However, in some markets characterised by widespread availability of home charging (due to a high share of single-family homes with the opportunity to install a charger) the number of EVs per public charging point can be even higher. For example, in the United States, the ratio of EVs per charger is 24, and in Norway is more than 30.
This is not a good way to predict the life expectancy of EV batteries, especially for people who own EVs for everyday commuting, according to the study published Dec. 9 in Nature Energy. While battery prices have plummeted about 90% over the past 15 years, batteries still account for almost a third of the price of a new EV.
The coordinated planning of charging stations can be further improved considering the characteristics of large-scale distributed energy storage and flexible charging and discharging capacity of electric vehicles to achieve the goal of orderly charging and discharging, new energy consumption, and grid peak-shaving and valley-filling.
In the end, the more realistically the profiles reflected actual driving behavior, the higher EV life expectancy climbed. Several factors contribute to the unexpected longevity, the study finds. A machine learning algorithm trained on all the data the team collected helped tease out the impacts of dynamic discharge profiles on battery degradation.
Like slow chargers, public fast chargers also provide charging solutions to consumers who do not have reliable access to private charging, thereby encouraging EV adoption across wider swaths of the population. The number of fast chargers increased by 330 000 globally in 2022, though again the majority (almost 90%) of the growth came from China.
