EV Charging Energy Storage System (EV-ESS)

As the number of electric vehicles (EVs) continues to grow rapidly, the increasing power demand from charging stations places tremendous stress on the electrical grid.
By integrating energy storage systems with EV chargers, electricity can be stored first and released later, effectively reducing instantaneous grid impact.
The system also allows charging during off-peak, low-tariff periods and discharging during peak hours, achieving optimal cost efficiency.

In addition, EV-ESS supports fast-charging operations, delivering a faster, more stable, and reliable charging experience for drivers while contributing to smart mobility development and low-carbon urban transformation.

Key Functions

           l Reduced Grid Impact
             During fast-charging, the instantaneous power demand is extremely high.
             Directly drawing from the grid may cause voltage drops or exceed contracted demand.
             The integrated energy storage system supplements the power supply, easing grid stress.

           l Electricity Cost Optimization
             Stores energy during low-tariff (off-peak) periods and discharges during high-tariff (peak) hours to power EVs or charging loads, reducing total electricity expenses.

           l Backup Power Supply
             Acts as an emergency power source during grid outages, ensuring continuous charging service and system operation.
