Embodiment Construction

[0043] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application or uses of the invention. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.

[0044] In one embodiment, the driver enters parameters for a charging plan stored in the on-board processor. The driver enters the parameters via a device connected to the vehicle communication system or via the vehicle interface. Using these parameters, the processor establishes a charging schedule and determines whether the vehicle battery can be recharged according to this schedule. If the vehicle battery cannot be recharged according to this schedule, the driver is alerted. Prior to the scheduled start time, the processor periodically receives signals from on-board sensors to determine whether the vehicle is connected to an ...

Abstract

Methods and systems are provided to charge a vehicle battery from an external power source. The system includes a sensor configured to detect an electrical current received from the external power source and a processor configured to determine a charging schedule related to charging the vehicle battery. The processor is also configured to determine a variation from the charging schedule based on the electrical current and to direct transmissions of messages based on the electrical current detected by the sensor. The system includes a remote electronic device configured to receive the messages and to alert a driver of the plug-in vehicle based on the messages.

Description

technical field [0001] This document relates generally to off-board charging vehicles, such as electric vehicles and hybrid electric vehicles, and more particularly to systems and methods for alerting drivers of off-board charging problems. Background technique [0002] Off-charging electric vehicles include electric vehicles, hybrid electric vehicles, and a wider range of vehicles that typically have a vehicle battery that can be recharged from a wall outlet or other external source. Vehicle batteries are used to power the electric motors that propel the vehicle. Batteries generally require periodic recharging. Recharging is usually done with no one present, so if there is a problem while recharging, the driver won't find out until it's time to use the car. However, by then, the uncharged vehicle is not ready for use. Recharging the plugs in the vehicle, a form of refueling, can take hours and is often done when the vehicle is left unattended. Unattended charging also a...
