Consumption

[Lord Randall]

Each 0.1% of gradient adds a ~0.47 kWh/100km at perfect drivetrain efficiency but it's likely to be closer to 0.6-0.7 kWh/100km.

Where I live is 227m my workplace is 179m, that's 48m difference over 26km

So basically, to get more range. Don't go uphill. Don't drive if it's windy. Don't drive if it's particularly chilly out. etc etc. I've got an idea, just don't drive it at all. Just think of the range you'll, get.

Something like that
Tbh, we are all early adopters of new technology. We are mostly different from classic ice drivers, why? Because we want to know more and we ask for more data and want to optimize. Classic ice car have many things that affect consumption (same as ev) but much less data provided to the driver, so people don't look to find "what is wrong", and just go with the flow. EV drivers have 2-3x more data provided and can calculate much better.
For example, to get the same range with different rims on the high speeds I calculated to get lighter rim (not to hard, because mg4 rims are heavy), they are without aero caps, but the consumption is the same. Less aerodynamics, lighter rim, same consumption, I lost nothing and got better looking rims

The other day I just made it to Tebay with 7% in hand, starting from home on 100%. It's about 110 miles (bear in mind that I have the SR). In my petrol car I would have thought that was bloody ridiculous, because that had a 400 mile range, or at least 350 miles under these conditions.

I reckon there was a pretty strong headwind, and it wasn't particularly warm, and I had the ACC set to 75 mph, so economy was poor. But what did it matter? It was lunchtime and I wanted to eat anyway, and Tebay is the best restaurant on that stretch of road. The only difference was that the car was parked in a charging bay rather than in the general car park.

It's a different mindset. Park the car on a charger during the stops you'd be making anyway, and it all works out.

You can't defeat the laws of physics. Or the way current EV batteries work. So drive the car and enjoy the fact that you are not discharging harmful CO2.

And enjoy the way it drives. You're going to have to charge more often than you would have had to fill an ICE car with petrol, but so what? If you're charging at home then that's going to happen while you're asleep anyway, no skin off your nose, it's less trouble than going to a petrol station. If you're out on a long trip then bear in mind it's recommended to stop for 15 minutes every two hours anyway. These breaks in the journey are enjoyable, and you relax more easily when the car is charging, rather than thinking, have I had my 15 minutes, can I go now? If you have the LR battery you can probably get away with 25 minutes every two and a half hours (motorway driving) or something like that.

Even in my SR I drove for four hours non-stop to get to Fort William last month. (Glen Coe was gummed up with roadworks and tourists.) The worst I'll get on the motorway is two hours fast driving, and if speeds are lower or I'm on minor roads it's a lot more than that. Where's the fun in constantly holding back to cut down the number of charging stops or (more realistically) cut the time you spend there? Enjoy the car and the way it drives. And stay warm too.

As an aside, I was driving into Glasgow yesterday evening when I passed one of the petrol stations I used to have to stop at to fill up when I had my Golf. The first thing I noticed was the price - less than £1.30 a litre. The second thing I noticed was the enormous queue of cars waiting to get on a pump. None of them were going to get out of that in less than half an hour. I sped on, thinking smugly about the 7p/kwh electricity that was powering my trip.

Totally, agree.

What sort of speed is this journey driven at? Assume exact same speed in both directions?

If that is the only climbing then the elevation change alone accounts for ~2/3rds of the economy rate difference between out and back journeys. Add a bit for the temperature variance (different air density) and we are not far from accounting for your reported difference. The very lightest of prevailing winds could do it, or even a difference in traffic. And I am also assuming the exact same speed.

Where I live is 230 m and I often drive to destinations at sea level. It's also often the case that the outward journey is done in the afternoon or early evening when it's relatively warm, and then I come back in the very late evening when it can be a lot colder. Also the roads are less congested at that time, leading to a faster average speed. I'm well used to taking several % more out of my battery on the way home.
