Load Balancing is a technical strategy for rationally distributing limited power resources among multiple charging points. Compared to the specifically mentioned “Dynamic Load Balancing,” this is a broader concept covering everything from static current limiting to dynamic adjustment, aimed at preventing electrical overloads and ensuring infrastructure operates safely within existing grid capacity.

Analysis from an Application Environment Perspective

Load Balancing is primarily applied in scenarios where power capacity is a scarce resource.

• Office Buildings & Campuses:
  When an office building installs 20 chargers, but the building transformer can only support 10 running at full speed, the load balancing system intervenes. It distributes power evenly or rotates charging sessions (e.g., 15 minutes per group). In this environment, it avoids expensive infrastructure upgrade costs.
• Multi-Level Parking Garages:
  In multi-story structures, cabling distances are long, leading to voltage drops. Load balancing monitors not just power distribution but voltage levels across floors. When many vehicles plug in on the same floor, the system automatically limits current to prevent local wiring from overheating and causing fire hazards.
