This heating temperature protection testing equipment is engineered specifically for temperature protection performance testing of DC charging piles, in full alignment with the requirements of GB 44263. Developed under the intelligent equipment division which focuses on charging pile testing devices and new energy vehicle inspection solutions, it delivers stable testing performance for commercial users across the new energy charging industry. Beyond core compliance testing, it also supports multiple usage scenarios including on-site online debugging, workshop offline testing, and long-term aging testing. The equipment comes with two selectable working modes, allowing users to switch configurations based on their testing objects and workflow demands.
The equipment executes mandatory temperature protection testing for DC charging piles as specified in GB 44263. As temperature protection performance is a critical safety indicator for charging equipment and a mandatory item for market access, this device helps manufacturers and inspection bodies verify whether products meet national safety specifications, reducing compliance risks for market launch. It also applies to offline testing in production workshops, serving as a fixed quality inspection station to verify temperature protection functions of finished products before delivery, and supporting batch testing on production lines.
It supports online debugging of charging piles during on-site installation and commissioning. Technicians can connect the device to field equipment to validate temperature protection logic under real operating conditions, shortening on-site debugging cycles. In addition, it can be deployed for long-term aging testing of charging components, with continuous temperature monitoring and protection performance verification during endurance tests to validate product stability over extended operation. The device adapts to R&D verification, production quality control, delivery inspection, and on-site maintenance links, matching the full-cycle testing needs of business buyers in the new energy charging sector.
This testing equipment supports two distinct working modes to fit different testing objects and workflow requirements, covering both system-level and component-level testing demands. Mode 1 integrates a vehicle simulation system with a temperature protection test heating device. This mode is designed for system-level testing of complete DC charging piles, simulating the full interaction state between electric vehicles and charging piles to verify the temperature protection mechanism of the whole machine under normal charging conditions. It helps R&D personnel conduct full-function joint debugging, fault reproduction, and performance optimization during product development stages. Mode 2 operates as a standalone temperature protection testing system dedicated to charging guns. This mode supports separate testing of charging gun components without requiring connection to the complete pile system, making it suitable for component-level quality inspection and batch sampling in production lines. It lowers the testing threshold for component verification, eliminates the need for complete pile configuration during component testing, and improves detection efficiency for batch-produced parts.
The equipment natively supports GB/T 20234.3 and GB/T 20234.4 national standards, with optional configurations available for European, American, and Japanese charging standards. It complies with a full set of national and international specifications including GB/T 44263-2024, GB/T 18487.1-2023, GB/T 18487.5-2024, IEC 61851-1, SAE J1772, and CHAdeMO, covering mainstream charging standard systems across global markets. For heating control, the equipment supports both automatic and manual adjustment of heating power, with a temperature rise rate ranging from 1 ℃/min to 10 ℃/min. Users can set target temperature rise parameters manually, and the system will adjust heating output automatically to maintain a stable and consistent temperature rise curve throughout the testing cycle. In terms of electrical testing capabilities, the device performs real-time charging voltage and current detection, as well as charging fault protection testing. It monitors core electrical parameters continuously during the heating process, and verifies the trigger logic and response speed of charging pile protection functions under abnormal temperature conditions. With defined measurement accuracy for voltage and current, it provides traceable test data for quality management and compliance filing.

The temperature rise rate of this equipment ranges from 1 ℃/min to 10 ℃/min. Users can set the target rate manually, and the system will adjust heating power automatically to maintain the set temperature rise curve during the testing process.
Yes. The equipment supports an independent working mode for charging gun temperature protection testing, which allows separate testing of charging gun components without connecting the complete DC charging pile system. This mode is suitable for batch component inspection and sampling testing in production scenarios.
For enterprise customers with customized testing requirements, parameter configuration and standard adaptation can be adjusted according to specific application scenarios. The device is designed to fit into existing testing workflows of charging pile manufacturers and testing institutions, supporting stable operation in both workshop and laboratory environments.
