The invention belongs to the technical field of electric vehicle charging piles, and discloses a charging pile short circuit detection circuit and a novel charging pile. When the charging pile short circuit detection circuit carries out short circuit detection, an external resistor is connected with the charging pile in series, and a charging pile plug is powered on; the current value and the voltage value of a circuit formed by the external resistor and the charging pile are measured through a multifunctional electric power meter, and if the calculated resistance value is the same as the resistance value of the external resistor, it is indicated that the charging pile is short-circuited; and if the calculated resistance value is greater than the resistance value of the external resistor, the charging pile is not short-circuited. According to the invention, the mode of measurement through a test pencil in the prior art is changed, and the measurement efficiency is improved.
本申请属于电动车充电桩技术领域,公开了一种充电桩短路检测电路及新型充电桩,其中,充电桩短路检测电路在进行短路检测时,将外加电阻与充电桩串联,给充电桩插头通电,采用多功能电力仪表测得由外加电阻和充电桩形成的电路的电流值以及电压值,若计算得出的电阻值与外加电阻的阻值相同,则说明充电桩发生短路;若计算得出的电阻值大于外加电阻的阻值,则说明充电桩未发生短路。本申请改变了传统技术中通过测电笔进行测量的方式,提高了测量效率。
