E-Mobility – Solutions for Load Management

Electric vehicle (EV) charging is growing in importance as part of the energy and mobility transition. Intelligent charging point distribution and load management is the key challenge in expanding e-mobility for grid operators, facility managers and industrial companies.
For the e-mobility charging infrastructure, WAGO offers customized solutions for connection and energy flow control.

WAGO Application Load Management

Dynamic and Static Load Management: Optimal Utilization of Charging Infrastructure

Tailored but cost-effective – these are the core attributes of the WAGO Application Load Management software solution. It allows intelligent, sustainable electrical vehicle charging with continuous power adjustment and utilization of all available capacity. It also boasts maximum scalability and compatibility with standard wall boxes and charging stations from many manufacturers.

One compelling feature is that a cloud connection, though possible, is not essential. Licensing is a one-time cost, and the application’s technical flexibility and technological interoperability support easy, cost-effective, sustainable integration into existing charging infrastructure. Thus WAGO Application Load Management allows renewable energy systems to incorporate additional loads and storage systems and to use existing grid connections optimally.

Your Benefits:

  • Maximum compatibility and scalability 

  • Optional offline operation (if needed) 

  • Complete control over costs  

  • Avoid load peaks

E-Mobility – Solutions for Load Management

The solution can run on the following Docker®-capable WAGO controllers: the WAGO Compact Controller 100, WAGO Edge Controller, second-generation WAGO PFC200 and WAGO Touch Panel 600. The Compact Controller 100’s design makes it especially suitable for integration into existing control cabinets. WAGO’s Load Management application is compatible with standard Modbus®-capable power measurement modules and smart meter gateways. Data can be exchanged via a wide range of communication protocols, including OCPP 1.5 or 1.6, Modbus® and others. Since application configuration and management are performed via a Web interface, these processes are location- and software-independent.

Load Management Solution Is More Than Charging Station Management

The tremendous growth of electromobility is a catalyst for the energy transition for cross-asset load management solutions. With WAGO technology, the integration of e-mobility and load management can be implemented as a holistic, future-ready energy management system. This flexibly balances the generation, storage and consumption of renewable energy with supply security.


Grid Connection Point

The grid connection point – GCP for short – is the hard part. It requires a grid-compliant connection. Load management ensures that the fuse is not overloaded.


Renewable Energy Generation

Renewable energy generation is decentralized and fluctuates, for example in wind farms, photovoltaic and biogas plants or CHP plants. Load management ensures that the energy generated can be used efficiently and fed into the grid in a way that is appropriate for and compliant with it.


Charging Infrastructure

In order to make e-mobility possible, charging infrastructure is needed over a wide area. For this purpose, WAGO offers both static and dynamic load management that is appropriate for the grid.


Energy Storage Systems

From small home storage systems, to large battery storage systems, to industrial hydrogen storage systems – connected storage solutions make green electricity usable even when there’s no wind or sunshine.


Energy Consumers

Buildings of all kinds and production facilities require energy – with electricity-based loads such as heat pumps, their power requirements increase. Therefore, load and energy management also include energy-efficient building management and peak load capping in industry.

Building Technology

More and more, the trend towards building self-sufficiency requires control of numerous energy flows. In the future, a management system for load control of cooling technology, charging stations or heat pumps will be indispensable.


Digital Plant

A large number of dynamic loads in the industrial sector can cause significant load peak fluctuations. The result is load peaks, which drive the demand charge way up. An energy management system from WAGO can prevent this.


FAQ – Questions and Answers about E-Mobility
and Load Management for Charging Infrastructure

A load management system for charging infrastructure allows the expansion and integration of e-mobility into power grids. Load management for electric vehicle charging controls the power of multiple charging points in order to optimize utilization of the existing existing grid connection – without the need for a power rating increase or even a new transformer at the grid connection point. Therefore, where there are multiple charging points, a load management system is usually necessary for integration of the charging infrastructure, because buildings, parking lots and underground garages are generally not designed with large power reserves.

Static load management is the simplest kind of load management system, where a preset static energy value is available to all loads. Static load management does not take any other consumers or generators into account.

An example of static load management for charging infrastructure:

Three charging stations are available with a total capacity of 22 kilowatt hours. If only one electric vehicle is charging at the three charging stations, it can be charged at the full 22 kilowatt hours. If two vehicles are connected, these 22 kilowatt hours are distributed equally among the two charging points.

Dynamic load management differs from static load management in one fundamental respect: The available energy is no longer static, but variable. In dynamic load management for charging infrastructure, the capacity is measured and dynamically distributed among the charging stations. For example, if the sun shining on solar power installations that feed into the grid, the total available charging power at the charging stations is increased to optimize utilization of the available electricity.

From the energy industry’s point of view, load management is necessary in order to keep grids stable and ensure security of supply. In the area of e-mobility, this means supplying the growing charging infrastructure with the additional electricity it needs without overloading the grid interconnection points. This requires generation and consumption – as well as storage, if applicable – to be harmonized. But renewable energy from decentralized generators fluctuates. Therefore, it is important to use surplus energy in the grid through flexible loads. This is exactly where WAGO comes in. Load management regulates the flow of energy and controls all loads, energy storage systems and generators in the energy network.

In addition to the cost of energy consumed, industrial and commercial companies and large properties whose consumption exceeds 100 megawatt hours (MWh) must pay a so-called demand charge: the price that has to be paid if the set power limit is exceeded. For the demand charge, the maximum average power consumption is calculated at a quarter-hour intervals. Normally, the quarter hour with the highest mean value is applied to the whole year. For example, with a demand charge of 110 euros per kilowatt (kW), a load peak of 1,000 kW can lead to additional annual costs of 110,000 euros. With the integration of a charging infrastructure for e-mobility, an additional consumption factor is added. Therefore, intelligent load management for energy flows is extremely important, especially for preventing peak loads (so-called “peak shaving”) in order to avoid additional costs.

Energy management is a higher-level system in which all load currents of consumers and generators are continuously measured, monitored and optimized. Energy management systems are used in intelligent networks such as smart grids, microgrids and nanogrids to improve energy efficiency. This includes real estate, industrial companies and even utilities. A fundamental goal is to minimize the consumption of auxiliary materials, additives and raw materials. Load management for charging infrastructure ensures a sensible distribution of existing loads within the energy management. So load management is only part of an overall energy management package – albeit an important one.
