Intelligent Management Battery Backupups

UPS battery backupUps is mainly to prevent power failure of digital products during long-term use. It is a battery backupUps. It is different from the general battery backupUps,which uses four standard AA alkaline batteries. It needs to be shut down for replacement. UPS battery backupUps should belong to mobile power supply in a broad sense. Generally, 18650 lithium-ion batteries or lithium-polymer batteries are used as battery packs to connect charging wires and adapters to achieve continuous functions when digital products are powerless.

The main advantage of uninterruptible power supply is its uninterrupted power supply capability. When the AC input of municipal power is normal, UPS rectifies AC to DC, and then inverts DC to stable AC without impurities, which is used for the later load. Once the AC input of city power is abnormal, such as under-voltage or power failure or abnormal frequency, UPS will turn on the energy-storage battery backupUps, and the rectifier circuit of UPS will turn off. Correspondingly, the DC current of the battery will be inverted into a stable AC without impurities, which will continue to be used for the later load. This is the origin of uninterrupted power supply capability of UPS.

Of course, the uninterrupted power supply time of UPS is not unlimited, which is limited by the storage energy of the battery itself. What if AC power failure occurs? So in the precious time of UPS battery power supply, what you need to do is to quickly restore AC, such as starting standby AC circuit, starting oil engine power generation. If there is no other solution, you can only urgently save the results of labor, and wait for AC to return to normal before continuing.

Twenty-four years have passed. Time flies, day and night changes. No matter how the situation changes, the concept of "benefiting the people with the best batteries, touching clients with the best service" remains unchanged. Only battery of dongjin group an do this.

Looking at the history of the battery industry, you will find only powerful enterprises remain in dozens of brands in in a new round of reshuffle. Dongjin Group, the veteran batteries in this field shows its outstanding quality strength every time. In 2012, dongjin group invested 500 million yuan in establishing Jiangxi Dongjin New Energy Co., Ltd. in Ji'an, Jiangxi Province. It played a leading role in both brand influence and productivity improvement. In addition to focusing on building domestic sales channels, we should formulate a differentiation strategy, focus on the global market, and lay out the international market. Our products are exported to more than 50 countries and regions in Israel, Afghanistan, North America, South America, Asia, Middle East and South Africa. Among them, "Dongjin" and "Jinfeng" brands have become the leading brands in the local market. Compared with the same type of batteries, they occupy an absolute market share.

Under the new situation, new changes and adjustments have taken place in the battery energy industry. Dongjin Group, which is well versed in this theory, has been adapting to the trend of development, constantly adjusting its own structure and formulating a two-step marketing strategy: In the domestic market, we should set up professional R&D, production and sales teams, introduce modern equipment, increase control over product quality and technology R&D, and stabilize the domestic market with the advantages of quality and service.

The international market is based on the changes of the global new energy environment and the objective environment of oversupply in the domestic market. Top leaders of Dongjin Group decided to continue to invest more and build the largest battery production base in Bangladesh in December. At that time, the group's daily capacity of nearly 30,000 batteries can be completely digested by foreign trade orders. Domestic and foreign markets are combined to complement each other. It plays back into the attack and defend the action. This makes Dongjin present a unique brand image.

According to the senior management of the group, on the basis of its original strength, Dongjin Group will set up a brand new team, marketing model, product system and nanny-style service system at the end of 2016 to return to the domestic and foreign markets and re-establish the brand value of the enterprise. With the new situation, new environment and new changes, battery of Dongjin group is showing its strong vitality.

Many types of adapters can be used to charge lithium-ion batteries and power the system, and the electrical specifications of each rechargeable lithium battery are usually different. This requires system designers to build portable devices, which meet the safety and reliability requirements when using different adapters. Enhance robust security performance. Dongjin fully integrates input overvoltage, input overcurrent, battery overvoltage and reverse input polarity protection, which can significantly improve the safety of battery power supply system.

The ultimate purpose of parallel lithium battery of rechargeable lithium batteries is to increase capacity. Therefore, parallel lithium battery has some different characteristics in design compared with single lithium batteries, mainly reflected in the consistency of charging current design and parallel batteries.

Generally speaking, the characteristics of parallel lithium batteries are as follows: the voltage is constant, the capacity of batteries is added together, the internal resistance is reduced, and the power supply time is prolonged. The core content of parallel charging is the magnitude and function of parallel current. According to the theory of parallel connection, the trunk current equals the sum of all branch currents. Therefore, in order to achieve the same charging efficiency as a single lithium battery, the charging current should be the sum of the current of N lithium batteries.

