[0002] Lithium-ion batteries have the advantages of light weight, large capacity, and no memory effect, so they have been widely used. Many digital devices use lithium-ion batteries as power sources. Although they are relatively expensive, lithium-ion batteries have a high energy density. Their capacity is 1.5 to 2 times that of nickel-hydrogen batteries of the same weight, and they have a very low self-discharge rate. In addition, lithium-ion batteries have almost no "memory effect" and do not contain toxic substances, which are also important reasons for their widespread use.

[0003] A lithium battery charger is a lithium battery charger specifically used to charge lithium-ion batteries. Lithium-ion batteries have high requirements for lithium battery chargers and require protection circuits, so lithium battery chargers usually have high control precision and can charge lithium batteries with constant current and constant voltage. However, existing lithium battery chargers usually only have one charging compartment, which means that they can only charge one lithium battery at a time and cannot charge two lithium batteries at the same time, affecting the charging efficiency and user experience. In addition, they only have the function of charging, which is relatively simple.
