But it only goes 20 miles on a charge...

Stated endurance is 200 miles with a charge driving hard. Up to stated 300 driving normally.

And how long does a recharge take?

I don't know, IIRC about 9 hours with the high power recharge station and a kton of time on a normal power line but I may be wrong, I'm using the data from the newest Hyundai EV SUV which has as far as I know the largest battery pack ever mounted on a car.

The largest battery pack on a reasonable electric car (not Rimac or Nio for example) is probably Tesla with 100kWh, which can be reloaded in an hour.
But I can refill my car in two minutes.

Sorry, driving it hard only uses 30% more fuel than driving it gently?
It is either slow as f*** or grotesquely inefficient!

or - it's very effective at recovering energy during deceleration, and is very aerodynamic. I.e. it minimises the energy lost during "hard" driving - something which, ironically, is easier to do than when driving conservatively. (A higher proportion of kinetic energy can be recovered via regenerative braking, rather than just coasting to a stop using rolling / air resistance to slow you down, both of which don't allow provide any energy "recapture")
|
|
|
|

Assuming zero drag and rolling resistance:
You lose about 85% to 90% energy in an electric motor, so accelerating and braking with a KERS gets you back 90% of 90%. So you lose ~18%
If you dont accelerate and brake, you dont lose any.
If you do assume drag and rolling resistance then the hard driving case is affect more, because drag is proportional to the square of the velocity. drag = 1/2 * cd * roh * area * v^2.
|
|
|
|
|
You certainly need to assume drag + rolling resistance, or there'd be an unlimited top speed! "Hard driving" doesn't necessarily mean higher top speed (in fact I assume it doesn't, since top speed is normally dictated by traffic conditions and/or speed limits). But accelerating harder and braking harder can be more efficient, especially wrt braking, when using KERS. So a reduction in range of ~30% when driving "hard" seems perfectly feasible in an all-electric car, especially one designed for high speeds and therefore with low drag / resistance.
To the member on here involved with the car's development... do you guys need any testers?

The problem isn't the electric motors, it's the batteries.
When used hard they get hot which raises the internal resistance until they get practically useless until cooled down again. (Or you get a thermal runaway)
That's the reason there is no official times for Tesla around the Nordschleife.
They can't make a whole lap without going into limp home mode.
|
|

|

Hard driving means constant acceleration and braking. Even with KERS you are losing energy because the motor/generator is not 100%.
Add in the higher top speed with hard driving and the additional drag and the energy consumption is much higher than normal driving.

Slow it's definitely not. As for efficiency, I know Jack and s*** about it and Jack is out of town  I was involved with the HMI, for the rest I can only state what they stated.

Absolutely! Actually I have still some support work to do on that but the project is already closed and onwards we move to new horizons.
I so much prefer my new job to the previous one.

It's always nice to be able to have something to point at and say "I was part of that!" Most of what we do as developers is so abstract and ephemeral that we don't often get the chance.

Yeah - Herself would get annoyed by my wandering around supermarkets going "I designed and coded the machine that printed that", until I got her involved in the hardware manufacture for the next generation and then she went round supermarkets going "I built the electronics that made the machine that printed that work".
Even now - fifteen years since I last touched one - I see "my code" being used all over the world!
Nice feeling.

Unfortunately most managers - those who weren't developers - don't appreciate the emotional attachment / pride we can gain from our coding work. One of the first places I worked, I spent 4 months developing one bit of code before moving on to another project; the manager never even let me know when my first "masterpiece" had gone live and I felt very cheated.

The HMI part. It is almost entirely controlled through 2 touchscreen and a driving display.
