Reply to comment by [deleted] in South Korean researchers say they have developed an anode-free lithium-ion battery that is 40% more energy dense than existing batteries and will enable EVs to travel 630km (390 miles) on a single charge. by lughnasadh

It's not a shit unit. It just isn't a SI unit. kWh are cool so you can relate it to an hour. If you charge something with 500W you know it has 0.5kWh after an hour. Just like km/h is used instead of m/s

WTH is your strawman here. Please try to understand what i wrote instead of arguing against something i did not say. I did not say anything about vehicles. I agree that in the case of cars and their batteries kWh related to their distance they might be able to travel, kWh does not make sense. But charging money by the kWh is common. So if you charge your 1kWh car battery (or whatever) you know a 1kW supply needs 1hour to fill the battery. And I know how to convert units.
