Problems solved by technology
[0003] The traditional protection scheme adopts mechanical protection, and avoids contact with the outside world through the charging protection cover. However, during the use of personnel, the protection cover is often forgotten, or even if the protection cover is covered, the external interface has voltage, which poses a safety hazard.

The invention discloses a charge-discharge interface protection device and method for a rechargeable battery. The disclosed device comprises a charge monitoring unit, a discharge monitoring unit, a processor unit, an input output control unit and a contactor unit, wherein a charge monitoring unit is connected with a charge interface; when the charge interface is plugged in a power supply, the charge monitoring unit sends a charge signal, and on the contrary, the charge monitoring unit sends a no-charge signal; a discharge monitoring unit is connected with a discharge interface; when the discharge interface needs to discharge, the discharge monitoring unit sends a discharge signal, and on the contrary, the discharge monitoring unit sends a no-discharge signal; the processor unit sends an oncontrol signal when receiving the charge signal or the discharge signal, and sends an off control signal when receiving the no-charge signal or the no-discharge signal; the input output control unitsends an on or off signal after receiving the on or off control signal; and the contactor unit turns on or turns off connection with the rechargeable battery after receiving the on or off signal. Potential safety hazards geneated by direct contact between a charge-discharge interface for the rechargeable battery and the outside and manual misoperation are avoided, and safety of the rechargeable battery is improved.
Description
technical field [0001] The invention relates to the technical field of battery charging, in particular to a charging and discharging interface protection device and method for a rechargeable battery. Background technique [0002] In recent years, with the rapid development of rechargeable lithium battery technology, the voltage and capacity of battery packs are constantly increasing. The charging and discharging interface needs to be in contact with the outside world, especially through conductive objects, which is prone to safety accidents. [0003] The traditional protection scheme adopts mechanical protection, and uses the charging protection cover to avoid contact with the outside world. However, during the use of personnel, the protection cover is often forgotten, or even if the protection cover is covered, the external interface has voltage, which poses a safety hazard. [0004] Therefore, how to avoid the potential safety hazards caused by the charging and discharging...
