The battery will gradually fail during use with the use of time, usage habits, and its own performance. At present, car batteries are mostly lithium-ion batteries and lead-acid batteries, and the batteries will be damaged during the use of the car. Under normal circumstances, batteries have a certain service life.
Once used for more than a certain number of times or time, the batteries will begin to age, affecting the use. A method that tests, analyzes, maintains and replaces batteries. This article will tell you the right steps of how to fix battery to achieve longer life and cost savings.
1. The basic knowledge of how to fix battery
Battery repair has the advantages of easy availability of raw materials, low price and good reliability. To do a good job in the batteries maintenance instrument industry, we must first understand the principle of auto battery repair. To understand the principle of how to fix battery, you must first understand how car batteries work.
With the development of science and technology and the improvement of living standards, batteries are increasingly used in various fields of life, especially electric vehicles and automobiles. It refers to the fix of lead-acid batteries with a instrument.
It can mantain and reorganize the faults of lead-acid batteries to achieve the purpose of batteries reuse. Battery repair can restore some of the battery's performance to a level close to that of a new batteries in various ways. Generally speaking, the common faults of the battery include water loss, crystallization, and power loss, which affect battery life while making the electric car run not fast and not far.
2. Benefits of repair the batteries
The benefits for you to understand how to fix battery well are obvious and easy to see the achievements. Battery repair can extend battery life and improve efficiency. In addition, it can also reduce the waste of resources due to batteries damage. At the same time, since some batteries may be subjected to long-term non-use and self-discharge phenomena, battery repair can also prevent this.
● Extend batteries life
First, let's talk about the benefits of fixing batteries. First of all, battery maintenance can help us extend the life of our batteries. As the battery life increases, the electrolyte inside the batteries will gradually solidify, causing the battery to lose capacity. Battery maintenance can restore battery capacity in a variety of ways so it can work properly and improve battery life.
● Cost savings
Second, battery repair can help us save costs. Batteries are an essential item in our daily life, and if the batteries is broken, we usually choose to replace it with a new one. However, new batteries are more expensive and battery maintenance s are cheaper, so successful use of how to fix battery is able to assist us save the cost of buying a new one.
● Reduce environmental pollution
In addition, to fix the batteries can also reduce environmental pollution. Battery is a kind of waste that is easy to corrode and pollute. If the battery is discarded arbitrarily, it will cause great pollution to the environment. By repairing the batteries, we can use them as much as possible, thereby reducing batteries waste and reducing environmental pollution.
3. Drawbacks in how to fix battery process
● Operation success rate
However, there are some downsides to battery maintenance. First of all, doing so does not guarantee that the battery can be restored to its original state, and sometimes the repaired battery will not work properly. This means that we may have to do it several times, so that the final cost may exceed the cost of buying a new battery.
● Professional technical support
Secondly, to put the specific operation of how to fix battery in to practical requires professional technology and equipment. It is best to have a certain understanding of the internal structure and working principle of the battery before operation. If it is not operated properly, it may cause further damage to the battery, resulting in irreparable damage to the battery, or even harm to the human body.
● Potential damage
Finally, battery repairs can also affect battery performance and safety. Although battery maintenance can restore battery capacity, sometimes problems such as short circuits inside the battery occur, which can cause safety issues such as battery heating and smoking.
Therefore, the merits and demerits of how to fix battery are all shown. When choosing the ways to how to fix battery, we need to weigh the pros and cons and decide whether to adjust it according to the actual situation. At the same time, it is necessary to find battery stores nearby and choose a professional institution or personnel, follow the operating specifications, and ensure the safety and effectiveness of the battery.
4. How to tell which batteries need to be repaired
Common battery types are carbon-manganese batteries, alkaline batteries, lifepo4 battery, nickel-metal hydride batteries, lead-acid batteries, etc. When these batteries are in use, there will be some problems and battery maintenance is required. In general, low voltage, reduced capacity, etc. are the main reasons why batteries need to be repaired.
● Connection cable reason
If the internal wiring of the battery is loose or corroded, the battery will have poor contact, which will cause the electric vehicle to stop and go. In this case, the solution is also very simple. Find the loose place and connect it directly. If corrosion occurs, you must replace the new cable.
