Performance Evaluation of Various Chemically Structured Battery Banks Commonly Used in Electric Vehicles Using Off-Board Chargers

Abstract

Several vehicle kinds have different power requirements; although some need rapid charging and others may travel a long time between charges, the longest battery lifetime is a common feature. The depth of discharge (DOD), operating current, and temperature are other factors that affect the battery. Chemical cell characteristics that were carefully considered while building battery banks for this function are included in the article. For the common battery bank in electric cars, a high-power density off-board charger with multiple outputs-based H-bridge converters are being developed. It is suggested that the converter serve as an AC/DC battery charger and transmit power from the power grid to the battery packs powering the system powertrain. Analysis and presentation of the effects of the suggested topology on the various batteries and control method on integrated charger power losses, efficiency, and power density.
