Comprendre la Chine : un vlogueur belge dévoile le développement de l'industrie chinoise des véhicules électriques

A Belgian vlogger's exploration into Electric Vehicle (EV) manufacturing in east China's economic powerhouse the Yanatze River Delta has unveiled the key factors driving the rise of the country's automotive sector around the world.

Upon arriving in the city of Yancheng, Jiangsu Province, Lucas Deckers visited the factory of Jianhu Yaoning New Energy Technology Co., Ltd., a battery cell manufacturing company of Chinese automaker Geely's Aegis Dagger battery.

Su Zhijie, directeur du département des opérations de production du fabricant de batteries, a présenté à Deckers les principaux processus de production des batteries, notamment la fabrication des revêtements et des électrodes. Il a également expliqué à Deckers que l'usine était stratégiquement située à proximité des usines d'assemblage automobile pour améliorer la compétitivité de ses produits.

Meanwhile, Deckers discovered a test track known as the "Belgian Road" - a rough surface mimicing the cobbles sometimes used in his homeland - primarily used for testing vehicle fatigue and durability. 

Leaving that factory and heading south, Deckers then reached China's business hub Shanghai, with the intention of exploring the realm of electric vehicle design.

While exploring Geely's design studio, the vlogger learned that the design team there develops and executes new ideas, solutions and world-class designs with carving out full-scale design models in malleable clay.

Chen Zheng, Vice President of Geely Auto Group, said that these clay models are created to facilitate the design of their cars in their earliest stages. This is literally the first time a designer's idea appears as a physical object. These sculptures of ideas, will be continuously modified by hand until the design team is satisfied, creating a tangible three-dimensional vision of how the production of cars will eventually look.

Outre la qualité et la conception de la batterie, les performances sont un autre facteur important qui influence l'achat d'une voiture. Deckers a donc continué vers le sud jusqu'à la province du Zhejiang et est arrivé à Ningbo City, où se trouvent les centres de recherche et développement et les usines de soutien de nombreuses marques électriques et hybrides.

"We will test the performance of the battery at low temperatures to see how its reliability and battery life are. We can also do high temperature testing. For example, this device can simulate sunlight. We can raise the overall temperature of the environment to 60 degrees Celsius and simulate strong winds as well," explained Xue Penglou, a test engineer at the research institute.

Dans le même temps, des technologies avancées telles que la 5G et l'intelligence artificielle (IA) ont été appliquées par l'usine intelligente de Zeekr, une nouvelle marque de technologies et de solutions de mobilité électrique appartenant à Geely Automobile Holdings, afin d'améliorer la capacité.

Zhang Yu, directeur principal de son atelier d'assemblage, a déclaré que 60 véhicules peuvent être assemblés en une heure

"We use 5G and Al imaging technology to compare the orders we produce with the physical objects we load onto vehicles to ensure that 1.5 milion combinations can be assembled into the correct parts and delivered to our customers. Currently, this is absolutely leading in the world," said Zhang.

The trip showcased the division of labor that exists within the industrial chain of China's vehicle manufacturing. Jiangsu focuses on supplying batteries and conducting road tests, while Shanghai is dedicated to providing design services. Concurrently, Zhejiang specializes in component making and performance tests.
