Extended four points rechargeable battery

Today, rechargeable batteries have become a part of people's lives. They are widely used in various fields (such as mobile phones, computers, car startup, emergency lighting, etc.). However, for all users, the battery is almost equal to the equipment and brick that need to use the battery once the rechargeable battery is out of power. With the detachable battery more precious, the majority of users have to take care of their own "inventory." Fortunately, by following some simple and feasible rules during routine maintenance and charging, you can extend battery life.mobile power plant

Please don't use electricity

    Obviously, the battery will gradually wear out while using the battery. Do not use the battery frequently, then the battery will be slower. There is a way to minimize this unavoidable loss, which is to retain some of the power.

    If you need to put a lithium battery for a long time, keep at least 40% of the power. Lithium batteries do not lose as much as 30% of the electricity per month, just like nickel batteries, and only lose 5% to 10% of their electricity. Once the lithium battery is completely discharged, it will become very unstable. In order to prevent explosion during charging, the lithium battery has a self-destruct circuit built in. If the battery reaches the bottom, it will damage the battery.

Forget about recharging power

    Once you may have heard, rechargeable batteries have a "memory effect" - if you do not allow rechargeable batteries to experience the feeling of "full" to completely dead, they are likely to "forget" part of the charge.

    But now, forget about this. Some batteries do have memory properties, but only apply to nickel batteries. The most popular rechargeable batteries are lithium batteries, which are different from nickel batteries. When using a lithium battery, you need to keep at least half of your battery power, and you'll need more. A process from “full” to completely dead, will not help to extend the service life of lithium batteries. If it is done in the long term, it may even cause damage and shorten the battery life. The correct method is: discharge once a month completely for "Calibration".

    On the other hand, you certainly don't want to keep charging all the time, which will cause the battery to overheat. Fortunately, the charger can help - after the battery is fully charged (in fact it will not be fully charged), it will disconnect the battery from the charge. Disconnecting the charger before it reaches 100% allows the battery to work its best.

    If you really want to optimize battery life, it is recommended to keep the battery charge between 40% and 80% during use. Repeatedly micro-charging, although not as bad as having been “full” to completely dead, is not a good choice.

Keep the ambient temperature suitable and avoid direct sunlight

    Lithium battery also has a "die" - overheated. When the battery is overheated, the battery will quickly wear out whether or not you use it. At 0° Celsius, a lithium battery loses an average of 6% of its maximum annual power output; at 25°C, it loses 20%; at 40° Celsius, it reaches a staggering 35%. Of course, saving your phone in the refrigerator is not very practical. Be careful not to put the phone in a place where the temperature is too high.

Avoid wireless charging

    Although wireless charging is very convenient, there are also drawbacks. The inductive wireless charging technology used today generates a lot of unwanted heat. The process of wireless charging is also the process of heating the battery. So, for battery sake, you still have to use standard plug-in charging unless you need to use wireless charging for heating.

Do not overcharge the car battery when charging

It is normal for the car battery to lose power, but does everyone know how to charge the battery correctly? Today, the high-power emergency starter Xiaobian leads everyone to look at the battery charging precautions and the correct charging method. . The specific gravity of electrolyte drops below 1.2; in winter discharge exceeds 25%; summer discharge exceeds 50%; light is dim; when charging is weak, it should be charged. Some owners believe that fast charging can save time and it only takes 3-5 hours. Actually, fast charging just quickly activates the surface of the battery. In fact, the inside of the battery is not fully charged.mobile power plant

In addition to fast charging, there is a slow charging, charging time is 10-15 hours, those who have a deep battery loss must be slow charging, otherwise the charging time is not enough, the charge is insufficient, will directly affect the driving performance of the car. Although charging is a fairly simple operation, there are some considerations:

1. Wear protective clothing when charging lead-acid batteries.

2. When charging, there should be no spark near the battery and smoking is prohibited.

3. When charging one or more batteries in parallel, the charger voltage should not exceed 16V.

Accurate battery charging method

There are more and more electric devices on automobiles today. When the vehicle owners use these electric devices, they should try not to overload the batteries. Overloading the battery will reduce the life of the battery. It is important to have a correct battery charging method.

