The ability to connect local generation and storage equipment to the charging station gives the advantage of a power support whenever the network is not able to meet the needs of the system.
Due to the high energy requirements of the vehicle and the restricted availability of stops and parking, dynamic charging is the most practical method to support highway travel. Quasi-dynamic charging charges the car when it is briefly halted, as at a traffic signal or a bus stop, expanding the driving range and enabling EVs to store less energy.
Therefore, to improve charging efficiency and user experience, ensure charging safety and battery lifespan, establishing and selecting scientific charging strategies for safe, efficient, and stable charging is crucial in accident prevention. Traditional fast charging methods usually entail charging the battery with high currents.
Actually, there are two typologies of charging: Alternating Current (AC) charging and Direct Current (DC) charging: in the first case, the AC/DC converter is installed inside the electric vehicle, whereas in the second case it is installed inside the charging station.
When establishing design standards based on charging time, it is crucial to consider the safety and reliability of batteries. Insufficient charging time can result in incomplete charging or battery damage due to excessive charging current, leading to a chemical imbalance within the battery.
