Battery charging method and system

Abstract

The invention provides a battery charging method. The method at least comprises the following steps: step one, a monitoring module monitors whether a battery is correctly placed on the charging position and whether the connection is correct; step two, the monitoring module controls the on and off of a charging circuit and controls to start a power supply module to output charging voltage for charging the battery; step three, after charging, the monitoring module controls the power supply module to stop outputting voltage, and controls a switch open circuit of the charging circuit. The invention also comprises a power supply charging system for implementing the method. After the battery is connected correctly according to output, the charging system is started up, so that the problem that a battery and a charging device are damaged because of battery reversal can be prevented, and energy output by a system under the condition of battery reversal or no battery is also prevented; meanwhile, a selector switch in the charging system provided by the invention can exchange under the condition that current is lower than the preset value, and the service life of the selector switch is prolonged.

Description

technical field [0001] The invention relates to the charging field, in particular to a battery charging method and system. Background technique [0002] With the development of electronic technology, the application of batteries is becoming more and more extensive. Batteries, including primary batteries (also known as: primary batteries), are discarded after discharge, such as common dry batteries; batteries (also known as: secondary batteries) can be charged to activate active substances and continue to be used after discharge, such as common Lithium Ion Battery. In a chemical battery, the direct conversion of chemical energy into electrical energy is the result of spontaneous chemical reactions such as oxidation and reduction inside the battery, which are carried out on the two electrodes respectively. The negative electrode active material is composed of reducing agents with relatively negative potential and stable in the electrolyte, such as active metals such as zinc,...
