Problems solved by technology

[0003] Most of the existing hand-held vacuum cleaners are powered by lithium batteries. The lithium battery power supply is the battery life issue that the present invention is most concerned about. Since the battery life of one lithium battery cannot meet the needs of users, the present invention uses two lithium battery packs. To meet the needs of users, this will create a problem - how to charge two lithium battery packs together
At present, some vacuum cleaners are also charging two lithium battery packs, but the existing technology is to use two power adapters to charge two lithium battery packs, which not only increases the cost, but also increases the space occupied by the vacuum cleaner.

Abstract

The present invention provides a charging method for one-charge-two lithium battery packs of a hand-held vacuum cleaner, wherein the sampling resistor of the first lithium battery pack collects the voltage value of each first lithium battery pack, and at the same time the sampling resistor of the second lithium battery pack The resistor collects the voltage value of each second lithium battery pack. When the voltage value of the first lithium battery pack is lower than the voltage value of the second lithium battery pack, the charging voltage of the power adapter automatically matches the voltage value of the first lithium battery pack and Continue to charge the first lithium battery pack; at the same time, when the power chip of the second lithium battery pack detects that the current charging voltage of the power adapter is lower than the actual voltage value of the second lithium battery pack, the charging valve of the second lithium battery pack Automatically shut down, the second lithium battery pack will not be charged at this time. The invention only uses one power adapter to charge two battery packs, which not only reduces space occupation, but also reduces cost.

Description

technical field [0001] The invention relates to a charging method for a lithium battery pack, in particular to a charging method for a one-charge two-type lithium battery pack for a hand-held vacuum cleaner. Background technique [0002] As people's requirements for the quality of life are getting higher and higher, more and more technological products have been integrated into our lives, such as smart phones, smart toilets, mobile mops and vacuum cleaners have become indispensable daily necessities in our lives, and Hand-held vacuum cleaners are an emerging vacuum cleaner product. [0003] Most of the existing hand-held vacuum cleaners are powered by lithium batteries. The lithium battery power supply is the battery life issue that the present invention is most concerned about. Since the battery life of one lithium battery cannot meet the needs of users, the present invention uses two lithium battery packs. To meet the needs of users, this will create a problem - how to ch...
