BATTERIES FOR MILD HYBRID ELECTRIC VEHICLES, KPR Institute Engineering and Technology, Autonomous Engineering Institution, Coimbatore, India

The department of Electrical and Electronics Engineering organized a webinar on “Batteries for Mild Hybrid Electric Vehicles” on 19/04/2022 for faculty and students’ community. A heart-warming welcome was delivered by Dr.S.Shanmugam, Chairman, IE(I) Coimbatore Local Centre and Presidential address given by Dr.V.Kumar Chinnaiyan, Professor and Head, Department of EEE. Dr.C.Pazhanimuthu, AP (Sl.G) has introduced the guest speaker. Dr. Sundar Mayavan, Principal Scientist, Lead Acid Battery Section, CSIR-Central Electrochemical Research Institute, Karaikudi has delivered valuable presentation on
• Introduction to CSIR-BPTEC
• Batteries
• Electric Vehicles
• Batteries for Micro HEV
• Battery Charging and Discharging
• Issues with EV Batteries
• Batteries for Car, Solar Application and Inverters
• Battery Management System
In addition the resource person addressed the following topics such as Energy storage systems, usually batteries, are essential for all-electric vehicles, plug-in hybrid electric vehicles (PHEVs), and hybrid electric vehicles (HEVs). Hybrid vehicles are able to use electricity stored in the battery to power the motor. In this way, as the output of the battery increases, so too does the drive force of the motor. This achieves stronger acceleration with good response. Hybrid vehicles are also fitted with regenerative brakes that recover braking energy and store it as electrical energy. Enlarging the capacity of the battery makes it possible to store a greater amount of electricity more efficiently. This then increases the frequency of when the motor is powered by electricity, and thus the frequency of when the engine is generating electricity decreases. When taken together, fuel efficiency increases.
The resource person shared their wide experience in real time application of batteries. The vote of thanks was delivered by Dr.J.Krishnamoorthi, Honorary Secretary, IE(I) Coimbatore Local Centre. There were 70 participants attended the webinar and get benefited. The department of EEE thanks to the management and IE(I) Coimbatore Local Centre for providing this opportunity to conduct the webinar successfully.
