    The importance of balancing can't be stress enough. I have a 2014 Leaf with 240.000km and 70% SOH. Always charged, 99% of times with the EVSE so very low power. In the first years I always charged it to 100% once a week. Nowadays I charged it almost every day to 100%.

      I wouldn't recommend charging the LEAF to 100% every day, unless you absolutely need to.

      ​@@decimal1815 I prefer to charge it to 100%, as anyway it only sits at that level for a couple of hours. So that in the end of the day it still keeps more than 20% of SOC. I'm confident, it will be better for the battery in the long run.

    What software is on the phone and is that data commonly available on all EV's by the ODB-II port?

      Hi it’s car specific unfortunately - the app is canion and the car is a Mitsubishi i-miev. Leafspy shows similar for the Nissan Leaf and env200, CanZE shows it as a heat map for the Renault Zoe. Cheers

    Hi Gary, are you able to provide battery repair to the public. I have a Peugeot Ion for which the range has suddenly deteriorated by half, and even when fully charged goes into turtle mode within a couple of miles driving (and the battery SoC meter is showing nearly full). I suspect (but currently cant prove as i havent yet got the canion app) some cells have either failed or dramatically gone out of balance. The car only has 11k but has only covered a few hundred miles over the last few years, so i suspect sitting unused and not cycling the battery has done some damage. Do you have a website so i could communicate with you directly. Ive also spoken to the service desk at cleevely ev and beyond the diagnostic they indicated it wasnt something theyd be able to repair (if it was due to bad cells etc).Cheers Chris.

      Hi yes I can do cell replacements but busy for about the next month. I don’t really advertise to customers as I mainly help garages with diagnostics and sell ev parts to trade - if you want me to take it on or recommend somewhere I can do - gclayton@hotmail.co.uk
