Hello there. My name is Srecko, which means Lucky in English. I'm from Slovenia and I'm an electronics engineer. I'm self-employed and deal with all kinds of electronics. Reason I joined this forum was in search of various information about Nissan Leaf and maybe even share some of my experiences with it. I also produce a version of OpenEVSE modules in my shop.
This spring I got one rather badly maintained Nissan Leaf as a test car for my OpenEVSE modules. It is 2016 made with 30kWh battery, but high mileage of 155,000 and mostly charged on quick charges. Later after we cleaned it and used it as if it was ours, it grew to my wife's heart and we bought it cheaply from my partner company. Battery was very poor and in cold temperatures it didn't go anywhere. Battery SOH was at 61%, but Hx was around 25%. So I bought four MEB packs from VW ID.4, disassembled them and replaced all the battery cells in this Leaf (Boy it sounds easy and quick
). So my wife now enjoys an EV with pretty good range for commuting.
But since that wasn't enough, I accidentally ran across another Leaf Tekna 2019 with 115,000 miles and almost dead battery. It was driven on long distances in hot summer and charged on quick chargers a lot, so the battery almost blew and is having insulation issues. Of course I had to buy it and for this one I ordered brand new battery cells from CATL and they are on their way somewhere around Greece at this point. I will document the replacement procedure in detail and share it, if anybody would be interested. There are some things not yet clear to me about resetting the SOH, bars and reported capacity, but I hope I will find a solution for that too.
If you came so far then thanks for reading and I wish you happy holidays.