● One small cell failed
If a single small battery in the battery pack fails, then the entire battery cannot function normally. Take a 48V battery as an example. It consists of four small 12v batteries. If one 12v battery fails, the entire battery pack does not need to be replaced, and the problem can be solved by re-mating. However, it should be noted here that we must pay attention to the matching of new and old batteries.
● Vulcanization of the battery pack
If the entire battery pack has a vulcanization problem, then it will show that the battery is not durable and runs out of power. Includes battery testing, analysis, maintenance, replacement and other aspects. It mainly refers to testing the performance parameters of the battery, checking whether the internal circuit of the battery is normal, checking whether the battery shell is damaged or corroded. If an anomaly is found, it must be repaired or replaced.
5. Steps of how to fix battery safely
First of all, we need to know that batteries are divided into open batteries and sealed batteries, and the maintenance methods for different types of batteries are also different. Let's first look at the maintenance method of valve-regulated sealed batteries.
● Clean
Before maintaining the battery, first clean the dust on the surface of the repaired battery, and remove the stain and rust on the terminal. Then open the exhaust valve and observe the electrolyte inside the battery.
● Pry open the battery bay
Pry open the adhesive or heat-sealed battery cover and observe the inside of the battery. Check if it is made of black impurities. If there are obvious black turbid impurities, it means that the possibility of the battery being repaired is relatively small.
If there are no black turbid impurities, you need to wait 4 hours for the water to fully penetrate the battery. At the same time, add 0.1%~0.5% electrolyte to the battery, and there is just a flowing electrolyte on the battery. If the battery capacity decreases only due to long downtime, you do not need to do this step, and you can directly enter the following precharge.
● Perform constant voltage current limiting charging
Generally, 0.1C to 0.25C current is used for charging, and after 16.2V, the charging voltage is maintained by reducing the current. Stop charging until the charging current drops to 0.03C.
Note that when charging, there will be gas with electrolyte overflow from the exhaust hole. In order not to pollute the environment, the battery should be placed in a specific container. After charging, after the battery has been stationary for half an hour, measure the open circuit voltage of the battery. The voltage should be above 12 volts.
If the battery voltage is below 12 volts, especially below 10.8V, the battery may have an internal short circuit, and the battery has no maintenance value. Connect the cathode and anode outputs of the instrument to the cathode and anode poles of the battery, turn on the repairs instrument, and fix the battery. The first time should not be less than 48 hours.
● Capacity testing
Discharge the battery according to 0.1C current and record the discharge time. Its discharge current multiplied by the number of hours is the battery capacity. If the battery capacity reaches more than 70% of the nominal capacity, the maintenance is terminated.
If the capacity does not reach 70% of the nominal capacity, continue charging. Continue to fix after charging, generally, batteries that have been stored for one year need to be repaired twice before they can be restored to the state before overdue storage.
6. Properly extend battery life
The ultimate and optimal advise for extending battery life and performance so you can perform an operation on how to fix battery. Most lead-acid batteries for electric vehicles currently on the market have a service life of about two to three years. As time goes on, the battery life depletes accordingly. However, the owner can delay the decay of the battery in some correct ways when using and charging.
● Choice of battery
Choose high-quality batteries, avoid refurbished, second-hand and other defective batteries, and solve battery quality problems from the source.
● Matching charger
Electric vehicle charging should choose a matching charger, do not use a charger with too large or too small battery voltage. Only a matching charger can maximize battery efficiency.
● Charging habits
Note that the remaining 30% of the electric vehicle power must be charged to the electric vehicle, do not use the electric vehicle battery to recharge, or charge the electric vehicle every day, both of which are incorrect.
Try not to use fast charging stations on the street, electric vehicle charging is controlled for about six to eight hours in summer, and electric vehicles can be charged overnight in winter.
● Charging time
The charging time of electric vehicles should be basically controlled within 10 hours, and it is easy to damage the battery if the charging time is too long. Each charge should be charged before the battery is used up, so that the damage to the battery is relatively small, and the service life is longer. The key to the service life of electric vehicles is the rational use and maintenance of the battery.
7. Conclusion
When there is a problem with the electric vehicle battery, if you do not want to try the above maintenance methods, you can choose to go to a professional shop first. They know how to fix battery.
When the battery fails and the battery life expires, replacing the new battery is the only positive solution. In short, how to fix battery right has a very important impact on battery life and efficiency. Proper maintenance can greatly extend battery life, improve battery efficiency, and reduce waste of resources.
