动力型蓄电池也称牵引型叉车蓄电池，其工作原理与启动型蓄电池基本相同，在结构上，动力型蓄电池正极板一般采用管式极板，负极板是涂膏式极板。管式正极板是由一排竖直的铝锑合金芯子、外套以玻璃纤维编结成的管子；管芯是在铅锑合金制成的栅架格上，并由填充的活性物质构成。

叉车蓄电池依靠储能作为动力 电源，在充电、放电的版块有一套电路设计，一旦电路产生故障，那么电瓶叉车的电流输出将会增加，使用的时间自然缩短，充电也一样，设计不合理，充电不进或 者过大电流输入也一样，升压放电电路采用双闭环控制方式，以控制器输出电压作为反馈信号进行闭环控制。给定输出电压vref与实际输出电压比较得到误差， 经过pi调节器得到电流环给定电流iref。
给定电流iref与实际控制器输出电流比较得到电流误差，经过 pi调节器送给pwm波控制器产生驱动波形。驱动波形经过隔离驱动控制igbt开通与关断，进行dc/dc升压变换，实时的改变占空比来调节控制器输出电 流进而控制输出电压达到目标电压；电动叉车蓄电池的充电系统设计为该电路中变压器可以利用旧设各功率足够的闲置品，用 于短时间对蓄电池补充充电，功率允许稍小于充电功率（24v或12v、10a），二次电压应为18～22v。由于其充电电流为脉冲电流，这样既可提高充电 效率，也可降低变压器的温升。

电路中vd1～vd4对交流电压整流，形成脉动直流电。适当调整ri来控制cz的充电电压l以达到改变vt1发射极电压的目 的。vt1基极电位随脉动电压而变化，当它低于发射极瞬间电压时，vt1导通。r4上的压降使vt2随之导通。并经r5、r6分压的电压保持导通状态使二 极管vd5触发单向晶问管v导通，充电脉冲流经蓄电池组。当脉动电流过零时v关断。

叉车蓄电池的放电保护一般在叉车电路上额定了放电电压，比如一组48v700ah的电瓶组，在工作天的时候，电压、电流、电解液浓度会下降，一旦过度放电，叉车电池会  硫化加速，活性物质脱落，储能特性下降，将无法工作，影响后续的使用时间及动力；电动叉车的控制器上一般都设有欠压保护功能，当电量表显示只有一格电时， 应该关闭电源，尽可能快的对蓄电池进行充电，以免其过度放电。
蓄电池放电至终止电压内阻较大，电解液浓度非常稀薄，特别是极板孔内及表面几乎处于中性，过 放电时内阻有发热倾向，体积膨胀，放电电流较大时，明显发热甚至出现发热变形，这时硫酸铅会结晶成较大颗粒，即形成不可逆硫酸盐化，将进一步增大内阻，充 电恢复能力将变差，甚至无法修复。叉车蓄电池定期进行一次完全放电有利于“活化”电池，可以略微提升电池容量。但方法要正确。 电动叉车蓄电池是一种牵引作 用力的电瓶组，用多个单体串联不同的电压使用，工作强度比其他使用领域要高很多，很多用户注意到，使用一段时间后，这种电池的单体出现不平衡的状态，有些 容量高，有些很低，一旦干水后，全部单体叉车电瓶比重密度偏差很远，对于这种现象我们做了以下分析：单个蓄电池的电压与容量有限,在很多场合下要组成串连 蓄电池组来使用。但蓄电池组的中的电池存在均衡性的问题。
如何提高蓄电池组的使用寿命,提高系统的稳定性和减少成本,是摆在我们面前的重要问题。蓄电池的使用寿命是由多方面的因素所决定,其中重要的是蓄电池本身的物理性能。此外,电池管理技术的低下和不合理的充放电制度也是造成电池寿命缩短的重要原因。

