The fast charging charger adopts constant current and constant voltage charging technology, and its charging current and voltage vary according to certain rules. At the beginning of charging, the charger will output a large current, and the output voltage of the charger has not yet reached the set value, so the charging speed is relatively fast at this time. As the battery voltage gradually increases, the output current of the charger will gradually decrease. When the voltage reaches the set value, the charger will enter the maintenance phase. At this time, both the charging current and voltage will decrease, and the charging speed will slow down.
The fast charging speed of a fast charging charger is based on certain prerequisites, such as fast charging wires, power supply, and mobile phones. If these prerequisites are not met, even if a fast charging charger is used, the charging speed cannot be improved. In addition, the fast charging charger has a more excellent protection function for the battery, which can effectively prevent overcharging, discharging, and other situations, making the battery life more durable. By combining constant current and voltage charging technology with battery protection function, fast charging chargers can not only achieve fast charging but also ensure battery safety.
In summary, the reason why fast charging chargers can achieve fast charging is due to the use of constant current and voltage charging technology. The charging process is fast and then slow because as the battery voltage approaches the maximum value, the charging current gradually decreases, leading to slower charging speed. At the same time, the fast charging speed of the fast charging charger also needs to be matched with other conditions to achieve.
