Hi everyone,
I’m a new Leaf owner, just bought a 2019 SV a few weeks ago. I’ve installed the stock Nissan L2 charger in my garage that came with the car and have been looking for an easy way to stop charging at 80%. I came across some anecdotal comments that the charger should start drawing less current around the 80% mark and therefore that could be detected and acted on accordingly. I’m very familiar with Arduinos, coding and some light electronics work so it seemed like something I could handle. So I tested my charger today with my clamp on ammeter and from 50% to 91% SOC it was always pulling ~27.5 amps the entire time. I was expecting to see a several amp drop but alas there was none. I stopped charging at 91% as this seemed to be a non-starter.
So my question... is anyone familiar with the “tapering off” these chargers are supposed to do, if any? The only drop I saw was a couple hundred milliamperes while in the low 80’s but that went up again after several minutes.
If this doesn’t work I may go back to my idea of integrating with the carwings API, but I was hoping to avoid that as it seems unreliable at best.
Thanks!
