The invention is applied to the field of passenger vehicles and new energy vehicles in the automobile industry. Two fuel engines with half power compared with a conventional fuel vehicle engine are arranged in the vehicle to generate power, and a motor is directly driven through variable speed control. The generated electric energy does not need to be stored and then discharged. A low speed driving state in urban comprehensive working condition is satisfied, only one engine works, and the optimal efficiency of the low-power engine under low-speed driving is achieved. In a high-speed driving mode or a motion mode, the two engines work at the same time, and the demand for publishing output multiplication is met. The invention further provides a kinetic energy recovery and storage system. The brake kinetic energy is collected and stored in the energy storage battery after being stabilized and rectified, the energy storage battery is switched to a battery working mode after being fully charged, the energy storage battery does not need to be specially and externally charged, 100% deep charging is met in the using process, and attenuation is avoided in the service life. The problems of battery weight, charging and discharging of a pure electric vehicle, oil consumption of a fuel vehicle and cost and efficiency of a hybrid power vehicle are solved. The problem that various new energy vehicles are high in cost and price is solved too.

    本发明,运用于汽车行业乘用车和新能源车领域。车内有两台比常规燃油车发动机功率减半的燃油发动机发电,经过变速控制直接驱动电动机。所发出的电能不需要经过先存储再放电工作。满足城市综合工况中低速行驶状态,只有一台发动机工作,实现中低速行驶下小功率发动机的最佳效率。在高速行驶或运动模式行驶,两台发动机同时工作,满足公布输出倍增需求。本发明还设置了动能回收储能系统。收集刹车动能,经稳压整流后存储在储能电池里,储满电切换到电池工作模式,储能电池不需要专门外接充电,使用过程中满足100%深充电,寿命期内无衰减。本发明解决纯电动车的电池重量和充放电问题,燃油车的油耗问题,混动车成本和效率问题。解决各种新能源车成本和价格偏高的问题。
