  • What is a Solar battery and how does it work?

    What is a Solar battery and how does it work?

    Aug , 27 2021
    What is a Solar battery? A solar battery is an energy storage option for those with solar panel systems. With the increased use of solar power, solar batteries are more popular with homeowners who want to offset electricity costs and those living or camping off-grid. Solar generators and portable solar chargers are types of solar battery storage systems. While so...

  • What is the reason behind the thermal runaway phenomena of the VRLA battery?

    What is the reason behind the thermal runaway phenomena of the VRLA battery?

    Aug , 27 2021
    Thermal runaway is a phenomenon where the current flowing through the cell or battery on charge or overcharge causes the cell temperature to rise, which increases the current with a further rise in temperature. The appropriate charge voltage depends on the battery temperature (see below tables). A warmer battery requires a reduced voltage. If the voltage is not reduced, current accepted by the bat...

  • How does a battery recharge?

    How does a battery recharge?

    Aug , 27 2021
    The process is the same for all types of lead-acid batteries: flooded, gel and AGM. The actions that take place during discharge are the reverse of those that occur during charge. The discharged material on both plates is lead sulfate (PbSO4). When a charging voltage is applied, charge flow occurs. Electrons move in the metal parts; ions and water molecules move in the electrolyte. Chemical reacti...

  • Why does temperature have such a dramatic effect on VRLA batteries?

    Why does temperature have such a dramatic effect on VRLA batteries?

    Aug , 27 2021
    Temperature is a major factor in battery performance, shelf life, charging and voltage control. At higher temperatures there is dramatically more chemical activity inside a battery than at lower temperatures. The following charts graphically illustrate this fact. Typical Self-Discharge of VRLA Batteries at Different Temperatures AGM Charge and Float Voltages at Various Temperature Ranges Gel Charg...

  • AGM VS GEL VS FLOODED VRLA batteries- Advantages and Disadvantages of them

    AGM VS GEL VS FLOODED VRLA batteries- Advantages and Disadvantages of them

    Aug , 27 2021
    In the following we have tried to shortlist some advantages and disadvantages of the AGM batteries, GEL batteries and Flooded VRLA batteries. Gelled Electrolyte Advantages: • Totally maintenance-free • Air transportable • Spill proof/ leak proof • No corrosion • Superior deep cycle life • Installs upright or on side (side installation may lose about 10% capacity) • Ve...

  • VRLA battery charging method

    VRLA battery charging method

    Aug , 27 2021
    Proper charging is one of the most important factors to consider when using maintenance-free sealed lead acid batteries. Battery performance and service life will be directly affected by the efficiency of the charger selected. Charging methods are dependent on battery applications like main power application and standby / backup power application. Main power application (Cycle use): a) Standa...

  • What to do when you receive your VRLA batteries?

    What to do when you receive your VRLA batteries?

    Aug , 27 2021
    Preparation for System Installation The installation of the battery system involves a series of activities from planning and initial receipt through final checkout and warranty registration. As part of this preparation activity the installer should develop a system schematic diagram which identifies how the individual batteries are to be placed on the rack, interconnected and numbered. The cabling...

  • Safety concerns for 12V VRLA batteries installation

    Safety concerns for 12V VRLA batteries installation

    Aug , 27 2021
    Installation and servicing of the 12V VRLA battery should only be performed and supervised by personnel knowledgeable of lead acid batteries and required personal and equipment safety precautions. Keep unauthorized personnel away from the batteries and installation activity. Electrical Hazards Battery systems present a risk of electrical shock and high short circuit currents. The followi...

  • Using carbon as a negative additive in VRLA battery

    Using carbon as a negative additive in VRLA battery

    Aug , 27 2021
    Several types of carbon find various uses in many types of electrochemical power sources. In this article, we focus on implementations of its elemental forms in presently used lead-acid batteries, as well as potential future improvements to their construction that carbon can bring. Unique properties of carbon and a variety of its allotropes allow it to find a use in different parts of lead-acid ba...

  • Modeling process for the cost profile of a Energy Management System (EMS)

    Modeling process for the cost profile of a Energy Management System (EMS)

    Aug , 27 2021
    Modeling is an iterative process that starts with a first estimate of battery specification that is combined with the other inputs to the EMS to deliver a cost profile. It calculates the lifetime costs and operating revenue for a size of ESS. By repeating the process with a range of different sizes, it’s possible to identify the sweet spot, where the operator will find the optimum balance bet...
