Intelligent cell charging system and control method thereof, and intelligent cell device

Abstract

The invention discloses an intelligent cell charging system and a control method thereof, and an intelligent cell device. The intelligent cell charging system comprises an intelligent cell, a charger and a protection apparatus. The protection apparatus is connected between the intelligent cell and the charger. The protection apparatus is communicated with the intelligent cell so as to acquire state information of the intelligent cell, monitors work state information of the charger, determines that the intelligent cell generates an abnormity during a charging process according to the state information of the intelligent cell and/or determines that the charger generates an abnormity during the charging process according to the state information of the intelligent cell and the work state information of the charger and then disconnects charging connection between the intelligent cell and the charger. By using the intelligent cell charging system of embodiments in the invention, through arranging the protection apparatus, charging states of the intelligent cell and the charger can be monitored in real time and charging safety of the intelligent cell is ensured.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an intelligent battery charging system, an intelligent battery device, and a control method for the intelligent battery charging system. Background technique [0002] With the widespread use of lithium batteries, more and more batteries have been added to the Battery Management System (Battery Management System), and it shows a tendency to be intelligent. In related technologies, a battery with a microcontroller and a battery management system is usually called a smart battery. The smart battery system can monitor its own voltage, current, power, temperature and other information in real time, and can automatically protect when the battery fails. For example, when charging, if the smart battery monitors abnormal conditions such as excessive temperature, abnormal voltage, or excessive current, it will automatically disconnect the charger and stop charging to ensure safety.

AI Technical Summary

Problems solved by technology

[0003] Regardless of whether it is an ordinary battery or a smart battery, the battery and the charger are directly connected during the charging process of the battery, and the battery and the charger cannot know the actual working conditions of each other. If the temperature of the battery is too high during the charging process, or the voltage Too high and other abnormal conditions, and the charger cannot know the abnormal condition of the battery and continue to charge, it is very easy to catch fire or even explode

In practical engineering applications, even if the smart battery has a certain self-protection ability, the smart battery itself is controlled by a microcontroller. If there is an abnormality or crash, the smart battery will completely lose its protective function just like ordinary batteries.
