I have a 2016 Kia Soul EV+ and I was wondering at what SOC% the CHAdeMO charge rate dropped to the 6.6kW charge rate of the on board charger. The other day I had a trip where I needed to top up a bit at an Aerovironment 50kW CHAdeMO charger so I had plenty of range to get back to the same charger on my way home. An interesting quirk of the Kia Soul EV is that there is no onboard control the driver can set to tell the car when to stop charging. It will charge to just below 84% and shut off. If the charge is restarted it will continue to charge to 94% and shut off. I have not tried restarting CHAdeMO charging after that point.
The weather wasn't too bad so after the charger first shut off at just under 84% I restarted the charge and used my phone to video the kWh and SOC% reading on the charger display. (FWIW, no one needed the charger so it was a great time to collect some data.) On my return trip the SOC was at 32% so I also videoed the charging from there until it shut off at just below 84%. When I got home I transcribed a good share of the kWh data along with the time stamp of the frame into a spreadsheet and plotted the results. It took 22.25 minutes to charge from 32% to nearly 84% and 19 minutes to charge from there to 94%. >From 32% to about 75% the charge rate was about 45.5kW where the charge rate began to taper down to about 12.5kW at the point of charge termination. Interestingly, the charge rate from nearly 84% was about 22kW. When the SOC reached 90-91% the average charge rate was 7.0kW and 91-92% the average charge rate was 5.7kW. The charge rate just before termination was about 2.5kW. Based on this info it looks like when my car reaches 91-92% I might as well switch over to L2 charging. Note that the SOC% displayed is the display SOC not the actual battery pack SOC. The battery is a little over 30kWh but only 27kWh is available. Thank you Kia for advertising it as a 27kWh pack! Under sell, over deliver.
