EV Best Time Off-Peak in Weekly Energy Update Email Module

The EV Best Time Off-Peak in Weekly Energy Update (WEU) Email module can be included in Weekly Energy Update emails. This module explains to the reader when the best times are to charge their electric vehicle (EV) during off-peak hours. The module explains how this behavior can ease the strain on the grid.

This module should be included in the second EV-specific Weekly Energy Update email the customer receives, and then again once every six months to remind the customer about the best times to charge their EV.

Requirements

User Experience

This module includes:

Header: The header of the module tells the reader that the way they charge their EV matters. For example, "Your EV charging patterns matter"

Explanatory Statement: This statement tells the reader that changing their charging habits can help their community. The statement reads, "By charging during specific times of the day—not just avoiding peak demand—you can make your driving even greener and better for your community."

Tip 1: The first tip identifies the best time to charge. The header reads, "The best time to charge is <window 1>", and is followed by the statement "Make your EV driving even greener by charging midday when clean solar energy powers the grid."

Tip 2: The second tip identifies the next best time to charge. The header reads, "The next best time is <window 2>", and is followed by the statement "Charge during early morning hours when demand is low."

Tip 3: The third tip identifies times to avoid charging. The header reads, "Avoid starting to charge right at <TOU off-peak start>", and is followed by the statement "If you need to charge in the evening, try not to begin right at <Xpm>. This is the beginning of the low-cost hours for customers on UtilCo's <TOU Rate Plan Name> plan and a resulting surge in appliance electricity usage."

Tip 2: The second tip is "Set a delayed start time, and is followed by the statement "Help avoid straining the grid at the beginning of off-peak hours, when many people start charging their vehicle, by setting your schedule to start a couple hours into the off-peak period."
