Can bulge battery also be used?

In recent years, the safety of batteries has been a topic of constant concern. Although battery technology is constantly improving, safety hazards still exist. Today, we will analyze the three types of electric vehicle batteries, mobile phone batteries, and electric vehicle batteries that are close to our lives to analyze the causes of battery bulge and how we should deal with them after battery bulge.

First, the electric car battery bulge

Battery is the core component of electric vehicles, is the heart of the car, It is necessary to take good care of it, and it can use for a long time, "longevity" make it effective. Pay attention to small details at ordinary times, cannot be ignored, especially the weather warming, battery easy drum filling distention let its end of life, "killed" in advance. Battery will beat for the following reasons:

1. The reason for the poor quality of the charger.

The price war, the charger quality all the way down, the inferior plank, renovation or inferior components, fever, inaccurate parameter drift and the charging pressure limiting out of control, the battery internal drum filling gas extrusion in battery shell deformation crack and even explode.

Response: the battery must be paired with a pair of good charger, internal cooling plate, protective plate, radiator fan, prevent water loss current limiting function, have overcharge protection device, once the overcharge, the charger automatically cut off the power and stop to recharge the battery, in case of no conversion in the process of charging the green light to cell damage or fire accident.

2, charging time is too long.

Some users charge no concept of time, thought with full automatic filling stop is ignored, or even two days and two nights, used to rise, charging for a long time, the battery life will be threatened, if excessive charging will lead to a large number of gas scouring pad, lead to fall off inside the battery active substances, shorten the battery life and make a battery filtration speed, affect the electrolyte decomposition, the battery temperature rise, make the drum filling!

Response: general electric vehicle charging six to eight hours in summer, winter 8 to 10 hours, do not overcharge for long, if more than 10-12 hours the same lamp, please help repair master.

3. The cause of internal battery failure.

Internal battery plate group have quality problem, micro short circuit, lack of acid leakage, water shortage, cause thermal runaway, make the battery internal pressure big and couldn't release the pressure relief valve, exhaust valve hole blockage, internal gas pressure lead to the battery shell deformation, crack distention. Additional battery life in two years or so, use two years battery plus the hot weather will generally due to water loss lack of fluid, it is easy to appear has been charging the red light did not turn light, charge the battery for a long time.

Coping methods: when the charger (10 hours not turn lights please go to the repair shop for maintenance, if charging 8-10 hours unplug chargers after pulling out the plug in from the same lamps in with light changes, is likely to be battery not line, if battery mileage run are ok, please give the battery charging liquid supplement, or add a timer, in case of drum, also could be one of the battery has a short circuit phenomenon or mileage is very short, replace the battery!

4. The problem of the charging environment. Charging environment is best 25 degrees or so, especially in rural areas there are a lot of families will charge electric car in the yard, the sun, hot weather, plus the charger work to generate heat, enveloped would result in higher inside the battery narrow surface temperature, cooling slowly, hot cell surface protection shell, increasing heat, to make the battery "stomach".

Response: never recharged at high temperatures, want to choose a cool ventilated place.

5. Often use the cause of the rapid charging stations.

Fast charging station is actually use the large current charging, its charging current 6-10 times higher than ordinary charger, have effects on large current charging the battery life, serious than electric vehicle battery charging load, persecution to the battery internal structure, often used in the large current charging environment, consumption of battery internal resistance electric current is calorific, lead to battery water loss, speed up cell ageing, plate buckling deformation, acid concentration increases, for a long time because of water loss and ballooning.

6. The reason for the use of the charger. Forgetting to bring a charger, just borrow one, or use a few electric car chargers in your home. This is a common phenomenon. Each electric vehicle battery brand has its own interface, current value, different electric cars may be charging voltage, charging current, natural charging time and charging efficiency is different also, with the charger, battery, charger, lack of electricity, small battery, charger, charging, thermal runaway, battery bulge.

Response: the battery and charger must match, not misuse.

Second, mobile phone battery bulge

Believe there are a lot of friends met mobile phone panels bulge, if bad word is difficult to put nearly panels slot, the mobile phone panels bulge after the use of mobile phones can let a person feel afraid, usually mobile phone panels appear this kind of circumstance is likely because the battery suffered some damage, in the process of charging mobile phone panels inside will produce some small amounts of gases, excessive charging can also lead to cell phone panels bulge, so what are the main cause of the panels bulge? What kind of solution is there?

(1) Reasons for mobile phone battery bulge

1, overcharge, because there is a small circuit board, battery main protection effect to the batteries, when through the charger will automatically disconnect, stop charging or discharging. In order to increase the battery capacity, some manufacturers set the battery's limiting voltage slightly higher, which will cause the battery to overcharge, because most of the charger does not have overcharge protection, and it relies entirely on the internal circuit of the battery to protect it.

2, the charging current is too large, the battery internal only for short circuit protection circuit, large current charging the battery, especially the fast electrical appliances.

3, the quality problem of the battery itself is a key part of the batteries, battery manufacturers in order to save the cost to attract market, adopted the inferior batteries.

(2) Solution for mobile phone bulge

1, please do not continue to use the bulge cell, a bulge, try to timely replace new battery. Try not to rely on the Internet to teach some of the ways to continue to use the battery.

2, at ordinary times, don't play with mobile phones, while charging. Stick to the battery condition regularly, in order to avoid a dangerous situation.

3, at ordinary times, when charging, pay attention to the choice of the charger, for example, the charging voltage of the battery is 3.7 v, limiting voltage 4.2 v, as far as possible, do not choose more than the voltage of the charger, to maintain a constant current is best.

4, choose the battery produced by large manufacturers, so the quality is relatively reliable. Mainly, or the degree of damage to the battery in your usual habits, you should pay more attention.

5, if the phone battery have been filled out, is to use your fingers to find the gap battery (cell phone battery back close to the mobile phone charge electrodes, press down a bit soft), use for to poke a hole and let the air out.

Third, car battery bulge

1, when charging the battery is the lead sulfate on the positive and negative plates and the water in the electrolyte chemical reaction, so that the positive plate back into lead oxide, negative plate back into pure lead, when more than the single battery voltage is 2.3 V, the battery will product gas (lead calcium plate analysis of gas voltage of 2.3 V, lead, antimony, plate chromatography gas voltage of 2.35 V). Everyone knows that when the water is boiled, the water vapor is very hot, and the power is also very large. You can start a train (steam car). This theory is to use our battery is the same, when the gas chromatography, the battery temperature will increase, at the same time, if a large amount of gas will cause the battery internal analysis did not have enough space to store these gases, will cause the battery to bulge.

2, the internal resistance of the battery is too high. When the internal resistance of a battery is too high, when the current is constant, the voltage will be high (voltage = current * resistance). What we can see is that the red light has not jumped to the battery when it is charged normally. It is very hot, that is, the battery has not reached the charging voltage, and it will be degassed in advance!

3, electric car charger is not in conformity with the requirements. When we use electric car charger parameters above our battery rated parameters such as voltage and current situation, it is possible to the battery charged drum!

Above is the reason for the phone's battery bulge and the corresponding solutions introduced for you. Battery bulge most reason is actually in the process of using improper operation, the charging method is wrong. Therefore, we should be in the process of daily use in strict accordance with the instructions and the right operation method of charging. Finally remind everyone, no matter which kind of battery has a bulging problem, you should contact the manufacturer for replacement. It should not be used any more to avoid potential safety hazards.
