AGM Valve Regulated Batteries: Guardians of Efficient Energy Storage

AGM valve regulated battery, full name is liquid-absorbing glass fiber spacer valve regulated sealed battery, is a kind of storage battery made by special process. It revolutionizes the traditional open-ended battery with superior performance and reliability, and is widely used in the fields of ups uninterruptible power supply, emergency lighting, power communication, electric vehicles and so on. In this paper, the construction, working principle, performance characteristics and application areas of AGM valve regulated battery will be introduced in detail.


1. Structure

The AGM valve-regulated batteries are mainly composed of the positive plate, negative plate, spacer plate, electrolyte, sealing cap, and valve control system. Among them, the positive and negative plates are made of lead-calcium alloy material, which has better charging and discharging performance and corrosion resistance. The spacer plate is made of glass fiber material, which has high strength and good electrical performance. The electrolyte is sulfuric acid solution, which plays the role of conductivity and energy storage. The sealing cap and valve control system are then the key parts to ensure the safe operation of the battery.

2. Working Principle

The working principle of AGM valve-controlled battery is based on the charging and discharging process of lead-acid battery. During the charging process, the positive plate absorbs lead sulfate, the negative plate absorbs lead sulfate, and the concentration of sulfuric acid in the electrolyte gradually increases. During the discharge process, the lead sulfate on the positive and negative plates is converted to sulfuric acid, and the concentration of sulfuric acid in the electrolyte gradually decreases. AGM valve-controlled batteries automatically regulate the evaporation and gas discharge of the electrolyte through the valve control system to ensure that the battery maintains constant pressure and current during charging and discharging, thus realizing efficient and stable power output.

3、 performance characteristics

    1. High energy density: AGM valve-controlled batteries have a high energy density, the same volume and mass of the battery can store more power, thus reducing the size and weight of the system.

    2. Long life: AGM valve-regulated batteries are manufactured using a special process and have a long life. Under normal use conditions, the battery life can reach more than 5 years.

    3. High reliability: AGM valve-controlled batteries have excellent charging and discharging performance and voltage stability, which ensures the reliability of equipment operation.

    4. Good safety performance: AGM valve-regulated batteries adopt valve-controlled system, which effectively prevents overcharging and over-discharging of batteries and reduces the risk of battery explosion and fire.

    5. Environmentally friendly: AGM valve-regulated batteries are made of lead-acid material, which can be recycled. Meanwhile, the battery produces less exhaust gas during use, which is friendly to the environment.

4、Application Fields

The AGM valve-regulated batteries are widely used in the following fields due to their superior performance:

    1. UPS Uninterruptible Power Supply: Provide reliable power protection for critical loads and ensure that the equipments can be operated normally in the event of power interruption.

    2. Emergency Lighting: Provide timely and stable lighting power for public places.

    3. Power communication: Provide stable and reliable DC power supply for power system and communication equipment.

    4. Electric Vehicle: As the power source of electric vehicle, to meet the driving demand of the vehicle.

    5. Solar power generation system: Provide energy storage equipment for solar photovoltaic power generation system, improve the power generation efficiency of the system.

In short, AGM valve-regulated batteries play an important role in various fields by virtue of their unique structure, working principle and performance characteristics. With the continuous development of science and technology, it is believed that AGM valve-regulated batteries will have a wider range of applications and contribute to the progress of human society.
