Nezha Automobile launches new Haozhi Technology Brand 2.0, with multiple core technologies on display

According to news on August 22, Nezha Automobile recently released the new Haozhi Technology Brand 2.0 at its Technology Day event, and also demonstrated a number of core technologies, including super computing platform, skateboard chassis, electric drive system, Range extenders and thermal management systems cover pure electric and extended-range routes

In terms of electric drive systems, Nezha Automobile has launched a 180-kilowatt 400-volt electric drive system and a 250-kilowatt 800-volt high-voltage SiC electric drive system. drive system. These systems adopt an integrated structure that integrates the motor, reducer and controller. Its maximum speed can reach 20,000 rpm, and its torque can reach 4,850 Newton meters. It only takes less than 6 seconds to accelerate from zero to 100 kilometers with a single motor, and the noise in the car is also controlled below 38 decibels

According to the editor’s understanding, Nezha Automobile revealed that these core technologies will be open to the entire industry. In addition, they also plan to launch versions 2.0 and 3.0 of the thermal control system in 2024 and 2025 respectively.

In addition, Nezha Automobile also stated that some overseas car companies have expressed intentions to cooperate with their technology, which may mean that in the future, we will see foreign car companies such as Xpeng Motors and Volkswagen collaborating with Nezha Automobile. Cooperation in the field of technology.

The Haozhi supercomputing platform adopts the central area's vehicle SOA service digital EEI architecture and integrates seven core system functions such as intelligent gateway, power control, energy management, and intelligent diagnosis. This platform is equipped with a super powerful AI computing processor with 1,000 TOPS and up to 1TB of car-grade shared storage.

It is reported that the central controller has a built-in NVIDIA Orin-X chip, which can be used in conjunction with the front cabin and three left and right area controllers to achieve high-speed navigation and automatic parking. and city navigation and other functions. Nezha Automobile announced that the product has completed concept design and program demonstration, and plans to start mass production and delivery in 2025. The Haozhi skateboard chassis adopts a new generation of EEI central electrical architecture, CTC battery system and a full wire-controlled chassis. Through the combined design of the integrated die-casting process and the aluminum alloy profile energy cabin, the battery energy cabin is integrated with the body structure, achieving higher versatility, greater load capacity, nanometer-level installation accuracy and higher stiffness. .

According to my understanding, the new Haozhi skateboard chassis supports 400V and 800V dual platforms. It only takes 3.5 seconds to accelerate from zero to 100 kilometers, and the power consumption is 11 kilowatts. When charging, the cruising range can be increased by 500 kilometers in 15 minutes. The maximum speed can reach 200 kilometers per hour. The CLTC cruising range exceeds 1,000 kilometers.

The new Haozhi range extension system adopts an efficient range-extending special AT Jinsen engine has a fuel-to-electricity conversion rate of up to 3.26kWh/L, which has high energy-saving and fuel-saving performance. In terms of high quietness and high integration, the Haozhi extended-range engine adopts a small gap design, the generator is directly connected to the engine, and the flywheel rotor is integrated, which greatly improves NVH performance and also achieves significant reductions in volume and weight.

In addition, according to the editor’s understanding, Nezha Automobile also revealed that the next generation of reserve technology will integrate human-vehicle-road intelligent control, all-in-one integration, and flat wire Oil-cooled generators, etc. are designed to increase the oil-to-electricity conversion rate of the range extender to 3.4kWh/L, and the silent effect will reach 75 decibels. The technology is scheduled to be launched in 2025.

Haozhi thermal control system mainly emphasizes heat pump air conditioning technology, which has the characteristics of low energy consumption, wide temperature range and high integration. Heating power consumption is less than 800W, which can increase battery life in winter by up to 20%. In addition, the Haozhi thermal control system can work at a low temperature of minus 35 degrees Celsius, and the operating temperature in heat pump mode can even reach minus 20 degrees Celsius

Haozhi thermal control system realizes the upper and lower parts of the car The decoupling design is suitable for a variety of models, including cars, SUVs, MPVs, station wagons and pickup trucks. In addition, Nezha Auto said that under this central-region architecture, the vehicle wiring harness can be reduced by 1.5 kilometers, the weight can be reduced by 10 kilograms, and the cruising range can be increased by 5%. The solution has completed conceptual design and program demonstration, and will begin mass production and delivery in 2025
