I've used 50kW chargers quite a bit, and they do offer a noticeable speed boost compared to 22kW chargers. For my EV, a 50kW charger usually gets me from 20% to 80% in about 30-40 minutes, which is quite efficient for a quick stop. In contrast, a 22kW charger would take closer to a couple of hours. As for availability, in my experience, they're generally more common along highways and in urban areas because they're suited for drivers who need a quicker charge during longer trips.
Regarding compatibility, I've noticed that while most newer EVs handle 50kW charging just fine, some older models might experience reduced efficiency or charging rates due to limitations in their battery technology. As for cost, 50kW chargers tend to be more expensive to use than slower options, but the convenience often justifies the price for me during road trips.
Anyone else noticed differences in charging speeds or costs between regions?
