Tesla To Demo Electric Car Battery-Swapping

One of the key features of Tesla’s electric cars hasn’t been seen yet–but that’s about to change with a demonstration of the battery swap-out tech.

Tesla’s CEO Elon Musk announced via Twitter that his range of electric cars will get its first battery-swap demonstration this Thursday, June 20th at 8 p.m. in California.

One issue with electric cars is that, due to the hard physics and chemistry of battery design, batteries can’t be recharged very quickly. This means that while a car that runs on gas can pull into a gas station, fill up with fuel, and drive off in mere moments, an electric car takes hours for a full charge and a much longer interval for a quick top-up charge.

Tesla’s solution to this is an automated device that can slide out a drained battery from a car and swap it for a fully charged one. It’s not been seen yet, due to technical difficulties.
