Step 1: Check the appearance of the battery: Check the battery appearance is not intact. Checking the battery case without convex, night leak, disconnection, battery terminal corrosion, etc. Check the voltage of each battery every 20 minutes.
If the voltage of a single battery exceeds 15V, the battery has been vulcanized; if the voltage is less than 13V, the battery is shorted or reverse; (2) When discharging, use a multimetric table three times to measure the voltage of each battery, 10 minutes each time. If the voltage of a battery is lowered than other batteries, and less than 10 volts, the battery is the shortest discharge time of this battery. (3) Test the static voltage of a single battery (floating current).
When the voltage is zero, there are two possibilities: First, the battery is completely opened, the circuit is closed, the voltage is zero; the second is that the battery is placed too long, the voltage is as low as 1-2V, even zero. Third, check that the battery electrolyte is dehydrated: checking the electrolyte or loss of water. After charging the battery for 3-6 hours, touch the side of each battery case with hand.
If the battery is hot and hot, the battery is dead; if it is only hot, the temperature is about 40 degrees, when charging, the charger is always bright red light, indicating that the battery is seriously dehydrated; in addition, you can also turn on the battery cover, check the dehydration condition. Is the electrolyte not a black, can determine the quality of the panel. Open the battery cover, you can see six round holes.
Check the electrolyte color of each well. If it is black, it means that the lead powder on the plate is off, the battery is dead. (2) Battery maintenance method to discuss battery repair is not difficult.
For example, it is difficult to repair the entire battery (in addition to battery vulcanization). As long as one of the battery packs is physical damage, the effect of using the maintenance instrument is not clear, but it is necessary to separate the battery pack, repair a battery, which can not only test the type of battery damage, but also different maintenance methods, so The key to repair the battery is to repair a single battery (usually 12V). Here are some brief analysis: one.
Pulse repair method: Eliminate battery vulcanization is the use of pulse restoration. When repairing the battery, the transient voltage of the pulse is typically between 60V to 300V based on the functional requirements of the product. For example, the pulse voltage value of the product for extending battery life is not too large, especially because the pulse voltage value of the battery repair product may be too large (if the pulse voltage value is too large, it will damage the battery board), and the pulse voltage is high, the battery Short repair time, low pulse voltage, battery repair time is relatively long, although pulse instantaneous voltage is high, but uniform voltage is not high, no harm to the human body, very safe.
In terms of solid state, any insulating layer can be broken at a sufficiently high voltage. Once the insulating layer is broken, crude sulfate will present a conductive state. If a high pressure is applied to the insulating layer of the high resistivity, the lead crystals of large sulfate will also be broken down.
If the high pressure is short enough, the current is limited, when the insulating layer is broken, the charging current is not very large, and a lot of gas will not form. When the pulse width is short enough, the micro charge cannot simultaneously form a gas simultaneously when the pulse width is sufficiently short. Thereby achieving pulse elimination vulcanization.
There is a special pulse generator on the market, but you have to pay attention to the choice of a good pulse generator. The resonance between the pulses and the panel is very important, depending on the size and width of the pulse frequency. If the pulse frequency is not enough, the effect of eliminating the crystallization of sulfate cannot be reached.
If the frequency and amplitude are too large, it will damage the plate and the gas precipitation occurs. At the same time, there is also a variety of pulse waveforms on the oscilloscope. Good pulse wave can effectively penetrate the insulating layer without damaging the battery, and the ruptured sulfate chipide is reduced to an electrolyte.
Just like people's gravel. Is it effective in facing a big stone? It's easy to see. 2.
Mechanical repair method: The mechanical repair method is to repair the battery for a long time of the battery for a long time in charging, usually in the case where the pulse repair effect is not clear. First, a high-pressure restoration method: This method is tight to use the charging voltage to repair the battery nasm to repair the battery nominal voltage. For example, when the charging current of the 36V battery is constant or approaching, the charging time should be charged using a 48V charger, and the charging time should be appropriately measured.
It is not easy to be too long, otherwise the battery will heat due to gas precipitation. This method can repair the battery board with low softization, but if not improper use, it will damage the pressure point of the battery board. The second is a large current repair method: this approach is tightly repairs the battery with a charging current that is 1.
5-2.0 times higher than the general charging current. If the 20AH battery is charged with 3-4A charger, its advantages and disadvantages are the same as high pressure maintenance.
three. All-in-one discharge repair method: the full charge and full discharge repair method is to fully charge the battery, completely discharge, to repair the battery. The full full discharge repair method is tightly used to repair the lighter battery.
At the same time, this approach can also effectively activate the deep active substance of the battery and improve the capacity of the battery. For example, the key to this approach is to discharge the amount of sulfur, and the internal resistance is fully discharged, and each unit cell is discharged, and the charge and discharge is 1-2 times, and the battery capacity can be overexpressed. Needless to use all charge and full discharge repair methods.
Use at least once for half a year, use up to once every three months. Four. Method: It can be repaired by adding water in the water loss of the battery.
The purpose is to dilute sulfuric acid with a new concentration to carry out normal electrolytic reactions. Method is relatively simple. Just open the upper cover of the battery, you can see six round holes.
Inject a certain amount of distilled water into each circular hole, soak for more than 24 hours. The lotion can only be formulated with distilled water, and water cannot be formulated, including pure water, because the water of other ingredients contains various metal molecules, and it is easy to cause self-discharge to damage the battery.
