[0023] Specifically, the sensor at least includes a multimeter and a temperature sensor connected with the battery, the sensor is used for measuring the voltage, temperature, current and internal impedance and other key parameters of the battery, and a unified data collection module is arranged for collecting the data of voltage, temperature, current and internal impedance as the normal parameter, the sensor collects the normal parameter once per second and uploads the normal parameter to the data processing unit;

[0024] After receiving the data each time, the data processing unit compares a plurality of data in the normal parameter with the standard range to judge whether there is a fault, and uploads the judgment result to the user terminal 1;

[0025] The user terminal 1 at least includes a display screen and an input interface, the operating personnel views the received judgment result through the user terminal 1, and then views whether the battery has a fault, and simultaneously, when the user terminal 1 receives the judgment result of existing fault, an alarm is sent, and the monitoring of the battery is completed;

[0027] In the above process, the battery in the discharge state and the power-off state has a probability to show different properties, for example, when the external device is short-circuited, the current supplied by the battery to the external device is different from the normal current of the battery, and the external device short-circuiting also has a probability to cause damage to the battery, and in the above scheme, the inspection process is relatively simple and cannot detect the battery in the two states, and the detection result is not accurate enough, therefore, the switch and the measuring resistor are further included, the measuring resistor is connected with the battery through the switch, and the sensor is electrically connected with the switch, and the sensor is used to connect the switch and detect the reference parameters of the battery after the battery is powered off.

[0028] Specifically, the sensor is provided with an OR gate circuit, and the OR gate circuit controls the on-off of the switch, and the OR gate circuit instructs the switch to be closed when the battery is connected with the external device, and instructs the switch to be opened when the battery is disconnected with the external device, at this time, the battery is disconnected with the measuring resistor when supplying power to the outside, and is connected with the measuring resistor when not supplying power to the outside;
