Electric Vehicle Technology Lab

An Electric Vehicle Technology Lab has been set in the department. This lab is equipped with two EV 2 wheelers (Wokinawa make) with one 2 Wheeler cut section model where students are exposed to hands on practice of assembling and dismantling of all EV components. Besides, this lab houses 3 special sections with three wall display TV Units for Mechanical, Electrical and Electronics sections where students are imparted training and demo with EV power train live model, battery pack, traction motor and controller, battery management system and diagnostic tools.

 

The objective of the Electric Vehicle Technology (EVT) lab is to provide hands-on practical training, skill development, EV internships, and research and development support across a wide range of EV technologies. This learning facility is dedicated to accelerating research and development in areas such as EV design, motor control, battery management systems, chargers, embedded systems, IoT, and automotive electronics. By enhancing learners’ skills, the lab aims to create opportunities and contribute to sustainable employment for students.

RENEWABLE ENERGY LAB

The Renewable Energy Lab is set up with PV solar panels, solar off-grid setup, solar nano-grid to study the parameters of solar PV system using MPPT and PWM controller. The lab is also equipped with 500watt field model wind turbine, a vertical axis Tulip model and a blade less suction model for students study and training on the renewable energy technology.

 

Students will explore renewable energy, understanding its benefits in this laboratory compared to the risks associated with non-renewable energy sources. They will gain hands-on experience by building their own solar-powered and wind-powered turbine prototypes, while focusing on cost-efficiency. This mirrors the efforts of modern engineers who strive to reduce the costs of renewable energy, making it more attractive to the public.
