ANALYSIS AND CHARGE CONTROL OF LITHIUM ION BATTERY WITH APPLICATION FOR OFF-GRID PV SYSTEM

Abstract

For the implementation of the PV micro grid, initially we designed the PV module. Once the PV module is designed we then decided to use P&O technique as an MPPT technique. The output pulse of the MPPT technique is then fed to the boost converter as gate pulse. The output of PV with dc to dc converter is then fed to DC grid from where the 3-phase Inverter with LC filter which converts the DC to 3-phase AC system and then is fed to load. Also the battery system with bidirectional controller is followed by a charge controller is also connected to DC micro grid so that the battery can charge or discharge as per the application.
