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,在工作一天的时候,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, with 1500 deep circulation design life, sustainable work more than 6 hours, at present mainly shell lens licensing batteries, the normal use of more than 4 years, Kobelco SHINKO forklift battery according to the iron box size, capacity to customize, 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 the selection of voltage, battery forklift, battery forklift traction refers to as the driving force, the battery is the core of the forklift, crane, loading with push, less battery group. Such as forklift like scrap, no value, then the forklift battery is how it formed? The power supply used in the battery forklift truck and the battery tractor is basically a power battery. Traction type batteries or forklift battery, its working principle and starting battery is basically the same in structure, the positive plate batteries generally use tubular plate, the negative plate is pasted plate. Tubular positive plate is formed by aluminum pipe core, a vertical row of antimony alloy coat with glass fiber; the tube core is the grid lattice made of lead antimony alloy, and is composed of active material filling. Rely on forklift battery storage as a power supply, a circuit design in the charging and discharging section, once the circuit malfunction, so the current output will increase the use of battery forklift, shorten the charging time of nature, too, unreasonable design, charging into or over current input, boost circuit the double loop control mode, the controller output voltage as a feedback signal for the closed-loop control. The output voltage Vref is compared with the actual output voltage, and the current loop is given Iref through the PI regulator. Compared with the actual controller output current, the current error is given by a given current Iref, and the PI controller is used to generate the driving waveform of the PWM controller. The driving waveform after isolating drive control IGBT on and off, DC/DC boost converter, real-time change duty cycle to regulate the output current of the controller and control the output voltage reaches the target voltage; design of charging system of electric forklift battery for transformer in the circuit can use the power of old enough idle goods, for a short time to charge the battery supplement, slightly less than the allowable power charging power (24V or 12V, 10A), the two voltage should be 18 ~ 22V. Because the charging current is pulse current, the charging efficiency can be improved, and the temperature rise of the transformer can be reduced. In the circuit, the AC voltage is rectified by VD1 ~ VD4. Proper adjustment of RI to control the charging voltage l of the CZ to achieve the purpose of changing the VT1 emitter voltage. The VT1 base potential varies with the pulse voltage, when it is lower than the emitter instantaneous voltage, the VT1 conduction. The voltage 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 V conduction, charging pulse through the battery pack. V turn off when pulsating current is zero.
Discharge protection forklift battery forklift in general circuit rated voltage of the battery group such as a group of 48V700AH, when the day's work, voltage, current density and electrolyte concentration will decrease, once the excessive discharge, forklift battery will accelerate the vulcanization, active material shedding, energy storage properties decreased, will not work, affect the use of the follow-up time and power; controller of electric forklift trucks are generally equipped with undervoltage protection function, when only one electric power meter display, should turn off the power, as soon as possible to charge the battery, so as to avoid the excessive discharge. Battery discharge termination voltage to the larger resistance, the concentration of the electrolyte is very thin, especially the plate hole and the surface is almost neutral, overdischarge resistance heating tendency, volume expansion, discharge current 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 recovery ability will become worse, even unable to repair. Forklift batteries on a regular basis for a full discharge is conducive to "activate" the battery, the battery capacity can be slightly improved. But the method is right. Electric forklift battery is a battery group traction force, with a single series of different voltage, the intensity of work is much higher than other areas of use, many users noted that after a period of time, monomer unbalanced in the cell, some high capacity, some very low, once dry water, all of the monomer battery forklift proportion density deviation very far, for this phenomenon, we made the following analysis: single battery voltage and capacity is limited, on many occasions to form a series of battery to use. But the battery in the battery pack has the problem of equalization. How to improve the service life of the battery, improve the stability of the system and reduce costs, is an important issue in front of us. Battery life is determined by many factors, of which the most important is the physical properties of the battery itself. In addition, the low battery management technology and unreasonable charging and discharging system is also an important reason for shortening battery life. In addition to the above reasons, it is also an important factor for the battery pack. According to the single battery battery charge and discharge process of the unbalanced phenomenon, the author analyzed the current charging method, combined with the actual catch a nondestructive and the charging method.
