Electric vehicles and their batteries are complex systems and therefore issues with respect to range anxiety, cost, safety and reliability have to be addressed on every level of the system: the materials, the cells, the system design, the battery management system (BMS) and ultimately on the vehicle level and in the interaction with its environment.
The EVERLASTING project will develop innovative technologies to improve the reliability, lifetime and safety of Lithium-ion batteries by developing more accurate, and standardized, battery monitoring and management systems. This allows predicting the battery behavior in all circumstances and over its full lifetime and enables pro-active and effective management of the batteries, which leads to more reliability and safety which enables preventing issues rather than mitigating them. Moreover, by exploiting the interaction between the battery and the vehicle, more accurate range predictions can be made to reduce the range anxiety for the driver and allows the battery to be kept in a safe and optimal operational state to improve the lifetime of the battery (target +20%) and to use the battery to its full capacity in a safe way. This will lead to lower overall costs.
The EVERLASTING project will result in a prototype battery pack, including a model-based BMS that will be designed according to a proposed standard architecture and interfaces. This battery pack will use BMS technologies developed in the project to prove their relevance and applicability in a real vehicle. Secondly, the BMS technologies to accurately predict (irrespective of battery aging) and to extend the driving range will be demonstrated in a full electric bus.
