TOPIC NAME - MATLAB/SIMULINK Simulation Onboard charger for 48 V batteries of EV (Two Wheeler)

2. Introduction
• In this Project we are going to make MATLAB/SIMULINK Simulation
Onboard charges for 48 V batteries of EV (Two Wheeler) .
• This project is totally matlab based. 48V EV charger is providing more
efficient power distribution throughout, optimising engine accessories and
other electronics on the vehicle.

3. Need of this project
• Electric vehicle manufacturers are starting to adopt 48-volt electrical
systems.
• The latest specialist EVs will be using components that more power,
additional torque, and – with automation and smart engineering – greater
intelligence.
• The potential applications of 48V are exciting, representing a huge
innovation in automotive design.With more technical capability, comes a
greater need for power.
