Problems solved by technology

[0007] This kind of charging process is only used for normal charging process, but for some abnormal situations in the charging process, especially when some parts of the battery or charger fail, because there is no charging protection, the charging is usually not fully charged. But there is no corresponding prompt; the charging time is very long, and it is always displayed as charging, but the charger is not actually working; it prompts that the charging has been completed, but after a short period of use, the battery display changes from fully charged to unsatisfactory Or prompt to charge soon, etc.

Embodiment Construction

[0033] The present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0034] Please refer to figure 1 , is a structural block diagram of an embodiment of a charging detection device of the present invention, as shown in the figure, the charging detection device includes: a control module 3, and a setting module 1 connected thereto, a detection module 2, a sampling module 4 and Compare module 5.

[0035] Among them, the setting module 1 is used to set charging parameters such as the current full charge voltage of the rechargeable battery, charging critical voltage, rated charging time and maximum charging time, and detection parameters such as detection time, sampling period and times. In an embodiment of the present invention, the charging parameters and detection parameters can be set according to the characteristics of the currently charged battery.

[0036] Among them, the detection module 2 is...

Abstract

The invention discloses a charging detection method and detector of a battery. The method comprises the following steps: setting charging parameters and detection parameters of a rechargeable battery; detecting the voltage of the rechargeable battery, and comparing the detected voltage with the fully charging voltage and charging critical voltage in the set charging parameters; if the conditions are not met, obtaining the charging time of the rechargeable battery, and comparing the charging time with the rated charging time in the preset charging parameters; and if the conditions are not met, determining that a charging fault occurs in the charging process. The method and detector provided by the invention can be used for detecting the charging fault in the process of charging the battery.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery charging detection method and a charging detection device. Background technique [0002] With the continuous development of communication technology, more and more wireless terminal devices have entered people's lives. Due to the requirements of portability and mobility, these wireless mobile terminal devices often need to be powered by built-in or external batteries. , these batteries are charged through the charger. The charging principle and process of the prior art are generally as follows: [0003] 1) In the constant current charging stage, the charging current of the charger remains constant, the charged power increases rapidly, and the battery voltage rises; [0004] 2) In the constant voltage charging stage, the charging voltage of the charger remains constant, the charging power continues to increase, the battery voltage rises slowly, and the charging current drops; ...