1. First, connect the positive pole of the battery to the positive pole of the power supply, and the negative pole of the battery to the negative pole of the power supply

2, the initial charge of two phases: first with the initial charge current to the electrolyte discharge bubble, single-cell voltage rose to 2.3 ~ 2.4V so far. Then, the current is reduced to 1/2 of the initial charge current, and the charge is continued to the electrolyte to release violent bubbles, which is stable for 3 hours than the continuous voltage. All charging time is about 45~65h.

3, the charging process should always measure the electrolyte temperature by the current halved, stop charging or cooling method, the temperature is controlled at 35 ~ 40 °C, the initial charge is completed, if the electrolyte specific gravity is not specified, the application of distilled water or specific gravity of 1.4 The electrolyte is adjusted. After adjustment, charge it for 2 hours until the specific gravity meets the regulations.

How to distinguish the quality of car emergency starting power

The DOCA emergency power supply for automobiles is a product that has been developing rapidly over the past few years. It can provide start-ups for automobiles and provide a source of supply for digital products such as mobile phones and notebooks. However, it is precisely because of the fierce sales of automotive emergency start-up power supplies. Currently, manufacturers of automotive emergency start-up power supplies on the market are springing up, and the quality of products produced by them is uneven. So how does a car emergency startup power differentiate between good and bad?

1, batteries.

The battery core is an indispensable part of the car's multi-functional emergency power supply. It can be said to be the core of the multifunctional emergency power supply for the entire vehicle. Therefore, its quality is a difference between the quality of our automotive emergency start-up power supply. We can judge its quality mainly through the aspects of capacity, working voltage, and charge and discharge cycle life.mobile power plant

2, security.

The car emergency starting power supply is an indispensable escort partner for those who have a car. Therefore, it is good or bad to distinguish the emergency starting power supply of a car. It is necessary to first look at the safety technology to achieve compliance. Because the level of safety is a very important criterion for distinguishing the quality of emergency power supply for a car, we can see if there is a reverse polarity protection, output short-circuit protection, over-voltage protection, over-current protection, etc. A number of global patent safety protection designs are designed to judge if the safety technology fails.

3, the circuit board.

Everyone should know that when charging the car for emergency power, it is usually connected through the circuit board and the wire. Therefore, the quality of the car determines the output quality of the car's multifunctional emergency power supply. Therefore, we must pay attention to the selection of its circuit board when distinguishing between the emergency power supply of the car. Only an excellent circuit board can give full play to the maximum performance of the car emergency starting power supply.

4, conversion efficiency.

In the automotive emergency starting power supply, its conversion efficiency is one of the more important criteria for judging whether the product conversion ability is good or bad, and the automobile emergency starting power supply with high conversion rate can provide users with longer battery life. At present, the conversion rate of domestic automotive emergency power supply is generally around 80~85%.

5, battery capacity.

Although the number of judging standards for the quality of emergency power supply for automobiles is not particularly large, it is also a selection criterion that distinguishes the quality of automotive starting power. The size of the battery capacity often determines the number of times the car is started and the longevity of the battery life. But this battery capacity does not mean that the bigger the better, but should look at the performance of various aspects of the product and then make the choice.

The core, safety, circuit board, conversion efficiency, and battery capacity of the car's emergency start-up power supply are the most important aspects in distinguishing the quality of the emergency power supply for a car. Of course, there may be some other factors, such as the design of the product.

How long is the cycle life of the car's emergency starting power supply?

Whether it is a mobile power source, a power source, or a battery, everyone cares about how long it lasts and how long it can last. The lifetime of a battery can be measured using the number of cycles it discharges. In order to measure how long the car can be used for an emergency power supply battery, the definition of the number of cycles is defined. The actual users use the ever-changing, because the tests with different conditions are not comparable, and for comparison, the cycle must be standardized. Definition of life.mobile power plant

The national standard stipulates the cycle life test conditions and requirements for the battery of the car emergency starting power supply: charging at a room temperature of 25°C for 150 minutes in a constant current and constant voltage mode 1C charging system, and discharging to a constant current 1C discharge system to 2.75V as a cycle When the discharge time is less than 36 minutes, the test is completed and the number of cycles must be greater than 300.

