Milage

[johnnyallan]

Which is more accurate normal mode or eco, I used my granny charger and
It charged 95 percent from 7pm until 9am next morning, I had 56 miles already and the total milage came 146, is my granny charger faulty, thanks

I top up my car with granny charger for 8 hours everyday and it goes from around 50% to 85 -90%.
say 85 miles to 140 miles on eco.
Just under 7 miles per hour. Your getting around 6.5 miles per hour.
I would say that’s normal.

So, if you mean accurate in predicting range it all depends on how you drive and what you use that drians the battery - e.g. heater, aircon etc. Under eco the hvac is reduced for example. It’s just a prediction based on historic mpk data - nothing more.
Depending on how you drive and what you have switched on you’ll achieve a certain range. Look at what mpk you typically achieve. Say you average 3mpk then you should have a useable range of about 120miles as long as you use the car in the same way. Warmer weather will increase the useable range too. As in all cars if, for example, someone else drives your car in a completely different way then the range will obviously change accordingly.
As far as charging using the granny - you get about 3.5kw/h. So 14 hours should normally fully charge your car. Check your HV pack voltage after a full charge - depending on what BMS software you have it should be c449v or c454v. Your predicted range looks ok but as prevoius;y mentioned it’s based on historic data. There’s lots on the forum about BMS and charging/equalisation and I’ve only scratched the surface. There have been cars with faulty BMS. If you have any concerns get your dealer to check it out

Thankyou you have been very informative, I do have a chargemaster home charger which they fitted 5 weeks ago, but because it had a power surge the fitter disconnected the wires I have not seen him since, very dissappointed

Glad that you found it useful. I hope that you’re enjoying your car.
