The South Korean island Jeju-do wants to become carbon-free by 2030. Last month, a city on the island introduced their first electric buses for public transport. The vehicles use a a special technology that was made in Korea. Instead of charging the batteries on the bus, an empty battery is exchanged at a bus stop within 1 minute.
I wrote an article about that technology and the new buses on my website Kojects: Jeju introduces Electric Buses with Swapping Battery – Kojects
I wonder what the members of this community think about this technology and the system. I assume that the idea is born out of the constraints that batteries have but lately, the performance and storage power of batteries improved immensely. So, is this kind of technology still useful?
