Dynamic Load Management (2000 x 2000).jpg

Dynamic Load Management for EV Charging

The drive to reduce our carbon footprint has caused many consumers and fleet owners to purchase electric vehicles. To increase the utilization rate of these vehicles, more charging stations are being built at the workplace and in commonly visited locations. The need to balance facility loads from local electric utilities and other power sources is a key to making EV Charging reliable and profitable. WAGO’s Dynamic Load Management provides intelligent control of your charging stations by avoiding the risk of grid overloads and expensive peaks. It also ensures grid stability, even if multiple charging stations are in use along with normal operating systems.

Maximizing Charging Infrastructure Utilization

Demand- and Supply-side Management:

WAGO’s Dynamic Load Management can help reduce costs for both demand- and supply-side energy management. They can either be implemented independently or in parallel with each other. Both approaches reduce the energy demand at the grid connection point, allowing for peak shaving.

Demand-Side Management: The goal is to decrease demand by reducing energy consumption to prevent usage spikes and using WAGO’s Dynamic Load Management system can dramatically limit the power allocated to EV charging based on the number of vehicles and the time of day.

Supply-Side Management: With WAGO’s Dynamic Load Management, configure the system to utilize local power sources (i.e. photovoltaic systems, battery storage, etc.) during peak hours to reduce high-demand electricity charges from the utility company
