The electric quantity data of battery cell monitoring managing chip monitoring battery, according to setting battery can supply district determine be
It is no that battery is charged；
The monitoring cell electricity quantity module obtains the electric quantity data of battery according to battery cell monitoring managing chip, and judges battery
State of charge, the state of charge of battery is divided into two kinds according to battery electric quantity：
Battery electric quantity can support complete system data rule operation twice, then be electricity fully charged state, battery electric quantity
Complete system data rule can be supported to operate once, then partly fill state for electricity；
The control of discharge module is according to the state of charge of battery, and control discharge module is in main power source power down, execution phase
The electric discharge setting answered.
During electricity fully charged state, discharge and recharge is carried out according to setting electric current, when electricity partly fills state, according to the one of setting electric current
Half carries out discharge and recharge.
Alternatively, when battery electric quantity state is in electricity fully charged state, if main power source power down, more than 5s, system is at once
Data rule operation is carried out, after the completion of execution, system closedown, if in 5s, main power source frequently power on and off, battery electric quantity
It is reduced to battery electric quantity state and is in electricity and partly fill state, system carries out data rule operation at once, and after the completion of execution, system is closed
Machine.
Alternatively, when battery electric quantity state, which is in electricity, partly fills state, if during main power source power down, system is carried out at once
Data rule operates, after the completion of execution, system closedown.
Alternatively, the battery as backup battery uses lithium battery group.
Alternatively, the main power source uses AC mains-supplieds.
A kind of electric discharge management system based on battery cell monitoring managing chip of the present utility model, is produced compared with prior art
Raw beneficial effect is：
In this patent, monitoring cell electricity quantity module according to battery cell monitoring managing chip obtain battery electric quantity data, and according to
Electricity fully charged state is divided into according to battery electric quantity and electricity partly fills state, why is distinguished, and is because this patent is based on following two
Point：
First, during system operation, battery is set to not be constantly in charged state, when battery is not in full power state
When, when will not be less than a certain numerical value up to reaching full power state, but setting battery electric quantity to battery charging always, just to battery
Charging, otherwise battery, which is constantly in, deep fill the shallow state put and can influence battery life；
Second, battery electric quantity completely fills, partly the state of filling is the influence for considering temperature to battery life to battery electric quantity for setting,
Battery electric quantity fully charged state refers to that partly the state of filling refers to according to setting electric current battery electric quantity according to setting electric current progress discharge and recharge
Half carries out discharge and recharge, and setting electric current is high, and battery temperature is high, can also influence battery life.
This patent realizes the intelligent management to the battery as backup battery, improves the security of battery discharge,
System frequently power supply switching problem caused by upper power-off is avoided, the rule operation of system data is effectively protected, delays
The service life of battery, design reference is provided for related similar functional requirement.
