A few weeks back I purchased a 2011 Nissan leaf from Arizona. As you might imagine the capacity in the battery wasn't great, but I got the car for cheap so I didn't care. I was getting about 20-30 actual miles on a full charge. However, 20 miles is barely enough for me to drive into town not to mention getting back! So I started looking at my options.
I could have had the battery replaced by Nissan for over $6,000 but that would have been more than I spent on the car itself. I wondered if batteries from newer cars could be put into the car. I soon found out that would require reprogramming the battery control module so that killed that idea. But then I wondered if the cells themselves could be swapped between batteries. They were the same size, so why not?
That's exactly what I did. I purchased a 2014 pack for around $3,000, dropped the pack from my 2011, and swapped the cells. Overall the job was fairly quick and easy. With it being my first time doing this it only took me about a day. After all was said and done I popped the pack back in and it was charging!
I thought to myself, "Man, that was easy. I was expecting something to go wrong."
I was feeling pretty good. The car was trickle charging with over 10 hours till full. Much better than the 3-4 hours it would take to fill the old cells. I was about to pour myself a nice cup of victory when I decided to check out how the car was doing with Nissan Connect.
The car had been charging for about 4 hours and had around 5 bars worth of charge. I refreshed the page and...nothing. No information was being shown except for the estimated charge time of 6 hours. At the time I was away from the car running some errands so I figured that the app was just having trouble connecting to the car.
I was wrong
When I got back home the car was not charging anymore. I could turn it on but instead of the dash showing (X) number of miles remaining it showed --- and the EV System warning light was on along with both red and yellow Master warning lights. I fiddled around with the gear shifter and when I tried to put it in drive suddenly the miles remaining on the dash returned and the EV System warning light turned off, only to return a moment later. Now the car refuses to shift into anything other than park or neutral.
I used LeafSpy Pro to look and see what error codes it was throwing out. Oh Boy! We have 22 messages! After clearing them 21 codes came back. I tried to drive but I only could put it into neutral. Then the 22nd code returned as p31e7 EV/HEV Restart Inibition EVC-310. Google returns nothing on that.
So that's where I am now. An idiot with a possibly bricked car, 48 old cells laying in the garage, and no idea where to begin to solve this issue. Any help would be appreciated.
