Product Description
I. Overview
This testing equipment meets the requirements of Clause 9.4.2.2, DC vehicle interface temperature protection function test in GB/T 44263-2024. It can simulate the heating of the gun seat pins and test whether the charging gun can sense the over-temperature, so as to automatically switch the charging pile power supply. The equipment adopts PLC and touch screen control, and the PDI temperature controller automatically controls the temperature to achieve arbitrary adjustment and constant temperature within the set range, and timing function.
II. Standard Compliance
DC vehicle interface temperature protection function test
The temperature protection function of the DC vehicle interface shall be tested as follows. The test device for Test 1 to Test 5 is shown in Figure 7. If necessary, the structure of the charging connection device can be slightly damaged, and the impact of the structural damage on the temperature characteristics of the charging connection device should be minimized as much as possible.
Test 1 Calibration Test: Turn on the heat exchange device (if any), the DC power supply equipment outputs the rated continuous current, and after the temperature rise of the TS and T1 temperature sensors is stable, turn on the heating device and adjust the heating power to stabilize the temperature of the T1 temperature sensor at 105°C to obtain the calibrated thermal fault power Pmn.
Test 2 Permanent Slow Fault Test: Turn on the heat exchange device (if any), the DC power supply equipment outputs the rated continuous current, and apply the thermal fault power Pmin at the same time, check whether the DC power supply equipment reduces the charging power or triggers a fault shutdown before the T1 temperature reaches 105°C.
Test 3 Permanent Fast Fault Test: Turn on the heat exchange device (if any), the DC power supply equipment outputs the rated continuous current, and apply the thermal fault power 2XPmim at the same time, check whether the DC power supply equipment reduces the charging power or triggers a fault shutdown before the T1 temperature reaches 105°C.
Test 4 Sudden Slow Fault Test: Turn on the heat exchange device (if any), the DC power supply equipment outputs the rated continuous current, and after the temperature rise of the TS and T1 temperature sensors is stable, apply the thermal fault power Pm, check whether the DC power supply equipment triggers a fault shutdown before the T1 temperature reaches 105°C.
Test 5 Sudden Fast Fault Test: Turn on the heat exchange device (if any), the DC power supply equipment outputs the rated continuous current, and after the temperature rise of the TS and T1 temperature sensors is stable, apply the thermal fault power 2xPmin, check whether the DC power supply equipment triggers a fault shutdown before the T1 temperature reaches 105°C.
Test 6 Vehicle Over-Temperature Protection Test: During the energy transmission stage, by applying a heat source, modifying temperature sensor parameters, etc., the interface temperature is expected to exceed the over-temperature protection action value (customized by the electric vehicle manufacturer), and check whether the electric vehicle can reduce power output or stop charging.
