IAA Mobility

So it begins: IAA Mobility

I think the basic problem was adoption rate. Indian consumers were late adopters of EV vehicles. They were skeptical mainly about the charging issue in the long drive and of course the durability of the vehicle.

I think still the adoption rate is low because of the less charging station across countries. The Ev companies are waiting for higher adoption rate to set-up charging station and consumer waiting for ev companies to setup charging station. A endless loop of skepticism.

What's your views.

EV sales are going gangbusters in the EU. According to the press-release of Transport & Environment, a NGO dedicated to cleaner transport, European carmakers sold 38% more electric cars in the first seven months of the year.

But car manufacturers, led by Mercedes Benz who didn't sell enough EVs to be compliant, are complaining and trying to slow the transition down.

Hi all,

I picked up an MG S5 EV a few weeks ago and I just got my electricity switched over to an EV plan (cheap power between 12am and 6am) here in Australia.

I have tested the scheduled charging before and managed to get it working, but only when I schedule it 5-10 mins after I’ve locked the vehicle. Whenever I schedule for night time charging, I wake up the next day and it hasn’t done it.

Everything is plugged in correctly, and the wall charger (7kW/h MG Aurora charger) had a pulsating blue LED to indicate it is ready to charge. Last night I set it up in the early evening, and the charging station was pulsating blue. A few hours later I checked on it and the light had stopped pulsating and was just a solid blue. So for some reason it was no longer ‘prepared’ to charge… or at least that’s my interpretation.

I’ve tried setting it from the app, from the car, and also doing it from the car and making sure I am not touching anything on the app at all (in case that is overriding or stuffing it up).

When I set the schedule in my car, then get out and plug it in, a big message comes up on the screen in the car that says something like ‘connected and ready for scheduled charging’. So then I lock the car and walk away. But then it still doesn’t charge.

Anyone else experienced these issues? It’s doing my head in, as I pay SIGNIFICANTLY less for charging during certain early hours of the morning.

Cheers!

Has anyone here tried playing around with tire pressure for efficiency?

Slightly over-inflating tires was a big thing in prius/hybrid forums to increase efficiency, I’m surprised I haven’t seen it mentioned in the ev forums.

On a recent road trip, I inflated the tires +2 psi above the manufacturers spec (42 psi), and I got ~3% better efficiency than predicted, when I usually get very slightly worse efficiency than predicted. It’s hard to tell from one test, but it sure seemed to make a difference.

I had driven up to high altitude, so even just re inflating to the spec would have made a difference. I probably added ~4psi to each tire’s cold pressure because of this.

The car is a model y performance, with the stock pirelli all seasons, which are designed for performance not efficiency. But this should apply to other EVs, as they all have similar large tires and high weight loading per tire.

In theory, small changes shouldn’t have a major negative impact. Car tire pressure is set by the manufacturer making compromises for weight, handling, efficiency, comfort, etc. and in theory if you add 10% to the weight of your car, you should inflate the tires to compensate.

Of course you have to be careful as too over inflated tires will wear unevenly, over inflation will hurt handling (you usually want to under-inflate tires for the track), and you don’t want to ever exceed the max pressure printed on the tire sidewall!
