Electric vehicles will take over the world, but before they do this, they need to convince a lot of people they are a viable alternative to ICE cars. One of the biggest issues is range anxiety and EV makers have offered several solutions to the problem. One of them is installing bigger batteries to improve the range, with all the downsides that derive from this. Among them are the high costs, but also the higher weight and the lower efficiency that comes with it.
Another way is to shorten the charging time, which will effectively allow an EV owner to spend less time at the charger. If this time is low enough, an EV could be charged pretty much the same way as an ICE is refueled, in a couple of minutes. This makes the range less important, as long as

the density of fast DC charging stations is high enough to not worry about running out of battery. It turns out that most EV makers have chosen this path or a combination of both.
Reducing the charging time is considered the holy grail of EVs and scientists are scrambling to get there using different technologies. The perspective of having your EV topped up in the time it takes the driver to drink one coffee is enticing enough. Scientists have tried lowering the charging time by improving battery technology or by adopting quantum charging. These are still years in the making, so don’t expect an EV to benefit anytime soon.
