The invention provides a high-power charging cooling device and a charging cooling method. The high-power charging cooling device comprises an expansion kettle, a liquid outlet pipeline, a liquid return pipeline, a circulating pump and a heat dissipation mechanism, the expansion pot is used for accommodating a cooling medium; a first end of the liquid outlet pipeline is communicated with a liquid outlet of the expansion kettle, and a second end of the liquid outlet pipeline is communicated with a liquid inlet of the charging gun cable cooling pipe so as to convey a cooling medium to the charging gun cable cooling pipe; a first end of the liquid return pipeline is communicated with a liquid return port of the expansion kettle, and a second end of the liquid return pipeline is communicated with a liquid outlet of the charging gun cable cooling pipe so as to return the cooling medium after cooling and heat exchange to the expansion kettle; the circulating pump is arranged on a liquid outlet of the expansion kettle; the heat dissipation mechanism is arranged on the liquid return pipeline and used for conducting heat dissipation on the cooling medium returning to the expansion kettle. The problems that in the prior art, when a charging connection system carries out high-power charging, heat generated by a cable is too large, so that charging efficiency becomes low, a charging device is damaged, and safety accidents are caused are solved.

    本发明提供了一种大功率充电冷却装置及充电冷却方法,大功率充电冷却装置包括膨胀壶、出液管路、回液管路、循环泵以及散热机构;膨胀壶用于容纳冷却介质;出液管路的第一端与膨胀壶的出液口相互连通,第二端与充电枪线缆冷却管的进液口相连通以将冷却介质输送至充电枪线缆冷却管;回液管路的第一端与膨胀壶的回液口相互连通,第二端与充电枪线缆冷却管的出液口相互连通以将冷却换热后的冷却介质返回至膨胀壶;循环泵设置在膨胀壶的出液口上;散热机构设置在回液管路上,用于对返回膨胀壶的冷却介质进行散热。解决了现有技术中充电连接系统进行大功率充电时线缆产生的热量过大导致充电效率变低、损害充电装置以及引起安全事故的问题。
