The products produced by Panasonic batteries are all standard products, so the charging methods that can be used are also to meet the requirements of national standards. The following several charging methods are all normal charging situations, and the charging time is basically around 15 hours to fully charge the battery.
First, constant current charging method
From the literal sense you can see that since it is constant current that means that the current used in the charging process of the battery is constant. If you want to save charging time, you can theoretically use a higher current, which can be seen at roadside fast-charging stations, where the current used is relatively high. However, if you charge with high current, the active material on the electrode plates will fall off abnormally, which greatly reduces the service life of the battery, as the temperature of the battery will become very high after a period of charging.
Second, constant voltage charging method
This charging method can effectively avoid overcharging of the battery. However, as the voltage and current are inversely proportional to each other, the charging current of the battery becomes smaller and smaller, so the effect of late charging is not very satisfactory.
Thirdly, the graded constant current charging method
This method is more eclectic and has basically no effect on the life of the Panasonic battery.
