Problems solved by technology

In the prior art, the charger is generally directly coupled to the electric appliance without the intelligence to control the charging and discharging of the battery. It is impossible to adjust the charging and discharging parameters of the battery according to the load or the performance of the battery, and it is impossible to monitor important parameters such as the temperature and voltage of the battery. It is easy to produce overshoot or deep discharge, which greatly affects the service life of the battery and the number of charge and discharge times, and it cannot be protected in time if there is an abnormal situation

Description

technical field [0001] The invention relates to the technical field of battery charging and discharging, in particular to a battery charging and discharging control system for a handheld electric appliance. Background technique [0002] At present, most portable devices use lithium batteries as backup batteries, and the service life of lithium batteries has a great relationship with the number of times the batteries are charged. However, most portable devices do not control the charging of the lithium battery. For example, when the power adapter is connected to an external AC power, the lithium battery will automatically charge, and the power of the lithium battery at this time is likely to be sufficient to maintain the operation of the portable device. For a long time, this may reduce the service life of the battery due to the increase in the number of charging of the lithium battery. [0003] On the other hand, hand-held electric tools such as vacuum cleaners, electric dr...
