A device and method determines available regenerative braking energy in a route for a target vehicle. The device is in communication with a navigation unit and is configured to split the at least one route between a source and a destination into multiple segments followed by determining vehicular data of the target vehicle. The device determines available/recoverable regenerative braking energy in the at least one route for the target vehicle based on selective vehicular data of other vehicles similar to the target vehicle, which have travelled through the at least one route. The device is configured to dynamically predict the available regenerative braking energy originating from random longitudinal deceleration maneuvers for the chosen route from source location to the chosen destination location for any hybrid or electric vehicle. The device improves fuel efficiency and reduces emissions.

System, methods, and other embodiments described herein relate to adjusting a trip fare according to in-vehicle charging provided by a passenger. In one embodiment, a method includes, in response to initiating a trip in the vehicle for a passenger, accumulating the trip fare as a function of traveling a route to fulfill the trip. The method includes metering one or more charging devices to identify a metered charge produced by the passenger operating the one or more charging devices during the trip. The method includes computing a fare offset according to at least the metered charge to identify an amount by which the trip fare is to be discounted. The method includes adjusting the trip fare according to the fare offset to account for an electric charge provided to the vehicle during the trip.

A vehicle performs notification about an open/closed state of a lid member covering an interface for supplying driving energy. The vehicle includes a notification portion that performs notification when the lid member is in the open state and a connection detecting portion that detects a connection state of a driving energy supply device to the interface. In the vehicle, the notification portion suspends notification when the driving energy supply device is connected to the interface during the open state of the lid member.
