Title:
STORAGE BATTERY MAINTAINER AND METHOD, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/218316
Kind Code:
A1
Abstract:
A storage battery maintainer and method, and an electronic device. The storage battery maintainer comprises an MCU, a voltage dividing detection module (10), a direct current boost control module (20), a pulse output driving module (30), a power supply module (40), a signal indicating module (50), and a reference voltage generating module (60), wherein the pressure dividing detecting module (10) detects a voltage of a storage battery (BT1) and outputs a corresponding voltage detecting signal; an MCU outputs a first control signal, a second control signal, and a third control signal according to the magnitude of the voltage detecting signal and a reference voltage; a direct current boost control module (20) works when receiving the first control signal, and outputs a corresponding high frequency boost pulse signal; and a pulse output driving module (30) generates a resonance signal and outputs it to the storage battery (BT1) upon receiving the second control signal output from the MCU and the high frequency boost pulse signal. The present invention solves the problem of battery failure caused by a user's inability to know the battery power during a working process of the battery, thereby affecting the normal use of the battery.
