How is the battery lack of electricity after long-term deposit repaired?

Accumulator batteries battery electric charge cannot get how to do?

　　We first check if the battery is missing electrolyte. (Of course, you can check if there is a short circuit.) If the electrolyte is dry, add distilled water first. After adding enough, do not cover the battery. Then proceed to the next step, "Activate" - find a 220V/200W ordinary incandescent lamp and battery in series (without positive and negative polarity) to the home 220V AC power supply to see if the light bulb can normally shine, if it can be normal The light will continue to be energized for about 1 minute and then disconnected from the power supply. Wait a few minutes for another minute, then repeat the 3~5 times and then connect the battery to the charger for 15 hours of normal charging. If you still can't, then you can consider renewing it.

　　Several battery repair methods commonly used in battery repair

　　Battery repair: common battery repair methods

　　Several common battery repair methods battery repair is not difficult. For example, it is difficult to repair the entire battery (series) at the same time (except for battery vulcanization). As long as one battery in the battery pack is physically damaged, the effect of using the repairing instrument is not obvious, but the battery pack should be separated. The battery is repaired separately, not only can detect the type of battery damage, but also can be repaired by different methods. Therefore, the key to repairing the battery is to repair the single battery (usually 12V), Jiajun Electric Vehicle Co., Ltd. Here are a few ways: 1 pulse repair method:

　　A better way to eliminate vulcanization in batteries is to use pulse repair. When repairing the battery, the instantaneous voltage of the pulse is generally based on the functional requirements embodied in the product. The instantaneous voltage is 60V-300V. For example, the pulse voltage value of the product used for battery life extension is not too large, especially for battery repair products. The pulse voltage value can be too large (if the pulse voltage value is too large, it will cause damage to the battery plate), the pulse voltage is high, the battery repair time is short, the pulse voltage is low, and the battery repair time is relatively long, although the pulse voltage is very high. High, but the average voltage is not high, no harm to the human body, very safe. Physically, any insulating layer can be broken down at a sufficiently high voltage. Once the insulating layer is broken down, the coarse lead sulfate will be in a conductive state. If a high voltage is applied to the high-resistivity insulation, large lead sulfate crystals can also be broken. If this high voltage is short enough and current is limited, the charging current is not large under the condition of breaking through the insulating layer, and a large amount of gassing is not formed. The strong gassing volume of the battery is positively related to the charging current and the charging time. If the pulse width is short enough and the duty ratio is large enough, under the condition of ensuring the breakdown of the coarse sulphate crystal, the simultaneous micro-charging cannot form the gassing. This achieves pulse elimination vulcanization. There are special pulse generators on the market, but pay attention to the selection of a good effect. The resonance between the pulse and the battery plate is very important, which depends on the pulse frequency and the width and width. If the pulse frequency and amplitude are not enough, the effect of eliminating the crystallization of sulfuric acid will not be achieved. If the frequency and amplitude are too large, the vulcanization will be eliminated and the damage will be eliminated. The electrode plate has a gassing phenomenon; at the same time, there are many kinds of pulse waveforms, which can be displayed on the oscilloscope. A good pulse wave can effectively break down the insulating layer under the premise of the non-destructive battery, and the pulverized sulfuric acid crystal powder is reduced in the electrolyte. This is like a broken stone, facing a large stone, is it effective with artichokes, or is it effective with hoes? I can see it at a glance. 2, strong electric repair method:

　　The strong electric repair method is a method of repairing the battery by using a persistent high voltage or a large current during charging, and is often used when the effect of the pulse repair method is not obvious. First, the high voltage repair method: This method mainly uses the charging voltage of 1.3-1.5 times of the nominal voltage of the battery to repair the battery. For example, the 36V battery is charged by the 48V charger under the condition that the charging current is constant or close. The charging time should be mastered, it is not easy to be too long, otherwise the battery will be heated due to gassing. This method has a certain repairing effect on a battery with short circuit and low softening of the electrode plate, but improper use may also cause damage to the pressure plate of the battery plate. Second, the high current repair method: This method is mainly to use a charging current 1.5-2.0 times higher than the usual charging current to repair the battery, such as 20AH battery using 3-4A charger for charging, pros and cons and "high voltage repair The law is the same. 3, full charge full discharge repair method:

　　The full charge full discharge repair method is a method of repairing the battery after the battery is fully charged and then completely discharged. The full charge and full discharge repair method mainly has a certain repairing effect on the battery with mild damage, and the method can also effectively activate the active substance in the deep layer of the battery and improve the battery capacity. For example, a slightly vulcanized battery and a battery with a high internal resistance, the key to this method is that the discharge must be sufficient, and the individual cells are individually fully discharged, fully charged and discharged 1-2 times, and the capacity of the battery. Generally it can be improved. Fully charged discharge repair method must not be used frequently, at least once every six months, most

　　Use every three months. 4, hydration repair method:

　　The method of replenishing water for the "water loss" of the battery can be repaired, and the purpose is to normalize the electrolysis reaction by diluting the sulfuric acid with increased concentration. The method of hydrating is relatively simple. Just open the upper cover of the battery, you can see that there are six round holes, and inject a certain amount of distilled water into each round hole, and then soak for more than 24 hours. The hydration can only be supplemented with distilled water. It is not allowed to add water of other ingredients, including pure water. Because other components have various metal molecules in the water, it is easy to cause self-discharge and damage the battery after being added into the battery.

