KAIST announced on January 5 that it recently embarked on the ‘low-cost wireless charging electric bus commercialization project’ as part of the national project of the Korea Agency for Infrastructure Technology Advancement under the Ministry of Land, Infrastructure and Transport. It is planning to put them on bus routes as commercial vehicles by the end of this year. Daewoo Bus, LS Cable & System, Korea Electric Vehicle Service as well as Dongwon OLEV, which has the online charging technology, will participate in this project.
Electric wires will be buried underneath the road to create a magnetic field, and receive magnetic force from this vehicle wirelessly and convert it into electricity, and this electric bus will use this electricity as a power source. Unlike ordinary electric vehicles that must stop by charging stations, it is capable of real-time charging while it is stopped for transfer, etc. For this reason, it can use only 20% of the existing electric bus battery capacity to run the same distance. As the battery gets smaller, the cost can be reduced and it weighs less, thereby greatly improving operating efficiency. KAIST recently decided to raise the charging efficiency from 70% to 85% for the project by enhancing the technology.
