Abstract

The present invention relates to the field of charging, and in particular relates to an intelligent charging method and device, and the method is as follows: detecting a battery temperature value and a battery voltage value of a battery to be charged in real time; and dynamically adjusting a charging voltage value and a charging current value according to the obtained battery temperature value and the battery voltage value. Through the cooperation of the intelligent charging device and a smart battery, real-time voltage and temperature data of a battery terminal can be obtained by SMBUS / I2C communication, and an output constant current value and a charging limit voltage value can be flexibly set, so that safe and effective charging of lithium batteries at low temperature and high temperature can be more optimized.

Description

technical field [0001] The invention relates to the charging field, in particular to an intelligent charging method and device. Background technique [0002] After the energy of the battery is consumed by discharge, it can be recovered by charging and can be discharged again to form a charge-discharge cycle. Usually charged with direct current. In different situations, different charging methods such as constant current charging, constant voltage charging, floating charging, trickle charging, rapid charging or a combination of these methods are used. [0003] According to the formula of power=voltage*current*time, when the power is fixed, the charging time can only be shortened by increasing the voltage or current. [0004] High-voltage charging: high-voltage low-current mode, to increase the voltage, it is necessary to design multiple step-down circuits in the charging circuit. When charging, the charging device will generate heat, and the battery will also generate heat...
