Had the vrs iv now for year and a bit. Always used the 3 pin plug to charge using octopus cheap rate on night, 11.30 to 5.30..Its always charged the battery fully even from flat in those 6 hours. 

This week now it's gets to about 86% and that's it, message from app says it's stopped charging, I use an alexa plug to control the socket and it works flawlessly each night, switching off at 5.31. Has anyone else experienced similar issue. 

Is it charging for the full 6 hours,

but because of the cold the battery needs more the 6 x 2.3 kWh or 2.1 kWh (13.8 kWh or 12.6 kWh ) to get to 100%.   Take the meter reading for kWh used during the offpeak tariff.

 

You have losses charging the cold battery / cold ambient temperature.

Just out of curiosity, and this is going to sound a bit odd  but would putting the car under a "blanket"/cover to reduce the cold actually help it?

No because the battery is above the ground and you have the Ground Temperature (Grass frost) and the Air Temperature.  A heated blanket or hot water bottle is not practical.

 

*Charge in a Heated Garage, maybe just not one attached to the house or under it.*

 

You pre-heat an EV,s battery maybe before charging when driving so that it can charge quicker when you get to a DC charger.

Like you pre-condition / pre heat before driving using the energy from your house / charger to have the battery using less energy once driving off.

Also pre-heating the car / vehicles interior.

Basically yet another reason NOT to get a hybrid or electric car then.

Not really for those charging Off Peak Tariff of 7 pence a kWh or less.

14 kWh needed to get 25-30 miles maybe with a hybrid on electric so £1.00 or so. or £1 for 6 hours and then 2 kWh @ 25 pence.  £1.50.

 

My EV last night 7 hours @ 6.7 Pence a kWh, 16 kWh, £1.12. ,  That gives me 3 miles a kWh so 48 miles or so for £1.12

 

If on a 6.6 kW chargers for 7 hours then maybe 45 kWh for £3.10,     45 x 3 miles a kWh is 135 miles.   That is much cheapness.

Odd thing is I never had these issues last year or with an hyundai ionic I owned. I'll try it on for longer than the 6 hours and see how it goes 

My stupid fault... Don't know how but current limiting was switched on
