Pyrofuse replacement (EV & Hybrid)
Pyrofuse Replacement Inside High-Voltage Batteries (EV & Hybrid Vehicles)
We specialise in the replacement of pyrofuses inside high-voltage battery systems for electric and hybrid vehicles across the UK.
A pyrofuse is a critical safety device designed to instantly disconnect the high-voltage battery in the event of a collision. When triggered, it permanently cuts off the electrical connection to protect passengers and prevent further damage or fire risk. However, once activated, the vehicle will not start or drive, even if the battery itself remains fully functional.
Our service focuses specifically on:
- Replacing triggered or damaged pyrofuses inside the battery pack
- Restoring the electrical connection within the high-voltage system
- Bringing the vehicle back to operational condition without replacing the entire battery
Why this service is essential:
After an accident, many EVs and hybrids are considered non-drivable simply because the pyrofuse has been activated. In many cases, the battery is still usable — but the safety system prevents the vehicle from operating.
We provide a targeted solution that:
- Avoids unnecessary full battery replacement
- Significantly reduces repair costs
- Allows the vehicle to start, move, and drive again once the system is restored
What you can expect:
- Safe handling of high-voltage battery systems
- Specialist knowledge of EV and hybrid safety architecture
- Careful disassembly and reassembly of battery units
- Reliable restoration of vehicle functionality
Important:
The pyrofuse is a one-time safety component. Once triggered (usually after a collision), it must be replaced to re-enable the high-voltage system.
