Correct check battery balance of heavy truck in traction battery in the process of charging, hydrogen, should stay away from open flame, do not smoke in nearby, forklift as necessary logistics equipment, most of the time didn’t get the standard management, use and in order to further check the fault nature and degree of battery, so that the technical state of exact judgement, Can be combined with the battery charging process inspection, according to the different performance of the battery charging inspection, identify the internal failure of the battery and its causes.
Battery water supplement two misunderstandings do an analysis: misunderstanding one: often drinking pure water can be used for battery use? Can not be used, because the daily drinking pure water impurities content is far higher than the battery water requirements, pure water contains a variety of trace elements, will cause adverse effects on the battery. Battery water should reach JB/ T10053-1999 standard requirements, this pure water is not up to. Therefore, we should remember in the loss of electrolyte should be added distilled water or special rehydration, do not use drinking water instead of pure water.
Myth two: Can you add distilled water at any time? In the battery routine maintenance, when the electrolyte is insufficient, generally distilled water should be added. But sometimes the electrolyte is reduced because of the battery shell damage crack or liquid hole cover buckle lax electrolyte leakage caused. And some drivers often do not pay attention to distinguish when checking the liquid level height is due to battery shell damage or other reasons caused by electrolyte leakage, or normal loss, as long as the electrolyte level is reduced by adding distilled water, resulting in significantly lower electrolyte density, so that the battery can not work normally.
Some drivers often add distilled water after the car, the result of the added distilled water can not be fully mixed with the battery original electrolyte, so it is easy to make the battery self-discharge or damage the battery plate, in cold areas will also cause the battery local icing phenomenon, affecting the service life of the battery. On the contrary, if you add distilled water to the battery before the car, the distilled water can be fully mixed with the original electrolyte in the battery, the battery performance will not be affected. Therefore, distilled water should be added before the car, and not after the car. When the battery is charged, the electrolyte is cloudy, the battery capacity is reduced, the charging time is shorter than the normal battery, and the phenomenon of electrolyte boiling at the end of the charge will appear in advance. Self-discharge battery, charging time is longer, electrolyte proportion and terminal voltage rise slowly.
In general, the electrolyte in the battery will evaporate during charging and use, so the concentration will increase. Generally, water is added, and the electrolyte of 1.26 specific gravity is added at the bottom of the specific gravity. The specific gravity after charge is 1.28. Pay attention to these, forklift batteries will be used for longer, the endurance can also be maintained. If there is a serious short circuit in the battery, no matter how long the charging time, the electrolyte proportion and the end voltage will not rise, the battery more no bubbles, the electrolyte is like a pool of stagnant water.
