Battery in-situ test method and device and battery charge system

Abstract

An embodiment of the invention provides a battery in-situ test device. The battery in-situ test device is characterized in that a test trigger module tests charge current from a battery end and triggers a logic control module when the charge current is smaller than a preset current threshold; the logic control module shuts down the battery charge system and directs a charge-discharge balance module to charge and then discharge the battery end; during discharge operation, a test judgment module tests voltage of the battery end and judges whether the voltage of the battery end is smaller than preset test voltage or not; if yes, a battery is judged being not in situ; if not, the battery is determined being in situ. The embodiment further provides a battery charge system and a battery in-situ test method. Through the application of the embodiment, the battery can be automatically tested in situ with no external elements, and charge efficiency is unaffected during the test process.

Description

technical field [0001] The invention relates to the technical field of battery detection, and more specifically, to a battery presence detection method, device and charging system. Background technique [0002] At present, battery-powered electronic devices (especially mobile electronic devices, such as smartphones, tablets, laptops or portable instrument lights) are widely used in people's daily life. These electronic devices usually have battery charging and discharging control systems, Because the battery is sometimes disconnected due to faults or artificially plugged in and out, if the battery presence cannot be detected in time, it will have a potential impact on the normal operation of the system. Contents of the invention [0003] Embodiments of the present invention provide a battery presence detection method, device and charging system to detect whether the battery is in place. [0004] In the first aspect, a battery in-position detection device is provided, whic...
