Chief Executive Officer of Jaguar Land Rover Thierry Bolloré today announced a single word that explains the company's new global strategy: “Reimagine.”

What exactly does that mean? An all-electric lineup for Jaguar and Land Rover “by end of the decade,” as well as the “start of journey to become a net zero carbon business by 2039,” apparently.

The first of these new …

In reply to Colin Wood :

Not just Jaguar. we're talking about 1/3 of manufacturers have said that to some degree or other.

I look forward to heated forum debates in 40 years about whether the Jaguar EV system is superior to the GM system or not

Thus far, I think the Jaguar 12V system is interior.

How long are the lines going to be on long weekends when you need to "juice up" to get home ?

Even if they get down to 10-15 minutes  it  could be a long wait in line , 

with luck battery tech will get so much better that this post will look stupid in 5 years , 

I remember the Beach Party movies from the 1960s where the guitars were plugged into the sand :)

Well, you could be smart enough that your weekend hotel has a destination charger so the car fills over night and then you don't have to charge before heading home. And you don't need to fully charge every time - a Tesla on a Supercharger will get to 80% charge in 10-15 minutes already, and that's enough to get you another 4 hours down the road. EVs work differently than gas cars in a bunch of ways. But yeah, under certain conditions it may not be ideal. That makes up for all those times you have to stop and stand in the rain while filling your ICE with fuel :)

The thing to remember is that this is a plan for 9 years ahead, and even then it's going to take a long, long time before the majority of the cars on the road are EVs. The infrastructure will be building out over that period as well.

Ohhh I agree , and Tesla Superchargers may be "slow chargers" in 5-10 years ,

Right now I think GM is ahead of everyone except Tesla on EV's.

There was an inventor from Israel who claimed he could charge a EV's battery in 5 minutes. About the time it takes to refuel.  Questions abound but there are some extremely clever people out there.

At some point, physics will take over, and the speed of charge will be limited to prevent things from melting.  Even if there's a magical superconductor system running from the power generation to the battery- the battery will have a limit on speed of charge.  

But I'm sure people will continue to discount that.

You want cars? Too bad, we only make SUV's now.

You want gas engines? Too bad, we only make electric now.

You want attractive? Too bad, we only make ugly, horrendous front-ends now.

It will suck to be a luxury car buyer in the near future.

Ha ha. Clever.   I'm flexible enough to realize that pistons sliding up and down with one stroke in 4 making power may be at the end of their life as prime movers. 
   I'm ready for an EV and chances are it won't be an import.

The market will reward manufacturers that build cars people want.

Lets say that the charge would be the equivalent of 4l of gasoline- that would end up being 420kW of power for the equivalent of one gallon of gas power in 5 min- without losses, ~650A and 650V.   30 years ago, we were melting dirt in the desert with that same output.

It would be amazing if someone can pull that off.

What if a burst of charge would hit each cell at a different time?  Giving each cell a chance to absorb the charge and cool off?  Sort of like our 4 stroke engines?  One stroke in 4 is burning fuel. Do you think the pistons would melt if all 4 strokes generated the same heat?

Doing that would slow down the power delivery.  And comparing the physics of electrical power to combustion/ convective heat flow are not exactly apples to apples.

Lithium titanate batteries can charge (and discharge) very, very fast but you won't go very far.  We considered them for a possible autocross car with like 10 minutes running time.

The public has spoken... we don't like Ohms law, so we'll just repeal it. If enough people say it will work, it must be true. No reason to let facts get in the way of they said.

Funny that this comes up right when millions of folks are without power. We need to put a ban on all storms in the future also.

Maybe Dr. Fronk-in-stine. can show us how to charge them from lightning?

Pulsing is a pretty common trick for applying large amounts of power without overheating components.  Most LEDs are pulsed at a higher current than they can handle at a steady state and I've seen capacitors in a research facility charged in stages to avoid overheating.  I don't know if any of the current (no pun intended) car charging systems use a pulse system but I've seen several research papers proposing just that.

If the power is out and you can't charge your EV, the filling pumps at the gas station don't work either. EVs and ICEs can both be stranded by a power outage.

A home backup generator seems like an easy enough way to prevent being stranded with a dead EV.
