TVR Wedge EV Rectification with ChargeheadsUK

Client goal

The problem to solve

The project goal was to help bring a unique TVR Wedge EV conversion safely back to the road. As with many one-off electric conversions, the challenge was not simply making the car move, but making sure the electrical systems, diagnostics, safety logic and supporting systems were reliable enough for real use.

The brief

What VASS was asked to do

VASS was brought in to support the project with specialist EV knowledge, electrical diagnostics and engineering refinement. The aim was to review the vehicle as a complete system, identify the areas that needed attention, and help move the car towards a safer, more reliable and more roadworthy state.

Scope of work

Defined engineering work

• Electrical system inspection
• EV system diagnostics
• High-voltage system review
• Low-voltage wiring review
• Fault finding and system checks
• Control system support
• Engineering refinement
• Roadworthiness-focused rectification
• Practical recommendations for improving reliability and safety

Key systems

Systems involved

• High-voltage battery system
• Motor and inverter system
• Low-voltage electrical system
• Charging-related systems
• Vehicle control wiring
• Safety interlocks and isolation-related checks
• Diagnostics and fault reporting
• Supporting EV control systems

Engineering challenge

What needed careful resolution

• The main challenge with this project was working with an existing one-off EV conversion and assessing it as a complete vehicle rather than a collection of individual parts.
• Performance cars need to do more than simply drive; they need to behave consistently, safely and reliably.
• This meant carefully working through the electrical and EV systems, checking how the different parts of the conversion interacted, and identifying the areas that needed refinement before the car could be treated as a usable road vehicle.

Practical outcome

The result

The project is an active rectification and development project, with VASS supporting the process of bringing the TVR Wedge EV conversion safely back to the road. The work demonstrates the value of proper diagnostics, careful electrical integration and engineering refinement on specialist EV conversions.
