With the intensification of the energy crisis and the improvement of environmental protection awareness, people's demand for clean energy such as new energy vehicles, solar energy and wind energy is increasing. In these fields, Rechargeable Valve Regulated Lead Acid Battery (RVLAB), as an important energy storage device, has attracted wide attention. In this paper, the principle, characteristics, application and prospect of rechargeable valve-controlled lead-acid battery are introduced in detail.

a, the principle of plug-in valve control lead-acid battery

rechargeable valve-controlled lead-acid battery is a kind of the valve control technology, have rechargeable, discharge performance of lead acid battery. The principle is that during the charging process, the positive plate of the battery generates lead plumbate, and the negative plate generates pure lead; During discharge, lead and pure lead are converted to lead acid and lead, respectively. By controlling the charging and discharging process of the battery, the battery can be used repeatedly.

second, the characteristics of the rechargeable valve-controlled lead-acid battery

1. High energy density: The energy density of rechargeable valve-controlled lead-acid batteries is high, about 2 times that of ordinary lead-acid batteries, which can meet the energy needs of new energy vehicles and other fields.

2. Long life: The use of valve control technology effectively reduces the self-discharge and gas generation of the battery, so that the battery life has been significantly improved.

3. Good safety performance: there is a safety valve inside the battery, which can timely release the excess gas generated inside the battery to prevent the battery explosion.

4. Environment friendly: Rechargeable valve-controlled lead-acid battery has high recycling rate and small environmental pollution.

3, the application of plug-in valve control lead-acid battery

1. New energy vehicles: new energy vehicles have higher requirements for energy storage devices, and rechargeable valve-controlled lead-acid batteries have become the first choice for new energy vehicles because of their high energy density and long life.

2. Solar and wind power generation systems: Rechargeable valve-controlled lead-acid batteries can be used as energy storage devices for solar and wind power generation systems to achieve stable output of electric energy.

3. Uninterruptible power supply (UPS) : The rechargeable valve-controlled lead-acid battery has good charge and discharge performance and can be used as a key component of the uninterruptible power supply.

4. Power assist system: In the power assist system, the rechargeable valve-controlled lead-acid battery can achieve the peak load, energy storage and other functions of the power grid.
