AKASYSTEMS count amongst the world’s most powerful battery solutions for vehicles with hybrid or electric drives. The systems are designed in a modular fashion and are freely scaleable, which means they can be adjusted optimally to the energy needs of whatever vehicle you are using. The scaleable lithium-ion AKASYSTEM battery systems are based on highly-integrated AKAMODULEs, which achieve an energy density of more than 140 Wh/kg and can cover large distances between charges.

The designs chosen for the AKASYSTEMs focus on vehicle construction and feature connections ready for serial production by automotive manufacturers. Integration in fully-electric and hybrid vehicles is simple and does not entail any major effort or expense.

Another benefit is the extremely compact design of the various AKAMODULEs which require very little space within the vehicle thanks to the innovative and effective water-glycol cooling system. The AKAMODULEs and fused together with a cooling system within a robust case to form a single, compact unit that combines minimal weight with maximum power. Furthermore, the active thermal management within AKASYSTEM has been optimised to guarantee a constant temperature – even at high workloads – and significantly increase service life.

More information about our systems


All AKASYSTEMs can be charged quickly using a high-power supply, which means short waiting times for charging and a high level of vehicle availability. AKASYSTEMs are tested and verified several times – down to the performance of the very last cell.
