Embodiment 1
[0054] see figure 1 , a kind of prediction method of lithium-ion battery life, comprises the steps:
[0055] S110. Record the time Tm for each battery full charge.
[0056] It should be noted that each time the battery is charged, there is a full time, and each time it is fully charged, this time is recorded, and then the remaining service life of the battery is calculated based on this time.
[0057] It can be understood that in order to record the charging time of the lithium-ion battery more conveniently, in this embodiment, please refer to figure 2 , the steps record the time Tm of each time the battery is fully charged, specifically including:
[0058] S111. Record the charging time t of each battery.
[0059] Generally speaking, for an electronic device or electronic equipment, it will take a certain amount of time to charge the lithium-ion battery when the battery is low to when the lithium-ion battery is high, and in the prediction method of the present invention, it...
Embodiment 2
[0084] Figure 4 It is a schematic flow chart of the fourth embodiment of the method for predicting the life of a lithium-ion battery according to the embodiment of the present invention. On the basis of the first embodiment, this embodiment adds the record of the battery charging time t each time, so as to realize the calculation of the battery charging time more accurately.
[0085] In this embodiment, the step of recording the charging time t of each battery specifically includes: recording N times of charging time t1, t2, t3, . . . tn of each battery. In this way, by recording the charging time of each battery, the remaining service life of the battery can be calculated after each charging, so that the calculation of the charging time of the battery can be realized more accurately, and then the remaining life of the battery can be calculated according to the actual charging time. It also makes the prediction results more reliable.
[0086] In an implementation example of...
Embodiment 3
[0094] Figure 5 It is a schematic flowchart of the fifth embodiment of the method for predicting the life of a lithium-ion battery according to the embodiment of the present invention. On the basis of Embodiment 1 and Embodiment 2, this embodiment increases the record of the charging state S of the battery each time, so as to predict the remaining service life of the battery according to the charging state of the actual battery, which can make Prediction results are more accurate and reliable.
[0095] In this embodiment, the step of recording the state of charge S of the battery each time specifically includes: recording the state of charge S1, S2, S3, . . . Sn of each battery N times. In this way, by recording the state of charge S of the corresponding battery in each charging time, the remaining service life of the battery after this charging can be calculated in combination with the actual charging time, so that the remaining service life of the battery can be accurately p...
