The working principle of the charging device of the present invention is specifically described below by taking 3 lithium ion batteries with the same preset charging current as an example, and assuming that the preset charging currents of the 3 batteries to be charged are all I0:
1. by monitoring the charging current of the battery to be charged while charging 3 lithium ion batteries having the same preset charging current
When the sun illumination reaches a certain intensity, the solar energy component 2 converts solar energy into electric energy and transmits the electric energy to the power management module 3.
The electric quantity obtaining unit 11 of the charging module 1 obtains the remaining electric quantities of the 3 lithium ion batteries to be charged.
The charge sequencing unit 12 of the charging module 1 determines the 3 lithium ion batteries as the 1 st to-be-charged battery, the 2 nd to-be-charged battery and the 3 rd to-be-charged battery according to the sequencing of at least more remaining charge.
The control signal generation unit 15 of the charging module 1 generates a control signal for charging the 1 st battery to be charged, which has the largest remaining capacity (capacity is less than full).
The power management module 3 receives the control signal and controls the opening of the charging channel between the 1 st battery to be charged and the solar module 2 according to the control signal.

The current comparing unit 14 of the charging module 1 compares the charging current I1 of the 1 st battery to be charged with a preset charging current I0, wherein the preset charging current I0 refers to the maximum charging current of the battery to be charged.
If the charging current I1 of the 1 st battery to be charged is equal to the preset charging current I0, i.e. i1=i0, it indicates that the current power output by the solar module 2 is sufficiently large, and at this time, the control signal generating unit 15 of the charging module 1 generates a control signal for charging the 2 nd battery to be charged.
The power management module 3 receives the control signal and controls the charging channel between the 2 nd battery to be charged and the solar module 2 to be opened according to the control signal, so that the electric energy output by the solar module 2 charges the 1 st battery to be charged and the 2 nd battery to be charged simultaneously.

If the charging current I1 of the 1 st to-be-charged battery and the charging current I2 of the 2 nd to-be-charged battery are equal to the preset charging current I0, i.e. i1=i2=i0, respectively, which indicates that the current solar module 2 outputs electric energy with a margin, the control signal generating unit 15 of the charging module 1 generates a control signal for charging the 3 rd to-be-charged battery.

2. In the charging process, the charging is stopped in time along with the weakening of the output electric energy of the solar module 2
(1) In the process of simultaneously charging the 1 st to-be-charged battery, the 2 nd to-be-charged battery and the 3 rd to-be-charged battery, the current obtaining unit 13 of the charging module 1 obtains the charging current I1 of the 1 st to-be-charged battery, the charging current I2 of the 2 nd to-be-charged battery and the charging current I3 of the 3 rd to-be-charged battery in real time.
The current comparing unit 14 of the charging module 1 compares the sum of the charging currents I1 to I3 of the 1 st to 3 rd to-be-charged batteries with 2 preset charging currents I0.
If the sum of the charging currents I1 to I3 of the 1 st to 3 rd to be charged batteries is smaller than the sum of the 2 preset charging currents I0, i.e. i1+i2+i3 < 2I0, it is indicated that the output power of the solar module 2 is weakened, and the 1 st to be charged battery, the 2 nd to be charged battery and the 3 rd to be charged battery cannot be charged simultaneously, at this time, the control signal generating unit 15 of the charging module 1 generates a control signal for stopping charging the 3 rd to be charged battery, so as to ensure that the 1 st to be charged battery and the 2 nd to be charged battery with more residual power are charged at the highest speed.
(2) In the process of simultaneously charging the 1 st to-be-charged battery and the 2 nd to-be-charged battery, the current obtaining unit 13 of the charging module 1 obtains the charging current I1 of the 1 st to-be-charged battery and the charging current I2 of the 2 nd to-be-charged battery in real time.
The current comparing unit 14 of the charging module 1 compares the sum of the charging current I1 of the 1 st battery to be charged and the charging current I2 of the 2 nd battery to be charged with a preset charging current I0.
