What is Load Balancing?
Load balancing is a crucial aspect of charging electric vehicles. In simple terms, it means evenly distributing the power in a property, allowing multiple devices to run simultaneously without triggering any fuses.
This ensures that the power output in a property is optimized and, ultimately, an improved electricity usage might save you money.
How Does Load Balancing Work?
The basic idea behind load balancing is to split available power among different devices. Instead of running all devices at full power for a short time, load balancing makes them operate at lower power levels for a longer time. This prevents the risk of triggering fuses and optimizes the property's power usage.
While many charging station manufacturers offer load balancing to their customers, the feature itself can vary.
This can cause confusion, as the different versions of load balancing share the same name. At Perific we suggest breaking it down into two types of load balancing:
Static Load Balancing
Dynamic Load Balancing
What is Static Load Balancing?
Static load balancing specifically deals with distributing available power between one or more EV charging stations.
This type of load balancing does not consider the total power usage in the property but instead balances solely against a specified power level. This solution is, in other words, 'blind' to what is going on within the property.
How much power that is distributed to the charging station is determined by the size of the main fuse and the estimated available power capacity.
It can be considered a simple form of load balancing, since it can only estimate how much power is available.
Underutilization of available power
Static load balancing may not use the available power optimally, as it does not consider the overall power consumption in the property. For example, it might take longer than necessary to charge your car.
On the other hand, it can also result in unnecessary electricity costs, since there is still a risk of power peaks during charging, limited only by the main fuse's maximum power level.
Advantages of static load balancing:
• Protects the fuses
What is Dynamic Load Balancing?
Dynamic load balancing, unlike static load balancing, considers the power usage in the entire property in real-time when calculating available power for EV charging. This means that one or more chargers continuously receive information about the property's power consumption in relation to the main fuse size, ensuring that EV charging always takes the entire property's electricity consumption into account.
When multiple devices, such as the oven, the heat pump, etc., are active simultaneously, dynamic load balancing regulates the EV charging to a lower power level. But when capacity is freed up, for example by turning off the stove, dynamic load balancing increases the EV charging to a higher power level.
This decreases the chance of power peaks, ensuring consistently distributed power throughout the day. With dynamic load balancing, therefore, you optimize your power usage, making it possible to reduce electricity costs and still have a fully charged car.
Dynamic load balancing is crucial for EV charging
With dynamic load balancing, you ensure that the power usage in the property is optimized. This not only contributes to a more stable power grid and, ultimately, a greener world but also means potential savings on lower electricity costs.
For the owner of an EV, dynamic load balancing is crucial for an efficient charging experience.
Advantages of dynamic load balancing:
• Protects the fuses
• Calculates available power in real-time
• Utilizes available power optimally
Perific is the obvious solution for dynamic load balancing
Perific's dynamic load balancing is suitable for all types of installations related to EV charging, aiming to optimize the power usage in all properties.
By monitoring the property's power usage in real-time, Perific communicates the available power to the EV charging station, thus optimizing the power usage.
