In the medium term, there seems to be opportunity for increases in charging speed as well. Tesla just announced v3 supercharging, which hits 1000 miles/hour and 75 miles of range in 5 minutes, and at the very least larger batteries will stretch that number. It's not clear how far they and others can push high-speed charging, but batteries are only going to get better.
