342 batch announcements and 2020 three-electric supplier data, Huawei DRIVEONE three-in electric drive system, motor controller, OBC and BMS have been supported in Sails, SAIC MAXUS, Arcfox, Guangqi Yan, Chengjun , In a variety of models such as Pentium.
Which car power systems have there?
Huawei official website shows that it provides the in-vehicle power system including DriveOne multi-purpose electric drive systems, DriveOne three-in-electric drive systems, end cloud battery management systems, motor controllers, in-vehicle charging systems, and DC fast charge modules.
Multi-electric drive system named sounds, which triggered a wide concern after the release of Beijing Auto Show last year. The reason is that this multi-in-one integrated BCU, PDU, DCDC, OBC, MCU, motor, and reducer, and realize the depth fusion of mechanical components and power components, and intelligently brought into the electric drive system. Realize the end clouds and the control belong to one.
Its seven-in-one electric drive is 120kW and 150kW models. At present, Huawei official website only lists the detailed parameter information of 120kW. The 120 kW electrical drive system is only 65kg, with a size of 410mm * 400mm * 330mm.
The three-in-electric drive system is integrated into motor controllers (MCUs), motors, and reducers. Serialized products adapt to A0 to C-class models, peak power covers 150kW, 220kW, and 270KW.
As software, algorithm, and ecological dominant developers, motor, reducers, etc., are not Huawei’s strengths. Even if you enter the three-power field of the new energy car, Huawei is more good at motor controller, BMS, and OBC with its own software control algorithm.
The motor controller adopts Huawei Self-Research Software Control Algorithm, achieving 98.5% of peak efficiency, in addition to double-sided water-cooled IGBT and integrated design, realizing power density 40kw / l.
The end cloud battery management system consists of a battery control unit (BCU), the battery sampling unit (BMU), and the cloud BMS, supports 0 to 800V battery systems. Its characteristics are combined with big data, AI technology, 1 day in advance to identify battery safety risks and early warning; establish precision battery models, integrate multiple algorithms, improve SOC estimation accuracy; cloud twins system, implement battery full life cycle data can be traced back.
The in-vehicle charging system integrates a vehicle charger (OBC) and a voltage converter (DC / DC), power distribution unit (PDU) optional integration, series of products include 7kW and 11KW.
Since China, it is a smart car solution in building three major domains and three operating systems as cores, smart driving, smart cockpit, intelligent network, intelligent electric and smart vehicles. The vehicle power system is an important layout in its smart driving. Today, these components have begun to appear in the mass production vehicle, helping Huawei deepen their understanding and cognition of the automotive industry.
What is the goods for which models do?
According to the new car publicity list of 342 “Road Map Production Enterprises and Product Announcements”, Huawei will supply DRIVEONE three-in-electric drive systems for Changan CS-GXNEV and Sails SF5.
Among them, Changan CS-GXNEV, the Changan CS95 pure electric version, the front and rear electric drive systems will come from Huawei. The front motor peak power is 195kW, and the peak power of the motor is 230kW.
Sails SF5 will assemble the 255KW electric drive system and the 150 kW of the APC drive system in the autonomous development of Ryers.
In addition, the new energy vehicle for NE data is shown, the Sike SF5, SAIC TC MAXUS Euniq5 has configured Huawei motor controller; in addition, Huawei is Arcfox αt, Guangqi Aion LX / Aion V, Chengchuang 007, Horse love, MaxUseuniq5 and the OBC supplier of Pentium E01; and it is a BMS supplier of Pentium E01.
Most of the above customers have reached a deep cooperation. In recent months, Huawei announced that the new high-end smart car brands and high-end products were jointly built with Chang’an and Ningde Times. It has begun to jointly develop next-generation intelligent electric vehicles, and the two sides have invested more than 100 R & D team; and Xiaokang Three electric, smart cockpit, smart driving, etc.
Obviously, Huawei’s three-electric components began to cooperate with car companies in three electricity, smart driving, etc., more and more appeared in the market. [End]
