There really needs to be a common, open standard for EV charging, it's honestly one of the biggest things holding back higher adoption. The worst part is that there is one, but the most popular vehicle refuses to implement it because they have control over a huge proprietary network.
Imagine if there was "Ford gas" and "Honda gas", and even though they were the same fuel, you couldn't fit the fill nozzle into your car with the other one. That would be absolutely insane.
People hate thinking about dongles and connectors, it just needs to work.
