Focusing on EV PTC Performance Validation: ADG+ Covers The Core Testing Requirements

As the EV market continues its rapid growth, PTC heaters are becoming an increasingly vital component. Beyond enhancing cabin comfort, PTC heaters play a vital role in EV battery thermal management systems. Among them, the PTC water heater is experiencing strong market demand due to its outstanding performance, with projections indicating the market will surpass $2.76 billion by 2030.

Testing Standards Centered on VW 80000

As NEV technology advances, automakers are placing greater demands on the performance and testing standards of critical components such as PTC heaters. Developed jointly by Volkswagen, Audi, and BMW, the VW 80000 standard has become the industry’s benchmark for PTC validation. It encompasses environmental, electrical, and EMC testing, and has been widely adopted by leading automakers worldwide.

ADG+ Series: A Purpose-Built Solution for PTC Testing

To meet the demanding testing requirements of PTC heaters, Preen Power’s ADG+ Series High-Power Programmable DC Power Supply delivers a complete and reliable testing solution. It ensures thorough validation of PTC performance—from functional evaluation to extreme operating conditions. This solution was successfully implemented for a leading manufacturer specializing in automotive air conditioning systems and related components.

This solution was successfully implemented for a leading manufacturer specializing in automotive air conditioning systems and related components. The customer required a system capable of high-voltage testing (≥800V) while running three PTC heaters simultaneously. The customer required a system capable of performing high-voltage testing (≥800V) while simultaneously operating three PTC heaters. The ADG+ Series rises to this challenge with its high power density design, providing up to 300kW output power and 2000V voltage capacity in a single unit. This not only boosts throughput but also significantly reduces overall testing time, which is ideal for large-scale production testing.

In addition, the ADG+ Series offers comprehensive protection features against overvoltage, overcurrent, short circuits, and overheating. It ensures precise and stable test results with low output ripple (≤0.05%) and high accuracy (≤0.1%), while maintaining a fast transient response to support dynamic load conditions.

The customer also required strict control over the testing environment and real-time data monitoring. The ADG+ features low background noise (down to 0.2%), effectively minimizing communication interference during testing. It integrates seamlessly with temperature and humidity chambers, salt spray chambers, and vibration shakers, enabling performance verification under a wide range of environmental stresses.

ADG+ series can be custom-configured to meet specific test scenarios. Combined with Preen Program software, users gain real-time connectivity to test benches—enhancing both efficiency and data accuracy. For ease of use and safety, the system includes a 7-inch touchscreen, shuttle knob, and emergency stop function..

From safety protection to performance reliability, the ADG+ Series provides a solid and efficient power foundation for comprehensive PTC heater validation .
