Battery whether liquid battery or poor liquid battery, if not used, must be fully charged storage! Otherwise, electrolytic ions in the cell can form irreversible chemical reactions. This battery is equivalent to premature death!
Discharge and charge is a chemical reaction process, the battery is good or bad and chemical reaction is completely or not related! Battery storage for a long time, because the partial loss of power part of the ion is unstable, parking will precipitate! Sulfated! The battery plate is intact and the battery is not charged. This is the damage caused by prolonged electricity. It can be repaired. After repair, the original storage capacity is guaranteed to be 80%.
Another damage is that the battery overdischarge! Like too much acceleration, too steep uphill, too big! At this time, the battery is prone to damage due to long-term high current discharge. This damage is fatal when the plate falls off! Because the large current is too fast chemical reaction, too fast electrolyte water formed gas, resulting in plate scouring! This is the same as our foot wash, a lot of bubbles below the foot wash! This damage is called plate softening! This can not be repaired. Only replaced.
Yours is the first case. The solution is this, the two contacts on the charging port are short connected, the time control should be fast, one second in this way! Don't be afraid of flares... .Usually take a metal object and just touch it. Then plug it in and see if the red light comes on.
The second method is to increase the charging voltage. You're not a professional. You probably don't have this kind of equipment... So let's go with the above... It's rechargeable, but the battery won't hold much power because it's sleeping... Charge it and run. Let it run out. Charge it again! How much can be run after this charge is the capacity of the battery..
Electric vehicles generally use valve-controlled sealed maintenance-free lead batteries, which have no special requirements for battery charging when they are first used, let alone activation. The battery has been turned into a relatively complete before leaving the factory, as long as it needs to be charged according to the power consumption situation.
Please refer to the following charging method.
When 100% is used up, the general charging time will be in 8~10 hours, not more than 12 hours (will have an impact on battery life), of course, it is not recommended to use up the electricity every time, the general recommendation is to charge the electricity at about 70%, the charging time is generally in 6~8 hours.
If you are on a short trip, the following are recommended
It can be recharged once a week when its daily electricity consumption is 10%.
It can be charged once every three days when its daily electricity consumption is 20%.
It can be charged once every two days when its daily electricity consumption is 30%.
When the daily electricity consumption is more than 40%, it can be charged once a day, and the charging time is generally about 6 hours under control.
When the battery of an electric vehicle runs out of power, the original charger may not work.
Can use a multimeter to measure the battery voltage, see how many volts, and then choose the appropriate charger according to the voltage.
For example, the 48V car put two or three months later, only about 29V, then the optional 36V charger to charge, and so on after the green car sub belt charge.
This time can be charged, but not necessarily full (charger change green), can be charged for 5~6 hours, and then ride to underpressure again, so repeated two or three times can be saved.
For example, 48V battery storage time is too long, only a dozen volts, it is necessary to use 24V charger, and then 36V, 48V slowly charged.
First add supplementary liquid to the battery, and then low current (1A) constant current slow charge, must not use large current, otherwise easy to cause explosion, the consequences are very serious. If shelved for more than a year, it is better not to use.
The method of dissolving large lead sulfate crystals by charging with high current and making them produce negative penetration.
It is found in the experiment that this kind of elimination vulcanization can only obtain temporary effect, and will cause increased water loss and positive plate softening in the process of elimination vulcanization, causing serious damage to the battery life, it is not easy to use.
Negative pulse
This method has been applied for more than 30 years of history, the principle is to add negative pulse in the charging process, to reduce the temperature rise of the battery has effect, but the repair effect of "vulcanization" is not obvious, its repair rate is 20%, currently used more, is obsolete products, often priced about 1300 ~ 1600 yuan.
Add active agent
Using chemical methods to eliminate lead sulfate crystals not only costs a lot, increases the internal resistance of the battery, but also changes the original structure of the electrolyte, and the repair period is shorter, its repair rate is about 45%.
High frequency pulse
The pulse wave is used to transform the lead sulfate crystals into reversible lead sulfate with fine crystals and high electrochemistry, so that it can normally participate in the chemical reaction of charge and discharge, and the repair rate is about 60%. Better than negative pulse effect. But because of its long repair time, need more than dozens of hours, even a week's time, low efficiency, serious "vulcanized" battery repair is not good, but the technology is simple, there are many manufacturers reuse, the market price is about 2000 yuan.
Combined resonant pulse
Reasonable control of the forefront of the repair pulse, the use of charging pulse of high harmonic and large lead sulfate crystal resonance method, in the repair process to eliminate the battery vulcanization, using this method can be used in the battery repair, repair efficiency is high, small damage to the battery, greatly reduce the lead-acid battery pollution to the environment, so that the battery life is extended, It is promising to reduce the huge cost of battery replacement. The disadvantage is that the equipment technology is complex, the cost is high, the pulse front control and the resonance technology is high. The market price is about -4 type (independent 4 charging and releasing) for 2200-3800 yuan, -20 type (independent 20 charging and releasing only) for 8500-15000 yuan.
