Embodiment 1

[0036] Such as figure 1 As shown, an intelligent charging method provided by an embodiment of the present invention includes: detecting the battery temperature value and battery voltage value of the battery to be charged in real time; dynamically adjusting the charging voltage value according to the obtained battery temperature value and the battery voltage value and charging current value.

[0037] Specifically, when the underwater electronic product shows that it needs to be charged, the smart charging device starts to detect the smart battery, and obtains the temperature value and voltage value of the corresponding register of the battery to be charged through SMBUS / I2C. The detection needs to go through a certain period of time. Ensure that the detected temperature and voltage are constant and accurate, so as to obtain the battery temperature value and battery voltage value of the battery to be charged, and store the battery temperature value and battery voltage value in t...

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...
