Suzhou Hehang has a perfect forward development system, from the definition of the vehicle, the three power system, the power system matching is in the strict international standard V mode development process, in the HIL system test, has the most fault case base, which is the accumulation of many years. In terms of software, the amount of code is the largest (more than 10 times the MCU), the ordinary single-chip microcomputer storage space has been unable to meet the requirements, the main reason for the large amount of code is fault diagnosis, identification, working condition adaptation code, the more fault cases, the greater the amount of code, automatic transmission is also the most intelligent, reliable, working condition adaptability is also the strongest, is also the biggest barrier in the industry.

         Has a solid industry foundation and R & D capability to support the overall technical route, including: (1) Top-level design efficiency matching theory and matching method, (2) Controller development platform & development process, (3) controller software system (application layer), (4) controller test system, (5) after-sales service, (6) R & D production system, (7) production and quality system, etc

        Special vehicle design matching and control technology, large speed ratio, large torque, automatic clutch, external cycle thermal management system and intelligent network and other unique key technologies, through matching and control core technology, all-round protection of the power battery, especially affecting the actual service life of the battery discharge rate, operating temperature, SOC operating interval, and so on. According to the optimal state of the battery design matching and control, to ensure the longest life of the power battery, the minimum attenuation, to achieve the same power battery life, the lowest actual attenuation, the longest service life, so as to reduce the cost of the vehicle goal, is conducive to the promotion of electric heavy truck project.
