The present invention is described in further detail below with reference to figures 1-8.
Referring to fig. 1, in the method for supplying power to a lithium battery disclosed by the present invention, the current use state information is the power consumption state of the device to be charged, and the current use state information can be divided into three states, namely, a shutdown state, a standby state and a use state, and two modes, namely, a fast charge mode and a normal charge mode, are selected according to the states of different devices.
Since the electronic products to be charged are different, the use state reference information is also different, and therefore, the use state reference information of the corresponding electronic product needs to be selected and compared to determine whether the electronic product is in a use state, and the determination method is as follows:
acquiring current use state information of current equipment to be charged;
switching the output current of the lithium battery according to the comparison condition between the current use state information and the preset use state reference information;
if the current use state information is larger than the use state reference information, switching the output current to be a first-gear current;
if the current using state information is less than or equal to the using state reference information, switching the output current to be a second-class current;
and the first stage current is less than the second stage current.
The first gear current is the current of normal charging, the second gear current is the current of quick charging, the current of normal charging is about 1A, and the current of quick charging is about 2A.
In the shutdown and standby states, the fast-charging current is used, and in the use state, the normal-charging current is used.
Referring to fig. 2, during charging, a wireless charging mode is adopted, and the configuration mode is as follows:
the lithium battery is provided with a transmission end, and the equipment to be charged is provided with a receiving end which mutually induces with the transmission end to realize charging;
the device to be charged is also provided with an electronic tag corresponding to the use state reference information, and the lithium battery is provided with an inductor for inducing the electronic note;

The electronic tag and the receiving end are arranged at the same position on the equipment to be charged, so that one-to-one correspondence is carried out, and an inductor used for inducing the electronic tag is also arranged at the position, close to the transmission end, on the lithium battery.
The use state reference information on the electronic tag is sensed through the sensor, so that the use state reference information is identified and used as a reference. The use state reference information of different types of electronic products is different.
Referring to fig. 3, the usage state information is acquired as follows:

When the electric quantity is smaller than the circuit reference information, the wireless transmitting module can send a transmitting signal to the martial art ann receiving module, the wireless transmitting module is arranged at the receiving end, and the wireless receiving module can be arranged at the transmitting end.
And once the transmitting signal is received, the feedback signal is fed back, so that the transmission is stopped, the information is transmitted for a long time continuously in one time, meanwhile, the transmitting signal is stopped from being transmitted when the feedback signal is received in the first time information, and meanwhile, the prompting is carried out through a prompting device in the second time information.
After receiving the transmitting signal, the positioning chip sends a positioning signal, and the positioning chip is installed on the receiving end. The transmitted signals pass through different frequencies, thereby distinguishing different devices. And after receiving the positioning signal, the client displays the positioning place.

In this embodiment, it is preferably 2 min.
By acquiring the charging amount and comparing the charging amount reference information, once the charging amount is detected to be small, the output voltage is increased, the voltage level is changed from a low level to a high level, and the lowest voltage level is recovered after the charging is finished.
