The invention provides a charging system of a power battery. The charging system comprises the power battery, a charging power supply, a power supply side main positive relay, a power supply side main negative relay, a sampling circuit, a voltage detection module, a BMS charging management module, a negative charging relay and a fast charging relay, the power side main positive relay is connected with the anode of the charging power supply; the power side main negative relay is connected with the cathode of the charging power supply; the sampling circuit is connected in series with the power side main positive relay and the power side main negative relay; the voltage detection module is connected with the sampling circuit in parallel, the output voltage of the charging power supply is determined by detecting the sampling voltage of the sampling circuit, the BMS charging management module controls the charging process of the power battery according to the output voltage, and when the output voltage is larger than or equal to the preset voltage, the charging system of the power battery forbids charging. According to the charging system of the power battery, the adhesion phenomenon of the relay in the charging loop can be effectively avoided in the using process, and the safety of the charging process is improved.
