Battery capacity measuring method and device

Abstract

The invention discloses a battery capacity measuring method and device. The battery capacity measuring method includes that a battery measuring platform builds communication connection with a measured battery; the battery measuring platform measures the type of the measured battery; the battery measuring platform finds the data of the measured battery according to the type of the measured battery to obtain the capacity of the measured battery. By means of said mode, the battery capacity measurement is performed through using the battery as the unit, the measuring is precise, the battery can be changed freely, and the maintenance is convenient to perform.

Description

technical field [0001] The invention relates to the field of battery power supply, in particular to a method and device for measuring battery power. Background technique [0002] Batteries (including non-rechargeable batteries and rechargeable batteries) have a wide range of applications. For example, batteries can be used in mobile devices such as electric vehicles, handheld devices and, in the future, wearable devices. [0003] The power state of the battery is a very important physical quantity, which allows the user to have an objective understanding of the remaining power. In the prior art, there are various ways of measuring the battery power of a mobile device. The current method of battery power measurement includes using professional instruments to load the battery, such as using BAT760 to perform load management on the battery, or using a fuel gauge to measure the depth of discharge to obtain energy residual, which can be applied to Coulomb Cumulative electric q...

Problems solved by technology

But the above approach has its inherent limitations:

[0004] 1) The battery management data can only measure the battery capacity and discharge curve under a specific load;

[0005] 2) The external interference variable used for dotting data acquisition is a discrete value difference analysis algorithm. For example, if the battery is dotted at 0°C, 25°C, and 50°C, the dotted data obtained are all discrete, which will have operational errors , will cause inaccurate measurement

[0006] In addition, the current battery measurement platform and the battery are bound, and the maintenance of the battery or the measurement of the battery power is carried out in units of the battery measurement platform.
