Dynamic Load Balancing (DLB)
Core Definition
Dynamic Load Balancing is an intelligent power management technology that monitors the total power load of a building or site in real-time and dynamically distributes the remaining available capacity to active chargers. It ensures maximized charging efficiency without tripping the main breaker or requiring expensive grid connection upgrades.
Analysis from an Application Environment Perspective
DLB is the antidote to “power capacity anxiety,” primarily applied in older buildings with limited power resources or high-density charging scenarios.
- Residential Retrofit:
In many apartments built decades ago, transformer capacity did not account for EV loads. DLB monitors real-time building consumption (e.g., during evening peaks when cooking or using AC) and throttles down chargers; late at night when usage drops, it automatically ramps up charging power. This makes installing chargers feasible without upgrading transformers. - Corporate & Logistics Depots:
When dozens of vehicles plug in simultaneously, uncontrolled charging would crash the local grid. The DLB system acts as a traffic controller, prioritizing high current to vehicles based on State of Charge (SoC) or departure time, while queuing or limiting others, ensuring safe electrical operations at the site.
