I see Energica is claiming they've got bikes which can do 400km, and a "quick charge" back to 80% in 42 minutes.
Not me. Imagine getting to the recharge spot moments after someone else and having to wait for them before you can start. 42 minutes becomes 84. Stuff that. They would need way more charging outlets than potential customers.
Someone mentioned prebooking. Stuff that too. I don't want to be constrained by a booking. My stress would go through the roof if I was running late.

I really wonder how densely populated areas will get by in this regard. Not so bad where larger properties can put in their own charging capabilities but I’m picturing all the cars in London attached to extension cords out the window of the terraced house. One charging station per block won’t cut it.

@crucial we might end up with charging stations on the footpath like the old parking metres? Or a charging point in the ground that you connect up to when you park up for the night? Which ever way it goes it's going to take a bit of work.

Have seen a few companies in Europe integrating with lighting infrastructure etc

My concern is that rolling out charging infrastructure becomes a closed cycle i.e. because we have built the infrastructure we commit long term to EV. Whereas I think hydrogen is the way forward, much cleaner and needs no costly infrastructure.
For those old enough a bit like VHS V Betamax. The inferior system won out because it became ubiquitous. Car manufacturers now have a vested industry in the EV industry despite it being relatively inefficient and environmentally suspect.
-
@dogmeat EV charging infrastructure is pretty cheap though. You can buy a 2-gun charger that will charge a bus in 40 minutes (if you ramp it right the fuck up) for less than $50k. When you consider the bus costs upwards of 12 times that per unit...

So if porn selects EV over hydrogen, that will be the key difference?

I think there is room for both in a petrol / diesel sort of manner. Electric is killing it at the moment & I've read / heard little of hydrogen technology of late honestly.

Hydrogen will dominate the large transport sector.

The other factor: electricity is already everywhere. Just need to put the right spout on it to feed your vehicle.
Hydrogen will have uses no doubt BUT they'll be highly specialised. Creating hydrogen for transport is easy enough, but they're well behind the game when it comes to a distribution network.

the big advantages of electricity is it's simplicity (for the vehicle) and the ubiquity of the grid. Recharging will become a thing I reckon - with chargers just proliferating along with electric vehicles.
Don't underestimate the headaches with storing and transferring hydrogen either - and having to make the bloody stuff in the first place! It's a super important alternative fuel, but I can't see it displacing electrical for most vehicles.

Yeah this is my concern too. How often would you be charging right up until you leave? So that makes the length you've got left even shorter, plus it's not like you're gonna go right up to the limit, so bring that 4 hours closer to 3....then you gotta wait your turn to charge 20 mins to take you SFA further...

Batteries simply don't work for interstate b-doubles, ships and planes. They're too heavy. That's not to diminish the challenges of storage which are orders of magnitude more difficult than LPG.

In addition to what @voodoo says above: electric bikes are probably always going to cap out at a certain charging rate simply because the hardware for fast charging adds weight and complexity to the electrical systems - need more wires, more thermal management etc.
Fascinated by that. You would have thought the thermal management components would be quite light and the thicker conductors would only add a few pounds. Is it the battery construction itself which adds all the weight?

Should have clarified: the thermal management of the battery itself. Having liquid cooling is the only way to guarantee you can get the battery to the optimum fast-charge temperatures in any condition.
You can do that on a motorcycle but the scales of construction don't work as well, because you simply have mass restrictions - also centre of gravity issues on a bike versus a car.

@majorrage said in Electric Vehicles:
I’ve always thought battery change was the way forward, not charge.
For trucks / hauling the torque of electricity makes huge sense, but surely the battery weight / size is a hinderance?
Energy density remains a critical factor - always improving of course, but there is a reason a lot of the big boys (Daimler, Volvo, Scania) are looking at this in addition to Tesla; they see a future.
Need to ensure a truck is going to be able to do the legal hours specified to the driver's satisfaction, and more importantly that the charging infrastructure is up to smashing a load of kWh into a battery in the shortest time possible - often in the middle of fucking nowhere.
Battery change could be an avenue there, but downtime is the issue on any given journey. Overall downtime on an electric truck for maintenance is quite small compared to a diesel due to simplicity by contrast.
I think we'll probably see a lot of electric in short haul/light commercial and public transport - you don't need more than 400km a day which is a single charge for a lot of the proposed vehicles. BYD in China has looked to move solely into that market and make Big Rigs tomorrow's problem.

@nta I went to BYD's factory in China about 10 years ago. Was hosted by a Spanish solar developer as their financial advisor , along with a group of international banks they were trying to get comfortable with BYD's PV technology.
Got to drive their EV around the facility, and the PV manufacturing was 1st rate.
But by far the more impressive setup was their battery manufacturing facility. Looking back now, you can see they'd identified it as the main game.
If only I'd been smart enough to take notice 😎

Hybrid long haul trucks make perfect sense. Large torque to enable them to easily accelerate from rest, diesel for economy, range and charging while in transit.
