Abstract
The hybrid technology is one of the key technologies of the 100 % low-floor light rail vehicles. Based on technology needs of hybrid power box, a set of power battery and super capacitor adapted to different working conditions was designed, and energy control strategy in noncatenary areas was put forward, taking the dynamic performance requirements including the target vehicle speed, mileage, acceleration, gradient, and dynamic performance requirements of the target vehicle into consideration. Ventilation cooling, dynamic performance, and energy control strategy test results show that the hybrid system could satisfy the requirements of security and dynamic performance of the target vehicle, and also ensure higher energy use efficiency.
