NEEDS-BASED TECHNOLOGIES

Prismatic lithium-ion secondary cells

All-electric vessels for short-haul operations, such as ferries, are currently equipped with a battery storage system based on numerous NMC graphite round cells. 81% of the round cells used are carried unused as dead weight to ensure performance. This means that 81% of the system costs would be avoidable in the best case with an optimal technology. The risk of failure due to the high number of cells and the fire hazard due to inhomogeneous ageing and high power charging is also high. The service life of the round cells is very short at just a few years. All this leads to unnecessary risks and very high total operating costs.

With a technology developed by ALSE, ATLAS ELEKTRONIK, SUNLIGHT and CUSTOMCELLS® these disadvantages can be neutralized. CUSTOMCELLS® is responsible for electrode development and production in prismatic cells. Due to the large format of the prismatic cells, the number of cells is small and the failure rate of the individual cells low. The selection of the active material leads to high service life expectations and a reliable cell design. The cells are optimized for the travel profile of ships and no expensive and maintenance-intensive cooling system is required. A battery management system (BMS) can be easily integrated into the battery compartment. The BMS controls the charging and discharging of the battery and ensures high battery availability. The amount of weight carried and thus the operating costs decrease dramatically.
