Hong Guang Mini? The sales of EV are booming, which makes the market once again see the market opportunities of small and micro electric vehicles. During the 2020 Global New Energy Vehicle Conference, Wuling released GSEV (Global? Small? Electric? Vehicle) platform, interpretation of Hong Guang MINI? The technical system behind the sales of electric vehicles.

Zhao Xiaoyu, deputy general manager of SAIC-GM-Wuling Technology Center, explained the development concept of GSEV platform. She talked about four aspects:
1. Minimalist physical platform, based on the understanding of Sandian, is a brand-new small electric vehicle platform, including safe body, safe setting, excellent chassis adjustment and extreme physical space.
Second, the open hardware platform, modular design, standard interface and intelligent wire control platform adapt to the development of autonomous driving technology.
Thirdly, the integrated software platform has advanced software architecture. Users can input software into the car in the cloud to realize demand customization. It can combine all mainstream development protocols and integrate functions such as automatic driving and intelligent network connection.
Fourthly, the intelligent cloud platform, including automobile data, user data, charging facility data and service data, can use AI algorithm to meet the needs of different users through data mining.
Zhao Liang, head of the pure electric platform of SAIC-GM-Wuling, said that according to users' demands, Wuling redefined the key words of small and micro electric vehicles: large space, good safety, low energy consumption, convenient energy supply and intimate service, and defined the entire Hong Guang MINI through these five dimensions. Eco-industry of electric vehicles.
At the Hong Guang mini-bar? Before EV, Wuling had sold a certain number of E 100 and E200 models, and obtained the stiffness and related data of car body safety test. Based on these data, Wuling proposed a cage body structure to protect the battery in all directions. At the same time, a large number of high-strength steel is used, and the proportion of high-strength steel in the whole vehicle exceeds 50%, which increases the crashworthiness of the whole vehicle body.
In terms of collision safety, the motor rear layout is adopted to reduce human collision injury. In addition, the mass of the whole vehicle is reduced to about 700kg, which ensures the power and economy.
Cage structure
Wuling also rethought the logic of customer service. Shao Jie, director of electrification of SAIC-GM-Wuling, introduced that, based on the actual needs of users, vehicles and Wuling's charging piles are ecologically linked through technical support, so as to realize collaborative big data monitoring of vehicles, electricity, vehicle piles and cloud networks, real-time monitoring of vehicles, fault warning and active push service. Can users use it? App conducts remote diagnosis and physical examination of vehicles, and provides after-sales service and maintenance as needed.
In July this year, Wuling announced that it would build 100 Wuling new energy experience stores nationwide during the year. Up to now, 59 Wuling new energy experience stores have been built. At the same time, Lingling helps App and e-commerce platform form an online marketing matrix. At present, Hong Guang Mini? EV's orders in Lingling Help App accounted for 62%.
Facing the forward-looking technology and future business model, Wuling is seeking a breakthrough through cross-border cooperation. In September 2020, Wuling and CRRC established a joint power electronics laboratory to explore how to transform the high-speed rail marshalling technology into the automatic marshalling technology of passenger cars.
During the Beijing Auto Show, SAIC-GM-Wuling and Suning released the world's first cross-border smart home appliance-Xinbaojun Xiaobiu smart car. This product will use technologies such as the Internet of Vehicles and the Internet of Things to connect the voice control and display screen in the car with smart homes such as televisions, refrigerators and washing machines at home to realize the interconnection of life scenes.
As early as 20 18, Wuling cooperated with Huawei to explore the deep integration of ICT technology and intelligent networked vehicles, establish an intelligent networked demonstration zone and test drive technology. At present, there are nearly 100 unmanned vehicles in operation. (Text/car home? Xiao Ying)
