  1. Renault ZOE
    Just wondering how the DC-DC converter works to charge the 12v DC battery under the bonnet? - So i think it charges the 12v battery (if battery is low on voltage ) when the drivers door opens (and when you see the Zoe spinning on the dash) - so what does it do keep charging the 12v does it from...
  2. Renault ZOE
    Hi all, I've had my Zoe for 4 years, and never had any issues charing. But recently, I've been experiencing problems and I think I have now hit a wall. Any help would be appreciated. First problem - it would suddenly not like the charger at home. Error message shown was 'check wall post', and...
  3. ZS EV
    Hi Hopefully a simple question.... We drove the car for a 3 hour round journey (with a full charge in the middle) and when I went to start it today, only 5 days later, the car was dead. It would not unlock and I had to open it with the blade key. What was a shock was that there is only one...

    I have a 20 plate EV Niro, about 13000 miles. Initially I was unable to open any of the car doors with the fob when the problem first started, then I would jump start and have no issues for a few weeks. Now, when I park and turn off the motor, the headlights flash on and off and the door...
  5. Renault ZOE
    Hi all. I have a suspicion this might have come up before, but all the threads I can see on battery drain are about when the car is parked and left for periods of time. Can anyone let me know if the 12v battery is liable to get run down when I'm: A. Sat in here with music and/or lights on...
  6. Renault ZOE
    I'd like to refresh the topic as I couldn't find any definitive advice. Years have passed by and there are now lots of products out there that could resolve the issue with dead 12V batteries after a long parking. I've found both the solar chargers that work inside the car as well as OBD...
  7. General Hyundai EV Discussion
    My Kona 64kwh called the emergency services the other day. The next day the microphone for handsfree and voice control stopped working. I researched, to find that both these things have been signs of an impending auxiliary battery failure. In most cases the owners either gave it a quick jump...
  8. General EV Discussion
    Some of the points in this video apply to other EVs so here you go 😎… Although it is a great car the Kia Niro EV (e-Niro in Europe) is not perfect, like any car on the market. In this video I list the things I “hate” about my Niro EV, now that I have owned it for almost 2 years and over 36,000km...
  9. Renault ZOE
    Hi, Apologies if repeated or noob question! I'm planning on buying the new Zoe later in the year. I currently have an old diesel yaris and regularly use is to run electrical equipment via an oscillator. Can happily draw 2kw from it for a little while with engine off, if more then 10mins I run...
  10. Nissan e-NV200
    Jumped in the van today and warning lights on the dash. Everything was tickety-boo last night when I left so no reason to suspect such behaviour. Pulled the 12V battery out and have it on trickle charge overnight, hopefully this is the culprit as it looks as if it has never been changed in 3...
  11. First Generation Ampera and Volt
    Title says it all really; can the 12v battery be trickle charged whilst connected to the car? Bought a new battery for friends ICE car this morning, tested the voltage to make sure it hadn't drained in storage before being sold. Then thought to test the Volt's 12v battery as been meaning to...
  12. Renault ZOE
    Hi Guys, As I said in my Icebreaker post, I've just installed a dashcam/reversing camera in a Zoe R90. At the moment it is plugged in to the cigarette lighter, but this cuts power shortly after exiting the car (as it should). The dash cam manufacturer (Auto-vox) makes a fuse tap kit to...
  13. Volkswagen Golf GTE
    Hi guys, I need your help, last night I got an error message in my GTE: "not charging 12v Battery". This morning the error has disappeared but the OBD gives me a red fault code: P0D57 Drivetrain fault. I can't find more about this than "Proximity Detection Circuit Range/Performance". Any...
  14. First Generation Ampera and Volt
    Had to get rescured last night, came back to find dreaded 'service steering lock' message, so fixed that by pulling and replacing F2, then got 'service 12v battery' message and all sorts of alarms and flashing displays. When the recovery guy arrived put his 12v jumper pack onto the jump start...
  15. First Gen Nissan LEAF (LEAF24 & LEAF30)
    Hi All, Had a bit of a scare a few days ago. I started the climate control remotely to defrost my car, left it going for about 12 minutes and actually heard it shut off on its own as I got in. When I started the car it said it was in neutral (I left it in park) it also had the 12v battery...
  16. General EV Discussion
    Just returned from 2 weeks holiday in Spain (Costa Blanca) and thought I would bore you all with a few observations. Firstly there are no public chargers in that corner of Spain. Consequently, there are very few EVs. In 2 weeks I saw in total; an e-NV200 utility van, a BMW i3 (rex unknown) and...
  17. BMW i3
    I have front and rear dash cams i want to remove from my old car and put in the Rex. Am i right to think that these can be wired in to the normal 12V car battery system without needing any special BMW service expertise? I ran a portable air compressor from the car's ordinary 12V battery a few...
