Protector for battery charge-discharge control circuit for note-book computer

Abstract

The invention discloses a protection device of charge-discharge control circuit of the cells of the notebook PCs. The charge-discharge control circuit includes main control circuit used in setting the voltage of the charge-discharge current and reading the parameters of the cells, the safeguard protection circuit in packing the cells and the switch for the on-off of the circuit set between the charge-discharge electric current supply base pin of the control interface and the clock signal base pin. The invention increases the switching key of the cell and can cut off the loop used by the cells conveniently and quickly without removing the cell. The function and design is more humanized and resolves the problem of alternating charge and discharge.

Description

technical field

[0001] The invention relates to a protection device for a charge and discharge control circuit of a notebook computer battery. Background technique

[0002] A rechargeable battery is generally provided in a notebook computer, and the rechargeable battery is generally a lithium-ion battery with better performance. Since the service life of a lithium-ion battery is related to its charge and discharge times, effectively controlling its use times can prolong the service life of the battery. There are two power supply methods for notebook computers, namely adapter power supply and battery power supply. In use, the two are often used interactively. In many cases, the battery starts to charge before it is completely discharged, but this is also counted as one charge. Careful people who use laptops often unplug the battery to reduce the number of times the battery is used. Since the laptop battery is generally made into a built-in or part of the laptop structure, un...
