DOI: 10.1016/j.apenergy.2019.113793 Corpus ID: 203133253; Impact of high-power charging on the durability and safety of lithium batteries used in long-range battery electric vehicles
The single exception was in our exploration of public DC fast charging where sensitivity to high charge rate was modified. Where batteries are highly sensitive to high charge rates, we found that ubiquitous public DC fast charging could significantly affect battery degradation. However, this had little impact on utility. 5. Conclusions
The effect of varying charger power is investigated by using ''low'' and ''high'' power scenarios. The low power scenario is based on ''slow'' home charging (single phase 16 A, 230 V) and workplace/public destination charging (three phase 16 A, 230 V); en route charging rate are based on the max DC charging ratings of the three representative …

Overall, the impact of battery degradation on optimal charging and discharging is pronounced. Considering CD-based degradation alone may result in long-lasting high resting SOC levels, as well as cycles in the higher and lower SOC spectrum, which may accelerate calendar aging. Thus it is advisable to consider multiple mechanisms.
Battery state of charge refers to the level of charge of a battery relative to its capacity and is usually expressed as a percentage. Measuring battery state of charge is not a straightforward task, and several methods are used, including voltage, current integration, impedance spectroscopy, and coulomb counting.
