Embodiment Construction

[0026] Since the charging and discharging curves of the energy storage component can be determined by the electrical parameters of itself and the connected current limiting component, different electrical parameters will produce different charging and discharging curves. The following embodiments of the present invention are designed according to the above characteristics, so as to accurately determine the model of the battery, and at the same time, can also determine the temperature of the battery to determine the state of charge of the battery.

[0027] The battery assembly and the charging device of the embodiments of the present invention are used in portable electronic devices, such as mobile phones, personal digital assistants, notebook computers, etc., and the following will take mobile phones as an example to illustrate the present invention Example.

[0028] Figure 3a is a schematic diagram illustrating a battery assembly according to an embodiment of the present in...

Abstract

The invention discloses a battery component. An interface of the battery component connected with a portable electronic device comprises at least three terminals, and the battery component comprises a battery, an identify circuit and a temperature sensing circuit. In addition, the identify circuit comprises an energy storage component and a current limiting component, and the temperature sensing circuit comprises a switch and a temperature sensing component, wherein the impedance of the temperature sensing component is changed along with the temperature of the battery component. The portable electronic device can determine the model of the battery component according to charging line shape generated in the charging of the energy storage component by the current limiting component, and the temperature sensing circuit is started to determine the temperature of the battery component.

Description

technical field [0001] The present invention relates to a battery assembly, and in particular to a battery assembly for portable electronic equipment. Background technique [0002] The battery packs of a portable electronic device (such as a mobile phone, a personal digital assistant, a notebook computer, etc.) can have different models, and are used to provide the energy required for the operation of the portable electronic device. However, before charging the battery pack, it is necessary to determine the model of the battery pack in order to provide a current and voltage that meet the charging specifications of the battery pack of this type for charging. On the other hand, temperature is also an important criterion for judging the current and voltage during charging. If the temperature of the battery components is too high, the charging current should be reduced or the charging should be stopped to avoid damage to the battery due to overheating. [0003] In order to obta...
