My 2022 Kona EV purchased six months ago would not start and was I clueless on what to do and panicked! Grateful for your video and connected a trickle charger to my 12v battery and a few hours later my car started up. I have no idea why this happened, but headed to the dealership to test the battery. THANK YOU!!!
Another scenario worth mentioning might be that the 12 V Battery even though been on trickle charge for hours does not maintain the charge going into it because its dead anyway and needs a new replacement- jump starting is only a one off temporary solution and once power is turned of will not restart again.
Thanks for the video. i phone up the dealership where I bought the car and explained that the car would not start and totally dead. Could not unplug the main power cable from the car. They were not very helpful and said I need to get the car recovered. As the car was still plugged in that was going to be very difficult. I tried the battery charger idea but I think I need a new battery charger. So I got it jump started and that seems to have worked at least for now. We see tomorrow morning?
Thanks for the video! Helpful and encouraging. Car wouldn't start before I looked at your video. Just affterword started right up. At the repair shop now for new battery. I'm told the batteries last 3 years? Mine is/was 6 years old.
Is there any way to prevent the 12v battery from dying? I'm worried that being inside of my EV6, fiddling with the settings and customization options, without driving it will kill it.
Turn the car on, and the traction battery will be used to power the electronics. If you are leaving the car and want to leave it on, turn on utility mode. During which, the 12v battery will be charging, so no need for a separate charger as in the video.
I have a Mitsubishi Outlander phev, only 3 months old, this morning it was dead. I was able to use a jump start kit to power the car. However as soon as i remove the cable, it went dead again. I had to leave the car running for 10 minutes or so as EV battery charges the 12v battery.
your dash flashes one light when 12v is charging or being charged by the big battery a battery bank can be connected to charge. i would carry both type of chargers for when it does it it not always that the battery is flat its just below the system seeing it it could only need 5 or 10 minutes as soon as you can start the big battery will charge up the 12v faster to full in want could be 15 to 20 minutes
Interesting! Would one of these portable jumpstarters have been enough to start the e-Niro? What was your SOC when that happened? I undetsrand that, with enough SOC (>20%?) the high voltage battery should have topped up the 12V battery automatically, but perhaps you have to chose this option in the menus..
Absolutely. I've just gone out to car this morning with battery charger being on all night and it is still totally dead. I'm just uploading a new video where I have to try jumping the car instead.
If this were a BYD Atto3 in this situation is plug in the V2L Adaptor and the charging system would kick in bring the 12 V to lie again, as the V2L runs off the main battery, this means that you would be able to put the charge back into the 12V by just inserting the V2L Adaptor as this causes the Main High Voltage Battery to say ok we need the power, and the onboard battery charger would charge up the 12V battery to where you can start the car, then the HIgh Voltage battery takes over.
i am not sure but i believe that the kia e soul takes 12 volt from the big battery when the car noticed that the 12 volt battery is to low. is that not so by the kia e niro?
Yep just like normal car. It powers most of the systems. The big lithium battery provides power for the motors to actually move the car and heating etc. The 12v battery gets charged from the lithium battery when the car is turned on, but can go flat if you leave lights on etc just like normal car.
They have seen it happens a lot and came to the logic solution in the new Kona ev to charge the 12V with the big battery also when the "motor" is not running
Howdy, I know the Ioniq has some sort of battery protection mode where when activated, it won't let the 12v battery get below a certain threshold. I should imagine this should have something similar? ua-cam.com/video/OQEgfqMdzQ0/v-deo.html
Yep e-niro has it, but I guess I was drawing more power than was going in to the 12v battery (I was powering something from the 220v socket in the car) and it eventually died. It did takes hours to die though.

Should last 5 or 6 years.

Yes, buying an aftermarket battery, they are expensive but they will last four times longer, they are lithium batteries
@@MrFgarcia140 Where do you buy these?

Good info, thanks mate. Still learning with the e-niro. It was my own stupidity which ran the battery down, hopefully it doesn't happen again.

@@FinlandTony Wow, looking forward to it, good luck!
Thanks for the info, have an eniro as well
Great videos thank you

Your accent sounds like you are from Liverpool, UK. 🤔
Never knew Ev’s had a 12v as well!?

I just jumpstart mine... all fine.
