    High Frequency / High Ripple Resonant Chargers: Good or Bad? (part-3)

    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 are some key practices for a Fast or Opportunity charge operation?

    Jun , 20 2022
    What are the operational implications of charging at a higher rate? Initial Cost: Initial charger investments may cost up to 5 times more than a conventional charger operation, especially if the charging system utilizes a dedicated charger for every battery. Infrastructure Change: Once committed to the Fast or Opportunity charge process, it can be very difficult to transition back to Conventional ...

    What is pulse charging and output power of a battery?

    Oct , 24 2022
    What is pulse charging? What is the impact on battery performance? Pulse charging generally adopts the method of charging and discharging, that is, charging for 5 seconds and discharging for 1 second, so that most of the oxygen generated during the charging process will be reduced to electrolyte under the discharge pulse. It not only limits the vaporization of the internal electrolyte, but also fo...