Under the formula of I = U / R, this design is reasonable. However, the internal resistance of parallel batteries will also change. According to the formula of parallel internal resistance, the total internal resistance of two parallel lithium batteries is equal to the ratio of the product of internal resistance of two batteries to the sum of their internal resistance, and the parallel resistance will decrease with the increase of the number of parallel batteries. Therefore, the efficiency of parallel charging of lithium batteries can be realized on the basis that the current of lithium batteries in parallel is less than the sum of the current of N lithium batteries in parallel.

Generally, after parallel connection of lithium batteries, there will be a charge protection chip to protect the lithium batteries. As one of the excellent manufacturers of rechargeable lithium batteries, battery of Dongjin has fully considered the changes of lithium batteries after parallel connection, and also designed the current and selected the batteries according to the above requirements. Therefore, users need to charge lithium batteries on time according to the instructions of parallel lithium batteries, so as to avoid possible damage to batteries caused by incorrect charging methods.

As we all know, mobile phones, laptops, small cameras and so on all involve the application and development prospect of lithium battery, and more and more countries use the batteries for military purposes. The application shows that lithium battery is an ideal small green power supply.

The application and development prospect of lithium battery will expand rapidly in the next five years. The application and development prospect of lithium battery is mainly divided into three parts: consumer electronic products, electric vehicles and industrial energy storage. We can find that application focus of lithium batteries is at the stage of development from small batteries market of consumer electronic products to power batteries market of electric vehicles and industrial energy storage. The order is: consumer electronic products market electric vehicles market industrial energy storage market.

In emerging markets such as tablets, electric vehicles (PHEV + EV) and home energy storage, some lithium-ion batteries are the best choice, while others are the first choice. In the market of power grid energy storage which has not yet arisen, the related demonstration operation projects have been carried out at present.

Lithium-ion batteries are gaining ground in the market mainly because of their rapidly declining prices. In terms of performance, lithium-ion batteries are superior to lead-acid batteries, nickel-cadmium batteries, nickel-hydrogen batteries and other major competitors. Through the advantages of performance, lithium-ion batteries gradually expand the market scale. The growth of demand directly leads to the expansion of production capacity and the reduction of manufacturing costs, which in turn stimulates further growth of market demand. In this way, the lithium battery application industry has embarked on a virtuous cycle of development.

Main Characteristics of Lithium Batteries

The lithium battery advantages are large capacity and high working voltage. The capacity is twice as large as that of the same nickel-cadmium battery, which is more suitable for long-term communication. The voltage of lithium ion is 3.6v, which is three times as high as that of nickel-cadmium and nickel-hydrogen batteries. Charge retention ability is strong, allowing a wide range of operating temperature. After 30 days of storage in open circuit mode at (20 +5) (?) C, the discharge capacity of lithium-ion batteries at room temperature is more than 85% of the rated capacity. Lithium-ion batteries have excellent discharge performance at high and low temperatures, and can work at - 20 ~+55 (?) C. The discharge performance at high temperature is better than that of other batteries.

Long cycle life. Carbon anode is used in lithium-ion batteries. During charging and discharging, the carbon anode will not produce dendritic lithium, which can avoid damage to the inner dendritic lithium short-circuit ears of batteries. After 1200 consecutive charges and discharges, the capacity of the battery is still not less than 60% of the rated value, which is much higher than other types of batteries and has long-term economic use.

It has high safety and can charge and discharge safely and quickly. Compared with metal lithium batteries, lithium-ion batteries have the characteristics of short circuit resistance, overcharge resistance, overdischarge resistance, impact resistance (10 kg weight falling freely from 1 m height), anti-vibration, shooting, needling (penetration), non-fire and non-explosion. Because its anode uses special carbon electrode instead of metal lithium electrode, it allows rapid discharge and can charge and discharge at a charge rate of 1c. So the security performance is greatly improved.

No environmental pollution. Batteries do not contain harmful substances such as cadmium, lead and mercury, which is a clean "green" chemical energy without memory effect. It can be repeatedly charged and discharged at any time. Especially in emergencies, it shows excellent performance.

It has small volume, light weight and high specific energy. Usually, the specific energy of lithium ion batteries can be more than twice that of nickel-cadmium batteries. Compared with the same capacity nickel-cadmium batteries, the volume and weight of lithium ion batteries can be reduced by 30% and 50%, which is conducive to the miniaturization and lightweight of convenient electronic equipment.
