The invention discloses a miniaturized energy storage charging system, which comprises an energy storage converter sharing a direct current bus, a battery module, a photovoltaic module and a charging pile console, the charging pile console is connected with a plurality of charging terminals; the energy storage converter is used for converting alternating-current electric energy on the public power grid into direct-current electric energy and transmitting the direct-current electric energy to the direct-current bus; the battery module is used for storing electric energy on the direct-current bus or transmitting the electric energy to the direct-current bus at a discharge rate greater than 1; the photovoltaic module is used for converting light energy into direct-current electric energy to be transmitted to the direct-current bus; and the charging pile console is used for providing the electric energy on the direct current bus for the charging terminal when the charging terminal has a charging demand, preferably meeting the charging demand of the over-charging terminal when the over-charging terminal is activated, and being compatible as a fast charging terminal when the over-charging terminal is not activated. According to the miniaturized energy storage charging system, under the condition that the capacity of a transformer of a public power grid does not need to be expanded, the electric vehicle can still be rapidly charged.
本发明公开了一种小型化储能充电系统,包括:共直流母线的储能变流器、电池模组、光伏模组和充电桩控制台;充电桩控制台连接多个充电终端;储能变流器用于将公共电网上的交流电能转化为直流电能输送给直流母线;电池模组用于存储直流母线上的电能或者以大于1的放电倍率向直流母线输送电能;光伏模组用于将光能转化为直流电能输送给直流母线;充电桩控制台用于在充电终端有充电需求时,将直流母线上的电能提供给充电终端,并且在超充终端被激活时,优先满足超充终端的充电需求,在超充终端未被激活时,超充终端兼容为快充终端。本发明的小型化储能充电系统,在无需对公共电网的变压器容量进行扩容的情况下,仍可对电动汽车实现快速充电。
