  • Suitability of competing charging solutions in Genset applications

    Suitability of competing charging solutions in Genset applications

    Dec , 10 2021
    Instead of polyethylene, AGM type SLI batteries typically employ separators made of fiberglass. Because fiberglass does not oxidize like organic polyethylene, float charging at the battery manufacturer’s recommended float voltage is not inherently harmful to AGM type SLI batteries. Therefore, the intermittent charging method discussed is unlikely to increase the life of AGM type batteries. The dif...

    The structure and related advantages of the thyristor rectifier of the charger

    Mar , 28 2022
    Silicon controlled rectifier is a power control appliance based on thyristor (power electronic power device) and with intelligent digital control circuit as the core. It has many advantages such as high efficiency, no mechanical noise and wear, fast response speed, small size and light weight. The characteristics of the silicon controlled rectifier: it is "triggered". However, if a reverse voltage...

    Battery charging tutorial-Part 1

    Apr , 18 2022
    Current battery charging technology relies on microprocessors (computer chips) to recharge; using 3 stages (or 2 or 4 stages) regulated charging. These are the "smart chargers", and quality units generally are not found in discount stores. The three stages or steps in lead/acid battery charging are bulk, absorption, and float. Qualification or equalization is sometimes considered another stage. A ...

    Uninterruptible Power System-Use of Inverters & Chargers

    May , 09 2022
    If you already have a pretty good idea about the available methods for converting ac power to dc power, an inverter covers the other direction: changing dc into ac. Normally, when we speak of an inverter, we mean a device that generates line frequency power from a dc source, to power conventional ac-powered loads such as a personal computer, or industrial controls and instrumentation. A UPS integr...

    High Frequency / High Ripple Resonant Chargers: Good or Bad? (part-1)

    Jun , 13 2022
    Battery charging is a complex electrochemical process, in which the discharged electric energy is replenished from the electric power grid. This is accomplished using a battery charger, which is an electrical/electronic device that converts the incoming AC line voltage into a regulated DC voltage to meet the charging needs of the respective battery. In a series of articles we are going to explain ...

    What types of monitoring and recording devices are suited for high rate charging?

    Jun , 20 2022
    The higher the charging rate, the more critical it is to monitor the charging process to prevent permanent capacity loss. In efforts to preserve battery life, Fast and Opportunity charging incorporates a method of monitoring battery electrolyte temperature and/or internal resistance and adjusting charging current as necessary. Although these monitoring devices can have a very positive impact on ba...

    Do Ferro resonant chargers still have a place in battery charging?

    Aug , 15 2022
    One of the larger battery/charger companies selling chargers in the USA have announced that they are no longer manufacturing Ferro resonant chargers and have set 7/31/15 as the last date to accept orders.Is there something wrong with Ferro resonant charging that should make all charger companies follow that lead? Let’s consider Ferro resonant technology. The purpose of a Ferro resonant transformer...
