As electric vehicles (EVs) continue to reshape the automotive landscape, ensuring the safety and reliability of charging equipment has become a top priority for manufacturers worldwide. In response, Sinuo has unveiled its latest innovation: the Comprehensive Tester for Electronic Locking Devices of EV Charging Guns—a state-of-the-art solution for evaluating electronic and mechanical lock mechanisms used in AC/DC EV charging connectors.

This advanced tester has already attracted attention from leading EV manufacturers, R&D centers, and certification laboratories, thanks to its ability to simulate real-world operating conditions including mechanical stress, electrical load, thermal influence, emergency release, and extreme cycling. By rigorously testing electronic locks, the system ensures that charging interfaces meet GB/T 20234.1-2023, IEC 62196-1:2022, and other international standards.

Key Highlights from the Case:

• Simulating Real Operations: The tester accurately replicates normal use, emergency unlocking, and extreme condition cycles, helping engineers identify potential vulnerabilities before products reach the market.
• High-Precision Testing: With axial push/pull force control (0–50N, ±0.5% error) and programmable unlocking force up to 100N, the system delivers repeatable, accurate results.
• Automated Intelligence: Mitsubishi PLC and 7-inch HMI provide manual or programmable operation, real-time monitoring of lock/unlock signals, and comprehensive recording for traceability.
• Durable and Versatile: The device supports up to 99,999 cycles, independent mechanical modules for climate chamber integration, and universal fixtures compatible with GB, EU, and US AC/DC connectors.
• Safety and Reliability: Built-in grounding, overload, and short-circuit protection safeguard both operators and equipment.

In one recent application, a leading EV component manufacturer used the tester to simulate extreme operating conditions, uncovering subtle weaknesses in their locking mechanism. With Sinuo’s advanced solution, engineers were able to optimize design, improve reliability, and confidently demonstrate compliance with global standards.

“Sinuo’s EV Charging Gun Electronic Lock Tester is a game-changer for the industry. It allows us to evaluate every critical aspect of the locking device with precision and repeatability,” said a senior R&D engineer. “And the ability to customize testing solutions to our unique requirements makes it even more valuable.”

Looking Ahead:
Sinuo continues to lead the way in EV testing technology. The company accepts all kinds of customized solutions, helping manufacturers, laboratories, and R&D centers create safer, more reliable, and globally compliant EV charging devices.
