Embodiment 1

[0028] Embodiment 1 of the present invention firstly provides an anti-fluctuation battery power detection method, such as figure 1 shown, including the following steps:

[0029] S1, continuously collect battery voltage multiple times to obtain multiple voltage value data; the collection interval is 1-100 milliseconds;

[0030] S2. Calculate the difference between the two voltage values ​​before and after the collected voltage value data to obtain the voltage amplitude. If the voltage amplitude exceeds the set amplitude threshold, it is judged that the battery is in the load impact stage, and the voltage value in this stage is invalid data, and Filter out the invalid data; otherwise, it is judged that the battery is in a stabilization stage, and the voltage value in this stage is valid data;

[0031] S3, judging whether the battery is in a low power state according to the valid voltage data.

[0032] Such as Figure 4 As shown, the moment the electrical switch is turned on, ...

Embodiment 2

[0055] Embodiment 2 of the present invention provides an anti-fluctuation battery power detection device, which adopts the anti-fluctuation battery power detection method provided in Embodiment 1, such as image 3 shown, including:

[0056] A voltage acquisition unit, used to acquire battery voltage value data;

[0057] The data processing unit calculates and processes the voltage value data collected by the voltage acquisition unit, excludes the voltage value data in the battery load impact stage, and takes the voltage value in the stabilization stage as valid data;

[0058] The power judging unit judges whether the battery is in a low power state according to the valid data provided by the data processing unit;

[0059] The storage unit is used to store the voltage data of the voltage acquisition unit, and the data processing unit calls the voltage data in the storage unit for calculation and processing.

[0060] In this embodiment, the storage unit is preferably a registe...

Abstract

The invention discloses an anti-fluctuation battery electric quantity detection method and device; wherein the method comprises the following steps: S1, continuously collecting the voltage of a battery for many times to obtain a plurality of voltage values, wherein the acquisition interval time is 1-100 milliseconds; S2, calculating a difference value between the two voltage values to obtain a voltage amplitude, if the voltage amplitude exceeds a set amplitude threshold value, judging that the battery is in a load impact stage, determining that the voltage value in the stage is invalid data, and filtering out the invalid data, otherwise, judging that the battery is in a stable stage, wherein the voltage value in the stage is valid data; and S3, judging whether the battery is in a low electric quantity state or not according to the effective voltage data. The battery electric quantity detection device comprises a voltage acquisition unit, a data processing unit, an electric quantity judgment unit and a storage unit. According to the invention, the situation of low-electric-quantity false alarm caused by large voltage fluctuation due to battery load impact can be prevented, the accuracy of battery low-electric-quantity detection is improved, and the influence on normal power utilization work is avoided.

Description

technical field [0001] The invention belongs to the technical field of battery power supply, and in particular relates to an anti-fluctuation battery power detection method and device. Background technique [0002] In a battery-powered system, when the battery power is too low, it will affect the normal operation of the electrical equipment. Therefore, it is necessary to detect the battery power in real time to determine whether the battery power is too low. However, in daily work, the moment the electrical switch is turned on, it is easy to cause false alarms of low battery power. Contents of the invention [0003] In order to solve the above-mentioned problems and deficiencies in the prior art, the purpose of the present invention is to provide a battery power detection method and device for anti-fluctuation, which can prevent false alarms of low battery power and improve the detection accuracy of low battery power. [0004] In order to achieve the above object, the pre...
