Dynamic Load Balancing (DLB)

Dynamic Load Balancing (DLB) is a technology used in electric vehicle (EV) charging systems to manage and distribute the electrical load dynamically across various devices and systems in a household or facility. This helps prevent overloading the electrical network by adjusting the power distribution based on real-time demand.

When charging an electric vehicle at home, the process can significantly increase the demand on the household’s electrical system, often consuming more than half of the average capacity. Other high-energy appliances, like electric ovens or heat pumps, further exacerbate the risk of overloading, which can lead to power outages. Dynamic Load Balancing mitigates this risk by continuously monitoring the total electricity consumption in real-time. 

The DLB system measures the power usage every second and dynamically adjusts the power allocated to the EV charger. If the household appliances are drawing a high amount of power, the DLB system reduces the power supplied to the EV charger, slowing down the charging process to avoid tripping the circuit breakers. Conversely, if the overall power consumption in the household is low, the DLB system can increase the power directed to the EV charger, speeding up the charging process. This technology ensures a stable and efficient power distribution, allowing multiple devices to operate simultaneously without overloading the system. This is similar to Dynamic Load Management (DLM), but DLM is applied on a larger scale, such as in commercial properties or public charging stations. 

In setups with solar panels, DLB can optimise the use of solar-generated electricity for charging the EV, switching to grid power only when necessary. For homes or businesses with multiple EVs, DLB can prioritise the charging of different vehicles based on set preferences, ensuring that the most urgently needed vehicle is charged first. This system maximises the efficiency and safety of home EV charging, enhancing the overall user experience and energy management. Unlike DLM, which often involves integrating with smart energy meters and managing a larger scale of energy distribution, DLB is typically simpler and more suited for individual households.
