EV Mechanical Services in China
Transmission & Drive Unit Repairs for Electric Vehicles in China
About the Service.
Electric vehicle drivetrains are built with high-efficiency reduction gears and integrated drive units—but when these components wear or malfunction, they can lead to torque loss, unusual noise, or poor ride quality. At EVS, we will provide specialized transmission and drive unit repair services for EVs. Using precision diagnostic tools, we identify drivetrain issues and restore the system’s smooth, quiet performance—whether it’s gear binding, internal vibrations, or output inconsistencies.
Benefits of Transmission & Drive Unit Repairs
Drive Unit Diagnostics
We scan for control errors, mechanical faults, and irregular power delivery affecting motor performance.
Gear Reduction Repair
We address wear or misalignment in reduction gears that affect torque distribution and noise levels.
Noise & Vibration Elimination
We resolve clunks, whines, and shakes caused by drivetrain imbalances or bearing issues.
Torque & Acceleration Recovery
We will restore smooth torque output and responsive acceleration, especially under load.
Seal & Bearing Replacement
We will replace worn internal components that can cause leaks or mechanical drag.
Thermal Protection Checks
We will inspect cooling systems that prevent drive unit overheating and performance drops.

Frequently Asked Questions.
Unusual noises, reduced torque, hesitation when accelerating, or vibrations during driving are key indicators.
EVs use single-speed gear reduction systems, not multi-speed transmissions. But these still require maintenance and repairs when damaged.
Yes. Faulty gears or drag from damaged components can impact energy use and overall efficiency.
Most diagnostics and repairs are completed within 1–2 working days depending on the severity and parts availability.
Yes. We will service Tesla, BYD, Zeekr, and most other EV platforms with drive unit-based propulsion systems.
Why Choose EVS?.
02
Advanced Diagnostics & Tools
The centre is being equipped with EV diagnostic software and insulated tools, so issues are handled safely and accurately.
03
All-in-One Service Center
Repairs, paint, batteries, AC - all under one roof, so a car is not shuttled between three shops.
04
Backed by the EVS Group
The Shanghai centre opens with the tooling, the training and the procedures already running in EVS workshops across the Gulf.

View All Insurance ServicesThis work in China
China ended 2025 with 43.97 million new-energy vehicles in use, against a reported 20,000 to 30,000 workshops equipped to service them. The capacity gap is real, and it is widest exactly where the work needs manufacturer-level diagnostic access rather than general mechanical skill.
What we expect to see
Where this work usually starts...
Most jobs arrive one of four ways. Knowing which one you are in changes what should happen next, and what it should reasonably cost.
A second opinion on a large quote
Someone has been quoted a figure that does not sound right, usually on a battery or a drive unit. The useful next step is measurement, not another opinion - and if the first quote turns out to be correct, we will say so.
A fault the dealer could not reproduce
Intermittent faults are the ones that get sent away. They are usually a connector, an earth point or a circuit under load, and they are found with a wiring diagram and a meter rather than by changing parts until it stops.
A car being bought or sold
Pre-purchase inspection on a used EV, where the dashboard percentage is an estimate and a state-of-health test is a measurement. Seven-year-old car with a four-year-old battery is a real outcome, and it is worth knowing before the money moves.
A fleet that cannot afford the downtime
Ride-hailing, rental and delivery operators buy predictable turnaround more than they buy any single repair. That is planned capacity, not an emergency, and it should be arranged before it is needed.
How a visit works
What this will look like when we open...
The Shanghai centre has not opened yet, so this is what we are building toward rather than what you can book today.
01
Tell us the symptom
Not the diagnosis. What the car is doing, when it started, and whether anything changed before it - a service, a collision, a software update, a cold week.
02
We measure before we quote
Fault codes say where the alarm went off, not why. Data streams, actuator tests and circuit measurements say why. The quote comes after that, not before.
03
You get the finding in writing
What is wrong, what it will cost, and what can wait. If a cheaper repair will do the job, that is the one we will put in front of you.
04
The work is verified, not just finished
Anything that needed coding gets coded. Anything that needed calibrating gets calibrated and recorded. A job that was not verified is a job that comes back.
