According to the type and the model of the storage battery, the device can adopt an intelligent multi-mode charging control method in different charging stages of the battery, so that the actual charging process is always close to or equal to the optimal charging curve of the storage battery. The processor unit 81 selects a normal or emergency charging mode according to the battery state and outputs a charging instruction, the charging instruction is output to the high-power MOS tube 51 through the optical coupling array unit 52 of the isolation driving module 5 to enable the high-power MOS tube 51 to obtain a gate source voltage for conducting, the processed signal is used as the input of the D/A conversion unit 21 of the charging control module 2, the analog signals of the voltage and the current obtained after conversion are adjusted through the PID adjusting unit 22, the high-frequency inversion unit 14 of the charging power supply module 1 is driven through the driving control unit 23, and charging in different modes is realized by changing the inversion frequency and the duty ratio in real time; the power supply switching unit 11 selects alternating current or direct current input, the EMI filtering unit is used for improving the performance of an input power supply, if the input power supply is alternating current input, the alternating current input is converted into direct current through the AC/DC conversion unit 13 to be used as the input of the high-frequency inversion unit 14, and if the input power supply is direct current input, the direct current input is subjected to voltage stabilization and then is directly input into the high-frequency inversion unit 14; the high-frequency alternating current with controllable frequency is obtained into high-voltage high-frequency alternating current through the high-frequency transformer 15, the high-voltage high-frequency alternating current is input into the protection module 6 of the storage battery through the rectifying/filtering unit 16, and the charging current is provided for the storage battery through the temperature protection unit 61, the overcurrent protection unit 62, the overvoltage protection unit 63, the reverse connection protection unit 64 and the short-circuit protection unit 65.

2. And (3) detection function: the detection function of the storage battery is mainly used for detecting the state and the capacity of the storage battery.
The state detection of the storage battery mainly realizes the collection of state information of the storage battery in the charging and discharging processes of the storage battery, including the voltage, the current and the temperature information of the storage battery. The current acquisition unit 41, the voltage acquisition unit 42 and the temperature acquisition unit 43 respectively acquire current information, voltage information and temperature information of the storage battery, and the acquired current information, voltage information and temperature information enter the optical coupling array unit 52 in the isolation driving module 5 after being filtered by the filtering unit 71, amplified by the amplifying unit 72 and subjected to a/D conversion by the a/D conversion unit, so that electrical isolation is realized, and then the current information, voltage information and temperature information are sent to the processor unit 81 for processing and are provided for the maintenance terminal 83 for use.

If the battery voltage value is detected to be larger than the rated value, the battery is discharged for a period of time t, then the current magnitude is detected, and then whether the battery voltage magnitude is smaller than the rated value is detected again, and the process is repeated until the battery voltage is detected to be smaller than the rated value. The temperature information of the battery is transmitted to the processor unit 81 to judge whether the temperature is over-temperature, if the temperature is over-temperature, the maintenance terminal 83 alarms, and the charging or discharging process is automatically stopped.
