Researchers examined how different electric vehicle batteries perform under various driving conditions to help design more efficient and cost-effective electric cars. They tested the batteries on different driving cycles in a simulation before real-life testing to understand battery life and efficiency. By evaluating batteries on international and Indian driving patterns, they found that battery performance varies based on the type of battery and driving conditions. They developed a control strategy for the vehicle's motor and used a specific modulation algorithm to enhance battery performance. The study calculated energy consumption and charging costs to compare the effectiveness of different electric vehicle batteries.
