AC batteries are frequently charged using both single-phase (1ϕ) onboard slow charging and three-phase (3ϕ) onboard fast charging. Through the use of DC charging techniques, batteries can be charged quickly. Two further subcategories of DC charging technologies are off-board fast charging and off-board rapid charging systems.
Wired and wireless charging are the two ways battery electric vehicles can be charged. In the wired charging technique, direct cable connections between the electric vehicle and the charging apparatus are provided, which may be further separated into AC and DC charging technologies.
For managing the EV charging technology, a single-objective optimization is used to determine the optimal size of the charging technology both on-board and off-board and to determine a suitable battery capacity. The proposed optimization allows to find the optimal trade-off between the onboard and off-board charger power rate.
With this charging strategy the charging current is injected into the battery in form of pulses, so that a rest period is provided for the ions to diffuse and neutralize. The charging rate, which depends on the average current, can be controlled by varying the width of the pulses.
The trade-off between high capacity and fast charging comes down to the way charged molecules called ions move around in batteries. As a battery charges, an electric current pushes lithium ions from one side of the cell to the other. The ions can then nestle into spaces in part of the battery called the anode, where they wait.
Not only the choice of the charging technology, but also the selection of the correct charging method is a feature that has to be considered during the charging procedure. The most popular charging strategies to recharge Li-ion batteries are constant-current/constant-voltage (CC/CV) and pulse current charging methods [17, 18].
