Dear EV owners and experts,
I have been researching DC contactor reliability in EVs and noticed that overheating and failures are more common than manufacturers admit. Contactors degrade over time, increasing resistance, which leads to energy losses and unnecessary battery drain (up to 5%).
Some key points I’d love your thoughts on:
1. Have you ever had an EV contactor failure? (Or know someone who did?)
2. Do you notice battery range reductions that might be caused by internal resistance increasing over time?
3. Why do automakers still use conventional rigid contacts when alternatives exist that eliminate overheating and welding?
I’d appreciate any real-world experiences, failure reports, or photos of damaged contactors.
Let's discuss how big this issue really is.
Would you trust EVs more if their contactors never degraded or failed?
Looking forward to your insights!
