8.8.3 Sequential Charging Example

The following is a representation of a sequential charging scenario when three dispensers are used.
It is assumed that the bulk charge complete SoC is set as 85% and the interval between bulk charging
sessions is set as 30 minutes here. EV 2 was charging when EV 1 arrived and was connected. Automatically,
EV 1 enters bulk charging while EV 2 is placed in Queue 1, waiting for trickle charging. The rest of the
scenario is detailed below:

- EV 1 arrives and enters bulk charging
- EV 2 goes in Queue 1
- Once EV 1 reaches 85%, it stops charging
and then goes in Queue 1 after a new
charging request from the EV
- EV 2 resumes the trickle charge
- EV 3 arrives but not connected
- EV 3 is connected and goes in bulk charging
- EV 1 stays in Queue 1
- EV 2 stops charging and goes in Queue 2
after a new charging request from the EV
- EV 1 starts trickle charging and stays in
trickle charging for 15 minutes
- EV 2 goes in Queue 1
- EV 3 finishes bulk charging and goes in Queue
2 after a new charging request from the EV
- After 15 minutes, EV 1 stops charging and goes
in Queue 2 after a new charging request from
the EV
- EV 2 goes in trickle charging
- EV 3 goes in Queue 1
- EV 1 goes in Queue 1
- After 15 minutes, EV 2 stops charging and goes
in Queue 2 after a new charging request from
the EV
- EV 3 goes in trickle charging
- EV 1 goes to trickle charging
- EV 2 goes in Queue 1
- After 15 minutes, EV 3 stops charging and
goes in Queue 2 after a new charging request
from the EV
