Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, a plug/socket high temperature resistant battery management system includes a BMS module, an NTC thermistor module, a charge and discharge MOS transistor, and an input/output plug/socket.
The NTC thermistor module uses temperature sensor to connect the BMS module, gathers the temperature condition of plug department in real time to make intelligent management and control.
One end of the charging and discharging MOS tube is connected with the cathode of the battery pack, and the other end of the charging and discharging MOS tube is connected with the negative end of the input and output plug/socket and is controlled to be opened and closed by the BMS module.
The negative end of the input/output plug/socket is connected with one end of the charging/discharging MOS tube, and the positive end is connected with the anode of the battery pack.
The BMS module is used for controlling a switch of a charge-discharge loop, namely the switch of a charge-discharge MOS tube, processing voltage data fed back by the NTC thermistor module to obtain a corresponding temperature value, and controlling the charge-discharge MOS tube to be switched on and off according to the temperature value.
The utility model discloses prevent plug high temperature battery management system can also have RS485 communication module (not drawn in the picture), can automatic identification and response charging cabinet communication when being connected with the charger cabinet.
The utility model discloses the during operation, the BMS module calculates in real time according to the magnitude of voltage that the NTC thermistor module provided and derives corresponding temperature value, judges whether group battery plug high temperature.
And (3) high-temperature detection of the plug: the NTC thermistor module buries in plug/socket department, and during group battery external device, plug and socket are connected, and plug, socket have the electric current to flow, and on-resistance can pass through the electric current and produce heat, influences thermistor's resistance value, and the voltage that the NTC thermistor module passes through reports BMS module and carries out the temperature data and judges. When the plug and the socket are in poor contact, the conduction resistance is increased abnormally, the long-time large current charging and discharging conduction resistance generates excessive heat, the NTC thermistor module is increased through the voltage value, the BMS module obtains the high temperature of the NTC thermistor module higher than the set threshold value, and the BMS module controls the charging and discharging MOS tube to close the charging and discharging loop and report abnormal protection.
The plug is withdrawn at high temperature: after the charging and discharging loop is closed, no current flows through the conducting resistor, the NTC thermistor module detects that the voltage value is reduced, and after the temperature of the NTC thermistor module obtained by the BMS module meets the normal device threshold value, the device quits the high-temperature protection and recovers the charging and discharging path.
