Every Jinpeng electric vehicle undergoes a thorough inspection and adjustment process before leaving the production line, ensuring high quality and performance. The battery, motor, and control systems are comprehensively tested for functionality and performance to guarantee the stability and reliability of the electrical system. Using specialized four-wheel alignment equipment, the angles and positions of the wheels are precisely measured and adjusted to ensure driving stability and handling performance. The vehicle is subjected to waterproof testing by simulating heavy rain environments, checking body sealing and the waterproof performance of the electrical system to ensure safe operation in rainy conditions. Furthermore, the durability and reliability of the electric vehicle are assessed by simulating various complex road conditions such as bumpy roads, slopes, and bends.
