How many digits does an electric vehicle motor number have?
3 Answers
Electric vehicle motor numbers consist of 17 digits. Below is relevant information: Numbering: The information contained in an electric vehicle motor number includes voltage, current, rotational speed, model version number, and batch number. Only after checking the frame number and motor number of the electric vehicle can you fill them in during the reservation process, which facilitates the licensing procedure. Electric Vehicle: Also known as an electric-powered vehicle, it is divided into AC electric vehicles and DC electric vehicles. Typically, the term refers to vehicles that use batteries as their energy source, converting electrical energy into mechanical motion through components such as controllers and motors, with speed adjusted by controlling the current size.
When I bought an electric car last time, the salesperson told me that the motor number is usually 15 digits, consisting of numbers and letters, located on the label sticker on the motor housing, and needs to be photographed and saved for registration. After I bought the car, I tried to find it myself, and it can be seen near the wheel axle. The fixed 15-digit number makes system identification easier, used for warranty and anti-theft purposes. If it gets worn or blurred, it’s really troublesome—my friend encountered this issue and had to pay to get it reissued. Remember to regularly check and clean that label to avoid accidents. Nowadays, license plate inspections are strict, and this 15-digit number is essential—it helps record the production date and model, allowing mechanics to quickly match new parts, saving time and effort.
Those who frequently work with electric vehicles know that motor numbers typically range from 15 to 17 digits, varying by brand and model. Based on my research, standard domestic models usually have 15 digits, while premium imported ones may extend to 17 digits, including manufacturer identification sequences. The number is located on a label on the motor's side—be careful not to wash it off during car cleaning. Similar to a vehicle's VIN, this number serves anti-counterfeiting and data management purposes. Memorizing the correct digit count helps avoid fake parts traps—I've verified this while repairing cars, with 15-digit codes being most common for easy recording. Extra tip: Winter cold tends to accumulate dust, so regular wiping is sufficient.
