Electric car batteries with five-minute charging times produced – first factory production means recharging could soon be as fast as filling up petrol or diesel vehicles

Can someone with a clue comment this? I work developing electrical cars but I’m a safety guy and this is outside of my expertise.

The article says it can charge 100miles in 5 minutes (which is clearly longer than filling up petrol and also longer than the headline makes you believe – it sounds like you can charge from empty to full in 5 minutes). 100 miles should be about 20kWh. To charge this in 5 minutes means a charging power of 240kW. Probably significantly more because of power loss at the charging process. This seems great but not like a game changer, since afaik Tesla supercharger can charge with 250kW already (but I’m not sure if this is already used in current models or is only a potential for future developments). I assume the 100miles in 5minutes are in the perfect situation (meaning loading from 30% to 60% at perfect battery temperature, for example) and will take significantly longer in less perfect situations.

So many questions.
