Abstract
Provided is a distributed battery management system and method for lead-acid storage battery pack equalization. Multiple lead-acid storage batteries are connected in series to form a series lead-acid storage battery unit. Multiple series lead-acid storage battery units are connected in parallel to form a lead-acid storage battery pack. The output end of the lead-acid storage battery pack is connected with a master control unit. Each lead-acid storage battery is connected with a slave control unit.

The master control unit acquires a maximum voltage signal and a minimum voltage signal of the multiple lead-acid storage batteries. When a voltage difference between the maximum voltage signal and the minimum voltage signal is greater than a preset threshold, the master control unit controls the constant-current/voltage equalization device and the equalization switch to perform equalization operation on the lead-acid storage battery corresponding to the minimum voltage signal. The distributed battery management system and method achieve organic combination of cost and circuit reliability.
Description
Technical field
The invention belongs to technical field of new energies, particularly relate to a kind of distributed battery management system for lead-acid batteries equilibrium and method.
Background technology
In new forms of energy market, lead acid accumulator (comprising plumbous charcoal storage battery) occupies critical role always.Being that chemical energy stores in battery by electric energy conversion when the principle of electrochemical reaction of lead acid accumulator is charged exactly, is electric energy supply external system by chemical energy during electric discharge.
Due to the electrochemical properties of lead acid accumulator itself, it for the overcharging of electric current, cross let pass for and insensitive, generally there will not be burning and explosion phenomenon, this point is different from lithium battery.Therefore, it is generally acknowledged, lithium battery group needs external management or protective circuit, and lead acid accumulator does not need such external management or protection and adopts a kind of extensive style using forestland.
(1) but the quality conformance of lead acid accumulator monomer of batch production be usually difficult to guarantee, such as inner sulfuric acid concentration difference directly affects battery cycle life difference, and this makes each battery cell there are differences in performance; Particularly after battery uses a period of time, the otherness between battery cell is more obvious.
(2), in extensive style use procedure, when certain lead acid accumulator monomer met with and puts, this lead acid accumulator monomer life-span also can be had a strong impact on, and between battery cell, difference is more obvious;
(3) in extensive style use procedure, when certain lead acid accumulator monomer meets with excessive electric current, may accelerate the loose of anode brown lead oxide and come off, this lead acid accumulator monomer life-span also can be had a strong impact on, and between battery cell, difference is more obvious;
(4) in extensive style use procedure, when certain lead acid accumulator monomer meets with and overcharges, internal temperature raises, and have a large amount of gas evolution, positive plate active material may be caused to meet with gas impact and come off, positive grid alloy may suffer anodic oxidation and corrode simultaneously, and this lead acid accumulator monomer life-span also can be had a strong impact on, and between battery cell, difference is more obvious;
(5) under high temperature or cryogenic conditions, in extensive style use procedure, if certain lead acid accumulator monomer carries out work, internal electrical chemical composition is lost, this lead acid accumulator monomer life-span also can be had a strong impact on, and between battery cell, difference is more obvious;
(6) at lead acid accumulator memory period, the self-discharge phenomenon of battery also makes to create a difference between battery cell;
(4) new, old mixed although should prevent lead acid accumulator from having in lead acid accumulator uses, the phenomenon mixed at the new used batteries of many occasions still exists, and causes monomer difference in battery pack obvious;
In sum, when occurring battery cell difference, under the condition not having external management, the performance of whole battery strings will be limited by the poorest battery cell, thus overall service efficiency and useful life are all dragged down.Serious situation, different at the actual load electric current of obvious two Battery packs of difference, because the fuse of whole electric power system Switching Power Supply and battery pack are one to one, excessive and first disconnect with regard to likely having a Battery pack electric current, thereafter another Battery pack also may disconnect because load is excessive, and then it is out of service to cause whole electric power system to be forced to.
The connected mode of many group lead acid accumulators as shown in Figure 1 (for 3 strings 2 and) traditionally, first lead acid accumulator in i.e. series connection group is interconnected to form series connection by both positive and negative polarity, then between whole group of different series-connected cell, just connected, negative negative connects thus forms the parallel connection of whole group, and external discharge and recharge interface is drawn respectively by whole group of total positive pole, total negative terminal.Clearly it is stored in a kind of extensive style " naked use " state, namely without any external management or protective circuit.Therefore in one group of lead-acid batteries, " the poorest " lead acid accumulator module will seriously restrict the performance and used life of whole battery pack, and this " short-board effect " is insurmountable in current lead acid accumulator occupation mode.Can only carry out making regular check on the battery cell replacing poor performance on working service, but cause maintenance workload to increase like this, particularly when using in a large number, maintenance cost is high.
And some research institution is by the mode of lithium battery protection board, the electric discharge of lead acid accumulator and charging process are limited, thus certain protective effect is played to lead acid accumulator, but this can't promotes the overall performance of battery pack;
In addition, some research institution is by the mode of lithium battery management system, equilibrium is carried out to lead acid accumulator, but just as lithium electric management system, they take centralized solution, namely management system as concentrated parts and battery pack completely independent, wire harness is used to connect between them, although this mode can ensure battery management system and battery pack, the division is clearly demarcated, but wire harness is more, this will significantly change the assembling custom of current lead acid accumulator, compactedness and inheritance bad, burden is brought to construction, and the system expandability is bad, namely the battery pack of different string number needs different battery management systems.Although it solves " short-board effect " of battery pack to a great extent, improve whole efficiency and the useful life of battery pack.But, by this battery management system for lithium battery, then seem expensive especially for lead acid accumulator, do not match with cheap lead acid accumulator.
