Fast Technology March 20 news, this Friday, Great Wall will host the second-generation Hi4 technology conference and the pre-sale launch of the second-generation Haval Xio Long MAX. Wei Jianjun, chairman of Great Wall Motors, said that he will personally conduct the technical explanation.

He stated,The technology of Great Wall Motor is very good, but many people don't know how to express it, which is quite frustrating., as the inventor of Hi4 technology, if I can't explain it clearly, then no one else would be able to, so I will host the press conference.

It is reported that Hi4 technology is the intelligent four-wheel drive hybrid technology released by Great Wall in 2023.Achieving a series-parallel four-wheel drive electric hybrid architecture through dual-motor distributed layout.

Innovative hybrid configurations include a dedicated hybrid engine, a two-speed DHT transmission for hybrids, a high-power and efficient electric rear axle, and low internal resistance power batteries. The dual-motor hybrid architecture on the front and rear axles makes the overall efficiency of EV drive and energy recovery higher, optimizing the energy pathway to achieve optimal efficiency across all operating conditions.

Relying on the high precision of the motor旋变for vehicle speed, iTVC quickly allocates and dynamically adjusts the torque of the front and rear axles at millisecond-level frequency, improving handling stability and driving safety. Note: "旋变" is a term that doesn't have a direct translation in English and seems to be specific to the context. If it's a technical term or abbreviation, please provide its full form or meaning for a more accurate translation.

innovative design of a two-gear electro-mechanical coupling unit, achieving near full-speed range direct drive of the engine, meeting users' all-scenario driving needs.

And the all-new XioLong Max will be equipped with the second-generation Hi4 technology, featuring the first-ever ice and snow algorithm, optimized intelligent four-wheel drive control system algorithm, improved current estimation accuracy and torque accuracy by 6.5%, and reduced mode switching time by 25%.

By optimizing TCU and HCU software, the smoothness of gear shifting and response speed under low-temperature conditions are improved, while the battery control strategy reservoir integral algorithm is upgraded, with feedback power increased by 30%; there is also a significant improvement in battery feedback efficiency, especially in low-temperature discharge power and feedback power.

Not only that, the engine charging model algorithm has been upgraded, the overall system power reaches 238 kilowatts, peak torque is 595 newton meters, 0 to 100 kilometers per hour acceleration in 6 seconds, front and rear axle load ratio close to 50:50, the main drive motor is located at the rear, capable of climbing a 60% grade.
