In this step, at first gather the single battery voltage of single battery when the described floating charge state of steps A in the lead-acid batteries; Secondly, the single battery voltage of single battery when the described band of step B puts electricity condition in the collection lead-acid batteries; The 3rd, the change in voltage scope of the single battery in the lead-acid batteries that first two steps are gathered is analyzed, and judges the size of its excursion and regulation boundary value; The 4th, if the change in voltage scope of described single battery during greater than the regulation boundary value, is carried out early warning to this single battery.
With reference to shown in Figure 2, lead-acid batteries generally is in three kinds of operating states, namely floating charge state, all fill state and discharge condition.In electric power DC system, the lead-acid batteries most of the time is under the floating charge state, under this state, system uses the dispatch from the factory single battery float charge voltage of regulation of lead acid accumulator to multiply by the battery joint number and obtain the lead-acid batteries float charge voltage whole Battery pack is carried out constant voltage charge.The lead acid battery charge process is the process of brine electrolysis, and chemical equation is as follows: 2PbSO
4+ 2H
2O=PbO
2+ Pb+2H
2SO
4, therefore, long-time charging process increases the acid concentration in the lead-acid batteries, and corrosivity strengthens, thereby reduces the life-span of lead-acid batteries.For this reason, when lead-acid batteries is in floating charge state, the voltage-regulation unit can regularly accurately be turned down the voltage on the charger automatically, certainly, also can regulate with manual mode, lead-acid batteries is be put, thereby and keep a period of time lead-acid batteries is carried out the shallow discharge activation, after reaching certain discharge voltage, battery management control unit readjustment charger voltage makes lead-acid batteries enter charged state.This active control mode can prolong the life-span of lead-acid batteries effectively, thereby reduces enterprise's spending.
When lead-acid batteries was in floating charge state, the univoltage collecting unit can accurately be gathered the voltage of each single battery in the lead-acid batteries, and the data of collection are passed to the battery management control unit in order to preserve by communication bus.Turn down charger voltage regularly, make in the process of lead-acid batteries discharge, the univoltage collecting unit can accurately be gathered the voltage of each single battery in the lead-acid batteries equally, and the data of collection are passed to the battery management control unit in order to preserve by communication bus.The analysis and early warning unit is analyzed at the magnitude of voltage that lead-acid batteries is under above-mentioned two different conditions every joint single battery in the lead-acid batteries that receives, when the change in voltage of a certain single battery during greater than boundary value, can report to the police to this single battery in the analysis and early warning unit, illustrate that this single battery exists internal resistance increase or performance downside risk.In this way, the risk that can accurately prevent single battery to exist ensures the operation of direct current power system better.
Lead acid accumulator group system with a cover 2V108 joint 300Ah is example, the charger even charging voltage is: 2.35V*108=253.8V, bulk charge stream: 0.1C10=30A, charger float charge voltage: 2.25V*108=243V, the floating current upper limit is defined as 1mA/Ah*300Ah=300mA, and regularly discharge cycle is decided to be 168h, is defined as 4h discharge time, the battery power discharge lower voltage limit is set to 220V, and single battery discharge voltage lower limit is set to 2V.Battery drop-off voltage alarming value is 0.15V.
Lead acid accumulator management system control charger carries out floating charge with the battery pack of float charge voltage 243V, by gathering floating current, charger voltage is finely tuned, and guarantees that floating current is less than 300mA.The control charger, when 168 hours discharge cycles arrive, then reduce charger voltage to discharge lower voltage limit 220V, drop to 2V and then stop discharge immediately when discharge time to 4 hour or battery voltage drop to 220V or arbitrary batteries voltage, record batteries voltage during this time, and carry out voltage and fall value relatively, to greater than 0.15V moment drop-off voltage battery report to the police.Enter after the discharge and all fill program automatically, with 253.8V voltage, the 30A electric current all fills battery.Enter floating charge state again after all filling end.
The above is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection range of the present utility model.
