The invention relates to a low-voltage distribution circuit of an electric automobile, which comprises a power supply, a power supply main switch, an ignition switch and a charging pile, and the power supply main switch and the ignition switch are sequentially arranged on a power supply transmission line; a relay K1 is arranged on a power transmission line between the power supply main switch and the ignition switch; the ignition switch output circuit is connected with an ON-gear relay K2, and the charging pile charging circuit is provided with a charging relay K3; an ON gear output power supply is connected with a normally closed pin of the charging relay K3; the output end of the charging relay K3 is connected to a power transmission line between the power supply main switch and the relay K1; the power supply main switch power transmission line and the charging relay K3 power transmission line are connected with diodes. Safety risks caused by false triggering of the power supply main switch in the vehicle driving process can be effectively avoided, and meanwhile the storage battery is prevented from being lack of electricity without manual charge guarding.

    本发明涉及一种电动汽车低压配电电路,包括电源、电源总开关、点火开关和充电桩,所述电源总开关和点火开关依次设置于电源输电线上;在所述电源总开关和点火开关间输电线上设置有继电器K1;在所述点火开关输出电路上连接有ON档继电器K2,在所述充电桩充电电路上设置充电继电器K3;ON档输出电源与充电继电器K3常闭脚连接;所述充电继电器K3输出端连接于电源总开关和继电器K1间输电线上;所述电源总开关输电线上、充电继电器K3输电线上连接有二极管。本发明可有效避免车辆行驶中电源总开关误触发而带来的安全风险,同时无需人工看管充电以防止蓄电池亏电。
