I have searched for the answer on this, but cannot find anything related. Apologises if I have missed the obvious.
We have had the S since mid December and until have been charging it with a 3 pin plug (16 A 4 kw). It hasn't been an issue as it does a very low mileage, typically less than 50 miles a week.
Last week we had a Zappi charger fitted to coincide with the commissioning of our PV system. Initially I tested the Zappi on a fast charge and it put in 7 kw / 32 A as it should do. It is also very good at charging when sun is available and cutting in and out as required, albeit always at a slow state of charge (not a lot of Sun in the South of the UK this week!).
Last night, as an experiment, to prove the system works, we did a boost charge over night during the hours of cheap electricity. It did charge at the correct times, but only at half the rate I was expecting, i.e. 16A / 4 kw. At lunch time today, I set the Zappi off on a fast charge and it was straight up to 32 A / 7 kw I left it for 20 minutes to prove it could do it, then stopped it (expensive electric time). The ambient temp was around 10/12 C.
just now I thought I would try another overnight charge to test the speed, but before I did so I thought I would just check it was still putting in 7 kw / 32 A. Alas, no. Before charging it said 0/32 A. Once charging started it quickly went to 16/16A before ever going any higher. I stopped the charge, waited ten minutes and tried again. Exactly the same. Ambient temp about 2 C.
Is slower charging at just above freezing normal, or is there a fault with the car or the charger?
