Dynamic Load Balancing on EV Chargers.

In recent years, with the rapid growth of the number of EVs and the continuous increase in electricity demand, the increasing electricity load will be a significant challenge for the power grid infrastructure in countries around the world. On the one hand, countries around the world are increasing their efforts to build power infrastructure, especially smart grids; on the other hand, it is a consensus among all parties that EV chargers need to have the function of dynamic load balancing to protect electricity safety.

It is well known that the electricity consumption in European households has the following characteristics:

- Electricity load fluctuates greatly, with significant peak and valley differences.
- The capacity of the grid is limited, making it difficult to meet the demand for high-power charging pile access.
- The application of distributed energy sources such as photovoltaic power generation is becoming more popular, increasing the complexity of the grid.

Dynamic Load Management (DLM) plays a significant role. Dynamic Load Management on an EV charger is a smart feature that automatically adjusts the charging power of EV based on the available power capacity in home or business. This ensures that electric vehicles are charged safely and efficiently without overloading circuits or exceeding capacity limits.

RAEDIAN has introduced three series of smart EV chargers that comply with EU standards and TUV certification, perfectly addressing the needs of different customers and scenarios. For example, when charging at home, real-time monitoring of the total power load and household electricity consumption is conducted, and the power for EV charging is adjusted under the premise of ensuring safety margins. In the case of photovoltaic power generation, priority is given to self-use, which is the most economical way of using electricity and reduces the impact on the grid. When charging in office areas or destinations, power safety monitoring of the station is achieved through the networking of multiple machines and matching CMS.

The dynamic load balancing function recommended by RAEDIAN brings value to customers:

1 Cost savings on capacity expansion
   For households, charging piles are high-power appliances, and installing charging piles undoubtedly poses a challenge to limited household capacity. However, in addition to incurring expensive expansion costs, permits from relevant agencies may also be required. DLM can save costs by monitoring the load on the circuit and ensuring that the power consumed by EVs does not exceed the safe value, thereby avoiding waste caused by expansion.

2 Avoiding circuit overload
   Daily household electricity consumption changes in real time, and when multiple high-power appliances are operating simultaneously, tripping may occur. The task of DLM is to intelligently allocate the remaining available electricity capacity in the household to the EV chargers, ensuring that household electricity consumption and vehicle charging can proceed simultaneously without causing circuit overload, greatly improving safety and charging efficiency.

3 Cooperating with RAEDIAN's CMS system to manage charging piles for customers.
   Under the premise of limited power capacity, define and configure charging priorities independently, and charge flexibly. DLM also plays a significant role in the public charging field. When multiple EVs are charging simultaneously, it automatically balances the distribution of available power between vehicles. Of course, DLM can also be combined with charging queue systems to concentrate power on vehicles with higher priorities, slowing down the charging speed of other vehicles. Therefore, charging station operators can set their own charging rules, making charging piles more user-friendly and flexible in serving vehicle owners.