Explanation:

A. This definition stipulates that the test of cycle life is conducted in a deep-charge deep-discharge mode.

B. Specifies the cycle life. The capacity must still exceed 60% after more than 300 times after execution in this mode.

Another measure of cycle life is time. Some experts pointed out that the general DOCA automobile emergency starting power supply battery is often used in the case of automotive emergency starting power battery is 2 to 3 years, combined with the actual situation, such as 60% of the capacity for the end of life, plus the car emergency start The aging effect of the power battery, and then not everyone has a professional knowledge of it, so popular point, a car emergency starting power cycle life is generally about 2-3 years. Therefore, the user does not have to worry about the problem that the power supply he has purchased has a short service life.

Doing this well, your battery will be more durable

DOCA  Auto Emergency Power Supply Expert: The following 6 points are available for reference

1. Charge the battery to avoid "deep discharge". Riding an electric car should develop the habit of using it on the same day as the day of the day. Every day you ride, no matter how far away, it is best to fill the battery with electricity. Don't wait for the light to recharge.mobile power  plant

2. When the battery is charging in the car, the electric door lock should be closed. Do not charge the battery upside down. When charging, try to fill it once.

3. When it is not used for a long period of time, it is necessary to charge once every month, and it is necessary to store the electricity in the battery after it is fully charged. Do not store it in a state of depletion.

4. Use a dedicated charger for charging. Because the battery formula and technology are different, the technical requirements for the charger are not the same. Which type of charger to charge the battery of any brand is not the same. Therefore, do not mix chargers.

5, to protect the battery, the user can use with the charge, but can not use the rising voltage to drive, to prevent serious loss of power, the battery is dead, you should turn off the power riding.

6. When charging, do not stop charging immediately when the charging indicator light shows full power. It should be floated for 2 to 3 hours.

Where are the batteries?

When the environmental protection slogan shouts loudly, we need to constantly retrieve whether our behavior is in harmony with the slogan. Is it mixed with noise that carries certain commercial private goods?

As various spells against the evil of the environment have come onto the scene, electric cars with a dazzling coat have been spotlighted from time to time, and even have a taste of being a savior. The electric car does not drink petrol and diesel. There is no such exhaustible exhaust pipe behind the buttocks. The noise emitted when driving is also slightly whispered. It is not like the old car, like an old man, always coughing hard... It seems that no one can find it. Receiving the reason for electric cars, experts say that electric cars are "green cars, the prospects are promising," such as the rhetoric, how much it chisel, so we also understand the "limit licensing policy, pure electric cars are not What is the right way to limit purchases? It can be expected that a city full of charging piles will come.DOCA

Behind the extremely bright surface, is there any hidden danger? Undoubtedly, before the perpetual motion machine has been invented, any driving device must consume energy. Essentially, all the things that need to consume the earth's resources are a big-tailed wolf for the human environment. The electric energy of an electric vehicle is stored in a battery, and it is used to charge electric energy. It supplies energy to the drive motor and treats it as the liver and kidney of the entire vehicle. This is not an exaggeration. What's bad is that this thing is particularly short-lived, and its life span is far inferior to the life span of human organs, especially the widely used lead-acid batteries. The whole car looks quite new, far less than the end of the scrapping period. The decay of energy storage has lost the useful life of recycling, and it can only discard the old ones with new ones.mobile  power  plant

Yes, the exhaust of a conventional car is discharged into the sky. It allows us to eat enough of haze, but this time, the waste battery of an electric car can not be used for days, but it can only enter the ground, but it cannot be like a pile of ordinary. The living garbage slowly degrades and can no longer be eliminated for 10,000 years. So where should they go?

It is one of the good ideas in the minds of the Chinese people that soldiers will come to block and water. In the misty sky, people have come up with ways to live in plastic hoods. They can go shopping, wear masks and gas masks. So, what measures do we take to stabilize the scrap car batteries that have accumulated in astronomical numbers?

