SuperLIB contributes to the expected impacts as listed in the ICT work program of the European Commission concerning Fully Electric Vehicles (FEV) by delivering the following results:
- The usable SoC range of the battery will be increased from less than 70% to more than 90%. Thus the cost, weight and size of the battery will be significantly reduced or the driving range can drastically be increased. By both measure the consumer’s confidence in the new technology will be improved.
- In parallel the life time of the battery will be increased by up to 30% since the different cells are used just at its best points. The HE cell will not be affected by high currents, the HP cell will have only small SoC swings. As a consequence the battery replace intervals become longer, warranty costs are reduced (lower cost and risk for car manufacturers) electric cars become cheaper and total-cost-of-ownership over lifetime is being reduced. Thus also the value for 2nd hand cars will be increased.
- Due to very accurate SoC and SoH calculation and the reduced number of parts the reliability of the battery systems will be significantly improved and will enable a wide use of these batteries for the mentioned applications. The cost for car manufacturers will be decreased and due to lower prices the acceptance by consumers will be increased. This will accelerate the market penetration of electric vehicles dramatically.
- Compared to conventional systems (e.g. combining a HP and HE device on pack level) the efficiency of the suggested solution is much higher since the losses are minimised by the charge equalization board. Also the overall weight is smaller. The high efficiency will also improve the environmental performance: less energy will be wasted and thus the CO2 emissions will be reduced. Even more, less raw materials will be required especially less expensive metals like Co, Cu and Ni.
- The global competitiveness is increased in all field of the value chain that is represented by the involved partners from components level to the vehicle. Particularly the involvement of European Batteries as a European cell/battery manufacturer has to be mentioned. Europe will play a significant and leading role in battery development. It will maintain its leadership position in automotive and all secondary industries that depend on automotive. With leading European industries in this field the production of parts and vehicles can be kept in Europe and the number of employees in all those industries will not only be secured but ideally increased over the next decades.
One of the key outcomes of the project is the high reliability and safety of the developed dual-cell battery. Thus the warranty and product liability risk for all manufacturers along the value chain (cell (EB) – components (Valeo EEM) – systems (Bosch) – vehicles (Fiat, Volvo)) will be drastically reduced and the developments will not only be a technical but also commercial success. In addition, the consumer will accept these new vehicles based on an advanced technology very fast since they can trust in the durability and reliability and they can experience an extended driving range due to the high overall energy efficiency.
