QST EV Static Load Balance: Optimizing Electric Vehicle Charging Efficiency
In an era where electric vehicles (EVs) are increasingly becoming a common mode of transportation, ensuring efficient and sustainable charging solutions is paramount. One innovative approach to achieving this is through the implementation of Static Load Balance—a smart charging feature designed to optimize the distribution of available power among multiple chargers located at a single charging site.

Static Load Balance enables facility managers to set a maximum power threshold for multiple chargers within an integrated management system. This system intelligently redistributes charging power among active chargers to ensure an equitable distribution. The primary objective is to protect the local power grid from exceeding capacity limits, particularly during peak hours of electricity consumption.
Under this framework, when the first EV connects to a charger, it receives the maximum available current, which might be, for instance, 32A in a given parking lot scenario. However, as additional EVs begin to charge simultaneously, the Static Load Balance system seamlessly redistributes the available power. Consequently, all active chargers receive a proportional share of the total power, thus maintaining a stable load on the local grid.

This innovative approach not only enhances the efficiency of the charging process but also protects infrastructure from potential overloads. By facilitating maximum power delivery when fewer EVs are connected while ensuring fairness as demand increases, Static Load Balance emerges as a crucial feature in the realm of electric vehicle charging solutions, aligning with both sustainability goals and grid stability.
