电动叉车的电池容量迅速下降的原因是什么?

来源:/ 日期:2020-12-31 发布人:hangong

随着每个研发部门都在积极开发节能环保产品。在工业市场上,工业设备车辆凭借操作简便,维护简单,安静,无污染等特点迅速占领了一定的市场。电动叉车是室内工作的理想选择。当前市场上的大多数电动叉车都使用设计成便宜的电池。一些用户问小编,叉车电池容量下降的原因是什么?

As each R & D department is actively developing energy-saving and environmental protection products. In the industrial market, industrial equipment vehicles with simple operation, simple maintenance, quiet, pollution-free features quickly occupied a certain market. Electric forklift is an ideal choice for indoor work. Most electric forklifts on the market today use batteries designed to be cheap. Some users asked Xiaobian, what is the reason for the decline of forklift battery capacity?
1.叉车电池到达用户后,可以及时安装和使用,可以长期存放。长期存放将不可避免地引起自放电,从而导致容量不足。由于电池的长时间存放不正确,因此必须每隔一次对电池充电一次。
1. After the forklift battery reaches the user, it can be installed and used in time and stored for a long time. Long term storage will inevitably lead to self discharge, resulting in insufficient capacity. Because the battery is not stored correctly for a long time, it must be charged every other time.
2.叉车电池的正极板被腐蚀,变形导致容量不足。
2. The positive plate of forklift battery is corroded and deformed, resulting in insufficient capacity.
叉车电池的正极板是影响电池使用寿命的主要因素。叉车电池充放电循环的容量,特别是深循环的容量减少与正极板的质量偏差密切相关。
The positive plate of forklift battery is the main factor affecting the service life of the battery. The capacity reduction of forklift battery charge discharge cycle, especially the capacity reduction of deep cycle, is closely related to the quality deviation of positive plate.
2.1活性物质软化并掉落在正极网格上
2.1 the active material softens and falls on the positive grid
微观活性材料中有大孔和微孔。大孔径超过0.5cm。它由许多小孔组成。随着放电周期的进行,活性表面会收缩并形成一个珊瑚状结构的核心。在二次放电循环中,小孔的积累增加,使得大孔连续增加,正极结构被破坏,并且活性物质脱离。
There are macropores and micropores in micro active materials. The large pore size is more than 0.5cm. It consists of many small holes. As the discharge cycle goes on, the active surface shrinks and forms a coral like core. In the secondary discharge cycle, the accumulation of small holes increases, resulting in the continuous increase of large holes, the destruction of the positive structure and the separation of active materials.
这些情况的主要原因是叉车电池的大电流充电和放电。避免发生应保证充电和放电的电流,并避免过度充电或过度放电。
The main reason for these situations is the high current charging and discharging of forklift battery. Avoid the occurrence of current that should ensure charging and discharging, and avoid overcharging or excessive discharging.

2.2正网格腐蚀变形
2.2 positive grid corrosion deformation
栅板的腐蚀速率取决于栅板合金的成分,但是储存温度越高,腐蚀速率越快,放电深度越深,腐蚀越严重。
The corrosion rate of grid depends on the composition of grid alloy, but the higher the storage temperature is, the faster the corrosion rate is, and the deeper the discharge depth is, the more serious the corrosion is.
3,电动叉车蓄电池负极板硫酸化:
3. Sulfation of negative plate of electric forklift battery:
在正常操作中,负极板上的PbSO4颗粒很小,放电容易恢复为蓬松的铅,但是有时电池内部会产生难以还原的硫酸铅,这称为硫酸化。
In normal operation, PbSO4 particles on the negative plate are very small, and it is easy to recover to fluffy lead during discharge. However, sometimes lead sulfate, which is difficult to reduce, is produced in the battery, which is called sulfation.
使负盐盐化的原因有很多。例如,放电后不能及时充电。电池长时间放置会导致严重的自放电。电解质浓度过高,长期充电不足,长期放电高。该硫酸铅难以通过常规方法还原。因此,活性物质的减少将不可避免地影响叉车电池的容量。
There are many reasons for the salinization of negative salt. For example, it can not be charged in time after discharge. Long time storage of battery will lead to serious self discharge. The electrolyte concentration is too high, the long-term charge is insufficient, and the long-term discharge is high. The lead sulfate is difficult to be reduced by conventional methods. Therefore, the reduction of active substances will inevitably affect the capacity of forklift battery.
电动叉车和小叉车提醒大家,在购买叉车电池时,要注意假冒或二手物品,因为一些制造商为了提高整体竞争力,降低产品质量降低价格以赚取利润,所以寻找大品牌的正确选择。
Electric forklifts and small forklifts remind you that when you buy forklift batteries, you should pay attention to counterfeit or second-hand goods, because some manufacturers are looking for the right choice of big brands in order to improve their overall competitiveness, reduce product quality and price to earn profits.
