The reev Energy Management System: the key to an efficient charging infrastructure

What is an energy management system?

An energy management system (EMS) monitors and controls the available energy at a location and distributes it to all active charging points as required. It ensures that the grid connection is not overloaded and that all vehicles can still be charged reliably – even if only limited connected load is available. Instead of static power allocations, a modern EMS works dynamically: it measures current consumption in real time, recognizes free capacity and uses it intelligently. This makes charging infrastructure not only technically possible, but also scalable and economically plannable in the long term.

What is dynamic load management?

With dynamic load management, the system continuously adjusts the charging power to the actual energy consumption of the location. If, for example, heat pumps, machines or office spaces in the building require electricity at the same time, the charging power is automatically reduced – without manual intervention and without any risk to grid stability.

In contrast, static load management works with fixed power limits. This is only practical for very small charging setups and quickly reaches its limits as soon as several vehicles are charging at the same time or the location grows. Dynamic load management is now the standard for professional charging infrastructure.

The reev Energy Management System in practice

The reev Energy Management System was developed to operate charging infrastructure safely, cost-effectively and with minimal hardware requirements. It is cloud-based, flexibly expandable and fully integrated into the reev Platform the software that operators use to control, bill, monitor and share charging points with user groups.

The system ensures that energy flows are automatically optimized, load peaks are avoided and new charging points can be added at any time without having to reinforce the grid connection. This means that the infrastructure not only remains stable, but is also economically scalable.

Does an energy management system reduce operating costs?

Yes. An EMS reduces energy costs by avoiding peak loads, relieving the load on the grid connection and optimizing the use of existing power. Expensive expansion costs can thus be avoided. At the same time, ongoing operating costs are reduced because energy consumption is controlled and distributed more intelligently. For operators, this means predictable costs, reliable processes and higher utilization of the existing infrastructure.

EMS + solar energy: efficient charging with your own electricity

Energy management is particularly effective when combined with photovoltaics. Surplus solar power can be used directly for charging without being fed into the grid. This reduces electricity consumption, lowers energy costs and enables climate-friendly operation. In addition, the reev Electricity Tariff can enable further optimization – e.g. through suitable tariffs for charging infrastructure.

For whom is an EMS worthwhile?

An energy management system is always indispensable when several charging points are operated, the grid connection is limited or charging infrastructure is to grow – for example in commercial properties, company fleets, residential and mixed properties or for publicly accessible charging points. In short: anyone who plans professionally needs energy management.

Why intelligent energy management is becoming a success factor

Electromobility is not a question of installed charging points, but of the intelligent control system behind them. A modern energy management system makes charging infrastructure safe, scalable and economical – and ensures that the power grid, vehicle fleet and cost structure remain in balance. With the reev energy management system, charging infrastructure becomes a controllable, future-proof energy system.
