1. A system for controlling charging of a battery of a vehicle by a power source external to the vehicle, the system comprising:
a control unit; and
a communication interface,
wherein the system is operable to:
receive an indication of a minimum charge threshold for the battery, the minimum charge threshold being less than a full charge of the battery;
receive an indication of a charge-restriction event from a device remote from the control unit, the charge-restriction event being a designated period of time to solicit reduction in power usage;
determine 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, enable charging of the battery at a first charge rate during the charge-restriction event;
if the charge level is above the minimum charge threshold, restrict charging of the battery to a second charge rate less than the first charge rate during the charge-restriction event; and
transmit, via the communication interface to the device remote from the control unit, an indication of whether charging of the battery is enabled at the first charge rate or restricted to the second charge rate for the charge-restriction event.
