The invention relates to the technical field of energy storage vehicle charging, and discloses an energy storage type intermittent vehicle power supply system which comprises a transformer, a rectifier, a first DC/DC module, an energy storage device, a second DC/DC module, a plurality of isolation switches and power supply rails correspondingly connected with the isolation switches. The first DC/DC module is used for charging the energy storage device through preset low power when the vehicle does not enter a station; and the second DC/DC module is used for outputting electric energy to the to-be-charged vehicle when the to-be-charged vehicle enters the station. In the invention, a capacity of the energy storage type vehicle charging system connected to the power supply system is effectively reduced, and expenditure cost of a capacity electricity price is decreased for users; the capacity of the transformer can be reduced, and a loss during no load is decreased; in addition, the systemcan adopt AC380V to charge the vehicle, and a problem that a special power supply line needs to be erected in some scenes is solved; and finally, the energy storage device in the power supply systemreduces dependence on a power supply network when the vehicle is charged.

    本发明涉及储能车辆充电技术领域,公开了一种储能式间歇性车辆供电系统,本系统包括:变压器、整流器、第一DC/DC模块、储能装置、第二DC/DC模块、多个隔离开关以及和隔离开关对应连接的供电轨;第一DC/DC模块,用于车辆未进站时,通过预设小功率对储能装置进行充电;第二DC/DC模块,用于待充电车辆进站时,输出电能至待充电车辆。本发明,有效降低了储能式车辆充电系统接入供电系统的容量,为用户减少了容量电价的支出成本;还能减小变压器容量,降低了空载时的损耗;并且本系统可采用AC380V对车辆充电,解决部分场景最后需要架设供电专线的问题,最后,本供电系统中的储能装置降低了车辆充电时对供电网络的依赖。
