Battery you must know the knowledge!

? Q: Why is the high battery best use a lying, the low battery is best placed? A: High battery vertical density causes the internal electrolyte layers in the battery, after the time is taken, the density of the upper layer is thinner, and the lower sulfuric acid density is concentrated, thereby forming a concentration microcontroller, so that the battery is severe, shortened Battery life. The low battery electrolyte layers is much smaller, while the use of vertical isas will effectively reduce the possibility of battery leakage, so the short battery should choose to stand up. ? Q: How to determine the battery installation? A: For valve-controlled batteries that use AGM technology, highly designed batteries should select horizontal lying in installation to avoid generating electrolyte layers during use. When installing, mainly consider the installation area and ground load weight, the user can choose the two-layer, four-layer and octave installation method according to the battery placement area, and if the ground load is allowed, the four layers or eight-layer mode can be saved. The area is suitable for the battery to be placed on the first floor or the basement, which is preferably installed in a case where there is a poor load capacity of sufficient area. Specific installation“Battery installation manual”. Exceed“Installation Manual”Outside, technical personnel are specially designed for customers, also known as special designs. ? Q: Why is new and old batteries, different types of batteries, it is best not to mix? A: Due to the new and old battery, the battery internal resistance of different types of batteries is different, the battery is distinguished during charge and discharge, such as tandem use will cause a single charge or incarnate; if in parallel, it will cause charge and discharge and discharge bias, each The current of the group battery is inconsistent. ? Q: What projects do you need to check often during the operation and maintenance process? Answer: (1) The total voltage of the battery, charging current, and the floating voltage of each battery; (2) There is no loosening, corrosion of the battery connection; (3) There is no leakage and deformation of the battery housing; (4) The pole column of the battery is surrounded around the safety valve. ? Q: What is a floating voltage? How to determine the floating voltage of the battery? A: When the floating charge is used, the battery's charging voltage must remain a constant value. At this voltage, the charge and discharge amount should be sufficient to compensate for the battery loss loss due to self-discharge, and ensure that the need for oxygen circulation is guaranteed to make it in a relatively short period of time. The electrically conductive battery is fully electrically, which can make the battery last in a sufficient electrical state, and the selection of the voltage should cause the battery to minimize the minimum due to overcharge, which is called a floating voltage. ? Q: The newly installed battery, some pressure differences, will it affect the use? A: After a certain amount of time floating, the floating voltage will tend to be uniform, because the use of sulfuric acid saturation is high, the gas composite efficiency is poor, the saturation of the gas is reduced, the battery floating voltage is also Will uniform. ? Q: What are the causes of battery voltages during long-term floating speed? A: At present, the VRLA battery has uneven floating voltage, which is caused by the quality, quantity of the material used in each of the production of batteries, and the amount of error accumulation, especially the VRLA battery, is used. The error will affect the sulfate saturation inside the battery, which directly affects the complexation of oxygen when the battery is floating, so that the over-potential of the battery is different, and the floating voltage of the battery is different. However, the floating voltage will tend to be uniform after the VRLA battery is running for a certain period of time. Because the amount of battery oxygen-saturated battery is poor, the saturation is slightly lowered, and the floating voltage of the battery tends to be uniform. Another battery is connected in series; poor pillar and connection strip are poor contact; there may be uneven phenomena in the operation of 3 to 6 months. ? Q: How does the battery floats when the battery is running? A: Backward battery is low in the end voltage, so the backward battery should be measured in the discharge state. If the end voltage is measured in a continuous three-discharge cycle, it can be sentenced to the backward battery in the group, there is a backward battery. The battery pack is balanced. For example, for batteries in a floating state, if the floating voltage is below 2.16V, it should be attached. ? Q: Is the battery sometimes burden, will it affect the battery? A: Due to the internal pressure of the battery, the battery housing has a slightly housing blotlation, one aspect of the manufacturer should pay attention to the opening of the safety valve, so that the internal pressure of the battery is not too large, and selects the appropriate housing material, shell The body thickness; on the other