Regarding the charging methods for new energy private cars (Fig. 5.10), the fast charging duration is mainly concentrated within 2 h, with vehicles with a duration within 2 h accounting for 93.3%; the distribution of slow charging duration is relatively dispersed, with vehicles with a duration of 2–6 h accounting for 60%.
Taking the 75 kWh battery pack as an example, this capacity generally enables a driving range of about 400 km, but the charging takes at least 12 h, considering that the charging power of slow charging piles is generally 3.3 kW or 6.6 kW.
The specific indicators under analysis are as follows. The average single-time charging duration of new energy private cars concentrated at 1–4 h, and the proportion of new energy private cars with an average single-time charging duration of 1–4 h in the past two years has reached over 60%.
Considering the proportion of vehicles charged at different charging times in the past two years (Fig. 5.98), the proportion of vehicles using fast charging has increased in the two time periods of around 10:00 and 15:00–16:00 in 2021, while the proportion of vehicles using fast charging during the day has increased.
Figure 19 demonstrates that batteries can store 2 to 10 times their initial primary energy over the course of their lifetime. According to estimates, the comparable numbers for CAES and PHS are 240 and 210, respectively. These numbers are based on 25,000 cycles of conservative cycle life estimations for PHS and CAES.
Charging System maintenance of the charging system is also a critical is sue. reliability of the charging components. Another central connector. The J1772 standard (Sanguesa et al., 20 21) of the IE C-62196.

It is best to never charge your EV battery over 80 percent. Charging happens in such a way as to put stress on the battery pack the closer you are to a 100 percent charge. Adding that final 20 percent will tax the battery. New EVs allow you to set a charging maximum to help you preserve battery life. Likewise, never let your battery discharge ...
