If you have electric vehicles in your fleet that you would like to utilize in your schedule, you should set the following preferences:
Batteries
Charging Management (optional)
In this article, you will learn how to configure the Batteries preference. It lets you define different types of batteries powering the vehicles in your fleet. Later in the EV scheduling process, they will be associated with specific charger types, charging profiles, and so on.
Note: This preference can also be made available in the Planning product as a part of the Timetable Optimization (TTO) Suite. The Planning version of the preference looks and works identically, so the instructions in this article still apply there.
Instructions
Accessing the preference
Open Preferences.
Switch to the All tab underneath the search bar.
In the Electric Vehicles section, click Batteries.
Setting basic parameters
Hover over the + Battery button and click + New Battery.
Set the basic parameters of the battery:
Name - the battery will be referred to by this name in other EV preferences;
Capacity (in kWh) - the amount of energy that the battery can store under standard operating conditions;
Minimum State of Charge (SoC) - the minimal amount of energy (in %) that must remain in the battery at any given time.
Setting overnight charging parameters (optional)
(Optionally) to take overnight charging into account. fill out the following fields:
End-of-day state of charge (EOD SoC) - desired level of charge at the end of the day.
By - the time by which the battery should reach the EOD SoC.
Penalty - the added cost in case the set preference is violated. Note: it’s recommended to keep this value higher than the electricity cost and lower than the vehicle cost.
Set the maximum charging rate per state of charge. The charging rates can vary throughout the charging process. Standard batteries tend to charge slower when they’re almost dry as well as when they’re close to 100%. To account for this, you can create sections of SoC (like 0% to 30%, 30% to 60%, and so on) and set their maximum charging rate as shown below:
Note: later in the Charging profiles preference you will set the standard charging rate per profile. That rate will be limited by the values you set here.
Setting discharge rates
Set the Discharge rates:
Base rate is the baseline rate at which a battery is discharged. Use either the average discharge rate or the worst-case discharge rate.
Add exceptions when needed by clicking + Add Exception. You can set varying rates based on route, direction, average speed, start and end stops, and time of day.
Once done, click Save & Close or proceed to set up other preferences.
