My family has a 2012 Nissan LEAF, a blue one that has been with us for some time as well. It also has some problems: the on-board charger, effectively a rectifier (AC to DC) that allows the battery pack to charge, has some problems, and the central screen of the car has malfunctioned (the flippling mechanism), causing a parasite current when the car is parked.

I have the same screen issue as this and similar OBC problems as here, here, and here, but I will have to dig deeper.


This vehicle was part of the first generation of mass-produced electric cars, years before the Tesla Model S first hit the streets—this car in particular was one of the earliest in my town, back when I was 6 years old.

A bit of a personal touch—my dad told me that he wished that I would learn to drive using this car, and I finally got a go with it on my 16th birthday in an empty parking lot.

Since there are some problems with it now, my parents promised me that if I could get the car fixed, it would be mine. As such, I am endeavoring to fix it, upgrade it, and recycle the old battery for use as our home's backup battery supply.


Some stats:

  • 80 kW AC synchronous motor
  • 24 kWh lithium ion manganese oxide battery
  • 192 cells
  • Natural air cooling
  • Battery pack low temperature protection
  • Two-level charging system
    • AC: 110 V and 12 A/240 V and 15 A
    • DC: 480 V and 125 A quick charge
