"fast" charging at 1.4kw?? (Zappi V2)

[frb123]

Hi all

Slightly weird behaviour from my car this morning.

We got back from a fortnight in France yesterday eve (almost entirely successful and lots of free vending! But that's another story) showing 10% SOC. It had been fast charged only on the continent, approx 5 or 6 times over the last couple of weeks.

Similar to another thread of mine previously, I woke up to drive to shop, for the car only to show 1% (which then jumped to 2%) and all sorts of scary warnings about stopping and charging immediately. Thankfully the shop is only 0.5mi or so.

NOW, I've plugged in to charge (solar+grid) but even whilst on "fast", it's only charging at 1.4kw. Notably it did peak up to 7+KW on a couple of occasions. I have solar diverting from the charger to the grid as the car doesn't seem to want to take it.

Perhaps because I ran it so low? Anyone experienced this before or any thoughts?

Have you tried turning the Zappi off at the CU for ten minutes and is anything set in the car

What is the "CU" and how do you turn it off?

Nothing set in the car. (Except charge to 100% - suspecting it may need to be balance charged)

Consumer unit. You may have a separate mini CU marked up EVSE or it maybe in the main CU but should be marked for the car

Just a couple of suggestions - Possibly grid limit settings? Are you running latest firmware?

So far as I'm aware it's latest firmware. No grid limit settings that I'm aware of - have charged at the "full" rate on numerous occasions prior.

Curiously, after the above the car was driven again when it hit about 19% SOC (through necessity) down to about 10% ... when plugged in then, went straight to 7.3 KW quite happily. Very odd. I can only guess it was a BMS thing or something to do with it being a v hot day?

Most odd..

Cheers anyhow!
