Battery charging device with dynamic capacity-display and charge countdown functions and application thereof

Abstract

The invention relates to a battery charging device with dynamic capacity-display and charge countdown functions and an application thereof, wherein the device comprises a main controller, a charge control circuit, a voltage collecting module, a current collecting module, a temperature detecting module, a protective circuit module, a working state indicating module, a display module and a power supply converting module used for supplying power to other modules. The main controller is respectively connected with the charge control circuit, the voltage collecting module, the current collecting module, the temperature detecting module, the protective circuit module, the working state indicating module and the display module. The application of the battery charging device is as follows: after being powered and initialized, the main controller dynamically collects parameters of a battery via the voltage collecting module, the current collecting module and the temperature detecting module, calculates the actual capacity of the battery and displays the actual capacity via the display module, and the like. Compared with the prior art, the invention has the advantage of capability of displaying the actual capacity of the battery and the electric quantity charged in the battery, the function of charge countdown estimation, and the like.

Description

technical field [0001] The invention relates to a battery charging device and its application, in particular to a battery charging device with capacity dynamic display and charging countdown and its application. Background technique [0002] With the rapid development of science and technology, secondary batteries are widely used in various fields. Qualified batteries on the market will be marked with rated capacity, but with the aging of the battery and different working conditions, the rated capacity cannot reflect the actual performance of the battery very well, so it is very necessary for users to understand the actual capacity of the battery used; secondly , for the same battery (group), there is a great correlation between the amount of electricity that can be released and the amount of electricity that can be charged. Therefore, the amount of electricity charged is an important indicator to measure the battery life performance. The working capacity of the battery is ...

Problems solved by technology

[0003] The charger is a special device for supplementing battery energy, but the chargers currently on the market generally only have two basic status displays of charging and full, and do not have the display function of the above parameter information. The shortcomings of this type of charger can be The summary is as follows: (1) The user cannot obtain the actual capacity of the battery used, and cannot make an accurate judgment on the battery performance; (2) The power charged into the battery cannot be displayed, and the user cannot know the actual energy storage status of the battery; (3) ) cannot display the battery charging speed and the time required for full charging, and the user cannot understand the battery charging process
