Xiangyang Tenglong Automotive Unveils Comprehensive Powertrain Test Platform for New Energy Vehicles

Addressing Testing Accuracy and Efficiency Gaps in NEV Manufacturing

New energy vehicles differ fundamentally from traditional internal combustion engine vehicles in four key components: the drive motor, speed controller, power battery, and onboard charger. The quality and performance of these components determine the vehicle's overall value. During the manufacturing process, comprehensive performance testing is essential. However, traditional testing methods are increasingly inadequate for modern NEV requirements. Powertrain testing—covering starting, acceleration, deceleration, braking, and other driving cycle simulations—has traditionally relied on manual measurements, resulting in low efficiency and poor accuracy.

To solve these challenges, the Tenglong Automotive engineering team has developed a comprehensive powertrain test platform designed specifically for new energy vehicle testing requirements.

Engineering Excellence: Multi-Surface Simulation and Precision Measurement

This project introduces several sophisticated technical features designed for testing reliability and versatility:

Dual-Controller Architecture: Two independent controllers separately manage the drive motor and dynamometer, enabling precise control and data acquisition during testing.

Motor-Dynamometer Towing Configuration: The platform employs a towing configuration between the drive motor and dynamometer to accurately simulate real-world road driving conditions.

Integrated Buffer System: Buffer devices are fixed to both sides of the platform's outer frame bottom. Each buffer device includes a buffer frame secured to the inner wall bottom, with a bottom plate mounted on top of the buffer system.

Interchangeable Test Surface: A top plate connects to the bottom plate via ball bearings, with the test platform fixed atop the top plate. This ball-bearing sliding connection allows rapid exchange of different surface materials on the test platform, enabling simulation of various ground conditions including asphalt, concrete, gravel, and wet surfaces.

Braking Force Testing Capability: The buffer device design facilitates accurate braking force measurement while allowing vehicles to easily drive onto the test platform.

Enhanced Testing Range and Accuracy

The platform's interchangeable test surface significantly expands testing capabilities beyond traditional methods. Unlike manual measurements that limit testing scope and accuracy, this automated platform reduces operator burden while delivering more precise results. The system ensures that production vehicles meet rigorous standards for power performance, economic efficiency, and safety.

Proven Results and Intellectual Property

The project has successfully been granted a national utility model patent: "A Braking Test Platform for Electric Vehicles". The platform includes an outer frame, buffer devices at the bottom, a bottom plate mounted on the buffer devices, a top plate connected via ball bearings, and a test platform extending through the outer frame. A vertical plate is fixed to the left side of the outer frame's top.

Commitment to Manufacturing Excellence

This project underscores Xiangyang Tenglong Automotive's dedication to quality assurance through advanced testing technology. By integrating this comprehensive powertrain test platform into our vehicle production and inspection processes, we ensure that every new energy bus, logistics vehicle, and specialty vehicle meets the highest standards of performance, efficiency, and safety before leaving our factory.
