Battery & Electrical Services.
High-Voltage Battery Repairs
We address issues within high-voltage battery packs, including module faults, degraded cells, and power delivery inconsistencies.
Low-Voltage Electrical Diagnostics
We resolve malfunctions in auxiliary systems, from interior electronics and lighting to control circuits critical to everyday functionality.
Battery Health & Thermal Management
Thermal regulation is vital in Shanghai's climate. We will service coolant loops, thermal sensors, and battery cooling units to prevent overheating and extend battery life.
Power Distribution Unit (PDU) Repairs
The PDU governs energy flow across key EV components. We will diagnose and repair malfunctions affecting inverters, motors, and safety circuits.
Charging Port Repair
We fix damaged or malfunctioning charging ports to restore safe, consistent charging performance for your EV.
Charging Port Conversions
We convert your existing charging port to a different standard, ensuring compatibility with regional charging infrastructure.
Charging Port Upgrades
We upgrade your EV’s charging port for improved speed, power capacity, or support for newer charging technologies.
Sensor & ECU Replacements
We will replace faulty sensors and electronic control units that affect everything from performance readings to safety features and system communication.
Infotainment & Camera System Support
From camera alignment to touchscreen issues, we resolve infotainment and vision system failures common in modern EVs.
Wiring, Fuse & Harness Repairs
We identify and repair electrical shorts, blown fuses, and damaged harnesses that cause intermittent or total power failures.
Home & Business EV Charger Installation
Site survey, load assessment and certified installation of home and workplace chargers, with the electrical work signed off properly.
Frequently Asked Questions.
Dashboard alerts, reduced range, inconsistent charging, or electrical system warnings are common indicators.
Yes — we will offer charging port conversions, repairs, and upgrades based on compatibility or functionality needs.
Diagnostics are usually a same-day job and battery work typically runs to a day or two, based on EVS workshops elsewhere. We will publish real turnaround times once the centre is running.
Yes. We will repair malfunctioning screens, recalibrate cameras, and troubleshoot display or connectivity issues.
We don’t recommend it. Electrical faults can affect critical systems—schedule a diagnostic as soon as possible.

The 2020-2023 cohorts are the ones now leaving warranty, and they are arriving with the first large bills. Before accepting a pack replacement, it is worth knowing whether the fault is the pack at all - a module, a contactor, a cooling circuit or a sensor can present identically and cost a fraction of it.
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.
