Wallboxes and charging columns with load management
Control charging currents professionally
The construction and operation of a networked charging infrastructure for properties such as apartment buildings, businesses and fleet operators should be well planned. In addition to the installation of the right hardware, professional control and the possibility of connection and integration into a suitable energy management concept are also crucial.
The solution is an intelligent, automated load management. This means that all the electric vehicles to be charged can be supplied with the necessary power. Homeowners with a solar power system also benefit from a wallbox with intelligent load management.
How does intelligent load management work?
When the electric vehicle is charging, it is not the only consumer in the company or property. At certain times of the day, many electric vehicles may need to charge at the same time - or charge when other electricity consumers are at their maximum demand (hotel kitchens, production halls, air conditioning systems, residential units after work, etc.). This is where load management, also known as "smart charging" or charge management, comes into play.
Intelligent load and charge management means not exceeding the building's grid connection capacity while distributing the available power to all consumers as optimally as possible. This means that all vehicles to be charged can be supplied with the necessary power. Therefore, during phases when many vehicles are charging at the same time, your operational reliability and cost security are guaranteed at all times. The load management system regulates the charging power, thus avoiding expensive load peaks.
MENNEKES offers this important component as an essential element of networked charging solutions for controlling the operation of multiple charging points intelligently and economically. Charging solutions by MENNEKES stand for safe charging, optimum power distribution and cost-optimization at all times.

Static load management
The maximum available current of a property or the supply network connection is known (dark gray line). Based on empirical values, the maximum available current of the entire charging infrastructure at the connection point is also known or can be determined (light gray line). Static load management means that, in the charging infrastructure, this upper limit of the available charging current can be set by a specialist technician. The load management system distributes the power to all charging points in operation and thus avoids exceeding the specification.
Dynamic load management
For dynamic load management, the electricity consumption of the property or supply network connection is measured at regular intervals. The maximum available current for the charging infrastructure can be derived from the identified values (light gray line). The load management system intelligently distributes the charging current to all connected vehicles. This dynamic upper limit of the available electricity is not exceeded.
Load management for small properties
Single family homes and apartment buildings
In small properties, such as single family homes and apartment buildings, personal consumption of solar power can be maximized by networking with one of our AMTRON® wallboxes and a home energy management system. In the future it will also be possible to connect to a smart meter gateway via an intelligent interface.
Load management for large properties
Companies
The Professional charging systems are integrated into companies' existing networks via point-to-point Ethernet. A Professional+ charging system, the AMTRON® Professional wallbox or the AMEDIO® Professional charging column serves as the master for all other charging systems. In the case of multiple charging points, due to limited grid capacity the total power required by the vehicles may exceed that which can be provided by the electricity supplier or power distributor. This is where the load management system intervenes as a higher-level controller and coordinates the charging currents of the individual charging points.
Effective blackout protection
The MENNEKES charging stations of the AMTRON® Professional and AMEDIO® Professional product ranges offer the integrated function "local blackout protection" in the form of dynamic load management. This means that operational reliability is always guaranteed, as the existing power supply is not overloaded. Fluctuations in consumption in the property are taken into account in a flexible manner. The prerequisite is to determine the current value specification using an additional external measuring device. Networking between the energy meter and the charging station can take place via a direct connection or an Ethernet network connection.
Connection to an energy management system
The charging infrastructure is integrated into the property's energy management system (EMS) using established interfaces and protocols. Compatibility and interoperability is provided with many EMS manufacturers. Phase-accurate load management includes configurable unbalanced load avoidance.