hand, the user should perform normal maintenance of the battery to avoid overcharge and thermal out of control. ? Q: How much time does it take to charge when the battery is discharged? A: The time required for the battery sufficient power after the discharge changes with the release capacity and the initial charging current. If the battery is discharged from 10H, the battery is 100% battery, the battery passes“Constant voltage limit”and“Constant current limiting”After 24 hours of charging, the charge can reach more than 100%. ? Q: Which types of battery leaks are all, mainly those phenomena? A: The key to the valve sealing battery is sealed, such as the battery leak, can not live in a living room with the communication machine room, must be replaced. Phenomenon: a. There is a white crystal around the pole, which is clearly black corrosion, and there is sulfuric acid droplets. b As the battery is inserted, the ground has a white powder corroded white powder. The C-pole column copper core is green, the liquid droplets in the spiral sleeve are obvious; or the droplets in the groove cover are obvious. Reason: a. Some battery screw loops, sealing rings are reduced to cause fluid. B Sealing Glue Aging results in a sealing. c. The battery is seriously overcharged, different types of battery mixed, battery gas composite efficiency. d. Splash of the acid liquid in an acid, resulting in a fake leakage. Measures: a. For the possibility that it is a pseudo-leakage battery, it will be observed later. b. Strengthen the screw jacket of the leakage battery and continue to observe. C. Improve the battery sealing structure. ? Q: Why is the battery in use?“Can't put electricity”? A: The battery is discharged in a normal floating state, the discharge time does not reach the requirements, the program-controlled switch or the battery voltage on the electric device has dropped to its set value, and the discharge is in the termination state. The reason is; The battery discharge current is exceeded rated current, causing insufficient discharge time, while the actual capacity is reached; When the floating charge, the actual floating voltage is lacking, which causes the battery for a long time, the battery capacity is insufficient, and may result in battery sulfate. The battery connection bar is loose, the contact resistance is large, causing the discharge, and the connecting strip is large, and the battery voltage drop is faster (the charging process is reversed, the battery voltage rises faster). The ambient temperature is too low during discharge. As the temperature is lowered, the battery discharge capacity also decreases. ? Q: Can the battery are hot and temperature affect the battery? A: General situation, in the charge and discharge process, due to the large current, there is a certain internal resistance, the battery will produce a part of the heat, and the temperature is elevated. However, when the charging current is too large, the interga gap is too small to cause a cumulative enhancement of the charging current and battery temperature, and damage the battery, causing thermal out of control. In particular, the charging device used by the user is an AC power supply, which is filled with filtered, but still has a corrugated voltage. And a fully charged battery is small, even if the voltage change is small in the battery line, the temperature of the battery is increased, and the temperature of the battery is increased, and the temperature is increased, and the strength of the battery shell is decreased. Causes the bulging of the battery and causes the battery damage. ? Q: Can the battery capacity can be measured by electrical conductivity, what is the current situation at home and abroad? A: Dr. D.Feder, American scientist believes that the greater the battery's conductance value, the higher the capacity, and there is a linear relationship between battery conductors and battery capacity. The battery conductive measurement method has been studied in China. Its conductive test data indicates that the conductivity test method is effective in evaluating the capacity of the VRLA battery, but in other cases, battery conductors and battery capacity Linear relationships do not exist. In the following case, there is a linear relationship between VRLA battery conductors and other indicators: A. For the same series of batteries, nominal capacity ~ average conductance; B. For a single battery cell, battery capacity ~ battery conductance; C. During the discharge process, battery capacity ~ battery conductors; D. Battery temperature ~ battery conductors. VRLA battery internal resistance range is from 10 to 3 to 10-5 ohms, and many factors can affect the accuracy of battery conductivity measurement. Such as the battery connecting strip or the oxide layer of the pole surface, the contact resistance between the connecting strips and the terminal, and the like. Since the VRLA battery is a poverty design, the internal gas of the battery has a great impact on the measurement of the battery conductance. In short, it is very difficult to establish a standard electrical guide value for a model battery. In fact, the main battery manufacturers do not agree to test the capacity of the battery in conductive indicators.
