Learning Objectives

What is smart charging and vehicle-to-grid (V2G)?
Why do we need smart charging?
What are the advantages and disadvantages of V2G?
In which cases can smart charging can be applied?

SLIDE 3

Definition

Smart charging is a series of intelligent functionalities to control the EV charging power in order to create a flexible, sustainable, low cost and efficient charging environment.

SLIDE 4

Benefits of smart charging

Increase the flexibility of charging
Higher utilization rates of fixed assets
Efficient utilization of energy in distribution network
Make electric vehicles more sustainable
Provide new revenue streams to EV owners

SLIDE 6

V2G

Using the electric vehicle battery to feed power back to the

grid using a bidirectional EV charger

V2G = Vehicle to Grid
V2H = Vehicle to Home
V2B = Vehicle to Building
V2L = Vehicle to Load
..........
