What are the repair techniques for batteries?

Battery repair method technology 1. Pulse repair method: The better way to eliminate vulcanization of the battery is to use the pulse repair method. When repairing the battery, the instantaneous voltage of the pulse is generally based on the function of the product. The instantaneous voltage is between 60V and 300V. For example, the pulse voltage value of the product used for battery life extension is not too large. It is specially due to the pulse of the battery repair product. The 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, the battery repair time is relatively long, although the pulse voltage is very high, but The average voltage is not high, no harm to the human body, very safe. There are special pulse generators on the market, but you should pay attention to choosing one with good effect. The resonance between the pulse and the battery plate is very important. This depends on the pulse frequency and the width of the pulse. If the pulse frequency and amplitude are not enough, the effect of eliminating sulfuric acid crystallization will not be achieved. If the frequency and amplitude are too large, it will eliminate vulcanization and damage. Electrode plate, and the phenomenon of outgassing; meanwhile, there are many kinds of pulse waveforms, which can be displayed on the oscilloscope. 2. Strong current repair method The strong current repair method is a method of repairing the battery with long-lasting high voltage or high current during charging, and is mostly used when the effect of the pulse repair method is not obvious. First, the high-voltage repair method: This method is important to repair the battery with a charging voltage 1.3-1.5 times the nominal voltage of the battery. For example, a 36V battery is charged with a 48V charger under the condition of the same or close to the charging current. , The charging time must be controlled and not too long, otherwise the battery will generate heat due to gas evolution. 3. Full charge and full discharge repair method The full charge and full discharge repair method is a method to repair the battery after fully charging the battery and then fully discharging it. The full-charge and full-discharge repair method is important for repairing slightly damaged batteries. At the same time, this method can also effectively activate the deep active material of the battery and increase the battery capacity. 4. Water replenishment repair method The battery loss can be repaired by replenishing water. The purpose is to dilute the sulfuric acid with increased concentration to perform the electrolytic reaction normally. The method of replenishing water is relatively simple. Just open the upper cover of the battery, you can see that there are six round holes, inject a certain amount of distilled water into each round hole, and soak for more than 24 hours. 5. Regrouping repair method: Electric vehicle batteries are generally battery packs made up of several batteries in series. The damage of the battery is multifaceted. There may be damage to the battery in several aspects at the same time: Regarding the vulcanized battery, after repairing The use effect is good; however, the battery with the softened plate and the partition can be repaired immediately, because it is a physical injury, the reusable value is not great, the use time after repair is also very short, and the effect of repair will be even worse. .
