Automatic charger for lithium battery cluster

Abstract

The invention relates to an automatic charger for a lithium battery cluster. An upper panel of a box body is embedded with a plurality of charging grooves, one side of each charging groove is provided with a fixed metal contact, and three metal contacts correspond to one interface; a power supply concentrator is installed on a middle support panel of the box body, a charging management circuit and a loudspeaker are installed on a lateral panel, and the charging management circuit is connected with the power supply concentrator; the power supply concentrator comprises a restorable fuse, a charging management unit lead connector and a circuit board, a main plug is connected to the charging management unit lead connector through a copper-clad wire on a circuit board via the restorable fuse; the charging management circuit consists of a charging management unit and a detection unit, the detection unit comprises a single chip computer, a voice chip and a communication interface which are connected with the single chip computer, wherein the voice chip is connected with the loudspeaker, the single chip computer is connected with the copper-clad wire on the circuit board of the power supply concentrator through a voltage conversion circuit. The automatic charger realizes the clustering of lithium batteries, and obviously improves the automation degree.

Description

technical field [0001] The invention relates to a full-automatic mechatronics device for simultaneously charging a large number of lithium batteries. Background technique [0002] The high chemical energy density and high battery voltage of lithium-ion batteries make them widely used in portable consumer electronics such as mobile phones. At the same time, lithium-ion batteries also have broad application prospects in terminal products that require frequent mobile use, such as communication terminals in wireless sensor networks. [0003] The application of lithium batteries is inseparable from the matching charger. For example, a linear charger is widely used in mobile phones, which can realize online charging without shutting down. The popular universal charger on the market provides convenience for charging a single battery. However, for a large number or large-scale use of lithium batteries, if a single charger is used, the same number of chargers and AC power strips are...

Problems solved by technology

However, for a large number or large-scale use of lithium batteries, if a single charger is used, the same number of chargers and AC power strips are required, which is extremely inconvenient to operate, especially the universal charging with adjustable metal charging pins When installing the battery, it is necessary to manually adjust the feet to align the metal contacts of the battery, wasting a lot of manpower and material resources
