Specifically, the over-temperature shutdown function test is explained as follows, the output of the simulated battery is increased from low to high within the simulated voltage range of the simulated battery temperature, and the charging output can be automatically shut down according to the temperature of the battery when the seat charging is required. The temperature detection of the battery is realized by a sensor inside the battery, and in the embodiment of the application, the simulation of the battery needs to simulate the voltage. When the voltage of a certain battery module is increased, the base charge output is turned off, the battery analog voltage is within the temperature analog voltage judgment range, the test main control board automatically looks at the over-temperature turn-off function voltage to be normal, and otherwise, the base charge output is abnormal.

After the withstand voltage test, the integrity of the seat charging function needs to be tested again to judge whether the seat charging is damaged or not.
