I always found it strange that we have a very developed petrol infrastructure, but not electric charging. Petrol needs to be shipped, first from drilling site to refinery, then distributed around the country, stored in underground tanks, protected against fire, kept topped up as supply/demand fluctuates, and even then you are probably never further than 10 miles from the nearest petrol station. Whereas electricity is, well, everywhere. Every petrol station has an electric connection. It doesn't need to be stored on site, transport is easy (hard for the grid but easy for the end user), no unusual hazards, etc. Of course charging is slower, and I guess that's the real bottleneck, but even then. We put holes filled with petrol all over the country, but can't put extra sockets.

> Every petrol station has an electric connection. It's not as simple as using what's there. For fast chargers you also need to install a high power grid connection. However, battery based chargers are an interesting option for low installation costs without a high power connection while still achieving 120+ kW charging. The battery can either be integrated into the charger unit itself for the lowest installation cost or a large battery pack can be placed on site to run the chargers off: https://www.cnet.com/roadshow/news/vw-group-components-e-on-battery-ev-charger-germany/ https://www.cnet.com/roadshow/news/vw-group-components-e-on-... https://freewiretech.com/products/dc-boost-charger/ https://freewiretech.com/products/dc-boost-charger/ https://www.greencarreports.com/news/1129240_battery-boosted-charger-a-model-for-filling-in-fast-charging-gaps https://www.greencarreports.com/news/1129240_battery-boosted... https://thedriven.io/2020/05/07/new-goulburn-battery-beats-grid-upgrade-for-electric-vehicle-ultra-rapid-charging/ https://thedriven.io/2020/05/07/new-goulburn-battery-beats-g... As battery prices continue to fall these types of charger configurations will become more attractive.
