EV general discussion

Most people on this thread can ask all sorts of technical questions or simply how they use vehicles. But a few constantly have a snide dig almost every time they post.

Certain subjects on forums and social media seem to attract this. However most people can learn to filter this out and just read the moderate posts. It's like filtering out extreme reviews on Amazon.

You are one of them

The only person who gets some comment you may describe is Jpaul as he’s been talking about getting an EV for about 4 years now then whilst singing their praises seems to also find reasons why he can’t have one Often funded by Google search’s. You’re new here aren’t you ?

"...Heat does not easily pass back through glass, so it's trapped inside the car. A parked car will always end up hotter than the air around it – usually much hotter. A house or office with windows will also experience this greenhouse effect, but they have a much larger interior space to heat up."...

A laminated windscreen with layers of glass and rubber or whatever makes it not shatter must be decent at keeping the wind out.

Like watching a movie when you've only heard bad reviews, then it's better than you expect.

I've found the heating consumption very high, but on the flip side I've rarely been in a situation where I've needed to turn it off for range. It's either been at the start of ownership when I didn't know what I was doing, or where I trying to see how low I could go. Usually I'm quite conservative, and fill it around 30%. Because I park beside the charger so why not plug it in. Seems daft not to. It's just not been the problem I expected it to be.

Then again I'm not hammering down a motorway mid winter every other day. Maybe that would be different.

Yeah you tend drive a bit slower to get there none stop which is what I explained before and you made out I was some moron as I didn’t use ABRP

You have googled something about solar gain and reflected radiant heat in summer and applied it in winter and used that to argue a point. Yet you earlier said you are surprised at heat energy use in winter ? Its single pane glass, laminated just stops its shattering into a million pieces when it brakes. It’s not safe style uk and double glazed. Obviously it keeps wind out but as you didn’t pick up on the concept of forced convection when I said wind rather than cold airflow hitting a warm object (actually a car moving through still air in this case), completely different to a parked car which someone used earlier

Perfect example here of the issue with this thread. Everyone’s an expert cause they can google something

And yes I challenge everything wrong on here. As somewhere in another galaxy pjaul2 is googling to find info for COUk forums and we would want him posting opinions as fact there.

Hello Mr kettle meet Mr Black, Mr pot black.

Yes got all that and for sure it’s going to keep some heat but it’s still cold !

we all know EVs use more energy in winter unless you saying they don’t now? And that’s not just from warming the cabin up. It’s maintaining it especially at 70mph with a few mm of glass the only thing keeping heat in. But hey physics.

You seem to have lost track of the point. All I'm saying is that pre-heating does not cost as much range as you suggest because you're going to do much of that heating anyway. Because cars retain the majority of that heat energy, you're not losing a KWh from the range vs not pre-heating; you're losing a fraction of that.

It’s very cyclical and quite tiresome when you have driven loads over several years and prob 50k miles.

we are discussing heat-loss / windchill on cars again ! - probably a con for the tesla and thermal conductivity of its laminate roof versus metal/headliner/plastic layers in the others.
(my bmw seemed to have a fibreglass type material that I attached new headliner too)

Agree, it’s the 20min preheats that confuse me. I’m some weirdo who leaves my heat on 16C anyway with heated wheel and seat.

Certainly does. Isn't one of the reasons to preheat other than comfort to reduce the impact on range. So why would it have any effect on range at all.

Considering the money you save over the year the cost of preheating has to be negligible. Cost of heating vs depreciation even less significant. Why would anyone be so negative to a simple convenience. So negative to every aspect..

The recent posts in the Overclockers UK EV General Discussion thread involve heated debates on technical aspects of electric vehicles (EVs), including energy efficiency during winter, misconceptions about heating consumption, and technical explanations about windscreen insulation and heat transfer. Participants are discussing personal experiences, challenging each other's knowledge, and highlighting the impact of internet-sourced "expertise." The discussion also includes commentary on driving strategies to optimize EV performance and frequent disagreements about EV-related opinions.

Reality, I have an EV, It’s called education and discussion about things that are factual. I quote you now ‘your perception is negative’

In any case what do you actually add here except argue every point and often seem to give a view which is opposite to your own earlier. At least I’m consistent
