Hahaha! No, it may not.

Hahaha! No, it may not.

This new battery should have more capacity than current battery packs, but let's take the 100kWh pack from Tesla's model S as example: 100kWh means it would require at least 100kW if it was to be charged in one hour. For one minute that would be 6000kW or shorter 6MW.

Please show me the cable for 15kA or the power plant providing that power. Marketing BS...

I don't want to even think about the cable diameter. Or trying tot pick it up.

Are they planning on pushing 35KV through that charging cable? Pics or it didn't happen!

At that level we're talking busbars!

I do actually wonder if we may one day need to get to some kind of heavy duty fork for charging, perhaps with no moving cable involved. But even then the power and current necessary for the marketing dream above are insane...

I think the only viable way to do this would be to have a buffer battery/capacitor at the charge points that can dump all the energy into the car battery on demand. The buffer can then recharge at a reduced rate that the local grid can cope with.
Regardless, as you say, these numbers are insane and scary.

Thought I'd resurrect this post as this new article is relevent...

Oliver Hamilton ah yes, I saw the headline, but haven't seen any hard numbers yet. We will need a much better charging infrastructure and possibly other, additional charging methods, be it through fuel cells or solar panels. But let's wait for some numbers, shouldn't take too long.
