Abstract

The invention discloses an intelligent charging apparatus for a lithium battery pack. The intelligent charging apparatus comprises a shell, a dummy panel, an interface board, a temperature sensor, an insulating sleeve, a touch display screen, a power supply switching key and a lower bracket, wherein jacks are formed in side boards; the insulating sleeve is arranged in the jacks in a sleeving manner; a power supply module is arranged on the inner side of the lower bracket; the power supply module is used for converting an alternating current into a constant-voltage direct current; the interface board is mounted on the dummy panel; a socket in the interface board extends out of the insulating sleeve; a control board is used for circuit switching and current detecting; the temperature sensor, which is used for monitoring the temperature of a radiator and displaying the temperature through the touch display screen, is mounted on the radiator; and balance resistors are mounted on the two sides of the radiator. By adoption of the portable charging apparatus for the lithium battery pack, rapid charging of multiple lithium battery packs can be realized; and meanwhile, the charging apparatus is high in charging efficiency, long in service life, compact in structure, and high in safety and reliability.

Description

technical field [0001] The invention relates to the technical field of portable charging devices, in particular to the technical field of a charging device for an intelligent lithium battery pack. Background technique [0002] With the development of science and technology, lithium battery chargers are used more and more widely. Lithium battery chargers have been widely used in mobile phones and digital fields, but the batch application of power lithium batteries has only started in recent years. Lithium batteries have many advantages such as recyclability, pollution-free and high energy density. Due to the limitation of manufacturing process and technology, there are inevitable differences in the capacity, voltage and internal resistance of each single battery in the power battery pack. As the number of cycles increases, this difference gradually increases, which will eventually lead to premature failure of the battery pack. In order to reduce the inconsistency of the cap...
