High-Voltage Battery Repairs for Electric Vehicles in China
EVS High-Voltage Battery Repair for Optimal EV Range & Safety
Tell Me When You OpenAbout the Service.
The high-voltage battery pack is the heart of every electric vehicle. Over time, these batteries can experience cell degradation, module imbalance, or power delivery inconsistencies that affect range, performance, and safety. At EVS, we specialize in diagnosing and repairing high-voltage EV battery packs. Our team safely handles disassembly, testing, and replacement of individual modules or components—restoring stable energy output and extending battery life.
Benefits of High-Voltage Battery Repairs
Degraded Cell Replacement
We identify and replace weak or faulty cells causing range drops or performance issues.
Module-Level Diagnostics
Targeted inspection of individual modules to isolate problems without full pack replacement.
Power Delivery Correction
Fix inconsistent torque, voltage drops, or reduced output affecting drive quality.
Safe Disassembly & Handling
High-voltage work is performed with insulated tools and safety-tested procedures.
Improved Range & Efficiency
Restoring cell balance and energy output improves real-world driving range.
Thermal Monitoring Checks
We ensure the battery’s cooling system is functioning properly to prevent future damage.

Frequently Asked Questions.
Reduced range, warning lights, overheating, power fluctuations, or failure to charge fully are common indicators.
In many cases, individual modules or cells can be replaced without changing the entire pack—saving cost and downtime.
No. It's best to have your EV inspected immediately, as high-voltage faults can pose safety risks or lead to sudden failure.
Depending on the issue, most high-voltage battery diagnostics and repairs are completed within 1–3 days.
Yes. We will handle battery repairs for Tesla, BYD, Zeekr, and other leading EV platforms.

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.
