As the demand for electric vehicles grows, EV user’s requirement for higher power fast EV chargers is rising. As EV charger manufacturers respond with new high power super chargers, energy demand for such charging stations at peak demand is becoming an increasing challenge for the grid. Energy Storage Systems (ESS) offer a sustainable solution. Energy storage Systems harness grid power and other sources of sustainable energy to store energy at the most advantageous tariffs and deliver it on demand. Energy Storage Systems mitigate power networks, balance local energy needs, and can supply energy back to the grid during peak hours, reducing costs through energy arbitrage.
