AC slow chargers (for overnight or at work) are cheap and simple. Basically the same as installing an outlet for a clothes dryer or oven with a circuitry box to act as a relay and monitor. DC fast chargers are more complex and expensive but still way cheaper than a robotic mechanical battery swap system that works across multiple makes and models of car. And more of these are being installed literally every day: Tesla: https://supercharge.info https://supercharge.info Others (US): https://fastcharger.info https://fastcharger.info We're getting to the point where many newer EVs are coming with 300+ miles of range that can do an 80% charge in 20 minutes. The swappable batteries seems like a great solution for mopeds etc. but for giant car batteries I think better and cheaper batteries will outpace any advantages that battery swapping has within a few years.
