“…While providing the mentioned benefits, battery performance is impaired by battery degradation through chronological and utilisation causes. For example, Bouchhima et al [2] explain that the battery health state describe the current EV performance [2]. This health state is influenced by permanent and inevitable degradation [4,16].…”

“…This is because after the battery health drops below 80% SoH, the capacity fades rapidly [29]. Thus, the End-of-Life (EOL) of EV batteries is estimated to be 80% SoH [2] i.a. The small lifetime range with regards to the SoH classification therefore needs to be preserved.…”

“…Besides the general context of battery degradation, there exist static recommendations with give advice in order to reduce the effects of cyclic and calendaric ageing of Li-ion batteries. On one hand cyclic ageing takes place because charge throughput into and out of the battery during cycles of driving and charging [2,22,26] at typical EV use. On the other, calendaric ageing is observed over the course of time and the powered off state of the EV.…”

“…Also, the DoD (Depth of Discharge) is often used as measure, which is the difference between 100% and SoC at a certain point in time [20]. In general, it should be avoided to frequently discharge the battery to a high DoD ( [2] i.a.) in order to prolong battery lifetime.…”

Prolonging the lifetime of batteries in Electric Vehicles (EVs) becomes a more and more important issue for private users and fleet operators. In addition to the environmental point of view, a better battery health results in less cost, higher battery capacities and higher performance. To achieve this, the EV drivers or the fleet operators need to get proper information, which kind of actions will increase or decrease the batteries health. To this point, various tips and recommendations exist distributed over literature. Unfortunately, those kind of recommendations are hard to follow in the day-today routine. This paper suggests so called dynamic recommendations for battery health that are able to advise the user in specific situations with respect to battery use. Recommendations from literature are broken down into a list, which can be automatically computed. Recommendations will then be dynamically created in the current context of the EV and displayed to the user just in time.
