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
Abbreviation: EMI, electromagnetic interference. This paper provides a comprehensive overview of wireless charging technologies suitable for electric vehicle charging. Among these technologies, namely IPT, CPT, MWPT, and MGWPT, are identified as the most suitable for charging electric vehicle batteries.
The three wireless charging technologies for EV charging (IPT, CPT, MGWPT) are compared in Table 9 in terms of performance, complexity, misalignment, compatibility with EVs charging, cost, power losses, etc. TABLE 9. Comparison of various wireless power transfer technology for electric vehicles charging applications [23, 197, 198].
Even if there are no restrictions imposed by law, charging points functioning in mode 3 typically permit charging up to 32 A and 250 V in single-phase AC and up to 32 A and 480 V in three-phase AC. Mode 4 (Ultra-fast Charging): The DC charging feature is only available in this charging mode.
The devices charge all batteries in line with a fixed one- or two-stage characteristic. With the single-stage characteristic, the charging current responds in the opposite manner to the voltage, i.e. when the voltage increases the charging current drops.
With inverter technology, the battery charging process is fully monitored throughout. The battery is charged with a constant current until a specific voltage is reached. The charger then switches to constant-voltage charging.
