So where are those cars parked when not being driven, and why could they not be charged there? (Not meaning to shoot @wyx087 - only electrifying London)the electrifying London Fully Charged podcast episode said in London about a third of vehicles would still need to rely on petrol station model
Exactly, somewhere in the UK every car is parked up for at least a few hours every day.
No, because they are targeting a product to go on sale in 2025 which can achieve a 240kw charge rate (for five minutes). Tesla and Porsche can already do this (with the same caveats - this product needs to get the battery to 60C to achieve that rate, so the preconditioning may take longer than the charging).Is this the gamechanger we are all waiting for?
Electric car batteries with five-minute charging times produced
Could be achieved by front-loading some storage mechanism. Could be a battery array or some advanced super-capacitor that is fed with a continuous 250 kW current but can deliver spikes of 500 kW or maybe one mW for trucks. Instead of using cables, I think induction charger could be a better option to better cope with the heat and to avoid having to use unwieldy cables.Brilliant look into the future however.....:
"The batteries can be fully charged in five minutes but this would require much higher-powered chargers than used today. Using available charging infrastructure, StoreDot is aiming to deliver 100 miles of charge to a car battery in five minutes in 2025."
First someone will need to rework the whole existing charging network and secondly how the UK power grid will cope with this huge surge?
Can anyone with knowledge to shed a light please?
Induction charging is much more inefficient and slower than a physical cable, they would need to improve induction charging before that became a viable 'quickcharge' optionCould be achieved by front-loading some storage mechanism.

I am intrigued by the 'we' in the first sentence. Would you say a bit more?For the next generation of Formula E (Gen3), we are making small boost chargers (basically small batteries) to do around 600kW for a 30 second pitstop. It will only be around 10% ish of the capacity of the car's battery, but should be interesting to see where it goes.
As for boost batteries for chargers, you can remove some of the need for weight and space (within reason), so super caps could be more relevant due to their high cycling lifetime and peak load capacity. Just that their kWh/m3 is around 10-20 times worse than a lithium-based cell, so would need a fair amount of space.
