Batteries play a crucial role in the domain of energy storage systems and electric vehicles by enabling energy resilience, promoting renewable integration, and driving the advancement of eco-friendly mobility. However,
Except for China, there is a significant imbalance between the local shares of the passenger car demand and the battery supply chain (Figure 4) [25-27]. For instance, in 2022, Europe had a 21% share of the global new sales of passenger cars, which is considerably more significant than its current share in the supply chain of EV batteries
According to the policy scenario to achieve the climate goals of the Paris Agreement, it is expected that the global electric vehicle stock will reach nearly 140 million
Lithium-ion batteries (LIBs) excel as a prominent choice among different energy storage options and are seen as a viable option due to their low self-discharge rate, high power densities and longer cycle life, which triggered the new path for the electric vehicle (EV) market and enabled the wide emergence of portable electronic devices [8, 9].
According to the policy scenario to achieve the climate goals of the Paris Agreement, it is expected that the global electric vehicle stock will reach nearly 140 million vehicles and account for 7% of the global vehicle fleet by 2030 [3].
Rallo et al. [13] have modelled the battery ageing in a 2nd life battery energy storage system in the energy arbitrage market in Spain. The modelled BESS of 200 kWh and 40 kW had one charging and discharging cycle per day for four hours each. They assumed a constant temperature of 23 °C, resulting in a lifetime of 12.5 years [13].

Battery degradation in electric vehicles, for instance, results in reduced energy capacity, which in turn diminishes the range of the vehicle. This means that over time, a fully charged battery won''t take you as far as it initially did. Similarly, in battery energy storage systems (BESS), battery degradation can limit the amount of energy that can be stored and delivered, impacting the

The lithium-ion batteries used in electric vehicles have a shorter lifespan than other vehicle components, and the degradation mechanism inside these batteries reduces their life even more. Battery degradation is considered a significant issue in battery research and can increase the vehicle’s reliability and economic concerns.
Figures 15 and 16 show the battery degradation curve form the initial capacity of the battery to reaching the EoL over distance and time respectively. It can be seen from Fig. 15 that, before optimization, the vehicle covers distances of 160,000 km, whereas, in optimized mode, the vehicle covers a distance of nearly 200,000 km.
The battery pack of a BEVs represents a significant portion of the overall vehicle cost; ranging from 25 to 30 % 3. Regrettably, the battery degrades and loses capacity with time and usage, which mitigates its overall stored capacity, available power, and energy. Therefore, the major barrier to the large-scale adoption of EVs is the battery aging.
Due to the non-linear behaviour of the health prediction of electric vehicle batteries, the assessment of SOH and RUL has therefore become a core research challenge for both business and academics.
For simplification, the braking energy is stored in the battery system with a fixed efficiency - f r b s, therefore, only a partial of the powertrain energy can be recycled back to the battery system. The simulation of the HVAC system in this model is based on Neubauer et al. and Maranville et al.‘s work .
Battery temperature is considered the most important variable affecting battery degradation. Extreme temperatures, whether high or low, accelerate degradation of the battery. Temperatures above or below 25 lead to an increase in the aging rate.
