The present disclosure relates to systems, methods, and devices for controlling charging of vehicles, to avoid charging during charge-adverse time periods or during charge restriction events. This can advantageously reduce cost to vehicles owners, and or provide access to reward incentives. Further, power distribution entities (utility providers) advantageously have increased control over power distribution to avoid over-burdening of power distribution infrastructure. Further, systems and methods for determining or inferring whether a vehicle is connected to a charge station are described, which can be used to inform automatic restriction of vehicle charging.