A friend who has been studying electric vehicle batteries for many years told me that, in fact, the drawbacks of vehicle batteries are not only the pollution problems of a large number of scrapped batteries, but also the terrible dangers in the manufacturing process of batteries: Lithium metal electrolytes in manufacturing materials are powerful. Flux, cobalt metal, and the like are all carcinogens; the impact of lithium-iron membrane materials necessary for the manufacture of batteries on organisms cannot be ignored; the large amount of carbon dioxide emissions generated during the production of batteries is equally terrible. That is, sodium-sulfur batteries, nickel-cadmium batteries, lithium batteries, and fuel cells are being developed, and contamination during their manufacture and use is still unavoidable. In addition to this, can you ignore the energy consumption of battery charging and power supply? Can we avoid the huge pollution in the process of refining and producing battery manufacturing materials? Can it be numb to increase the amount of power generation? Does the burning of coal and gas cause harm to the environment when it is consumed?

It is not enough to be alarmist or to waste food, but calmness and reason are needed at all times. When the environmental protection slogan shouts loudly, we need to constantly retrieve whether our behavior is in harmony with the slogan. Is it mixed with noise that carries certain commercial private goods? Walking on the street that day, I saw a beautiful new tram passing in front of me. I suddenly remembered that the bus that was directly driven by an electric motor had recently been equipped with a storage battery.

         Ongjia Automotive Emergency Power Supply has always been dedicated to battery recycling and environmental protection. It is hoped that the majority of riders can minimize their pollution of life and pollute the atmosphere, giving us a place to live together in a green earth.

Six principles, market-recognized multi-function car startup power supply

In fact, no one thought of the DOCA emergence of automotive emergency power supply in the market. It did bring convenience to many riders, but the appearance of a product always accompanied good and bad, and a shaped multi-function car The emergence of emergency power supplies must be designed to be fully displayed in front of consumers. So what are the principles to follow when it comes to market-approved multi-function car starters?

The following principles must be followed when designing a multifunctional car emergency starting power supply architecture:

1, heat.

Assume that in a practical situation where the temperature is high (>30°C), the air flow is not smooth, or even there is no air flow, we should design the heat dissipation according to the minimum efficiency of the DC-DC converter. Moreover, we also need to provide good air circulation conditions to dissipate heat so as to achieve the best heat dissipation conditions.

2, control costs.

In the design of a car's multi-functional emergency power supply, its cost is a factor that needs to be considered in the design process. Therefore, we can use the budget of a specific project to be a PCB type, a package that can be selected, and other design constraints, and simply design and trim the unoptimized conventional power supply.

3, layout and location.

The overall performance of a multi-purpose automotive emergency starting power supply will limit the layout of PCB components, structural design in power supply design, and the design of integrated power supplies that restrict high-chip integration. Therefore, when balancing the overall system performance, mechanical limitations, and costs of the car's multi-functional emergency power supply, the designer needs to start with the actual project requirements.

4, electromagnetic radiation.

As things change, electromagnetic radiation is gradually generated in the electric field. The frequency and radiation of its electric field determine its radiation intensity. A working circuit will be directly disturbed by other circuits. These negative effects are irreversible, so OEMs have established maximum electromagnetic emission limits for ECU units, reducing these negative impacts and making them within controllable limits.

5, voltage VIN range.

As we all know, the transient range of the 12V supply voltage can determine the input voltage range of the power conversion IC. Among them, the most common automotive emergency supply voltage range is 9V to 16V. However, due to environmental factors, conditional factors and other factors, the voltage of the vehicle may be ±100V when using the car's multifunctional emergency power supply. Therefore, the ISO 7637-1 industry standard defines the voltage fluctuation range of the car battery.power bank plant

6. Shutdown current (ISD) and quiescent operating current (IQ).

    If the number of automotive electronic control units rises sharply, the total current consumption of the vehicle battery will also increase rapidly. Therefore, OEMs generally begin to restrict the IQ of each ECU, which can ensure that the static operating current IQ is within the controllable range. For example, the requirements set by the EU are: 100μA/ECU, so the ECU's IQ of less than 100μA is typical of most EU automotive standards.

Therefore, if you want to be a qualified, standard automotive emergency power supply, as long as you follow the above six principles, you can certainly make any multi-functional emergency power supply available in the market. We always insist on these principles, and take the user's vital interests. To make the product, we have the hot start-up power supply for our car to be so popular in the market. A good company is to concentrate on making products and doing conscience products.
