Project introduction

The objective

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

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.

Engineering challenge

Problem, then system response

01 — Challenge
  • 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.

Commissioning & result

Development outcome

Outcome

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.

For similar programmes

This project is a good example of how VASS can help with unfinished, problematic or previously converted EV projects. Not every client needs a full new conversion from scratch; some need an experienced specialist to inspect, diagnose, refine and safely move an existing project forward. For owners, workshops or content-led builds, VASS can provide practical support with EV diagnostics, wiring, high-voltage systems, commissioning and project rescue work.
