Welcome to InsideEVs Forum!

Hello everyone,
I’m new to the forum and excited to join discussions with EV enthusiasts, owners, and technicians! ⚡
I’ve been researching high-voltage DC contactors in EV battery packs, and I’m curious about real-world experiences with their reliability. From what I’ve seen, contactors often fail due to overheating, welding, or degradation, leading to battery pack replacements or expensive repairs.
I’d really appreciate insights from people who have encountered contactor-related failures, whether in Tesla, Nissan, Renault, VW, Hyundai, Kia, BYD, Rivian, Lucid, or any other EV brands:
Have you experienced a contactor failure?
What were the symptoms (e.g., car not starting, error messages, loss of power)?
Was the contactor replaceable, or did it require a full battery pack replacement?
Do you have pictures of burned, welded, or damaged contactors?
Additionally, I’m working on a new type of elastic contact technology that could potentially eliminate welding, overheating, and premature failures. But does the EV industry really need a better contactor solution, or is this problem overblown?
Looking forward to hearing your thoughts and experiences!
 
Hello all.
Have just registered on this site and already amazed by the wealth of information available.
My good lady and I have just purchased a 2021 Kona EV Extended Range (64kWh) with 32K km. It is a ex-state government fleet car, purchased at an on-line auction.
We live in rural south east Queensland, Australia. At our age (late 60s), we often have to travel to a large regional town (115km each way) or the state capital, Brisbane (175km each way). We've already determined that the 'fuel' cost of these trips with be about 1/3 of that for our Isuzu MU-X 3.0L turbo-diesel.
You'll probably find me haunting the Kona forum regularly from now on. Cheers, Ian.
 
I stumbled upon your forum by accident once, but then lost the link. That won't happen again, because I'm already a member hereo_O
