Problems solved by technology
In order to complete the charging, a charging circuit is usually provided in the charger, through which the charging of different stages of the battery is completed. This way of repeatedly completing the charging of different stages through a charging circuit, because the entire charging process of the rechargeable battery Among them, the charging circuit is always in the working state when charging. On the one hand, it affects the service life of the charger. On the other hand, the continuous heating of the charging circuit will also cause charging safety risks. In addition, when charging multiple batteries at the same time, the charging efficiency is low. , the manufacturing cost of the charger is also high; in addition, the charger usually can only charge a certain type of rechargeable battery suitable for the same charging program, and cannot charge rechargeable batteries compatible with different charging programs at the same time

The invention relates to a charger, which comprises a plurality of charging circuits and is characterized in that the charger acquires information of a rechargeable battery and selects the corresponding charging circuit to charge the rechargeable battery in a time-sharing manner according to the acquired information of the rechargeable battery. The invention also protects a charging method. The charger and the charging method can be compatible to effectively charge batteries suitable for different charging program stages.
Description
technical field [0001] The invention relates to the field of charging. Background technique [0002] At present, during the charging process of the rechargeable battery, it usually needs to go through several different charging stages to complete the charging of the rechargeable battery, such as the two-stage charging mode or the three-stage charging mode of the lead-acid battery. In order to complete the charging, a charging circuit is usually provided in the charger, through which the charging of different stages of the battery is completed. This way of repeatedly completing the charging of different stages through a charging circuit, because the entire charging process of the rechargeable battery Among them, the charging circuit is always in the working state when charging. On the one hand, it affects the service life of the charger. On the other hand, the continuous heating of the charging circuit will also cause charging safety risks. In addition, when charging multiple...
