New energy vehicle technology is advancing by leaps and bounds, and the electric drive system of new energy vehicles has also been upgraded from the "assembled integrated" solution in the initial stage to the "deeply integrated" solution. Since 2015, Jing-Jin Electric(JJE) has been committed to the research and development of an integrated solution for the deep integration of the motor and reducer. In 2017, JJE's "two-in-one assembly integrated motor and reducer" product achieved mass application in light commercial vehicles. After five years of continuous research and development, JJE has developed a high-torque integrated electric drive assembly suitable for medium and heavy-duty new energy commercial vehicle applications.

Based on the leading cooling technology, flat wire winding motor technology, high-frequency noise suppression technology, and third-generation semiconductor silicon carbide controller technology accumulated by the company for many years, JJE launched the first high-torque and high-power "deeply integrated" drive system assembly for the heavy truck market, which is completely independently developed. This unit incorporates strong power output, high efficiency, energy savings, high reliability, automatic transmission control, and all-weather safety protection. The golden combination system of flat wire motor + 20000Nm four-gear box + SiC controller brings users lower cost, higher operational efficiency and higher reliability.

Flat wire motor + SiC controller

Compared with the current assembly integration technology in the new energy market of heavy trucks, the refined electric innovation flat wire motor, four-gear box with fewer gears, and the third-generation semiconductor silicon carbide controller is deeply integrated with a large torque assembly design. This unit also included integration advantages: lightweight, high efficiency, high performance and easy layout. With innovative technical configuration and platform modular design, the unique functions of free trailer, safe downhill, intelligent noise reduction and active anti-shake are especially suitable for heavy trucks requiring high reliability, high performance, high safety and high-efficiency application scenarios.

At the 2022 World New Energy Vehicle Conference, the 49T hydrogen fuel cell heavy truck released by Foton is equipped with the latest flat wire winding technology of JJE’s motor and silicon carbide controller integrated 20,000 Nm output system.

JJE is an enterprise that started to develop and promote the particular transmission system for electric drive earlier. The golden combination of "flat wire motor + 20000Nm four-gear box + SiC controller" and deep integration system of JJE is specially developed for new energy heavy-duty commercial vehicles. It is another benchmark product of JJE.
