1. Charging speed. The common charger adopts constant current charging mode, and the charging speed is mainly related to the current provided by the charger. The greater the charging current, the faster the charging speed. The length of charging time is not only related to the charging speed, but also depends on the capacity of the battery. It should be noted that the greater the charging current, the higher the requirements for the internal system design quality of charger and battery.
2. Charging efficiency when charging, not all the energy input to the battery is converted into the energy stored by the battery, and some are used for the side reactions inside the battery and converted into heat during charging, so the charging efficiency is always less than 100%.
3. Time control mode is generally adopted for chargers that control small current at the end of charging. High current fast chargers generally adopt the combination of - △ V control and other control methods, with a higher degree of intelligence. The greater the current provided by the charger, the more complex the charging termination control mode, and the higher the cost and price. For users, they should choose according to their actual situation.
