Load Management​

Load management can fulfill various objectives. From charging EVs simultaneously in a fast and efficient manner while preventing local grid overloads and costly grid extensions to reducing the costs and CO2 emissions of charging through photovoltaic integration, load flattening and integration of and market price-based energy tariffs.

Without FLEXeCHARGE Load Management

Brute Force

The simplest form of load management with no intelligence. The static supply current for the EV infrastructure is simply divided by the number of charging stations. The resulting maximum supply current is then hardcoded for each charging station.

Disadvantages

Take EV Charging to the next level

FLEXeCHARGE offers the whole spectrum of possible load management solutions tailored to the needs of you customer segments.​

Application Areas

FLEXeCHARGE

Static Load Management

Static Load Management (SLM) refers to a set maximum supply current that is dynamically distributed between the charging stations depending on the connected EVs.
Our Static Load Management solution not only detects when an EV is connected, but also when the EV is done with charging to allocate the current to other vehicles.
In connection with an integrated power meter inside the charging station, the solution constantly adapts the allocated currents based on the charging behavior of the EV.

Dynamic Load Management Building integration

Connecting the charging infrastructure electrical cabinet of the building results in extremely low charging currents when managed statically. Dynamic load management considers the grid current (GC) supply and the real-time building consumption (BC) of the house to offer the remaining current to the charging infrastructure.

Dynamic Load Management PV Integration

The dynamic integration of a photovoltaic system into the charging infrastructure provides not only the possibility to increase the charging currents but also reduce energy costs an CO2 emission. By measuring the real-time production of the solar panels, the energy can be directly utilized to charge the eclectic vehicles. It is also possible to combine the photovoltaic and building integration to one load management system.

Load Scheduling

Not all charging application require to charge the electric vehicles as fast as possible. Often the EV’s are longer connected to the charging station than needed to fully charge. With charge scheduling the charge point operator is able to optimize the charging times and currents of a fleet or even a single EV based on a predefined objective.

Charging scheduling can be used to shift peak loads to times when solar power is available. By integrating solar power forecasting, energy costs and CO2 emissions can be significantly reduced, while ensuring that vehicles are fully charged when needed.

Time-of-use based energy tariffs recently gaining attention to encourage customers to use energy at off-peak times. Usually, energy prices are high in the morning and in the evening while during night and day they drop significantly. By delaying the charging process to theses times consumers can save up to 50% of their energy bill.
