Description
Technical field
The utility model relates to a kind of novel equalizing charge of battery management system.
Background technology
A present group storage battery system to being in series by many storage batterys; Charger that it was equipped with and battery protection system only charge to whole group storage battery and protect; Can only guarantee that in use the total voltage value of whole group storage battery is not higher than the maximum voltage value that overcharges, be not less than the minimum voltage value that overdischarge takes place; And all batteries for batteries are put with filling together, can't realize single battery is managed separately effectively.On the other hand, because the inhomogeneities of performances such as the internal resistance of single storage battery, self discharge, capacity, in use; Particularly when limiting voltage uses; Indivedual storage batterys can overcharge or the situation of overdischarge, and the time one is long, and these batteries will damage in advance; Battery after the damage can influence other storage batterys again, thereby causes the whole group storage battery can't operate as normal.Therefore, how whole batteries and single storage battery are separately managed and become the problem that urgent need will solve.
Summary of the invention
For avoiding the deficiency of above prior art, the utility model proposes a kind of novel battery charging management system, to solve whole batteries and single storage battery Charge Management independently.
The technical scheme of the utility model is:
A kind of novel equalizing charge of battery management system; This system comprises batteries, battery automatic switching control equipment, battery voltage detector, charging device and programmable logic controller (PLC); Described batteries is connected with voltage check device and charging device respectively through the battery automatic switching control equipment, and this voltage check device is connected with described programmable logic controller (PLC) with charging device.
Described batteries is a valve controlled sealed lead-acid accumulator.
The utlity model has following advantage:
A kind of novel equalizing charge of battery management system of the utility model; Can realize every in batteries storage battery is carried out boost charge respectively; Native system is set a boost charge unit simultaneously; Can carry out boost charge separately through switching to each storage battery, thus the capacity that reaches each storage battery all dress to the heap(ed) capacity battery, and make that capacity difference minimizes between battery; This compensation process can guarantee that single storage battery and whole group storage battery all can not overcharge and overdischarge the useful life of having improved batteries greatly.

Embodiment
As shown in Figure 1; Present embodiment provides a kind of novel equalizing charge of battery management system; This system comprises batteries, battery automatic switching control equipment, battery voltage detector, charging device and programmable logic controller (PLC); Described batteries is connected with voltage check device and charging device respectively through the battery automatic switching control equipment, and this voltage check device is connected with described programmable logic controller (PLC) with charging device.Described batteries is a valve controlled sealed lead-acid accumulator.
The utility model is when carrying out battery charging management, and battery voltage detector carries out voltage detecting to each storage battery of batteries.At first first storage battery inserts battery voltage detector automatically, if the voltage of this storage battery is lower than the maximum battery voltage that checkout gear detects, then storage battery inserts charging device automatically and charges.When the charge in batteries voltage that is recharged reached the magnitude of voltage of setting, native system excised first storage battery through the battery automatic switching control equipment automatically, and second storage battery inserted native system.Like the voltage of first storage battery maximum battery voltage value more than or equal to battery voltage detector; Then first battery excised and second same operation of storage battery access carrying out through the battery automatic switching control equipment; Storage batterys all in the batteries is all detected charging accomplishes always; Finish to replenish for the first time electricity, and can start circulation next time automatically according to the blanking time of default.Programmable logic controller (PLC) carries out record to each battery charging process, and the cycle that each storage battery is detected is provided with.
Be depicted as single storage battery boost charge electrical schematic diagram like Fig. 2,3.Batteries is made up of 18 100AH/12V valve controlled sealed lead-acid accumulators.KA2 is that high voltage detects output relay, promptly when detecting certain cell voltage and be higher than set point, and this relay closes, output dry contact signal is to PLC; KA3 is that low-voltage detects output relay, promptly when detecting certain cell voltage and be lower than set point, and this relay closes, output dry contact signal is to PLC.
1KA1 to 18KA1 is the voltage detecting relay, after being connected in order by 1KA1 to 18KA1, respectively 1# to 18# battery is carried out voltage detecting.
Self check after system powers on after 1 minute, begins the 1# battery is detected, and promptly 1KA1 is closed, is higher than set point if detect voltage, and detection module triggers KA2, sends the high signal of detection voltage, after 5 seconds the 2# battery is carried out voltage detecting; Be lower than set point if detect voltage, detection module triggers KA3, sends the detection voltage low signal; And PLC sends charging signals, and 1KM connects, to the 1# battery charge; When charging reached set point, detection module triggered KA2, the charging of 1KM outage stopping to the 1# battery; By that analogy, go down one by one until 18# battery detecting (or charging finish), system accomplishes once detection or the charging work to 18 batteries.PLC noted 18 batteries was carried out one-time detection and charging work this moment; Regularly after 1 week (promptly 604800 seconds); Once more the 1# battery is begun to carry out voltage detecting, the detection and the charging work of a beginning new round, promptly system is with the continuous periodic duty of the time interval in a week.
Obviously, the foregoing description of the utility model only be for explain clearly that the utility model does for example, and be not to be qualification to the execution mode of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here can't give exhaustive to all execution modes.Conspicuous variation that every technical scheme that belongs to the utility model is extended out or change still are in the row of the protection range of the utility model.
