As more and more electric cars appear in homes, condominiums, and businesses, it is becoming increasingly important to ensure that charging cars does not overload the electrical grid. Load balancing , also known as dynamic load control , helps with this.
What does it mean exactly?
Load balancing is a feature that monitors the overall power consumption of a given building and adjusts the power of the EV charger(s) accordingly. The goal is to ensure that charging does not exceed the capacity of the grid or the main fuse.
How does it work?
A sensor or energy management module monitors how much energy the household or building is currently using (e.g., whether the oven, air conditioner, washing machine are running). If there is little free capacity available, the EV charger automatically reduces the charging power – for example, charging at only 3 kW instead of 11 kW. If other consumers stop, the charger regains the higher power.
Why is it important?
- Overload and fuse tripping can be avoided
- No need for expensive network expansion
- Multiple EV chargers can operate in parallel – for example in an apartment building or a company parking lot
- Can also be used with solar systems
What types are there?
-
Static load balancing : regulates based on a predefined power limit
Dynamic load control : responds based on real-time consumption monitoring
