The primary function of the CS is to deliver a high level of power to the battery while offering a sufficient amount of charging voltage and current, which could vary widely. The batteries are charged using DC electricity, while the grid provides most AC power. The structure of the CS for EVs is shown in Fig. 38.
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.
The charging technology, as well as the charging method, must be considered during the charging procedure. Lithium-ion batteries’ three most common charging strategies are constant-current, constant-voltage, and pulse-current charging methods .
In wired charging, two main charging categories are commonly used - AC (alternating current) and DC (direct current) charging systems. The AC charging system delivers power from the grid to the EV, which is then converted to DC by using an on-board battery charger (on-BC) available in the EV.
Battery charging infrastructure standards are being developed by different organisations based on the available market. These standards have different configurations such as charging plugs, power ratings (ac and dc), communication protocol, power quality, efficiency etc.
On-Board Charger: Most hybrid and electric vehicles are equipped with an on-board charger that allows the vehicle to be connected to an external power source, such as a household outlet or a public charging station. This charger converts electricity into direct current to recharge the battery [13, 14, 15].

Additionally, the CC/CV charging mode can be realized with two different fixed frequencies. The proposed system has a simple structure and low cost and uses only primary-side electrical information to control the battery charging profile, achieving communication-less control between the primary and secondary sides.
Constant current (CC) and constant voltage (CV) charging are two charging stages for li-ion batteries in an electric vehicle wireless charging system.
Therefore, the system voltage can range from the input voltage (when present) down to the battery voltage once the input is removed. This separation of system voltage and battery voltage is called power-path manage-ment, and is a common feature among battery chargers.
