What is a mobile battery?
A mobile battery is a portable unit for battery power storage. The system stores energy in powerful lithium-ion batteries and delivers it when you need it. Thanks to the plug-and-play design, our solutions can be deployed quickly, without complicated installation. This makes a mobile battery ideal for temporary projects or situations where you have no or insufficient grid connection. Want to know how this connects to larger systems? Find out more in our blog on energy storage systems.
Benefits of on-site battery energy storage
The benefits of a mobile battery are immediate. You operate completely emission-free, contributing to a cleaner living environment. In addition, operation is virtually silent, which means less inconvenience for employees and local residents. It also has financial benefits: you save on fuel costs, avoid fines for exceeding emission standards and manage peak power more intelligently. This fits perfectly with current challenges such as grid congestion and peak voltage.
How does battery power storage work in a mobile unit?
A mobile battery flexibly captures the demand for power and can be combined with different energy sources. Thus, you always work efficiently and reliably, regardless of the situation:
- Electrical equipment: easily charge cranes, excavators and other electric construction equipment.
- Solar panels or wind: store renewable energy directly in the battery and use it later.
- Hybrid deployment: combine the battery with a generator for backup or longer autonomy.
- EMS (energy management system): prevent overloading and optimally coordinate supply and demand. Want to know more? Check out our article on energy management system.
Thanks to these smart technologies, you are assured of reliable energy storage that is easily scalable, from small projects to large-scale applications.
When do you choose a mobile battery?
A mobile battery is ideal in situations where flexibility and sustainability come together. Think of construction sites without a fixed connection, events that require a lot of power temporarily, or emergency situations where a reliable backup is essential. A mobile battery also offers immediate relief for businesses experiencing grid congestion or peak loads. Also discover how a mobile battery is used in a variety of industries.
