Description
Technical field
The present invention relates to use storage battery to carry out the field of low-voltage DC supply, particularly relate to and a kind of single group storage battery or plurality of groups of storage batteries are discharged and recharged the manager of integrated management and use management system, the management method that this manager is controlled.
Background technology
Storage battery has voltage to be stablized, powers reliably, is widely used in each departments such as power plant, communication system, electric automobile, Aero-Space, vessel traffic.In numerous areas, storage battery significant feature one is to use as starting power supply; The 2nd, use as stand-by power supply.For example: have a large amount of power consumption equipments to power on the naval vessel by the dc low-voltage system, when main generator and emergency generator fault, must be by low-voltage power supply system to power devices, therefore the low-pressure system that is made of batteries is the equipment that must be equipped with on all naval vessels.
Existing startup batteries on naval vessels has A, the B-battery group used as stand-by power supply again.Batteries is carried out the charging device of management of charging and discharging and normally install concentratedly below cabin, the installation of batteries relatively disperses, and has below the cabin and on the clamping plate, and batteries is charged and the circuit that discharge has and grows, has weak point.Many auxiliary power generation units are arranged under cabin, and their startup is finished by storage battery.When repeatedly startup is finished in startup with batteries after, whether to carry out charge maintenance to batteries, be after earlier batteries being detected (measure proportion, measure the open circuit voltage of storage battery etc.) by operating personnel at present, according to the state of batteries, start charging device batteries is carried out boost charge again.Because the charging voltage of charging device is certain, the position difference of batteries, charging effect is different.Charging wire is short out, and line loss is little, the charging voltage height, and batteries is easy to generate and overcharges, and charging circuit length, line loss is big, and batteries causes easily owes charging.So directly have influence on the useful life of batteries.
As A, the B-battery group that stand-by power supply uses, A, B two group storage batteries hocketed and charge and discharge during it used.When a group storage battery was in discharge condition, another group storage battery was in stand-by state.Translation look-aside discharges with batteries, and the storage battery that has discharged need carry out boost charge.At present the standby battery group also be operating personnel rule of thumb with the result who measures, regularly or aperiodically it is charged.Because a variety of causes, operating personnel can not carry out charge maintenance to batteries in time, and it is longer to cause storage battery to be in time of power shortage state, and storage battery produces the lead sulfate precipitation, causes the pole plate sulphation, and capacity descends, and produces behindhand battery.Shortened the useful life of storage battery.
Aboard ship owing to narrow space, equipment is installed all very compact, and heat-dissipating space is very little, and storage battery is placed on the higher place of temperature for a long time, and various changing voltages must become with the temperature coefficient of battery tension in the charging process.The capacity of valve controlling type accumulator when ambient temperature is 25 ℃ is 100%; When surpassing 25 ℃, the capacity of 10 ℃ of storage batterys of every rising can reduce half; The charging voltage and the temperature of storage battery have much relations, 1 ℃ of the every rising of temperature, and the voltage of single lattice battery is with decline 3mV.That is to say that the voltage of lead-acid battery has negative temperature coefficient, its value is-3mV/ ℃.Hence one can see that, the very desirable charging voltage of work when ambient temperature is 25 ℃, and when ambient temperature dropped to 0 ℃, battery just can not full charge, and when ambient temperature is raised to 50 ℃, battery will shorten the life-span because of seriously overcharging.
Because the existing storage battery charge-discharge system is just finished batteries is charged and the conversion of standby battery group.Can not play batteries is effectively managed, the the administering and maintaining of batteries also needs to finish by operating personnel, so exist not enough: one, charging/discharging apparatus adopts centralized control, because equipment does not wait apart from the distance of batteries, line loss causes the inconsistent of charging voltage during charging, directly has influence on the charging quality to batteries; Two, because the mistake of apparatus settings is put a little lowlyer, can not in time charge to batteries after the conversion, it is longer that storage battery is in time of power shortage state and deep discharge state; Three, the user mode that equipment can not the dynamic tracking storage battery under artificial intervention, is difficult to guarantee the useful life of storage battery; Four, the volume of equipment and power consumption are excessive, and under the limited aboard ship power situation, too high loss meeting increases the weight of the burden of dynamical system, waste limited power resource.Five, storage battery is a kind of very complex apparatus, and is higher to temperature requirement, must carry out temperature-compensating to the charging of storage battery, guarantees in very wide temperature range, can both make just full charge of storage battery, do not owe to fill and overcharge and do not produce.

As shown in Figure 1, be the charging control flow chart of battery charge controller of the present invention, its process is:
1, when subsidiary engine started, batteries provided power supply to starter motor, and described manager detects the batteries terminal voltage in real time, once satisfy the charge condition that sets, started charging circuit immediately.

After described battery charge controller powers on, before the charge initiation, earlier the battery environment temperature is detected, and determine charging voltage value according to ambient temperature value; By voltage detecting circuit batteries is detected in real time, by the A/D change-over circuit signal that detects is become digital signal again, according to the voltage contrast of batteries terminal voltage that detects and manager stored, whether decision charges to batteries.In charging process, described manager detects the charging voltage of batteries and charging current in real time, and the contrast single-chip microcomputer parameter of depositing determines the control mode of whole charging process.
This battery charge controller can guarantee that storage battery electric weight in running is in the degree of depth of higher dump energy state, control battery discharging, because higher dump energy can effectively reduce the internal resistance of storage battery.Like this, when accumulator internal resistance is low, can reduce the temperature rise of storage battery in charging process, particularly under megathermal climate, not influence the useful life of storage battery its charging.The depth of discharge of control storage battery, higher at electric weight, the internal resistance of cell hour adopts little electric current that it is charged, and to prolonging the useful life of storage battery, prevents that early failure from being very useful.
