Electric Vehicles with Dual Batteries Made Easier with New Reconfigurable Power Converters

Abstract

There has been a meteoric rise in the demand for electric vehicles (EVs) powered by batteries recently. Anxieties about EV range and reliability are the main roadblocks to the industry's expansion. A new trend in electric vehicles, especially in the twowheeler market, is the use of dual batteries to tackle these issues. Two new programmable power converters that can integrate two batteries are shown in this research. When charging or traction, the converters let you use only one battery, or they may link the two batteries in parallel or parallel. You may connect the converters' outputs straight to the charger and traction inverter. The terminal potentials of the two batteries must be very close to one another for the parallel connection to work with minimal circulating currents. To do this, the converters that are being considered have a voltage balancing function. A non-isolated inverters charger system (ICS) incorporates the suggested converter to exhibit dual battery charging. State space averaging while small signal modeling were used to construct transfer functions in the system using the proposed converter, and the K-factor technique was used to build the requisite controllers. The efficacy of the suggested power converters is validated by the presentation of thorough MATLAB calculations and hardware trials.
