Power Distribution Unit (PDU) Repairs for Electric Vehicles in China
EVS PDU Diagnostics & Repairs for Safe EV Performance
Tell Me When You OpenAbout the Service.
The Power Distribution Unit (PDU) in an electric vehicle is responsible for managing energy flow between the high-voltage battery, inverter, motor, and other electrical systems. When the PDU is compromised, it can lead to reduced performance, system errors, or even safety concerns. At EVS, we will offer diagnostic testing and repairs for PDUs to restore proper energy routing and keep your EV operating safely and efficiently.
Benefits of PDU Repair
Restored Energy Flow
Repairs ensure that power is delivered correctly to the motor, inverter, and accessory systems.
High-Voltage Circuit Diagnostics
We identify malfunctions related to internal fuses, contactors, or circuit boards.
Improved EV Performance
A properly functioning PDU helps deliver consistent torque and acceleration.
System Fault Resolution
Fixes warning lights or drive errors triggered by power distribution imbalances.
Thermal Load Balancing
We verify cooling functions and thermal protection to prevent overheating.
Brand-Specific Support
PDU diagnostics are tailored for EV platforms like Tesla, BYD, Zeekr, and more.

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.
