– Why do electric devices with batteries (phones, electric cars, …) can only be charged by one charger at a time?

465 views

Hi, with all the boom of “fast charging” I’ve been wondering why can’t we have phones or electric cars with twice or more the charging ports. I understand that is inconvenient to plug two chargers instead of one but wouldn’t that increase the charging rate, solving one of the problems with electric cars (refueling gas is way faster). As this is not the case there should be a good reason why it is not feasible, what is it ?

(I did not find anything close to convincing in google).

Cant say something sensible other than: they’re all one circuit. And there are probably reasons why it’s hard to make it into several modular circuits for multiple chargers. Plus, the heat. Charging creates massive heat, that’s why some cars use liquid cooling on their battery packs. That needs to dissipate somewhere too, without your phone becoming too hot to handle…?
