[0009] In some embodiments, a combustion detector is fixedly provided at the middle of the rear wall of the discharge chamber, and the combustion detector can detect the temperature in the discharge chamber to determine whether the battery has a combustion or explosion condition.

[0010] In some embodiments, four discharge resistors are fixedly provided on the rear end face of the cabinet, and the upper and lower sides of the front end face of the discharge resistor are connected to the rear end face of the connector on the same side, so as to consume the electric energy of the battery.

[0011] In some embodiments, a working detection light is fixedly provided on the upper end surface of the discharge resistor, and the working detection light can detect whether the discharge resistor on the same side is performing a discharge operation, and emit light of different colors accordingly.
