parallel charging control method. According to the system, sudden power is provided by the super capacitor, and the storage battery mainly supplements power output of the super capacitor through constant-current discharge, so capacity attenuation of the storage battery caused by the sudden power is avoided, and the service life of the storage battery is prolonged.

    本发明公开了一种超级电容和蓄电池混合动力系统及充电控制方法,属于混合动力系统技术领域。本发明系统包括:超级电容阵列、蓄电池阵列、并行充放电DC/DC变换器、超级电容并行母线和蓄电池并行母线,其充电控制方法包括:蓄电池串行充电控制方法和超级电容并行充电控制方法。本发明由超级电容提供突发性功率,蓄电池主要以恒流放电补充超级电容的功率输出,避免突发性功率造成蓄电池容量衰减,延长蓄电池的使用寿命。
