Abstract
Battery bank comprises of ‘N’ No. of. Battery pack where the required cells are connected in parallel and each pack will be made to connect both in series and parallel combination to attain a required voltage. Multi Secondary Coaxial Winding Transformer is used to maintain the battery in balanced condition. During charging and discharging of battery, each battery pack is connected to the secondary winding of transformer including Electronic Switches, Temperature Sensor, Voltage & Current Sensor. The voltage, current and temperature sensor is used to measure the parameters of each pack, from which the state of the health, state of the charge and temperature of the battery can be calculated. The voltage induced in the primary side is based on the switching frequency & duty cycle of the MOSFET. To compensate the required voltage needed by the load, a boost converter is connected to the system on the primary side of the system where the transformer will be coupled. The output is connected to the inverter that produces power to drive a BLDC motor.
