1. A method for controlling charging of a battery of a vehicle by a power source external to the vehicle, the method comprising:
receiving, by a control unit, an indication of a minimum charge threshold for the battery;
receiving, by the control unit, an indication of a charge-restriction event, the charge-restriction event being a designated period of time to solicit reduction in power usage;
determining, by the control unit, whether a charge level of the battery is above the minimum charge threshold before an end of the charge-restriction event;
if the charge level is below the minimum charge threshold, enabling charging of the battery at a first charge rate during the charge-restriction event;
if the charge level is above the minimum charge threshold, restricting charging of the battery to a second charge rate less than the first charge rate during the charge-restriction event; and
enabling charging of the battery at the first charge rate outside of the charge-restriction event, regardless of whether the charge level is above the minimum charge threshold.
