Title:
アダプター及び充電制御方法
Document Type and Number:
Japanese Patent JP6623237
Kind Code:
B2
Abstract:
An adapter (10) and a charging control method, the adapter (10) comprising: a power conversion unit (11), used for converting an inputted alternating current so as to obtain an output voltage and an output current of the adapter (10), the output current of the adapter (10) being an alternating current or a pulsed direct current; a voltage holding unit (12), an input end of the voltage holding unit (12) being connected to the power conversion unit (11), the voltage holding unit (12) being used for obtaining an input voltage having a pulsed waveform from the power conversion unit (11) and converting the input voltage having the pulsed waveform into a target voltage, an output end of the voltage holding unit (12) being connected to a device in the adapter (10), the target voltage being used to power the device in the adapter (10), a peak value of the target voltage being between the lowest operating voltage and the highest operating voltage of the device. The adapter (10) reduces lithium separation in batteries, and increases the service life of batteries.
