3、 Standard test requirements:

The temperature protection function of the communication charging interface should be tested as follows.

Experiment 1 Equipment over temperature protection test: For AC power supply equipment using connection method A or connection method B with a maximum charging current greater than 16 A, or three-phase AC charging with a maximum charging current greater than 32 A (AC), during the energy transmission phase, the AC power supply equipment operates at the rated current state. By applying a heat source, modifying temperature sensor parameters, etc., the temperature of any power terminal of the simulated power socket or vehicle plug exceeds the over temperature protection action value, and the AC power supply equipment can reduce the PWM duty cycle or cut off the AC power supply circuit, and issue an alarm message.

DC vehicle interface temperature protection function test.

The temperature protection function of the DC vehicle interface should be tested as follows1~experiment5 The testing device is shown in the figure7 As shown. If necessary, the structure of the charging connection device can be slightly damaged, and the impact of structural damage on the temperature characteristics of the charging connection device should be minimized as much as possible.experiment1 Calibration test: Turn on the heat exchange device (if any), output the rated continuous current of the DC power supply equipment, and waitT_SandT_1 After the temperature sensor stabilizes, turn on the heating device and adjust the heating power toT_1 The temperature of the temperature sensor is stable at105 ℃Obtain calibrated thermal fault powerPmin.experiment2 Yong JiuSlow fault test: Turn on the heat exchange device (if any), output the rated continuous current of the DC power supply equipment, and apply thermal fault power at the same timePminCheck if the DC power supply equipment is functioning properlyT_1 temperature reaches105 ℃Before, reduce the charging power or trigger a fault shutdown.
