Hyundai Kona keeps stopping charging mid charge

I had precisely this issue charging my Kona EV by reference to the vehicle.

The OVO techies advised me that Charge Anytime for the Kona is in Beta testing.

I resolved it by purchasing through OVO an Indra Charger. The benefits of a stable charge at 7p per kWh far outweighs the hassle of repeated mis charges

Hey ​@Djerome 

Sorry to hear about this.

I’m glad to see a couple of community members have already stopped by with some helpful advice.

Thanks ​@BobTom for sharing that, I’m sure it’ll be helpful for lots of people in the community to hear from your own experience! Glad to hear things have been more stable for you since having a compatible charger installed.

​@Djerome Hopefully this has been helpful, let us know how you get on.

Since using Charge Anytime with our Hyundai Kona (2022 model) we have had an intermittent problem in that the 12v battery discharges while charging the main battery from our home charger, a Pod Point. It happens randomly but never when using public chargers. We purchased a new 12v battery after the first occurrence and the car has also been looked at by the Hyundai service team but they could not diagnose a fault with the car. We are therefore wondering if the issue may be related to the App. We have noticed that on some occasions, the charging (always at night) stops and starts up to 14 times. 
Any help or suggestions would be great, the car is proving to be unreliable and if it is the App, we need to think about changing our energy supplier as we don’t want to have to go back to paying a higher tariff.

Hi ​@jillhodges55 ,

Chances are it’s a Hyundai issue - ANY web activity at all is probably keeping the vehicle “awake” and I suspect it’s regardless of source. It could be BlueLink itself causing this.

I suspect a possible vehicle fault or bad vehicle design though.

I have a Kona EV 2024 version and initially I charged with my Podpoint installed in 2019 for my Mitsubishi. It delivered 3.4 Kw which is slow compared to modern home chargers.

It never worked as I would wish with the Kona. It’s not an approved charger and so  I had set the  charging cycle by reference to the vehicle rather than the charger.  I experienced the same intermittent charging issue so I got rid of it and installed an Indra charger.

It works perfectly. Given the fact that the garage cannot find a fault with your Kona that is the route I would go.

As a preliminary measure you could set your car to charge using the Charge Anytime tariff connecting with your granny charger just to make sure there really is no fault with your vehicle. Then I would invest in the Indra which works for me.

I am not affiliated to the company and there are other approved chargers available. I see no reason to move to another supplier but if they put the rate up from 7 p per kWh that would be a reason to reconsider.

Have a look at this link about a dead 12V battery. Now it may not be the issue but if you go on SpeakEV then you can have a look at the various threads associated with this under the Hyundai/Kona section.

For some chargers there has to be a workaround to stop the car falling asleep and being unresponsive when it is time to charge and this can cause a significant drain on the 12V battery by being prodded all the time.

I hope you find the cause.

Hey ​@jillhodges55,

Welcome to the community! 

Have you had the chance to look at the advice left from ​@BobTom and ​@Peter E yet?

Please let us know how you get on. 

Thank you for your advice. It does seem to be problem with the Ovo app, I have emailed their support time for advice and hope to hear back soon.