　　5, re-matching repair method:

　　The electric vehicle battery is generally a battery pack made up of several batteries in series. The battery damage is multi-faceted. There may be several damages in the battery at the same time: for the vulcanized battery, the repair effect is better; but for the pole The softened and broken battery of the board can be repaired immediately. Because it is a physical hard wound, it can be reused little, and the use time after repair is also very short, and the effect of repairing will be even worse. The best way is to replace the old battery with the repair value (replace the old battery with more than 80% capacity), and then re-group with the remaining batteries. The battery has a long life and the battery is just repaired to maintain its normal design life. It is unscientific and unrealistic to promote battery repair products to repair battery damage caused by any factor, just like the new battery, and to ensure that the battery can extend its service life. Battery damage without any factors has an impact on battery life. The problem is how to reduce battery damage and how to reduce the impact on battery life. The following is a brief introduction to the daily maintenance methods of several electric vehicle batteries for users' reference.

　　Firstly, "every day with the car, charging every day." Lead-acid batteries have no memory, so the rapid reduction of capacity is mainly due to some reasons such as battery vulcanization and "water loss" and "debt loss". The battery is most afraid of "defective power" under voltage, battery often "depleted", battery pole The board is extremely vulnerable. We found that up to 70% of the battery capacity of the electric vehicle is reduced by the strong current (starting current) when the electrode plate is discharged (the electric motor is particularly obvious), and the electrode plate strain is a physical damage of the battery. This damage cannot be repaired. Therefore, "every day with the car, every day charging", to ensure that the battery has sufficient voltage at any time becomes inevitable.

　　Secondly, take regular addition of distilled water. Users generally believe that maintenance-free batteries do not need to add water, in fact, this statement is wrong. Maintenance-free batteries generate heat during charging and high-current discharge. If there is heat, water will evaporate. Although the process of water evaporation is very slow, the amount of accumulated water evaporation cannot be ignored for a long time. Therefore, the battery should be replenished once every 6 months or so, so that the service life of the battery will be prolonged. Third, the electric car starts with skill. The starting current of the electric vehicle is very large, especially the electric motor of the high-power motor, and the starting current is larger. The high current is very harmful to the battery plate. The best way is to start the electric car before riding, just like riding a bicycle. Of course, many electric motorcycles do not have a riding device, and there is no way.

　　4. Discharge the battery once a quarter. After the battery is used for a period of time, some active substances will inevitably sink. If the active substances are not activated in time, it will inevitably have some impact on the capacity of the battery. Therefore, when using the electric vehicle frequently, it is necessary to make the battery every season. Deeply discharge once.

　　5, often observe the quality of the charger. The charging process of the new battery is generally 6-8 hours. When the battery is fully charged, the charger will light green. If the charging time is too long, check whether the charger voltage protection device is damaged. If it is damaged, you need to change the charger in time. Otherwise it is easy to charge the battery. In addition, the charger should not buy a fast charger, and fast charging also has damage to the battery plate.

　　6. When charging the battery for a long time, charge the battery at least once a month. The purpose of this is to prevent the battery from being placed for too long and causing the battery to vulcanize and "deplete".

　　7, Prevent battery explosion. Explosive exposure will increase the temperature of the battery, so be careful.

　　8. Use the battery protector as soon as possible. The battery protector is also a pulse generator. The pulse is uninterrupted to eliminate the vulcanization of the battery, so that the plate is always kept "clean", thus achieving the effect of prolonging the service life of the battery, but it has little effect on the damage of the battery plate with high current (if any) The electric motor uses a charger with a pulse, and as a result, the life extension effect of the battery is not obvious.) New technologies must be added to improve it.

　　1. Connect the single battery in series to the required battery pack, then correctly connect the matching "Repairer", plug in the charger power supply, and continue to let the "Repair" be maintained and organized when the charger green light is on. The battery is more than 6 hours, and finally the charger is unplugged for discharge. For the first time, it should be deep discharge. The simple method of deep discharge is: after cycling to the electric run, then take out the battery and discharge each battery with a low voltage car bulb of 12V100W. Until the light is dimmed, or directly discharge the 12V100W low-voltage bulb of the car;

　　2. If no abnormality is found after the first charge and discharge and the second charge, the battery cover should be sealed as it is;

　　3. Repeated charging and discharging 2-3 times, the charging time of the battery can be extended to more than 6 hours. At this time, the battery or battery pack has been fully activated, and the capacity is effectively restored (more than 85%).

　　Precautions:

　　1. The repaired battery still needs to use the "repairer" for a long time, so as to ensure its multi-functional performance such as life extension; 2. The charger must be used in the matching charger. Due to the quality of the charger, the repair effect is also will be affected;

　　3. Inferior, unqualified batteries that do not meet the repair conditions cannot guarantee their efficacy when repaired;

　　4. The environmental working temperature of the repaired battery is preferably: °C≥15°C.
