Given my current (no pun intended) problems getting a charger fitted I may end up fitting a 13A socket outside and using that. It’ll be 3x slower than the wall charger but if I only need to charge from 20 to 80% of the 77kWh battery that will be about 45kWh.
On a 10A granny charger that should be about 2.5kW per hour so 18 hours.
Using Octopus Intelligent two nights with 2x6Hrs at 7.5p (30kWh) + 6Hrs at 26p (15kWh) if I leave it plugged in after 6am to top it off would only cost £4.02 per charge. A lot cheaper than my nearest charger (45x59p kWh) £26.55!
Or just shedule it for 6Hrs off peak and connect it 3 nights a week for only £3.37
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
