The battery system is the key component in a full electric or a plug-in electric vehicle. Important aspects are cost, package, safety, performance and durability. With a modular design the fundamental requirements can be fulfilled at a sublevel. Providing easy and appropriate interfaces all special issues can be solved efficiently on system level. Such a module can be mass produced even in a time where a high diversification in systems can be seen in the test fleets and prototypes. The selected cell is a basis on which a battery system is built. In the case of electric vehicles specific energy is still a very important issue. So is the thermal management as temperature influences performance and life time. In the design process of Akasol an effective thermal management with a temperature imbalance of less than 1°C within a module in a standard cycle was achieved. The actual modules have an energy density of 130 Wh/kg and can be easily configured to full EV systems.
A highly integrated, mass produced battery module as basis for various EV and HEV systems.
