How Dynamic Load Management saves your money
In recent years, with the rapid growth in the number of electric vehicles (EVs) and the increasing electricity demand they bring, it poses a significant challenge to the power grid infrastructure in countries around the world. On one hand, countries worldwide are intensifying their efforts in developing power infrastructure, particularly the construction of smart grids. On the other hand, charging stations need to have the capability of Dynamic Load Balancing, and ensuring electrical safety has become a consensus among all parties involved.
European households primarily encounter the following issues regarding electricity consumption:
- Electricity consumption exhibits significant fluctuations and noticeable peak-to-off-peak differences.
- The capacity of the power grid is limited, making it challenging to meet the demand for high-power charging stations.
- More adoption of distributed energy sources, such as solar photovoltaic (PV) systems, increases the complexity to the power grid.
Dynamic Load Management (DLM) has played a significant role in ensuring the safe and efficient charging of electric vehicles (EVs), without overloading circuits or exceeding capacity limits. Dynamic load Management on an EV charger is a smart feature that automatically adjusts the charging power of your electric vehicle (EV) based on the available power capacity in your home or business.
RAEDIAN has introduced three major series of intelligent charging stations, NEO, NORA and NEX, that comply with EU standards and have TUV certification. These charging stations effectively address the diverse needs of different customers and scenarios:
Home charging: It’ll monitor real-time power load and household electricity consumption, adjusting the charging power for EV cars while ensuring safety margins.
Solar charging: In the presence of solar photovoltaic (PV) generation, the charging stations prioritize self-consumption, maximizing cost-effectiveness while minimizing impact on the grid.
Semi public charging: the stations utilize multi-unit networking with NEX products and a compatible CMS system (Charging Management System) to enable power safety monitoring at the charging station.
The dynamic load balancing (DLM) feature recommended by RAEDIAN can bring several benefits to customers:
- Cost Savings on Capacity Expansion: Installing charging stations in homes can be challenging due to the high power demand, which may exceed the existing electrical capacity. However, instead of costly capacity expansion, which may require permits and approvals, DLM can monitor the load on the circuit and ensure that the power consumed by EVs does not exceed safe limits. This helps save costs and avoids wasteful capacity expansion.
- Prevention of Circuit Overload: Daily household electricity consumption varies in real-time, and when multiple high-power appliances operate simultaneously, circuit breakers can trip. DLM intelligently allocates the available electrical capacity to the charging station, ensuring that household electricity usage and vehicle charging can occur simultaneously without causing circuit overload. This greatly enhances safety and charging efficiency.
- Integration with RAEDIAN’s CMS System for Charging Station Management: In the context of limited electrical capacity, DLM allows customers to define and configure charging priorities, enabling flexible charging. DLM also plays a significant role in the public charging domain. When multiple EVs are charging simultaneously, it automatically balances the distribution of available power among the vehicles. Additionally, when combined with a charging queue system, DLM can concentrate power on vehicles with higher priority, slowing down charging for other vehicles. This empowers charging station operators to set their own charging rules, making charging stations more user-friendly and flexible in serving vehicle owners.
