Method, device, terminal and storage medium for measuring battery capacity

Abstract

The invention discloses a method for measuring battery capacity. The method includes: dividing the voltage value corresponding to the capacity of the battery to be tested into a first interval, a second interval and a third interval; The first voltage difference of the voltage and the preset first slope obtain the first battery capacity corresponding to the first interval, and obtain the first battery capacity corresponding to the first interval according to the second voltage difference of the voltage across the third interval and the preset second slope. The second battery capacity in three intervals; the battery to be tested is charged to the first boundary voltage value at the first preset rate, and discharged from the first boundary voltage value to the second boundary voltage value at the second preset rate, so as to determine the corresponding second The third battery capacity in the interval; the total battery capacity of the battery to be tested is obtained based on the first battery capacity, the second battery capacity and the third battery capacity. In addition, the invention also discloses a battery capacity measuring device, a terminal and a computer-readable storage medium. By adopting the invention, the measurement efficiency of battery capacity can be improved.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery capacity measurement method, device, terminal and storage medium. Background technique [0002] The battery is an energy device widely used in various fields of life, and the battery capacity is an important characteristic index used to reflect the performance of the battery. In order to obtain the battery capacity, it is necessary to conduct a capacity test on the battery. The existing test method for battery capacity is: use a charge-discharge power supply with a certain precision, conduct a complete charge-discharge cycle test on the battery within a certain current and voltage window, and take the capacity value displayed by the discharge terminal software as the battery capacity. [0003] However, in the process of testing by the existing method, since the capacity of the battery needs to be divided, the equipment cost and time cost of the test are relatively high. [000...
