The embodiment of the invention provides a DC-DC conversion device for a charging pile and the charging pile. The DC-DC conversion device for the charging pile comprises a group of power supply terminals, a plurality of groups of load terminals and a plurality of isolated DC-DC conversion circuits. Wherein the input end of each isolated DC-DC conversion circuit is connected with the group of power supply terminals, and the output ends of the plurality of isolated DC-DC conversion circuits are connected with the plurality of groups of load terminals in a one-to-one correspondence manner, so that the DC-DC conversion device for the charging pile forms a single-path input and multi-path independent output architecture. And furthermore, the DC-DC for the charging pile can realize wide-range power output, and also has relatively high power utilization rate. Thus, the charging pile can achieve the charging speed of one second and one kilometer, the charging experience of one cup of coffee and full electricity is brought to a user, waste of charging resources is avoided, and the operation benefits of the charging pile are improved.

    本申请实施例提供一种充电桩用直流转直流DC‑DC转换装置和充电桩。充电桩用DC‑DC转换装置包括一组电源端子、多组负载端子和多个隔离式DC‑DC转换电路。其中,每个隔离式DC‑DC转换电路的输入端连接该一组电源端子,多个隔离式DC‑DC转换电路的输出端与多组负载端子一一对应连接,以使充电桩用DC‑DC转换装置形成单路输入,多路独立输出的架构。进而,充电桩用DC‑DC能够在实现宽范围功率输出的同时,还具有较高的功率利用率。这既有利于使充电桩实现“一秒一公里”的充电速度,为用户带来“一杯咖啡,满电出发”的充电体验,也有利于避免充电资源浪费,提高充电桩的运行效益。
