In addition to EFI Automotive, the Korean Evar has also unveiled a robot that plugs itself into a socket on a pillar where the chargers are connected. The robot is also autonomous but the concept goes further. Indeed, with a battery charger, it is possible to recharge several cars at the same time, because the electricity passes from one car to another. Supported by Samsung, the start-up has already sold some 20,000 chargers in Korea. Among the other chargers manufacturers, many companies, such as Samsung or SK, have unveiled compact and light chargers for EVs for home.
