Load management and charging logic
ChargePilot® offers load management that optimally distributes charging power across the connected vehicles and meets custom requirements.
The local power grid often cannot provide sufficient charging capacity for multiple vehicles. This is where intelligent load management comes into play: It not only saves you from the high investment costs of grid expansion but also prevents costly peak loads and high ongoing energy expenses. This is achieved by strategically allocating the charging power to multiple charging points while staying below a set power limit. Depending on your needs, various types of load management can be applied to maximize the advantages at the charging site.
The basic question: static or dynamic?
Electric vehicles can be charged with a set maximum charging load limit (static) or a flexible limit that takes other consumers into account in real-time (dynamic).
Static Load Management
When integrating charging stations into a new grid connection or an existing distribution without additional consumers, it is sufficient to use ChargePilot® Static Load Management with a defined maximum power limit. In this setup, ChargePilot® allocates the available power to the connected electric vehicles while considering phase load. The power distribution is continuously optimized: For instance, if a vehicle is fully charged and no longer requires power, the excess energy is redirected to other charging points. However, the overall charging power availability remains constant and does not adapt to external factors such as building load. This solution is therefore suitable for sites with minor consumption fluctuations.
Dynamic Load Management
When integrating charging stations into an existing distribution with other consumers (e.g., lighting, heating and elevators), ChargePilot® Dynamic Load Management is typically the most beneficial choice. A locally installed meter provides real-time measurements of the energy consumption. ChargePilot® continuously considers the meter values, adjusting the available charging power accordingly and thereby ensuring the efficient utilization of the available power. For instance, if consumption decreases in the building, more electricity becomes available for the vehicles to charge. With real-time metering and continuous power adjustment, taking phase load into account, ChargePilot® is the most efficient system on the market.
Additional load management variants
Schedule-based Load Management
Our Schedule-based Load Management allows charging the electric fleet according to a certain time table. ChargePilot® then takes into account the stored vehicle profiles with departure times and energy requirements of each vehicle. Consequently, vehicles that need to be ready for use earlier are charged first.
Time-based Grid Limits
If energy rates vary during specific periods, such as nighttime versus daytime, ChargePilot® Time-based Grid Limits feature is beneficial. The grid limit is automatically reduced during predefined time intervals to save costs or account for regularly occurring site loads. This setting can be easily activated or deactivated within the ChargePilot® Dashboard.
Charging sites with multiple electric vehicles and simultaneous charging sessions can strain the grid, leading grid operators to often request control over these sites. ChargePilot® Grid-friendly Charging allows precisely that: controlling the charging power in accordance with the grid operator's requirements, enabling compliance with § 14a of the German Energy Industry Act (EnWG).
If needed, ChargePilot® can also incorporate locally produced energy from such sources as a photovoltaic system into the intelligent load management for your charging infrastructure.
Optimal grid utilization. Efficient charging.
ChargePilot® controls electric vehicle charging with a logic that is subject to a number of rules. These rules ensure that electric vehicles are charged in the most reliable, easy and affordable way possible.
Charging in compliance with all limits to avoid peak loads or mains connection overload.
The power output is adjusted dynamically to suit the requirements of the electric vehicle so that power is distributed efficiently.
Where possible, all connected vehicles are charged simultaneously, with the available power distributed evenly between them.
If the power is not sufficient to charge all electric vehicles, priority is given to the vehicles that were connected first.
ChargePilot® can accommodate the minimum amperage of vehicles and charging stations.
The available power is adjusted in accordance with the charging status of the vehicles (ready for charging: yes/no).
The optimization of all phases is performed individually, as the phases of the power grid are subject to different loads.
Vehicles can be prioritized and given the maximum desired power.
