Instead of dwelling on the scheduled charging issues with the RAV4EV, I'd like to make a suggestion to the Tesla engineers (or other EV companies) about an ideal charger control strategy.
1. To address those customers that can take advantage of off-peak hours, have the ability to program a "Do not begin charging until after x" option.
2. Keep the feature that says when the car needs to be fully charged before the next departure.
3. In order to keep peak loads down, allow the charger to only charge at the rate necessary to meet the two constraints above, rather than just charge at full power somewhere in between. For example, instead of charging the RAV4EV at 7.2kW for 3 hours and sitting idle for 3 hours (assuming a 6 hour window), why not throttle back the charge rate to 3.6kW for 6 hours instead? This would reduce peak loads on the house and on the neighborhood transformer (once everyone in the cul-de-sac has an EV
).
4. Keep "charge immediately feature" at full charge rate.
I hope that EV companies in the future incorporate feature #3 listed above.
Are there any potential problems you see with this?
Are there any other features you'd like to see that would benefit your experience?
