Energy-saving and consumption-consuming hybrid city bus prototype was successfully developed in Tianjin

Tianjin Qingyuan Electric Vehicle Co., Ltd. is responsible for the research and development of this passenger car prototype. The sample car adopts series full hybrid drive mode, with advanced design scheme and reasonable structure. The auxiliary power unit in the series hybrid system adopts the combination of engine and generator, adopts the two-variable controllable active control load output mode, which effectively avoids the power impact during the startup and load change of the system power components.

The launch of the prototype car mainly relies on the company's own technical strength, and the proportion of original innovation and integrated innovation is relatively high. In particular, breakthroughs have been made in the application technology of hybrid city buses such as vehicle design, multi-energy distribution design, and electro-adhesive management system design.

Experts said that the research and development content of this achievement is complete, the research and development technology route is reasonable, the relevant information is complete, and it can be used for mass production. Its promotion and use is of great significance to the in-depth development of China's automobile industry, especially city bus. The reduction of air pollution and the implementation of urban bus priority strategies will play an active role.
