A cruising range information device of an electric vehicle
Document Type and Number:
Japanese Patent JP6025146
Kind Code:
B2
Abstract:
Provided is a cruising range notification device for an electric vehicle capable of notifying a driver, or the like, whether it is possible to return to a stored point with the current amount of remaining battery power in a case where traveling is performed so as to return along the same route. An electric vehicle is provided with a cruising range notification device (1), a navigation device (6), and regenerative energy devices (3, 4) capable of recovering energy on a downward slope. The cruising range notification device (1) is provided with a remaining battery power detection means for detecting the remaining power of a battery (2) at a prescribed point; a return impossibility determination means for determining that further progress will result in being unable to reach the prescribed point on a return trip by taking into consideration an estimated necessary amount, which is obtained by adding an estimated required power for flat road travel that is estimated as being necessary for a return trip along the same route over a flat road to the absolute value of the recovered energy recovered from gradient resistance during the outbound trip with the sign reversed, or an equivalent amount, and the remaining power of the battery (2); and notification means (1b, 1c) for reporting information relating to the impossibility of returning when it has been determined that returning is impossible.
