An electric automobile power battery high-voltage loop comprises a battery management system BMS, a power battery, a main drive interface, a high-voltage discharge interface and a charge interface, the positive electrode of the power battery is electrically connected with the positive electrode end of the main drive interface after sequentially passing through a pre-charge resistor and a pre-charge relay, and the positive electrode of the power battery is electrically connected with the positive electrode end of the main drive interface after passing through the main drive relay. The positiveelectrode of the power battery is electrically connected with the positive electrode end of the high-voltage discharge interface, the positive electrode of the power battery is electrically connectedwith the positive electrode end of the charge interface through the charge relay, and the negative electrode of the power battery is electrically connected with the main drive interface, the high-voltage discharge interface and the negative electrode end of the charge interface sequentially through the current sensor and the main negative relay. The battery management system BMS is in signal connection with the pre-charging relay, the main drive relay, the current sensor, the main negative relay and the charging relay. According to the design, the production cost is reduced on the basis of ensuring the product performance and functions.
