Electric Vehicle Charging Stations — Lesson 6

This lesson covers the concept of public chargers for electric vehicles, their types, and the need for standardization. It explains how public chargers work similarly to petrol pumps, allowing electric vehicles to connect, charge, pay, and leave. The lesson also discusses different types of chargers, including standalone chargers, slow charging stations, fast charging stations, and bulk charging stations. It further delves into the communication protocols between the vehicle and the charging station, and the charging station and the grid. The lesson also touches upon the standardization bodies and their efforts to standardize chargers, and the Bharat Charger for Indian electric vehicles.
