Interesting. None of the claimed improvements are based on radical new technology, so my credulity isn't stretched. The energy density improvement to 240 Wh/kg is useful and in line with broad technology predictions.

What's the dry-to-full charge time on electrics these days?

Depends how big the battery pack is. If you are charging a 100 kWh pack from a 175kW charger then maybe under an your. The charge rate profile means it will charge at less than full rate when empty and when approaching full. The best region is 50% to 85%, which could take you just 12 minutes. When there are enough fast charge points you should never choose to run your battery dry.
There's an interesting metric for charging EVs which is MPH, miles of range per hour of charge. An efficient car that does 4 miles per kWh would have a peak MPH of 700!

All a bit academic with the current state of the charge network.
