The invention discloses a water-cooling multi-voltage multi-module direct-current bus charging energy storage system, which comprises a multi-voltage transformation and rectification system, a direct-current bus, a charging pile and a battery pack, and is characterized in that the multi-voltage transformation and rectification system comprises a high-voltage cabinet module, a multi-voltage output transformer, a low-voltage cabinet module, a capacitor cabinet module and a rectification cabinet module; according to the system, the power of the multi-voltage output transformer and the power of the rectifier cabinet modules are fully utilized, current is collected through the direct-current bus, charging current is provided according to needs, the charging output power of each charging pile is improved to the maximum extent, the rectifier cabinet modules are standby for each other, and the charging efficiency is improved. The reliability of the charging system is improved, a plurality of groups of rectifier cabinet modules are arranged, the redundancy is improved, the reliability can be improved by increasing the redundant rectifier power through the redundant rectifier cabinet modules, the influence on all the charging output loops due to the failure of a single rectifier cabinet module is only that the power of each output loop is reduced by 1/N, and the charging system can be normally charged and used.

    本发明公开了一种水冷多电压多模组直流母线充电储能系统,包括多电压变压整流系统、直流母线、充电桩、电池组,多电压变压整流系统包括高压柜模组、多电压输出变压器、低压柜模组、电容柜模组、整流柜模组;多电压输出变压器和整流柜模组并行接入直流母线,本系统充分利用多电压输出变压器和整流柜模组的功率,通过直流母线汇集电流,随需提供充电电流,最大限度提高每个充电桩的充电输出的功率,整流柜模组互为备用,提高充电系统的可靠性,整流柜模组设置多组,提高冗余量,可以通过冗余的整流柜模组增加冗余整流功率来提高可靠性,单个整流柜模组故障,对全部充电输出回路的影响只是每个输出回路的功率减少1/N,可以正常充电使用。
