About us

Since we founded our company in 2012, our goal has been to make a valuable contribution in the development and production of mobile energy storage systems. From our point of view, the state of the art offers a variety of possibilities. 

The existing variants of the classic lithium-ion batteries have their qualities and have their firm place in various fields of application. From the very beginning, we have been particularly impressed by the lithium iron phosphate technology in terms of longevity and robustness, which represents a profitable and safe alternative, especially in the logistics sector. 

For this reason, Deutsche Post has been equipping its e-bike fleet with our self-developed LiFePO4 batteries for more than 8 years, which are in continuous use over 40,000 times.

Every success is an incentive for us to approach the next project with new energy and to think one step further. We act flexibly and always solution-oriented in order to fulfill the wishes of our national and international customers quickly and professionally. 

The familial and efficient teamwork within our company creates a working atmosphere from which everyone involved benefits enormously. The expertise and resourcefulness of our highly qualified employees form the solid foundation of AES Akku Energie Systeme GmbH and noticeably increase the added value of our products and services.
