I did a drive a month or so ago that I knew would be 52 miles one way - Warks to Lincs - actually turned out to be ~55.
Got there with well over half a battery, sufficient that I put the a/c on, on the way back. I'm quite confident it would've done 120 miles again.
But it does come down to driving style - there is simply no way you get that unless you are tuned into the economies of the vehicle - the basic message is try to pull less than 12 kW at all times. Sometime you might need to chug it up a slope, but you just can't go pulling 20 kW out of the battery and expect that sort of mileage. It can be tough to drive like that and you have to be prepared to drive slowly.
The heater energy consumption is pretty hard on the battery. When the winter sets in real hard, I am seriously wondering whether we're looking at some seriously short ranges. We'll find out ....
The pre-heater is good for making significant savings - by heating up the coolant fluids before the battery does, you save a couple of kWh on the range. Once it is warmed up, the heater doesn't use a terrible amount of power, it's the initial heat-up that costs dear.
Your wall-to-wheel consumption sucks. However, this may pass. When I did my first ever full charge, it kept on drawing power for hours after the charging had reach 100%. So much so that I actually went out and depowered the charger thinking something was wrong. I think if it has been used erratically in the recent past (read - parked in a dealer compound for months) the battery needs to do some management stuff to level out the cells. It's just my hunch, and if so then your early figures will look rubbish and you should discard those and start again from 'zero' after a couple of full charges.
My wall-to-wheel consumption has been around the 4.15 miles/kWh mark for the first 1,500 miles. The dash-indicated mileage for the same distance has been ~4.6 miles/kWh, so I appear to be looking at 9% charge losses. Most of my mileage is pottering along the motorway at mid-50s, so I am around the minimum energy consumption.
I'm pretty sure the losses are higher using the 10A lead.
My original reason for logging the drawn energy with my own instruments was to test the Chargemaster logging data. However, my unit doesn't log any data onto the website. Something's not working properly, so I can't say if the Chargemaster monitors drawn energy accurately or not.[hr]
