What is an electric powered glider? I thought the idea of a glider was it glided and didn't need power?I would think they also would have battery heaters to actually heat the batteries up, I know some of the electric powered gliders have them as they perform best at a given temp and capacity is diminished at lower temps. The one chap I know who has one told me his machine has a modem in it and they can see exactly what is happening in real time back at the factory (Switzerland) and even change parameters etc of the power system (not during flight though) and also spot any issues with defective cells or overheating cells etc. Clever stuff but a bit big brother
tbf i think its a fair comment when some electric cars claiming 300 mile range but can only do 100 under bad conditions, even less if you were towing. youd be hard pushed to find a diesel that cant do 200 miles even towing heavy loads around hills.Good that the range reduction doesn't apply to petrol or diesel cars. Oh wait...
True, but you can fully refuel a diesel vehicle in 5 minutes.tbf i think its a fair comment when some electric cars claiming 300 mile range but can only do 100 under bad conditions, even less if you were towing. youd be hard pushed to find a diesel that cant do 200 miles even towing heavy loads around hills.
They do an electric self launch glider, Antaries I believe it’s called, quite a hot ship, so the motor pops out the fuselage just behind the wing on a pylon. Use it to take off and once up it gets put away.What is an electric powered glider? I thought the idea of a glider was it glided and didn't need power?
No body seems to have a answer for this, certainly won’t be any heat recovery from anywhere when you stuck in one place for so many hoursare you thinking what happens when the battery is flat and your stuck in a snow drift....
As above ,I ask as no water getting heated from engine block.
I often put the aircon on with the heating to get rid of condensation on a cold screen.And why would you have aircon and heated seat on at the same time? Or radio and CD player for that matter?
I do really like that concept, basically a multi source central heating system, but ive got doubts about long term relaibility of these parts of the car. In fact i would be more worried about the long term reliability of this system and all the other internal systems than i would be about any of the drivetrain. I am sure that one day they will get there though, probably when the Japs start making them in a big way.We'll use the Tesla as an example to answer your question, although other EV's deviate alittle, but the latest tesla (the Plaid) is about as efficient as it gets now..
All of them have a regular Lead acid type 12v battery to intially power up the electronics when the car is asleep, and do things like wipers, lights, windows etc when the car is awake . It is charged via the inverter from the main battery pack.
Earlier generations used to use a PTC 3 phase electrical heater to warm the cabin powered via the inverter from the battery pack, as well as a 3phase motor driven air con pump. The Plaid generation now uses a complex heatpump system, and there is a 9 way multi diverter valve for the glycol system , where cooling the motor(s), inverters, charger and battery pack (and warming it under some conditions) heating and cooling of all the parts as necessary.
So the cabin can be heated from surplus heat from the charger or motors, and it can generate heat from the air if more is needed. Likewise surplus heat can be dumped into the air or stored in the battery for later which has a big thermal mass. Similarly the cabin can be heated and cooled via the heatpump. They've got it very very efficient now, such the computers are able to predict cooling and heating requirements from ambient temperatures and historical driving style & distances, so almost no electric is wasted moving heat around that's not really needed.
Whilst all that sounds amazing on paper/as a sales pitch its sounds more complex than it is in some ways. It still doesn't get round the fact that being warm in the cabin is costing you range however they dress it up.We'll use the Tesla as an example to answer your question, although other EV's deviate alittle, but the latest tesla (the Plaid) is about as efficient as it gets now..

Of course, but the heatpump tech uses vastly less power to do so.Whilst all that sounds amazing on paper/as a sales pitch its sounds more complex than it is in some ways. It still doesn't get round the fact that being warm in the cabin is costing you range however they dress it up.
Works both ways mind. When is its cold the system will actually use power to heat the motor battery etc circuit to get it into the ideal working temp range. As i say a lot of it is marketing blurb telling people about a system which they've used for a while without people realising but now using it as a selling point.Of course, b

Hmmmm. It's not my area of expertise I'll admit but i bet if you get in you're leccy car to drive down the road at minus 10 it wants it's system up to optimum temp faster than waiting for heat off the motors.It uses power to move the heat yes, but not to create it.
True, there is a reserve that can be enabled by tesla if the owner drives it til it stops to hopefully enable you to make it to a charger ( its around 15 miles at 30mph ish )a Tesla does have extra battery capacity that Tesla switch on when you phone them if you are not organised enough to charge it up
If any Scandinavian or Canadian TFF members have electric cars it would be great to hear how the electric cars perform at -20 and below.Hmmmm.
