In step S102, in the case where the battery is charged with a preset current, a present charge cutoff voltage of the battery is acquired.
In this embodiment, the charging voltage of the battery is determined by obtaining the current voltage of the battery, so as to avoid the occurrence of the situations of too slow charging or too high charging.
In step S104, in the case where the preset current and the present charge cutoff voltage satisfy the preset condition, charging is performed at the present charge voltage.
In the embodiment of the application, first, under the condition that the battery is charged by using the preset current, the current charging cut-off voltage of the battery is obtained, and then, under the condition that the preset current and the current charging cut-off voltage meet the preset condition, the battery is charged by using the current charging voltage. In the embodiment of the application, the actual charging cut-off voltage of the battery is obtained, and the appropriate charging voltage in the constant voltage stage is set, so that the condition of charging too slowly or charging falsely is avoided, the adaptability of flash charging is enhanced, and the charging is fast and safe.
In one possible embodiment of the present application, obtaining the current charge cutoff voltage of the battery includes the following steps.
Obtaining a path impedance value of the battery; and determining the current charging cut-off voltage according to the path impedance value and the preset cut-off voltage of the battery.
The cut-off voltage is related to the impedance inside the battery, but the actual path impedance value of the battery is different from the given value due to aging of the battery or the like, and in order to set an accurate charge cut-off voltage, it is necessary to reacquire the path impedance value of the battery at the time of charging to determine the current charge cut-off voltage.
Specifically, as illustrated in fig. 2, the electronic apparatus may include a battery module and a circuit board, the battery module including a battery cell, a battery protection plate, and a first battery connector; the circuit board includes a second battery connector, a charging chip module, and a processor.
The battery core is connected with the first end of the battery protection board, the second end of the battery protection board is connected with the first battery connector, the first battery connector is connected with the second battery connector, the second battery connector is connected with the charging chip module, the charging chip module is connected with the processor, and the processor is used for relevant control during charging.
Fig. 3 is a schematic diagram illustrating a structure of measuring impedance of a path between a battery connector and a battery cell. Rab is the equivalent impedance from the battery connector BAT + end to the electric core P +; rbc is equivalent impedance from the BAT + end of the battery connector to a point c VBAT pin of the charging chip; the battery voltage detection VBAT _ SENSE detects BAT + and BAT "of the battery connector, and actively detects the impedance Req, Req ═ Rab + Rde between the battery cell and the battery connector during charging.
A specific determination method of the present charge cutoff voltage is as follows.
First, the voltage U0 of the battery connector when not charged is detected.
Then, a charging pulse with a current It is sent through the cell, and the voltage U1 of the battery connector at the time of the charging pulse is detected.
The path resistance value R of the battery is calculated by:
R=(U1-U0)/It
and then calculating the change value delta V of the battery according to the path impedance value R:
ΔV=RIt
and finally, determining the current charging cut-off voltage according to the change value and the preset cut-off voltage of the battery, wherein the current charging cut-off voltage is as follows:
vnor + Δ V
Where Vstop is the current charge cutoff voltage of the battery and Vnor is the preset cutoff voltage of the battery.
In order to make the measurement more accurate, multiple measurements may be performed, and then filtered and averaged to obtain the final R, i.e., the above Req.
In one possible embodiment of the present application, in the case where the preset current and the present charge cutoff voltage satisfy the preset condition, the charging at the present charge voltage includes the following steps.
Determining the current charging voltage of the battery according to the preset current, the path impedance value and the preset cut-off voltage; and if the current charging voltage is greater than or equal to the current charging cut-off voltage, charging by using the current charging voltage.
That is, based on the determined path resistance value and the preset current and the preset cutoff voltage, the present charging voltage V of the battery, V ═ Vnor + Ichg × R can be determined, where Ichg is the preset current. And then judging whether the current charging voltage is used for charging the battery or not according to the judged current charging voltage and the current charging cut-off voltage.
That is, in the case where the charging voltage reaches the charge cutoff voltage, a constant voltage phase is entered, the voltage is constant, and the charging current is gradually decreased. At this time, the voltage does not need to be increased continuously so as to avoid damaging the battery.
In one possible embodiment of the present application, the charging method may further include the following steps.
Determining the current charging cut-off current of the battery according to the temperature of the battery; in the case where the charging current of the battery is smaller than the present charging cutoff current, the charging is ended.
In this embodiment, the temperature of the battery is different, the charging cutoff current of the battery is different, the electric core and the temperature characteristic of the battery can determine the corresponding charging cutoff current at different temperatures, and after the constant voltage charging is performed, the charging current is gradually reduced, so that when the charging current is smaller than the charging cutoff current, the charging is not performed, and the charging is finished.
Further, determining the present charge cutoff current of the battery according to the temperature of the battery may include the following steps.
And determining the current charging cut-off current of the battery according to the temperature of the battery and the corresponding relation of the pre-established temperature and the charging cut-off current, wherein the corresponding relation of the pre-established temperature and the charging cut-off current is related to the type of the battery.
That is, a test may be performed according to the type of the battery, and a correspondence relationship between the temperature and the charge cut-off current, as shown below, is established in advance as a correspondence relationship between the temperature and the charge cut-off current of a certain battery.
