The invention discloses a combined high-voltage charging energy storage circuit and a control system. A first energy input module, a second energy input module, a first DC/DC conversion module, a second DC/DC conversion module, a first energy storage battery, a second energy storage battery, a comprehensive control module, a first bypass protection circuit, a second bypass protection circuit, a first switch module and a second switch module are adopted. And the comprehensive control module is used for realizing coordinated control on the operation states of the first DC/DC conversion module and the second DC/DC conversion module according to the detection information and the interaction information of the battery management system, performing protective control on the first energy storage battery and the second energy storage battery, and performing on-off control on the first switch module and the second switch module. And load access control of the combined high-voltage charging energy storage circuit is completed. The energy storage capacity, the charging speed and other indexes are improved, and the defects of large power consumption, difficult turn-off, large switching impulse and the like caused by large current are overcome.
