My vehicle is a 2026 EV3 GT Line S. Whatever percentage I use, 80% or 100%, I've seen results. The percentage will drop by 1% the second I open the car door and get in. Could Kia please make it charge to either 80.99% or 99.99%? It's quite difficult.

You can't do what most people would do—set the app's charge cap to 81%. If the automobile seems to cease charging the very second it reaches 80%, then what's the use of 80%? No other electric vehicle that I have had accomplished this.


This is definitely an OCD issue, but I realise that it's not a big deal.

Is that exactly how an app differs from a car?
It starts drawing electricity when you open the door.

When travelling and using the app. Obviously, it's drawing electricity, but is that power consumption anything close to 1%? No, I don't believe so.

How many times you use Connect before getting in the automobile would determine that. The 12V electricity that the drive battery needs to be recharged is being drawn from as the connect wakes up the car to collect the current reading.

It is possible that opening the door is the exact amount needed to cause the percentage reading to decrease by 1%, depending on the exact location of the trigger point for rounding up or down.


Imagine the following: the automobile is at 79.6%, which is equal to 80%, and it suddenly decreases.2%, which would cause a decrease to 79% if it was configured to round up or down at.5

Remember that battery temperature might also affect the percentage measurement.

The original poster has my full support. Putting the Soul on charge at a public charge-point and then discovering that the SOC hits 79% when I drive it a trivial distance home in the morning is equally frustrating to me, even if reaching 81% when 80% was indicated seems incorrect (scientifically).
I am sometimes in Devon where the public charge point is a bit further away and some of the return journey is downhill. My goal is to maintain the specified % while trying to park, therefore I'll have to keep the climate off.
In a nutshell: -

The fact that they only show the SOC with integer precision makes me think that charging up to 80.50% is totally reasonable. Though even at 100.5% the battery should be OK due to its additional headroom, maybe everyone would be pleased if they stopped at 100%.

The vehicle will cease charging when it reaches the 80% threshold and will report 79% as soon as it passes back over the 80% barrier, or whenever power is utilised, if 79 to 80% is recorded as 79z% and 80 to 81% as 80%. The other option is to cease charging at 81%, however it would mean charging to a very low level of 81%. Which others could argue is excessive pricing. In my opinion, a difference of 1% is negligible. I occasionally have Octopus add the necessary percentage to have the target reach about 80% on IOG after setting the objective to 100%; however, it generally ends up a percentage or two off, which doesn't concern me.

Hello, I own an ev3 air lr 2026. Every month, I charge it from around 30% to 100%, and going from 100% takes a little time.

So, to reiterate, the mathematical error margin is +/- 0.5 if a display presents data to the closest unit.
"Car Scanner" monitoring an OBD port reveals this, if memory serves. The vehicle itself is more knowledgeable about the charge status.
When it comes to battery cells, the BMS is primarily concerned with the greatest voltage that may occur on the highest voltage cell. (The shown SOC is an artificially inflated figure that uses 100% as the point at which the BMS reports "enough"—

The charge management team should, in my opinion, go for the 80.49, 90.49, or 100.49 point range. In cases when it anticipates that the user's screen will automatically round to the closest integer.
Just 1% of the battery will be used before the display changes from 90% to 89%, etc.

Maybe it's going down from 100% to 99.99999%, going from 80% to 79.9999%, so it's no longer 80%.

Better things are coming my way. The overnight dip in the garage is 3%. Next week, when the part arrives, the dealer will replace out the ICCU, which I brought to their attention.
