The 4th World New Energy Vehicle Conference (WNEVC 2022) will be held in Beijing and Hainan from August 26 to 28 in a combination of online and offline. Huawei Digital Energy brought smart electric products and solutions to this conference, and shared with global industry experts and industry elites the successful experience and development trends of new energy vehicles in technological innovation, industrial innovation, and cross-border innovation, and explored electrification. , the key path of intelligent, shared and coordinated development, build industry consensus, and accelerate the electrification process of the automotive industry.

As the highest standard and most influential annual conference in the field of new energy vehicles, WNEVC has attracted the participation of the global auto industry. Smart electric is one of the sub-businesses of Huawei Digital Energy. It adheres to its positioning as a component supplier and provides competitive products and solutions to automobile manufacturers and partners. At present, Huawei Smart Electric has cooperated with more than 15 domestic and foreign mainstream car companies.

Issues such as charging, battery life, safety, and cost are still the main concerns of consumers when purchasing new energy vehicles. In order to bring consumers a better driving experience. During the conference, Huawei Smart Electric demonstrated innovative technologies such as the DriveONE full-stack high-voltage solution and the four-in-one on-board charging system.

Based on years of accumulation of digital technology and power electronics technology, Huawei has released the industry’s first full-stack high-voltage solution for 800V power domain. BMS and thermal management (intelligent car control) all support 800V high voltage, which can achieve 200 kilometers of driving in 10 minutes, truly fill a cup of coffee with energy, and improve the user’s charging experience.

In the future, Huawei will launch a full-stack solution based on a “kilovolt” voltage platform that can replenish 200 kilometers of energy within 5 minutes of charging, enabling a charging experience like refueling. Secondly, on the power side, it can accelerate to 100 kilometers in 3.5 seconds; on the battery life side, it can increase the battery life by 4.5%; on the passenger side, it creates a library-level quiet experience; on the safety side, Huawei DriveONE-Cloud terminal cloud battery management system, realize 24 hours in advance warning of battery thermal runaway to ensure safety.

Facing the future, functions such as L3 and above autonomous driving have put forward higher requirements for high-safety power supply. At the same time, consumers are pursuing a superior in-vehicle space experience, and components need to develop in the direction of miniaturization and high density. Huawei launched the industry’s first DriveONE 4-in-1 vehicle charging system for future high-end autonomous driving and smart cockpits. Compared with the traditional dual-lead-acid redundant low-voltage power supply scheme, the overall volume can be reduced by 70%, and it can meet the power supply requirements of functional safety ASIL D level, bringing a higher driving experience.

Peng Peng, vice president of the smart electric field of Huawei Digital Energy Technology Co., Ltd., delivered a speech at the “Technical Discussion – New Energy Vehicle Electric Drive Technology Innovation” summit of this conference, and said that the development of new energy vehicles is an important part of achieving carbon neutrality. To maintain the rapid development of energy vehicles, it is necessary to pass the three hurdles of “technical, safety, and profitability”, and to solve the four major concerns of “charging, battery life, safety, and cost”. Improving the vehicle voltage platform and developing high-voltage and high-power charging is the only way to solve the problem of charging and battery life. Huawei Smart Electric will continue to invest, adhere to an open ecosystem, and work with industry partners to promote the full electrification of the automotive industry.

Huawei Smart Electric adheres to the concept of “Huawei does not build cars, focuses on ICT technology, and helps car companies build good cars”, and is committed to helping car companies build good cars, leading the electrification of the automotive industry, and accelerating the power field. Intelligent, bringing excellent power experience into everyone’s life.
