Electric Vehicle Battery Charging — Lesson 6

This lesson covers the various battery charging technologies used in electric vehicles (EVs). It delves into the four major charging schemes based on level voltage, current, power level, and charging time. The lesson also discusses different types of charging such as normal charging, opportunity charging, fast charging, and battery swapping. It further explains various charging algorithms like constant current charging, constant voltage charging, and multistage charging. The lesson also touches upon the concept of wireless power transfer and the role of battery management systems in EVs. For instance, it explains how a battery management system can estimate the state of charge, state of health, and state of power of a battery.
