Embodiment 1

[0034] see figure 1 The flow chart of the first method for predicting battery life is shown, the method is executed by a server, and the server is connected in communication with the charging terminal. Specifically, the charging terminal can be a device capable of providing electric energy such as a charging pile for charging the battery, and can also detect the initial value and the end value of the remaining power of the battery during the charging process. The method is preferably used for batteries of electric vehicles, and the method comprises the following steps:

[0035] Step S102, obtain the current charging record of the battery through the charging terminal; wherein, the charging record includes: the starting and ending power of the charging terminal, the starting and ending values ​​of the remaining battery power; of course, the charging record can also be further displayed The difference between the starting power and the ending power of the charging terminal, and...

Embodiment 2

[0064] Considering that charging terminals such as charging piles may have losses in the process of charging batteries, the reason is that charging piles, charging guns and cables will have heat loss, which will affect the amount of electricity charged into the battery. Taking loss into account can further improve the accuracy of battery charging capacity, thereby making life prediction results more accurate. see image 3 The flow chart of the third method for predicting battery life is shown, the method is executed by a server, and the server communicates with the charging terminal. The method takes charging loss into consideration, and specifically includes the following steps:

[0065] Step S302, obtain the current charging record of the battery through the charging terminal; wherein, the charging record includes: the starting and ending power of the charging terminal, the starting and ending values ​​of the remaining power of the battery, and also includes the charging tim...

Embodiment 3

[0090] For the method for predicting battery life provided in the foregoing embodiments, the embodiment of the present invention provides a device for predicting battery life set on the server side, the server is connected to the charging terminal in communication, see Figure 4 A structural block diagram of a device for predicting battery life shown, the device includes the following modules:

[0091] The record obtaining module 402 is used to obtain the current charging record of the battery through the charging terminal; wherein, the charging record includes: the initial power and the end power of the charging terminal, the initial value and the end value of the remaining power of the battery;

[0092] A capacity efficiency determination module 404, configured to determine the current capacity efficiency of the battery according to the current charging record;

[0093] The charging times determination module 406 is used to determine the charging times corresponding to the c...

Abstract

The present invention provides a method and device for predicting a battery life, relating to the technical field of battery detection. The method is executed by a server which is in communication connection with a charging terminal. The method comprises a step of obtaining a current charging record of a battery through the charging terminal, wherein the charging record comprises starting power and ending power of the charging terminal and a starting value and an ending value of the remaining power of the battery, a step of determining a current capacity efficiency of the battery according to the current charging record, a step of determining a charging number of times corresponding to the current capacity efficiency through a pre-established battery capacity attenuation table, wherein the battery capacity attenuation table records a corresponding relation between capacity efficiency and a charging number of times, and a step of generating a life prediction result of the battery according to the charging number of times. The above battery life prediction mode is simple and convenient and has low cost, and a user can conveniently and clearly understand the service life of the battery after charging the battery.

Description

technical field [0001] The invention relates to the technical field of battery detection, in particular to a method and device for predicting battery life. Background technique [0002] Normally, the capacity of the battery will gradually decay as the number of charge and discharge increases, and the performance of the battery will also decrease accordingly. Therefore, the life of the battery is limited, that is, the number of times the battery can be charged and discharged is also limited. [0003] Taking electric vehicles as an example, the vast majority of car owners usually do not pay attention to the attenuation of the charging capacity of electric vehicles, and it is difficult to know how many times the battery has been charged and discharged, and how long its service life is, often when the battery is obviously not enough. Only when the driving mileage is obviously shortened will you notice that the battery is in poor condition. At this time, the opportunity to remedy...
