The invention discloses a charging pile safety protection method and system and a cloud server. The charging pile safety protection method comprises the steps that the charging temperature detected by a charging pile is received; when the charging temperature is within the preset temperature interval, the total charging duration and the high-temperature charging duration in the charging process are obtained, and the high-temperature charging duration is the total duration when the charging temperature is within the preset temperature interval; determining a charging damage value of the charging pile in a single charging process according to the total charging duration and the high-temperature charging duration; and when the charging damage value is greater than a first preset value, sending a power-off control signal to the charging pile to control the charging pile to be powered off. According to the charging pile safety protection method, the temperature coefficient is considered from the time dimension, the charging damage value is calculated according to the high-temperature charging duration when the charging temperature is within the preset temperature interval and the total charging duration, the charging risk is recognized through the charging damage value, and the charging pile is controlled to be powered off in time when the charging risk is recognized. And the charging safety coefficient is improved.
本发明公开了一种充电桩安全防护方法、系统和云服务器。其中,充电桩安全防护方法包括:接收充电桩检测的充电温度;当充电温度处于预设温度区间时,获取充电过程中的充电总时长和高温充电时长,其中,高温充电时长为充电温度处于预设温度区间内的总时长;根据充电总时长和高温充电时长确定单次充电过程中充电桩的充电损伤值;在充电损伤值大于第一预设值时,发送断电控制信号至充电桩,以控制充电桩断电。上述充电桩安全防护方法从时间维度上考虑了温度系数,根据充电温度处于预设温度区间的高温充电时长和充电总时长计算充电损伤值值,通过充电损伤值识别充电风险,并在识别出充电风险时及时控制充电桩断电,以提高充电安全系数。
