With the world quickly adopting electric vehicles, managing their effect on our power grids is essential. If you're looking to install multiple charging stations, you may have heard the terms "local load management" or "charge management system". With the increase in the number of people using electric vehicles, it is important to ensure that our electrical supply systems are capable of accommodating this eco-friendly transformation.
What is Load Management?
Load management refers to balancing the demand that EVs create on the grid with the available supply of power. Load management reduces energy usage during peak demand periods, reducing the burden on the grid. At the same time, it optimizes EV charging. When multiple charge points are in use, it balances the energy among them to ensure that vehicles can be charged in the way that best serves the driver or business.
How does EV charging load balancing work?
Load balancing systems instruct EV chargers to deliver the right amount of energy. EV charging load balancing instructs the chargers to deliver the right amount of energy and manages the energy flow. It is critical in an EV fleet environment, as it must manage the volume and power demands of vehicles coming through.
EV charging load management software constantly communicates with the electricity infrastructure, charge points, and charging EVs.
EV charging load balancing can be static (based on the time or day) or dynamic.
Static Load Management & Dynamic Load Management
Static Load Management is a technique used in EV charging to guarantee that the aggregated power consumption does not surpass the maximum capacity of the electrical connection serving the charging infrastructure.
Unlike static load management, which responds to individual demand, dynamic load management responds to real-time demand by adjusting the power allocated to each charging station. For example, when a second EV is plugged into an EV charger, automatic changes are made to address the amount of electricity used through load sharing.
