Dual-group battery unit charging system for dust collector and charging method of dual-group battery unit charging system

Abstract

The invention discloses a dual-group battery unit charging system for a dust collector and relates to the circuit technology of a charging dust collector. The dual-group battery unit charging system comprises a first battery unit and a second battery unit, which are connected in the dust collector in parallel; a charging end port commonly used by the first and second battery units is connected with a charging seat; the charging loops of the first and second battery units are provided with a charging control module respectively; the charging control modules are connected with a charging processor and can realize the simultaneous charging for the two groups of battery units connected in parallel so the charging efficiency is improved. The invention also discloses a corresponding charging control method, voltage of the two groups of battery units is detected, and the two groups of battery units are charged in constant current and constant voltage mode in sequence, so the charging efficiency and the charging saturation are ensured; when the two groups of battery units have a condition of being more than a preset voltage difference, the charging current can be adjusted to balance the charging time of the two groups of battery units.

Description

technical field [0001] The invention relates to a charging circuit of a vacuum cleaner, in particular to a charging system and a charging method of a vacuum cleaner with double battery packs. Background technique [0002] In a rechargeable vacuum cleaner with a single battery pack, the general charging time for a single battery pack is 4 hours. In order to increase the single use time of the rechargeable vacuum cleaner, there are also rechargeable vacuum cleaners with a double battery pack. The rechargeable vacuum cleaner of the battery pack needs to charge the two sets of battery components twice. After one set of batteries is fully charged for 4 hours, the user manually takes it out from the charging stand, and then replaces another set of battery packs for charging. 8 hours of charging time, the charging time is too long, and when one set of batteries is fully charged, the user needs to manually replace another set of batteries, which increases the user's operating time a...
