Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] as attached figure 1 and attached figure 2 As shown in the figure, a method for calculating and estimating the remaining capacity of a battery based on the Internet of Things technology includes the following steps:

[0038] S1: The battery enters the cabinet to record the battery power value: the user connects the low-power battery to the charging interface in the power exchange cabinet, and the battery starts to collect information and enter the charging state;

[0039] S2: Calculate the cumulative value of the current charging power after the battery is charged: get the cumulative value of the current battery charged in the power exchange cabinet;

[0040] S3: Record the full charge value of the battery after charging is completed;

[0041] S4: Calculate the remaining power of the current battery and report it to the cloud platform;

[0042] S5: The clou...

Abstract

The invention discloses a battery residual capacity calculation and estimation method based on the Internet of Things technology, and the method comprises the steps: recording a battery electric quantity value after a battery enters a cabinet, calculating a current charging electric quantity accumulated value after the battery is charged, recording a full-charge electric quantity value of the battery after the charging is completed, calculating the current residual electric quantity of the battery, and reporting the residual electric quantity to a cloud platform; the attenuation rate of the battery is calculated, the future battery remaining capacity is estimated according to the attenuation rate, the battery remaining capacity and battery attenuation can be detected, and replacement and maintenance are facilitated in time.

Description

technical field [0001] The invention belongs to the field of battery replacement, in particular to a method for calculating and estimating the remaining capacity of a battery based on the Internet of Things technology. Background technique [0002] During the continuous use of lithium batteries, the capacity of the battery is gradually attenuated, and the charge and discharge performance is gradually reduced. At present, the shared battery swap industry is emerging in China, and users lease batteries. Enterprises need to monitor the use of batteries when they put batteries on the market. Among them, the remaining capacity of the battery is an important parameter to be detected, which involves the operating cost of the enterprise and the quality of the enterprise service. SUMMARY OF THE INVENTION [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a method for calculating and estimating the remaining batt...
