A little bit of "question time".
Did you leave home at 10 AM at 100% full charge (12 of the wide bars on the right), if not, why not?
The car didn't come with any charge cable and when I turned the car on there was only about 40 miles let, enough to drive to the 80% rapid charger Where I managed to get the charge showing 87 miles.
Does the car have all of the capacity bars (the little bars on the right)?
How many miles on the car?
What was the temp outside? How much did you use the heaters?
I can't remember exactly but it wasn't cold war or hot and no heater
Have you checked your tire inflation (should be at least the recommended pressure, many people go higher, closer to limit stamped on the tire)?
did the tyres before setting off and set the pressure at 40 PSI
Did your car come with a charging cable, and is there any volt/amp/watt rating on the labels/instruction?
No the car didn't come with a charger, I've picked one up for Nissan when I got to the channel shuttle service it is 240v 10A charge of that would normally come with the car in the UK, if there is a way of adjusting the unit I would like to know as most of the supplies available to me are over 16A or more.
Given it is a 2011/2012 and highway driving, I would have targeted getting at least 4 miles/KW, so for 150 miles you would have 37.5 KW. Starting with ~20, that would have meant stopping for 3 hours twice, picking up 10 KW each time. (you want to charge it from 3 bars back to 10, get moving, and then do it again down the road, that last two bars takes longer as the charging rate slows down). With experience and learning to choose the scenic route, you can shorten your travel time by going slower, (30 to 40 MPH), which will lead to 5+ miles/KW and only have to charge up once.
I really dislike being overtaken by big trucks and as most tracks travel at around 60 I find it feels safer just to stay behind one, driving the scenic routes is an interesting option and I have noticed that driving in town the range seems more realistic with what is left in the battery.
Glad you made it! You are braver than most, diving straight away into a 150 mile journey.
I did a little research before setting off, I think the saying goes a little information can be a dangerous thing, but I found it a good way of getting to know the car quickly and I'm planning a new journey which has two routes one on the motorway and one on the scenic roads, it boils down to a balance between speed and range, thanks for the advice on the 3 to 10 bars.
