EV general discussion

Anyone got the :

Wallbox Pulsar Max Black 7.4kW

Local sparky has recommended it, about £840 fitted including charger cost. Or I just get the hypervolt 3 pro.

The only issue I've had with the Ohme charger is it occasionally tripping out when not in use. It's happened twice now and switching the dedicated consumer unit back on brings it online straight away.

I'm hoping that a few more charges might bed it in a bit and make it more stable.

Has anyone else had this?

I had this a couple of months ago only mine wouldn't reset so I phoned OHME customer services and they said it was down to our mains having a overvoltage. They increased the safety limits a bit so I could charge the car but it ended up tripping again. Out of curiosity I plugged in my £9.99 plug in energy meter and it showed our supply as 252v so I phoned up SSEN who is responsible for the power network up here and they sent someone out to check. By then it had increased to 256v and he traced the fault to the substation around the corner. It has two transformers and apparently one of them was damaged in the storm that went through here on the Monday and the second was trying to take up the slack but was overcompensating. It was fixed that day and the supply was back down to the normal 242v which meant I could finally charge the car. I was the only person to report it as I am the only one with a EV charger on our estate which alerted me that something was amiss. It's worth checking the supply if you have a plug in energy meter.
 
Interesting find! Ohme pro will tell you the volts in the menu on the screen too

Thanks I will look into this. Coincidentally we are the first people in our cul de sac to have a charge point fitted, so it may well be unreported overvolting.
 
@pastymuncher I tested the voltage on a light socket in the house with a multimeter and it read 247v.

I've ordered a plug in socket tester which displays voltage, to make testing easier.

I'll also ring ohme to see if they can run some sort of report.

Looks like it may indeed be the voltage too high.
 
the supply voltage pastymuncher rang up ssen about was within tolerance but they found a higher overvoltage on investigation , so similar maybe true for bainbridge.
eg in the middle of the night when the system is unloaded the voltage peaks higher than 247V causing a PEN trip,
perhaps his supplier will install a temporary monitor/logger on his local circuit, no harm in asking.
(I had problems with water pressure, requiring similar action, where they/water-board put in a logger)

e: watched a review for new kia k4 hatch - why didn't they put a proper similar full hatch door on the ev4 too (even if it is a different platform)

Got my old PodPoint Solo replaced today by a PodPoint Solo 3S. The old charger was tripping for about 2 in 4 charging sessions and we would frequently get up to to our EVs only adding ~10% and the unit tripped.

I phoned PodPoint support but as my old unit was out of warranty I was offered an engineer call out to fit a new breaker box for £210, or a new tethered unit and breaker box for £650.

I have solar and I opted for the new tethered Solo S3 unit as it works directly with my solar panels and annoyingly my local PowerNI provider has reduced the excess electricity payments to only 10p per unit (down from 17p). Considering the cheap rate here in NI is 16p it no longer pays me to export the excess, but to use it to charge the EVs that’s sits most days at home anyway.

No it wasn't. It was 252v and tripped the safety systems in our OHME Home Pro charger. OHME CS raised the limits slightly but as the voltage was still increaasing it tripped out again that night when attempting to charge.

I've just bought a Hypervolt 3 after some research.

Unfortunately I'm on a looped supply so electrician has had to contact DNO (SP Electricity North West) to request unlooping and further instructions if he can install but only charge on a lower power.
 
I'd still have it fitted, running at ~3.6kw is usable for many, and DNO wont have any objections to that, or shouldnt anyway!
