Changjiang Electric Vehicles were designed out of the box, changed the traditional method of "transforming fuel vehicle", devoted in developing the most reasonable, the safest electric vehicles through forward engineering, to better meet the customers’ needs. Since industrial investment from 2010, Changjiang Automobile has been establishing a closed recycling industrial chain of new energy vehicles with its world class electric driven technology. After many years of innovative R&D, the company has developed the core technology of "three electrics". In the battery business, the power battery made for vehicle products through forward engineering has been in the EV market for 6 years, and has acquired the NASA certificate in the US.
In the field of commercial vehicles, the world’s first wheel side electric-driven axles were invented by Changjiang Automobile for light commercial vehicles through independent forward engineering and put into mass production. It replaced the traditional engine, gearbox, clutch, transmission shaft and rear axle, this invention is highly integrated, improves the reliability and transmission efficiency. Equipped with low speed high torque motor drive and built-in IMU, it enables both ESC active control and coordinated re-generative braking strategy, decelerator is driven directly by the electric motor. Newly designed planet sun gear, can satisfy any recovery of torque or auxiliary brake within its peak value; a number of components made of aluminum alloy material, to enable lightweight design.
The battery pack is designed with heating and cooling functions, to ensure multiple protections to the battery system under high temperature or extremely cold circumstances. The techniques in temperature control and active equalization are of advanced level internationally.
In the field of electric control system, Changjiang Automobile developed the whole vehicle control system and battery management system with independent intellectual property rights through forward engineering, and jointly developed the electric control system with strategic partners who has leading technologies at the same time. With independent intellectual property rights, the vehicle was designed with overall planned "brains", best safety strategy and safe bottom design, so as to ensure the safety and reliability of the vehicle.
The vehicle electric control system include: Vehicle managing system (VMS), Battery managing system (BMS), Motor control system (MCS), electric car body stabilizing system (ESS), vehicle networking control system (T-Box).
