Problems solved by technology

[0003] In the related art, the charging system of the vacuum cleaner is usually a power adapter with a relatively high output voltage, and cooperates with a battery management system (Battery Management System, BMS for short) in a battery pack to control the charging of the vacuum cleaner through the BMS. However, when When the BMS fails due to abnormal circuit boards and other reasons, it is prone to overcharging, resulting in potential safety hazards during the charging process of the vacuum cleaner.

Abstract

The invention provides a charging control method and a system. The charging control method comprises the following steps: detecting the voltage of a single battery in a battery pack; When the voltagereaches the preset first voltage threshold, controlling the charging control module in the battery pack to turn off the charging of the battery pack; When the voltage reaches a preset second voltage threshold, the control appliance or charger turns off charging of the battery pack, and the second voltage threshold is equal to or greater than the first voltage threshold. The charging control methodand system of the present invention can control the charging of the battery pack by the battery pack, the electric appliance or the charger, so that when the voltage of a single battery in the battery pack is abnormal and the battery management system in the battery pack fails, the electric appliance or the charger can be controlled to stop charging the battery pack, thereby ensuring the safety of the charging process.

Description

technical field [0001] The invention relates to the technical field of electric appliance control, in particular to a charging control method and system. Background technique [0002] The charging time and battery life of vacuum cleaners are important conditions for users to choose chargers. Lithium-ion batteries are widely used in vacuum cleaners due to their high energy density and long cycle life. [0003] In the related art, the charging system of the vacuum cleaner is usually a power adapter with a relatively high output voltage, and cooperates with a battery management system (Battery Management System, BMS for short) in a battery pack to control the charging of the vacuum cleaner through the BMS. However, when When the BMS fails due to abnormal circuit boards and other reasons, overcharging is prone to occur, resulting in potential safety hazards during the charging process of the vacuum cleaner. Contents of the invention [0004] The present invention aims to solv...
