Together with our clients, we develop customised battery storage solutions for unusual applications

We collaborate closely with our customers to define battery system requirements, estimate what is technically feasible, and develop an initial concept, pushing the technical boundaries as much as possible. We endeavour to deliver the maximum for our customers, no matter how stringent or unusual their requirements: Extremely lightweight, high performance, or compact design solutions, or specific applications, such as air or maritime.

Safety concept A detailed safety concept requires intensive study of the planned deployment scenario, as well as the intended application environment for the storage system. In dialogue with our customers, we develop a suitable security concept to meet any application-specific functional requirement. This includes safety and transportation certificates (UN 38.3).

Electronics development

At Air Energy, electronics development is inextricably linked to system development. Air Energy's battery management system for Li-Ion batteries has been in constant development since 2003, and is immediately available in several variants for new projects. Battery management systems, chargers and dischargers are developed by a single provider and, therefore, work flawlessly together. Safety-related functions (e.g., gauges, stop-charge, stop-discharge, etc.) provide built-in redundancy.


Thermal management

We design thermal solutions without active cooling to ensure our battery systems are space and weight-optimised. On the other hand, we develop active air or liquid cooling for high-performance applications.



Our highly experienced team develops creative solutions to overcome any space-related constraints for our battery systems. Not surprisingly, delivering lightweight and structurally demanding housing is one of our core competencies. This tall order is met by constantly introducing new materials and manufacturing processes.


Charging concept 

Our battery is supplied with a charger specially designed for it. The interaction of our battery with the charger electronics ensures maximum service life and optimum protection against overcharging.


Discharging concept

Upon request, we supply batteries with a discharger. Dischargers are designed to lower battery state of charge as to increase transport safety and minimise battery aging upon prolonged storage.
