Title:
BATTERY CHARGING DEVICE, METHOD AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/014486
Kind Code:
A1
Abstract:
A battery charging device, comprising a resistor array module (30), a resistor array control module (40), a detection module (20), and a main control module (10).The resistor array module (30) is electrically connected with the resistor array control module (40) and the detection module (20) respectively, and the main control module (10) is connected with the detection module (20) and the resistor array control module (40) respectively. When a battery is charged according to a preconfigured first charging temperature threshold, after determining a target resistor array according to the first charging temperature threshold, the main control module (10) controls the resistor array control module (40) to turn on the target resistor array in the resistor array module (30) and receives a comparison result of a partial pressure value in the detection module (20) and a partial pressure value of the target resistor array obtained by the detection module (20) to determine whether the temperature of the battery reaches the upper limit or the lower limit of the first charging temperature threshold. If yes, the main control module controls the resistor array control module (40) to be switched to turn on a resistor array corresponding to a preconfigured second charging temperature threshold in the resistor array module (30). The charging device improves the battery charging efficiency.
