A recall incident reveals that a huge part of Tesla’s business is handled by China.Ā From the core three-electric system to the body sheet metal, to the charging gun, and even some hardware of the automatic driving system, all of them are contracted by Chinese suppliers. It appears that Tesla will soon achieve a completeĀ “localization” of its vehicle. Who are Tesla’s suppliers?
Dismantling a Tesla car, we can broadly subdivide the core components into four parts including the chassis, cockpit central control, body sheet metal interior, and charging system. How many of these core components are from Chinese suppliers? Smart car reference sorts this out.
For the battery and charging system, a couple of Chinese companies makes the magic happen. We have the likes of Ganfeng Lithium, Tianqi Lithium, and Shanshan.
For the electric drive system, the electric drive module is provided by Xuri, and the motor part is provided by companies such as Zhongke Sanhuan and Jingda. All these companies are all Chinese.
For the central control system, the central control large screen is provided by BOE, Jingrui, Tianhua Ultra Clean, and a few other companies. Most of the companies in this regard are Chinese
The visual sensor supplier in Tesla automatic driving is Lianchuang Electronics while the high-precision map is from NavInfo. Both are also Chinese companies.
In addition, there are Chinese Tesla charging systems, body forging, battery management systems (BMS), and chassis.

On the whole, there are very few aspects of a Tesla car that has nothing to do with China. Apart from theĀ autopilot chips and algorithms, almost all other aspects of a Tesla car are Made In China. Thus, if you don’t like China but you drive a Tesla, then you should know that you are “swimming” in China.
Tesla’s supply chain
Recently, Tesla recalled some Teslas in China, which is not unusual. After all, recalling vehicles is also a routine operation for Tesla. Unexpectedly, this recall incident brought to the surface the local stakeholder behind a Tesla — Sanhua Zhikong.
The cause of the incident was the Defective Product Management Center of the State Administration for Market Regulation not long ago. The company had to recall 26,047 Model Y and Model 3 produced at the Shanghai factory.
The reason for the recall is that some Tesla (China) heat pump electronic expansion valves will move slightly under certain circumstances. Because the software (version 2021.44 to 2021.44.30.6) does not have a corrective function, it may cause the valve to partially open for a long time. As a result, the heat pump compressor stops working, and the interior of the car may be partially open.
Sanhua Zhikong is the Chinese supplier of Tesla heat pump electronic expansion valves. The core business of this company is mainly refrigeration and air conditioning home appliance control components and auto parts. In this regard, Sanhua Zhikong issued an announcement refuting the blame. The announcement states that Teslaās recall is mainly due to a communication interruption in the vehicle controller. The company claims that this has nothing to do with its electronic expansion valve itself.
