Smart battery management method and system

Abstract

The present invention discloses a smart battery management method and system. The method comprises: performing starting and initializing a MCU function module to allow each module to perform normal work; performing initialization of external auxiliary devices, obtaining correction voltage through MCU, and triggering a request of communicating a smart battery to the MCU through wakeup interruption; completing the communication connection with the MCU and the smart battery through a serial communication processing function through the MCU; obtaining voltage and current reference information of the smart battery through the MCU, and obtaining the information the number of times of smart battery charging according to the current direction of the battery; and allowing the MCU to enter a power saving mode to keep the communication connection with the smart battery and wait for the arrival of an interruption event so as to execute an interruption event. The smart battery management method and system employ the MCU unit to detect the output current and voltage parameters of the smart battery, calculate the residual capacity of the smart battery and perform output voltage calibration, charging record query, host and slave management, system power consumption management and UART communication management so as to realize monitoring of the user performance and number of usage times of the smart battery.

Description

technical field [0001] The present invention relates to the technical field of intelligent batteries, in particular to an intelligent battery management method and system. Background technique [0002] Compared with lead-acid batteries, lithium batteries have the advantages of environmental protection, long life, and high energy density, and are gradually replacing lead-acid batteries. However, lithium batteries are relatively fragile. When the battery is overcharged or overdischarged, it will damage the battery or even catch fire, so it is necessary to protect the circuit. In actual use, the situation of over-discharge is more complicated, because of the existence of battery self-discharge, users are required to recharge the lithium battery every three months when they do not use it for a long time, and forgetting to charge it will become the cause of lithium battery damage. main reason. The traditional lithium battery protection board does not have the function of histor...

AI Technical Summary

Problems solved by technology

In actual use, the situation of over-discharge is more complicated. Because of the self-discharge of the battery cell, users are required to charge the lithium battery once every three months when they do not use it for a long time, and forgetting to charge it will become the cause of damage to the lithium battery. main reason

The traditional lithium battery protection board does not have the function of history recording. After the lithium battery is damaged, it is impossible to determine the cause of the damage, which leads to losses for dealers or manufacturers.
