Designed specifically for group vehicles such as buses, logistics vehicles, and taxis, it is a core infrastructure for operational electrification. Typically, centralized, dedicated charging stations are built, employing high-power DC fast charging or customized solutions (such as rooftop charging for buses). The core requirements are reliability, efficiency, and low cost. This necessitates the use of intelligent scheduling and energy management platforms to utilize off-peak electricity for orderly charging, and considers future V2G (vehicle-to-grid) potential to maximize operational efficiency.
