Piece N is used to calculate the electricity of rechargeable battery N.
Specifically, in practical applications, voltameter chip can by detect the input or output current of rechargeable battery come
Calculate the electricity of rechargeable battery.For example, as it is known that the capacity of rechargeable battery is 2500mAh, electric quantity of rechargeable battery has been expired, voltameter core
Piece detects the rechargeable battery with the output current discharge 0.5h of 2000mA, then remaining capacity is 2500mAh-2000mA*0.5h
=1500mAh, the electricity percentage of the rechargeable battery are 1500mAh/2500mAh=60%.
The step of various methods divide above, be intended merely to describe it is clear, when realization can be merged into a step or
Certain steps are split, multiple steps are decomposed into, as long as including identical logical relation, all in the protection scope of this patent
It is interior；To adding inessential modification in algorithm or in process or introducing inessential design, but its algorithm is not changed
Core design with process is all in the protection scope of the patent.
Third embodiment of the invention is related to a kind of charging method, as shown in Figure 3, comprising:
Step 301: preset charged electric current.
Specifically, every piece of rechargeable battery due to itself material, can all have a charging current upper limit, it is preset
Charging current is necessarily less than on this and limits.
Step 302: charging chip charges to rechargeable battery according to preset charging current.
Specifically, charging chip after connecting with charging interface, just with the output of preset charging current, makes rechargeable battery
It is charged with preset charging current.
It is not difficult to find that present embodiment is embodiment of the method corresponding with first embodiment or second embodiment,
Present embodiment can work in coordination implementation with first embodiment or second embodiment.First embodiment or the second embodiment party
The relevant technical details mentioned in formula are still effective in the present embodiment, and in order to reduce repetition, which is not described herein again.Accordingly
