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%.
The present study, that was experimentally conducted under real-world driving conditions, quantitatively analyzes the energy losses that take place during the charging of a Battery Electric Vehicle (BEV), focusing especially in the previously unexplored 80%–100% State of Charge (SoC) area.
The vehicle’s internal battery pack is charged under the control of the battery management system (BMS). The majority of EV manufacturers currently use conductive charging. Fig. 14. A schematic layout of onboard and off-board EV charging systems (Rajendran et al., 2021a). 3.2.2. Wireless charging
Furthermore, it is not for the driver’s benefit to exceed 80% of SoC during charging, considering the required charging time, the distance that each SoC area provides and the life expectancy of the battery itself.
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%.
Specifically, by integrating advanced algorithms such as adaptive control and predictive control, it is possible to accurately adjust the current changes during the charging process, ensuring that the current distribution and duration of each stage reach an optimized state, thereby improving charging efficiency and battery life.
