The total charging time in the CC-CV charging method varies depending on the battery capacity and the value of the charging current in the CC mode. Generally, the battery life and charging efficiency increase as the charging current decreases under the CC mode.
Moreover, charging systems can use communications via power line devices to interact with the power grid and adjust charging according to electrical grid conditions . To maximize energy usage, prolong battery life, and prevent charging and discharging, a battery management system should monitor the battery pack during operation.
To charge the traction battery, the rectifier, SRM windings, and power converter form a 3-phase interleaved boost PFC converter, reducing input current ripple and improving charging power quality.
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
Constant-current charging entails sending a constant current to the battery during the charging process. The charging rate remains constant as the battery voltage increases. When the battery voltage is low, this method is frequently utilized in the early stages of charging. ii.
