New Energy Bus Tech.

Independent R&D on vehicle controller

Ten years of technical accumulation, new vehicle controller (VCU) with independent intellectual property rights has been newly developed to make the vehicle run more efficiently, more smoothly and more intelligently.

Vehicle electrical safety

through six major safety design, improve the safety of the high-voltage system of the whole vehicle, realize early warning of faults and automatically take corresponding measures.

Vehicle power system matching and optimization

Improve product dynamics, adaptability and economy through matching design of motor + electricity, electricity + electricity and electricity system designing.

Communication protocol and fault code system standard

DFTCQG10002-2015.
According to the SAEJ1939 and ISO015031-6 standards, the CAN bus general protocol specification (DFTCQG10001-2015) and the vehicle fault code system diagnostic protocol specification (DFTCQG10002-2015) for pure electric vehicles are developed.
