Introduction to the working principle of battery power and its use



1. How battery power works

The battery power is a device that converts chemical energy into electrical energy, including batteries, transformer rectifier and voltage stabilizers. The battery itself does not have electricity, only battery power can provide current.


Therefore, battery power and ordinary power are different concepts. The battery power supplies are generally composed of a rectifier, lithium-ion battery, inverter, static switch and control system.

Usually, an in-line power is used. It first converts the AC power input from the mains into a stable DC power, supplies lithium-ion batteries and inverters, and then is converted into a stable, high-quality AC power source through the inverter. It completely eliminates any power problems that may occur with the input supply.

There is an automatic bypass function when battery power system itself fails. When it is necessary to overhaul, manual bypass can be used to ensure that maintenance and battery power do not affect each other.

2. The difference between battery and power supply

A battery is a portable battery power source, which is a device that converts chemical energy into electrical energy. A battery typically consists of one or more cells, each containing a cathode, an anode, and an electrolyte. When battery is connected to the circuit, a chemical reaction occurs between the cathode and anode to produce a flow of electrons and current.

Batteries can be used in a variety of devices, such as mobile phones, laptops, alarm clocks, electric vehicles, radios, and many more. Battery power include batteries. Batteries are just one type of battery power. Also, battery power include batteries, transformers, rectifiers, and voltage stabilizers.

The difference between battery and power supply


For example, battery power in the computer is a combination of transformers, rectifiers, voltage regulators, circuits, fans and so on, which does not have electricity itself. And alternating current for household appliances are called battery powers.

Batteries, as the name implies, are devices that store electrical energy, including non-rechargeable dry batteries, including battery used in flashlights, radios, quartz clocks, etc., nickel-metal hydride button batteries for electronic watches, hearing aids, etc.

Rechargeable batteries for cars, desktop computers, and portable torches, nickel-metal hydride batteries for gauges and razors, 7 or even smaller models for pocket radios, and the popular lithium-ion polymer as a raw material for mobile phones. The 18650 battery has many advantages as a power source.

● Portability

The battery can be easily carried, making it ideal for mobile devices.

● Rechargeability

Many batteries can be recharged repeatedly, so they can be reused, reducing the amount of waste.

● High energy density

Some battery types have a high energy density, so they can provide longer use. However, the disadvantages lie in:

● Limited life

The battery only lasts a certain amount of time and then needs to be replaced or recharged.

● Irreversibility

Some battery types cannot be recycled, so they may pollute the environment.

● High cost

The cost of some battery types is relatively high, so it may increase the total cost of maintaining and disposing of them. In order to extend the life of battery and ensure its safe use, the following are some recommended maintenance practices for battery care and handling. You can also go to the battery stores nearby for consultation.

The advantages of batteries as power source

  • Avoid overcharging, which may damage battery.
  • Store battery in a dry and suitable place at a suitable temperature. High temperatures and humidity may affect the performance of the battery.
  • Regular use of battery for a long time without using it may cause the battery to fail.
  • Disposal recycling, many regions have battery recycling programs that can take used batteries to designated recycling sites.
  • Dispose properly and do not throw battery into the trash or fire, which may cause the battery to leak or explode.

3. Classification of battery power

● Portable energy storage

It is a small energy storage device with a built-in lithium-ion battery that can stably output AC or DC voltage. Compared to mobile power, it can supply power to high-power household appliances, and can also replace traditional small fuel generators to provide power for emergency disaster response and outdoor operations.

Compared to mobile power, it is equipped with more types of interfaces, such as USB, Type-C, and PD, and supports car charging and solar panel charging. Portable storage is developing with high capacity and power, which can cover more mobile application scenarios with the support of powerful functions.

● Uninterruptible UPS power

It is a constant voltage and constant frequency uninterruptible power containing energy storage device and inverter as the main component. Its main function is to reliably and uninterruptedly power to computer network systems or other power electronic equipment through the UPS system.

● EPS emergency power

It is an emergency power device that allows short-term power interruptions. EPS emergency power system mainly includes a rectifier charger, battery pack, inverter, mutual investment device and system controller.

● Rectifier charger

The function is to realize the timely charging of battery pack when the input is normal. The function of the inverter is to convert the DC power stored in battery pack into AC power output when the utility power is abnormal and to supply stable and continuous power to the load equipment.

Classification of battery power


● Car emergency start power

Use to start the car with a fire. Its special function is to start the car when the car loses power or cannot be started for other reasons. At the same time, the inflatable pump is combined with emergency power, outdoor lighting and other functions, which is one of the necessary products for outdoor travel. This kind of battery power used lead-acid batteries in the early days, and now the vast majority of them use high-rate lifepo4 battery.

They also integrate the functions of mobile power and charging, and battery capacity is not much. Lightweight and portable. The automotive emergency starting power of lead-acid batteries is more traditional, using maintenance-free lead-acid batteries, which have greater quality and volume, and the corresponding battery capacity, starting current, etc. will be relatively large.

Such products are generally equipped with an inflatable pump, and there are functions such as overcurrent, overload, overcharge and reverse polarity indication protection that can charge various electronic products. Some products also have functions such as inverters.

Lithium-polymer automotive emergency start power supplies are relatively trendy and have recently appeared, with a light weight and small size that can be mastered in one hand. Such products are generally not equipped with an inflatable pump, have an overcharge shutdown function, and have a relatively powerful lighting function that can supply power to various electronic products.

4. The usage range of battery power

● Banking system

UPS power requirements for banks are generally very. The banking system is the largest user of battery power, and the use of UPS lithium-ion battery energy storage in the future banking system will be a development trend.

● Medical equipment

There are many kinds of medical equipment used in hospitals, and the power is generally relatively large, resulting in large fluctuations in the frequency of electricity consumption in hospitals and harsh electricity environments.

The usage range of battery power


● Data center

The ability to maximize the use of existing space and minimize power cooling energy consumption. The battery power is the key to dealing with these problems because of its excellent performance.

● Industrial equipment

The industrial-grade battery power has super environmental adaptability and meets the test of harsh environments with comprehensive high-performance performance. Effectively guard against high frequencies in the power grid, alert to the harm of overvoltage in the power grid to the load, and ensure the reliable operation of key industrial processes and controls.

5. Conclusion

The battery power has many benefits and can be used as a charging device when the battery is dead. It can also charge the battery when there is electricity, and it is widely used in various fields. In addition, the battery power has the advantages and great development prospects of the battery.
