Electric bus fleets are groups of buses powered by electricity instead of traditional fossil fuels. These buses use large batteries to store energy, which helps reduce air pollution and greenhouse gas emissions. Many cities are adopting electric bus fleets to promote cleaner public transportation and improve urban air quality. Charging infrastructure is essential for maintaining electric bus fleets. Buses need to be charged regularly, often at depots or designated charging stations. As technology advances, electric buses are becoming more efficient, with longer ranges and faster charging times, making them a viable option for public transit systems worldwide.
