Having some fun & games with #hyundai servicing of my #kona electric car. Its 7 years old with 8 years warranty on the traction battery, so it's vital to get the state-of-health of the battery. I measured it at 100% via a bluetooth ODBII adapter, servicing reported 73%.

Pretty sure they've confused state-of-health with state-of-charge. A friend suggested next time I should charge it to 20% and see if they will "fix" the battery under warranty 😀

Anyways, decided it was time to do a better measurement and so will track Cumulative Energy Charged & State of charge for a few months via #torquepro and #homeassistant.
