GB44263 DC Vehicle Interface Temperature Protection Function System

GB44263 DC Vehicle Interface Temperature Protection Function System

Equipment model: Sun-GB44263

Production unit: Shenzhen Sunshine Yueda Technology Co., Ltd

1、 Equipment Overview:

We, Sunshine Yueda Technology Co., Ltd., have conducted temperature function protection tests on the charging interface in accordance with clause 9.2.1 of the GB44263-2024 "Safety Requirements for Conductive Charging Systems of Electric Vehicles" standard, which includes 9.4.2 AC charging interface temperature function protection tests and 9.4.2 DC vehicle interface temperature protection function tests, meeting the requirements of GB39752-2024 "Safety Requirements for Electric Vehicle Power Supply Equipment".

2、 Main testing requirements:

The temperature monitoring function of the DC vehicle interface should be tested as follows, and the testing devices for tests 1-5 are shown in Figure 7:

——Experiment 1 Calibration Test: Turn on the heat exchange device (if any), and the DC power supply equipment outputs the rated continuous current. After the temperature rise of the T1 and T1 sensors stabilizes, use the heating device to make the temperature of the T1 temperature sensor reach 105 ℃, and obtain the calibrated thermal fault power Pmin;

For electric vehicles with a maximum charging current greater than 16A, during the energy transfer phase, methods such as applying a heat source and modifying temperature sensor parameters are used to simulate interface temperature exceeding the over temperature protection action value. The electric vehicle should be checked to reduce power output or stop charging, and an alarm message should be issued.

III Main technical parameters:

1. Control system: using branded PLC controller, 7-inch touch screen operation;

2. Heating channel: 2 channels;

3. Data storage: Equipped with built-in data storage function, it can automatically store test data;

4. Data export: Equipped with USB data export function;

5. Equipment power supply: 220V 50Hz.
