Further, it is provided with air-duct clapboard between each described station.
Preferably, the cooling device is fan or semiconductor cooler.
Cleaning Principle of the invention is that li-ion cell protection device switch to be measured is connected in measure loop, by heating electricity
Resistance is used cooperatively with cooling device, is switched li-ion cell protection device and is repeatedly automatically shut down or open, and reaches testing goal.If inspection
4 li-ion cell protection device switches to be measured, after main power source and accessory power supply are also turned on, inspection of the invention are mounted with scaffold tower
Flow gauge is as follows：
1）In addition to first cooling device, its excess-three cooling device is worked simultaneously, and corresponding adding thermal resistance is carried out
Cooling, detects first li-ion cell protection device switch situation；
2）After the time of delay adjustmentses, second cooling device is out of service, and its excess-three cooling device works simultaneously, right
Corresponding adding thermal resistance is cooled down, and detects second li-ion cell protection device switch situation；
3）After the time of delay adjustmentses, the 3rd cooling device is out of service, and its excess-three cooling device works simultaneously, right
Corresponding adding thermal resistance is cooled down, and detects the 3rd li-ion cell protection device switch situation；
4）After the time of delay adjustmentses, the 4th cooling device is out of service, and its excess-three cooling device works simultaneously, right
Corresponding adding thermal resistance is cooled down, and detects the 4th li-ion cell protection device switch situation；
5）The above-mentioned steps that move in circles 1-4, until stipulated time or number of times terminate.
Beneficial effects of the present invention are as follows：
The present invention provides a kind of detection screening plant exclusively for li-ion cell protection device switch, by li-ion cell protection to be measured
Device switch is connected in measure loop, by using cooperatively for adding thermal resistance and cooling device, switchs li-ion cell protection device many
