Problems solved by technology

The battery backup unit (Battery Backup Unit, referred to as BBU) of the storage product requires the lithium battery to be in a fully charged state when it leaves the factory. Since the lithium battery will lose power during storage after the lithium battery is fully charged, the lithium battery in the prior art is not installed before assembly. Guaranteed to be fully charged

Abstract

The invention relates to a lithium battery charging device and method and a lithium battery. The device comprises a single-chip microcomputer, a control circuit and an anti-surge circuit, wherein thesingle-chip microcomputer is used for detecting the electric quantity of a lithium battery in real time and sending a charging command through a system management bus when the electric quantity is notfull; the control circuit is used for receiving the charging command sent by the single-chip microcomputer, converting the voltage input through an adapter according to the charging command and thenoutputting the converted voltage; and the anti-surge circuit is used for stabilizing the voltage output by the control circuit and then charging the lithium battery until the lithium battery is fullycharged. According to the scheme, the electric quantity of the lithium battery can be detected in real time, charging of the lithium battery is controllable, and it is effectively guaranteed that thelithium battery is continuously in a full-electric-quantity state.

Description

Technical field [0001] The present invention relates to the field of lithium batteries, in particular to a lithium battery charging device, method and lithium battery. Background technique [0002] Lithium batteries are widely used in storage and other products due to their large capacity, small size, and high safety. The assembly cycle of the complete machine for storing products is too long, and the lithium battery is installed into the complete machine as the final assembly device. The battery backup unit (BBU) of the storage product requires the lithium battery to be in a fully charged state when leaving the factory. Since the lithium battery is fully charged, the power will be lost during storage. Therefore, the lithium battery in the prior art is not assembled before assembly. It can ensure that the power reaches the fully charged state. Summary of the invention [0003] In view of this, it is necessary to provide a lithium battery charging device, method and lithium batte...
