EV rectification / high-voltage diagnostics
High-voltage diagnostic and rectification work on a Porsche 911 EV conversion. The vehicle was made safe, diagnostics showed isolation faults, the battery system was safely reduced and removed, and a serious rear battery pack issue was identified.
Discuss a related projectProject introduction
Identify why the Porsche EV conversion was showing serious faults and make the vehicle safe enough for the battery system to be inspected properly.
Carry out safe diagnostic work on the EV conversion, investigate the isolation fault, reduce the high-voltage risk and inspect the battery packs to understand the cause of the issue.

Engineering & integration
Commissioning & result
The diagnostic work identified a serious issue in the rear battery pack, including signs of water ingress and damaging electrochemical reaction. Once the findings were shown to the owner, the vehicle was returned to the original workshop for further rectification.
For similar programmes
This project is relevant for owners of unfinished or poorly behaving EV conversions. Isolation faults should not be ignored. A structured high-voltage diagnostic process can make the vehicle safe, identify the real cause and prevent unnecessary part-swapping.