对蓄电池组来说,除去上述原因,单体电池间的不一致性也是个重要因素。针对蓄电池充放电过程中存在的单体电池不均衡的现象,笔者分析比较了目前的几种均充 方法,结合实际捉出了无损均充方法,并进行了试验验证。 神钢叉车蓄电池在经长时间使用后，其保养的要求都有所改变。这意味着须较长时间充电或在充电的末期须更高的电流。通常越旧的蓄电池组需要更经常地加注蒸馏水，并且，蓄电池容量也相应地减退。神钢叉车蓄电池在使用前应该充足充电；以避免蓄电池在叉车运行过程中作间断性多次充电，这样会缩短其寿命及降低其容量。shinko is japan's kobelco forklift battery forklift battery, with1500 deep  circulation design life, sustainable work more than6 hours, at present  mainly shell lens licensing batteries,the normal use of more than 4  years, kobelco shinko forkliftbattery according to the iron box size,  capacity tocustomize, price related capacity, at present guangzhou bei langsi can supply japan gsyuasa, kobe kobe, hitachi hitachi,well-known:  xunqi, torch, day, camel, bockus such as theselection of voltage,  battery forklift, battery forklifttraction refers to as the driving  force, the battery is thecore of the forklift, crane, loading with  push, less batterygroup. such as forklift like scrap, no value, then  theforklift battery is how it formed? the power supply used in the battery forklift truck and the battery tractor is basically apower  battery. traction type batteries or forklift battery,its working  principle and starting battery is basically thesame in structure, the  positive plate batteries generally usetubular plate, the negative plate  is pasted plate. tubularpositive plate is formed by aluminum pipe  core, a verticalrow of antimony alloy coat with glass fiber; the tube  core isthe grid lattice made of lead antimony alloy, and is composed of active material filling. rely on forklift battery storage asa power  supply, a circuit design in the charging anddischarging section, once  the circuit malfunction, so thecurrent output will increase the use of  battery forklift,shorten the charging time of nature, too, unreasonable design, charging into or over current input, boost circuitthe double  loop control mode, the controller output voltageas a feedback signal  for the closed-loop control. the outputvoltage vref is compared with  the actual output voltage, andthe current loop is given iref through  the pi regulator.compared with the actual controller output current,  thecurrent error is given by a given current iref, and the pi controller is used to generate the driving waveform of thepwm  controller. the driving waveform after isolating drivecontrol igbt on  and off, dc/dc boost converter, real-timechange duty cycle to regulate  the output current of thecontroller and control the output voltage  reaches the targetvoltage; design of charging system of electric  forkliftbattery for transformer in the circuit can use the power of old enough idle goods, for a short time to charge the batterysupplement,  slightly less than the allowable power chargingpower (24v or 12v, 10a),  the two voltage should be 18 ~ 22v.because the charging current is  pulse current, the chargingefficiency can be improved, and the  temperature rise of thetransformer can be reduced. in the circuit, the  ac voltage isrectified by vd1 ~ vd4. proper adjustment of ri to control the charging voltage l of the cz to achieve the purpose ofchanging the  vt1 emitter voltage. the vt1 base potentialvaries with the pulse  voltage, when it is lower than theemitter instantaneous voltage, the  vt1 conduction. thevoltage drop on r4 causes vt2 to follow. and through  the r5,r6 voltage to maintain the state of the conductor to enable the diode vd5 to trigger a unidirectional transistor vconduction, charging  pulse through the battery pack. v turnoff when pulsating current is  zero.
discharge protection forklift battery forklift in general circuitrated  voltage of the battery group such as a group of48v700ah, when the day's  work, voltage, current density andelectrolyte concentration will  decrease, once the excessivedischarge, forklift battery will accelerate  thevulcanization, active material shedding, energy storage properties decreased, will not work, affect the use of the follow-uptime and  power; controller of electric forklift trucks aregenerally e  with undervoltage protection function,when only one electric power  meter display, should turn offthe power, as soon as possible to charge  the battery, so asto avoid the excessive discharge. battery discharge termination voltage to the larger resistance, theconcentration of the  electrolyte is very thin, especially theplate hole and the surface is  almost neutral, overdischargeresistance heating tendency, volume  expansion, dischargecurrent is high, obvious fever and even fever  deformation,then will lead sulfate crystallization into larger  particles,namely the formation of irreversible sulfation, will to further increase the internal resistance, charge recoveryability will  become worse, even unable to repair. forkliftbatteries on a regular  basis for a full discharge isconducive to "activate" the battery, the  battery capacity canbe slightly improved. but the method is right.  electricforklift battery is a battery group traction force, with a single series of different voltage, the intensity of work ismuch higher  than other areas of use, many users noted thatafter a period of time,  monomer unbalanced in the cell, somehigh capacity, some very low, once  dry water, all of themonomer battery forklift proportion density  deviation veryfar, for this phenomenon, we made the following analysis: single battery voltage and capacity is limited, on manyoccasions to  form a series of battery to use. but the batteryin the battery pack has  the problem of e how toimprove the service life of the  battery, improve thestability of the system and reduce costs, is an  importantissue in front of us. battery life is determined by many factors, of which the most important is the physicalproperties of the  battery itself. in addition, the lowbattery management technology and  unreasonable charging anddischarging system is also an important reason  for shorteningbattery life. in addition to the above reasons, it is  also animportant factor for the battery pack. according to the single battery battery charge and discharge process of theunbalanced  phenomenon, the author analyzed the currentcharging method, combined  with the actual catch anondestructive and the charging method.
