Generally positive plates, negative plates, separators, tank batteries, the electrolyte and terminals components. What time of the lead-acid batteries who invented? 1859 Plant invention. Lead-acid batteries in the battery family occupies what proportion? Lead-acid batteries account for a large proportion of the entire battery, according to statistics about 65%. 6. Domestic lead-acid battery manufacturers? The website contains a total of more than 2,500 (excluding research universities and other research institutions), the country engaged in lead-acid battery production, lead-acid battery plant more than 2,000, more than 500 raw materials, components, equipment. 7 used lead-acid batteries are the types? Use can be divided into: start-up battery, fixed, traction power type. 8 What is the capacity of lead-acid batteries, how to calculate? Under specified conditions, a fully charged battery can provide power, usually ampere-hours (Ah). Capacity = single admonish plate number of single plate capacity. The main component of the lead-acid battery electrolyte is it? Is a mixture of sulfuric acid and distilled water (or deionized water). 10 lead-acid battery electrolyte What is the harm to the human body? Lead-acid battery electrolyte is a strong acid on human skin, eyes were damaged, once you have made contact should wash immediately with plenty of water, serious should be promptly to the hospital for treatment. 11 lead in lead-acid batteries What is the harm to the human body? Lead oxide and lead in lead-acid batteries have a certain impact on the human nervous system, digestive system, blood system and kidneys, usually best not to waste battery anatomy. Please note that the protection and guidance staff time required to dissect. 12 absorption of lead poisoning What is the treatment? Absorption of lead poisoning after entering professional treatment institutions treatment, engaged to lead operations in the diet can be more drinking milk, soy milk is conducive to the lead out of the body. 13. Those kinds of common battery slot? The common battery slot hard rubber and polypropylene, cars, motorcycles, traction battery slot, the ABS made sealed battery compartment, and a small amount of polystyrene battery compartment. 14 common battery separators are those? The common battery separator rubber diaphragm, PP separators, PE partitions, PVC partitions and AGM separator. 15 daily drinking pure water can be used for battery use? Can not be applied because The daily drink pure water impurities is much higher than the battery's water requirements, just some of the elements of water, sediment bacteria less beneficial to humans. Battery water should to reach JB/T10053-1999 standard requirements. 16 lead-acid battery manufacturing commonly used alloys are those? The alloy used in the manufacture of lead-acid batteries with lead-antimony alloy, lead low-antimony alloy, lead antimony, cadmium alloy and lead calcium alloy. 17 lead-acid battery charging methods are those? Constant current charging, constant voltage charging, constant current limit voltage charging, equalizing charge, floating charge and fast charging pulse. 18 lead-acid battery, the electrolyte density, open circuit voltage relationship? Open-circuit voltage = 0.85 + electrolyte density (empirical formula) 19. Capacity of lead-acid battery plates depends on what? Depends primarily on the positive and negative plates amount of active substance. 20 What is the main component of the lead-acid battery positive and negative plates? The main component of the positive electrode plate active material is lead dioxide, the main component of the negative plate active material is sponge lead. 21 lead-acid battery electrolyte density and the percentage of how do you convert? Density 1.25g / cm 3 sulfuric acid electrolyte weight percentage at 25 ℃ approximately 33.5% density 1.28g / cm 3 sulfuric acid electrolyte weight percentage of about 37.3%, density 1.30g / cm 3 sulfuric acid electrolyte weight percentage approximately 39.5% of the sulfuric acid electrolyte density 1.40g / cm 3 weight percent of about 50.5%. 22 lead-acid battery charging, why fever? Battery during the charging process portion of the transition, energy to chemical energy, also with partially converted into heat and other energy. Rechargeable battery fever is a normal phenomenon, but high temperatures should be checked in time whether the charge current is too large or battery internal short circuit, calorific value and the amount of electrolyte between smaller case sealed battery electrolyte less internal resistance increase also cause the battery raw temperature and charging high voltage. 23 lead-acid battery charging, why have a pungent odor? Battery during charging, the battery internally generated sulfuric acid vapor, water vapor, hydrogen and oxygen mixture of substances escape spread to the air, it will give the impression Road pungent odor. 24 What is the lead-acid battery float charging, equalizing charge? Floating charge: battery power to the circuit when the normal power supply is interrupted. The terminal is always connected to the constant voltage power supply, in order to maintain the battery is nearly fully charged state. The equalizing charge: To ensure the continuation of all single battery in the battery pack is fully charged a charge. 25 new lead-acid battery added to the electrolyte, the temperature rise is why? The new battery is added to the electrolyte, the temperature rise with a new battery and internal factors. Dry charged battery fluid temperature rise, the battery temperature is not very obvious, which is dry charged plates after anti-oxidation treatment, the factory battery so in a fully charged state, after adding liquid to load use; ordinary plates battery without antioxidant treatment, negative plates in a half fully charged state, a considerable portion of the material in the reaction generates a lot of heat for the lead oxide and dilute sulfuric acid, so long high temperature. Sometimes the summer temperature of 50 ℃, the charge should pay attention to artificial cooling. 26. Constant current limiting of VRLA battery charge, and how to determine if the battery is fully charged? There are two basis: 1) charging time of 18 to 24 hours (deep discharge can be short, such as 20% depth of discharge of the battery, the charging time can be shortened to 10 hours). 2) The charge current is reduced to the minimum value and remain unchanged for three consecutive hours. 27. Produce plate sulfation.? The to produce plates sulfated reason the following points: 1) the initial charging of the battery is insufficient or initial charge interruption longer; 2) Battery charge long enough; 3) failure to charge after discharge; 4) often overcharge or current deep discharge; 5) the electrolyte density too high or the temperature is too high, the lead sulfate depth form is not easy to restore; 6) Battery shelved a long time, long-term use without periodic charging; 7) electrolyte impurities, self-discharge large; 8 ) local effects of internal short circuit or battery surface water caused more leakage; 9) inside the battery electrolyte level is low, and the plate exposed part of sulfated. 28 battery storage requirements? Good ventilation, dry (preferably mounted air conditioning), to maintain the ambient temperature around 25 ℃; stronger ground bearing capacity; store three months to conduct additional power. 29 What are the causes and how to solve battery leakage? The reasons: a) sealant caused by the aging sealing cracks; b) severe overcharge mix different types of batteries, battery gas recombination efficiency; c) acid-filling when the acid spilled, resulting in false leakage. Solution: 1) may be false wipe the battery leakage, left latter observation; 2) replacement of leaking batteries. 30. The capacity detection capacity battery pack should be how to deal with? 1) to deal with the entire group battery charging process, that are full 18-24 hours.
