Huawei releases the first electric drive system driveone: charging for 10 minutes, endurance of 200km

11 month 12 Daily news , Recently held 2020 Huawei all in one electric drive system DriveONE conference , Huawei has released the industry's first super integrated dynamic domain solution .

It is reported that , Huawei electric drive system DriveONE Integrated MCU（ Micro control unit ）、 The motor 、 retarder 、DCDC（ DC converter ）、OBC（ Car charger ）、PDU（ Power distribution unit ）、BCU（ Battery control unit ） Seven parts , Realize the deep integration of mechanical components and power components . On the other hand , Bring intelligence into the electric drive system , Realize the integration of end cloud collaboration and control .

According to Huawei ,DriveONE The development of the system is simple 、 Simple adaptation 、 Simple layout 、 Evolution is simple . The specific term ,DriveONE It can help to simplify the layout of the whole vehicle's power domain , Achieve Z To save 220mm, Mounting brackets are reduced 2 individual , The harness is shortened 5m, Fewer connectors 3 individual , Water pipe orifice and water pipe decrease 2 individual .

in addition , Through self research AutoSar, The system realizes the collaborative development of end cloud , Development efficiency has been significantly improved .

In terms of security , The system passes through the car 、 pile 、 cloud 、 Network four item verification ensures zero charging accident , Through the overall visibility of safety 、 The battery is visible 、 Electric drive visibility 、 The complete charging system with visible charging ensures all charging 、 electricity 、 Car safety , At the same time, provide traceable electronic certificates .

As the industry's first high-voltage all in one electric drive system , The system can meet 2C Fast charging experience , Charge 10 Minutes before 200km.

Compared with previous schemes , The system has higher efficiency （NEDC efficiency 89%）、 Higher accuracy （SOC check the accuracy ±3%）、 Less energy consumption , Improve endurance . At the same time, it is also more dense , The power density can reach 2.1kw/kg.

Besides , The performance of the system under extreme working conditions is excellent （ Keep driving at a high speed 180km/h、0-100km/h Accelerate repeatedly 20 Time ）, It also realizes low noise （NVH 78 dB） Low radiation （EMC CLASS 4）.

From the current car owners are very concerned about OTA Upgrade function , The system adopts centralized flat OTA framework , Simplify the path and reduce the complexity of the version while ensuring the performance improvement , Will be common in the industry 10min The upgrade time of is shortened to 30s, In the future, it can realize one click rapid upgrade . On this basis , The system also adopts three-level and multi-level strict control , All around protection OTA Upgrade security .
