Abstract

The invention relates to a battery capacity measuring method and device and equipment. The battery capacity measuring method comprises the following steps: filtering instantaneous open circuit voltageof a battery in a current period to obtain confidence voltage values of the current period; processing capacity intervals corresponding to the confidence voltage values of the current period with a coulometer method to obtain a capacity variation value of the current period; obtaining an accurate capacity value of the current period according to the capacity variation value and boundary capacityvalues of the capacity intervals, and determining the accurate capacity value of the current period as the current capacity of the battery. Based on the open-circuit voltage method and the coulometermethod, the influence of temperature and instantaneous voltage jitter errors and cumulative errors can be effectively reduced, accuracy is improved, so that the battery capacity is measured more accurately, and the fitting effect on real capacity is better.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a method, device and equipment for measuring battery power. Background technique [0002] Power tracking of terminal products is an important topic in the embedded field. How to maximize the use of terminal battery power and protect the integrity of various data of terminal products from being lost due to accidental power failure is an important issue in this field. A major focus of the research. [0003] During the implementation process, the inventors found at least the following problems in the traditional technology: the traditional power calculation method is very sensitive to temperature and voltage fluctuations, which is prone to errors and reduces accuracy. Contents of the invention [0004] Based on this, it is necessary to provide a battery power measurement method, device and equipment for the problem of large errors in traditional power calculation methods.
