1. A vehicle charger for charging a battery of a vehicle, the vehicle charger comprising:
a controller; and
a memory coupled to the controller and storing a vehicle charger setting received from a user, the vehicle charger setting at least partially determining a delay before which the controller will automatically begin charging the battery,
wherein the controller is configured to:
start a vehicle charging session of the battery according to the vehicle charger setting, wherein the vehicle charging session includes the delay before which the controller will automatically begin charging the battery,
in response to a detected level of charge of the battery being below a threshold minimum level of charge, supply, during the delay and independent of the vehicle charger setting, electric power to the battery based on the detected level of charge of the battery, and
after supplying the electric power to the battery based on the detected level of charge of the battery, resume operation of the vehicle charging session according to the vehicle charger setting.
