Problems solved by technology

[0004] To avoid shortening the battery life, a small charging current can be applied to the battery to perform charging at a normal speed. Although this can prevent the battery from aging too quickly and prolong the battery life, it may cause the charging to be too slow and cause inconvenience to the user

Abstract

A battery charging system and a battery charging method are provided. The battery charging system includes a control unit, a charging unit, and a measurement unit. The control unit is configured to generate and output a control signal. The charging unit is coupled to the control unit and a battery. The charging unit is configured to receive the control signal, generate a charging current accordingto the control signal, and output the charging current to charge the battery. The measurement unit is coupled to the battery and the control unit. The measurement unit is configured to measure a battery voltage output by the battery, and output a measurement signal to the control unit. The measurement signal corresponds to the battery voltage.

Description

technical field [0001] The invention relates to a battery charging system, in particular to a battery charging system capable of adjusting the charging current according to the internal resistance of the battery. Background technique [0002] Rechargeable batteries are often used in portable devices, such as notebook computers, mobile phones, tablet computers, etc., and their applications can be seen. At present, some rechargeable batteries can withstand a larger charging current to support fast charging. [0003] For example, if a larger charging current is applied to the battery, fast charging can be achieved, thereby improving the convenience of use. However, if a large charging current is applied to the battery, the aging of the battery may be accelerated. If the aging degree of the battery has reached a predetermined level, if a large fast charging current is still applied, the overall service life of the battery will be shortened. [0004] To avoid shortening the ba...
