Problems solved by technology

At present, the self-learning of the smart battery must be carried out during the use of the notebook, because it takes more than 8 hours for the smart battery to complete a complete capacity self-learning, which takes too long
If the laptop is powered off during the self-learning process of the smart battery, this self-learning will not be completed, and the next battery self-learning process needs to be restarted.
Moreover, when the battery is performing self-learning when the notebook is working, since the load is constantly changing, the discharge current will also change accordingly, resulting in a decrease in the accuracy of self-learning

Embodiment Construction

[0027] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0028] The embodiment of the invention is a charger device. In view of the current charger, the self-learning function of the smart battery cannot be performed. Therefore, a discharge circuit is added in the charger to complete the self-learning function of the smart battery.

[0029] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Such as figure 1 As shown, it is a schematic diagram of a charger 11 device according to an embodiment of the present invention, including:

[0031] adapter interface 12;

[0032] A battery interface 13, connected to the smart battery 110, for connecting the smart battery;

[0033] The judging unit 14 is connected to the smart...

Abstract

The invention provides a charger. In order to solve the problem that the prior charger cannot carry out self-learning calibration on an intelligent battery, the charger is provided, wherein the charger comprises an adapter interface, a battery interface, a management module which comprises a control unit used for reading first information of the intelligent battery and sending a control signal according to the first information, a charging circuit for charging the intelligent battery when the control signal is a charge signal, a discharging circuit for discharging the intelligent battery when the control signal is a discharge signal and a hardware key for controlling the intelligent battery to enter a self-learning state, wherein the discharge circuit is constant load used for providing constant current or voltage for the intelligent battery. After the charger is adopted, a user can solve the self-learning process of the intelligent battery when using the charger and does not need to connect the intelligent battery to a notebook for self-learning.

Description

technical field [0001] The invention relates to the battery field, in particular to a charger for an intelligent battery. technical background [0002] A smart battery is a modern portable electronic device, and it is commonly used in smart handheld devices such as mobile phones, notebook computers or PDAs. Since the user uses the battery in different scenarios, and the capacity that the battery itself can store or release each time is also related to factors such as temperature and current, the battery capacity that the user sees in the system and the actual capacity of the battery will vary. error occurs. At present, the self-learning of the smart battery must be carried out during the use of the notebook, because it takes more than 8 hours for the smart battery to complete a complete capacity self-learning, which is too long. If the laptop is powered off during the self-learning process of the smart battery, this self-learning will not be completed, and the next battery...
