Description
Technical field
The utility model relates to new energy field of battery management, in particular to a kind of smart battery system.
Background technique
Battery has been used widely since utility model, especially using lithium battery as the application of the motive-power battery of representative
Range is more and more wider, even expands to household energy storage from industrial energy storage, electric vehicle.Although being widely applied,
The status assessment for being single battery and series connection are in groups using the thing for always being one more professional (difficulty, Gao Chengben).Than
The remaining capacity (SOC) for such as saying battery is just known after needing the discharge instrument constant-current discharge with profession, but has not at this moment had to application
It is significant, because electricity has been bled off；The health degree (SOH) of battery is said for another example, and even more difficulty has an equipment can be straight
Connect measurement.How its residual capacity and health degree easily can quickly be known with a low cost, and this problem is always
Without solution.In power type application, battery is usually all multiple uses that are together in series, in use, the inconsistency of battery
It is continuously subject to deteriorate and one influences the big problem used, most of battery usually occur, there are also electric but because of certain a string of battery
The case where causing whole group battery not to be available out of power.If can solve these problems from engineering, each battery both can be with
When with user carry out data interaction, and can be convenient the balanced energy that is cascaded (active equalization, i.e., to whole group battery come
Say, can accomplish effect of the energy transfer to low energy battery of high energy battery) solve the problems, such as that inconsistency is (even electric
The battery that amount is different from, which can be cascaded, uses each battery out of power simultaneously), then from independent a string of batteries
From the perspective of, this battery is exactly intelligent because it can allow user easily to know the state of battery, can also and its
His battery is connected into group and automatic positive energy exchange to guarantee the whole group longest working time.The largest benefit of intelligent battery is battery
Normal cell, either industrial application or civilian can be become, the difficulty and cost used in groups can be substantially reduced.
In the prior art, also have that solve the problems, such as that battery is used in series by the method for energy transfer inconsistent.But it is existing
Some technologies have 3 defects, and first defect is battery when splitting into individually connectionless state from state in groups, each battery
Data can not battery locally obtain；Second is to need to know the string number for wanting stack battery in advance, then according still further to this string
Number customization circuit kit just adapts to this battery pack, that is to say, that battery can not adaptively in groups；Third defect is to increase
Relevant battery management unit (circuit) is added to need to customize, line is numerous, can not standardize.Three above defect makes in battery
In application, higher cost is operated and paid there is still a need for professional and mechanism, the function of intelligent battery cannot achieve.Such as
It says the battery of electric car, is exactly fuel tank gasoline referring to fuel vehicle, it should it is the acquisition that can be convenient of standard, but current nothing
Method is realized, the electric vehicle of which brand has been selected, just it is necessary that can not be replaced with its matched battery pack；And if using intelligence
Energy battery, as long as same model, so that it may it is convenient to exchange.Besides the retired battery of electric car (SOH 70% or so,
Electricity after i.e. fully charged is nominal 70%), at present can not echelon utilize because groups of cost has been more than with new electricity again
Pond can only scrap recovery processing, waste resource.And if using intelligent battery, so that it may pick out available battery rapidly, side
Just recombination reduces the cost that echelon utilizes, has saved resource.
Thus the prior art could be improved and improve.
