About Charging, Load, and Energy Management
Distinguishing between the different systems
An electric energy management system controls and monitors an energy system and its components, taking into account both energy consumers and producers. This includes managing both electrical consumption and generation, such as from renewable sources or storage systems.
Load management refers to the targeted reduction or increase of electrical loads. These loads can include charging infrastructure, industrial equipment, or other electrical consumers. Load management can thus be a part of a broader energy management system, aiming to optimize power distribution and reduce peak loads.
Charging management specifically controls and monitors the charging of electric vehicles, taking into account various vehicle characteristics and charging strategies. It is a specialized form of load management, with the key task of distributing available charging power across multiple charging points without exceeding power limits.
Benefits of Energy Management Systems
Reduce Costs
With dynamic load management, you can avoid costly load peaks by efficiently distributing charging power. This significantly reduces your demand charges and overall energy costs.
Charge More Efficiently
Energy controllers allow you to actively manage your power consumption and prioritize specific devices, such as individual charging stations, in the power distribution process. This enables you to charge your electric vehicles based on their specific needs, even with varying parking times.
Minimize Risk of Outages
By evenly distributing the available power at all times, you ensure a consistent load on the public power grid. This contributes to a stable grid operation and reduces the risk of power outages caused by excessive grid demand.
Static vs. Dynamic Load and Charging Management
Charging management systems distribute the available charging power across charging points without exceeding the power limit. Charging infrastructure meets various user needs using load and charging management systems: maximizing existing grid connection capacity, avoiding costly load peaks, and meeting user-specific mobility requirements.
- In static load/charging management, a specific yet contant amount of charging power is reserved for all charging stations. The other power demands at the connection point are not considered.
- In dynamic load/charging management, the charging power for the infrastructure can change and be dynamically allocated. The charging power can be adjusted based on an energy meter at the connection point or by an external control system, allowing for real-time adaptation to the overall energy consumption and grid conditions.
Energy Controllers: Full System Integration and Control
By using energy management controllers, components such as charging infrastructure, photovoltaic systems, and battery storage can be efficiently monitored, managed and integrated into an energy system. Energy management controllers ensure that available power is optimally distributed across charging points without causing costly load peaks. This enables simultaneous charging of multiple electric vehicles without requiring significant investments in grid expansion.
With the use of energy management controllers, you can:
- Ensure compliance with available power capacity and technical grid connection conditions.
- Reduce electricity costs by capping load peaks.
- Distribute available power based on demand, for example, prioritizing the charging of electric vehicles.
- Fully integrate electrical consumers, generation systems, and storage units.
- Implement dynamic power allocation for charging infrastructure, considering building loads, secondary loads, PV systems, and battery storage.
