Description of the Related Art In an electric vehicle using a battery-powered motor as a power source, how far the remaining capacity of the battery can travel, that is, the reachable range is important for making a travel plan. Therefore, an attempt to provide such information by a vehicle-mounted navigation system is disclosed in, for example, Japanese Patent Laid-Open No. 2001-112121. In this conventional navigation system for electric vehicles, the current position is displayed on a map by a display, and it is determined whether the destination input to the navigation system can be reached or not by the map information and the remaining capacity of the battery. When it is difficult to reach the destination, it is determined that the required battery charging time is indicated to announce that it is difficult to reach the destination.

能性も考えられる。However, in the conventional navigation system for the electric vehicle described above, the battery charging time required only when it is difficult to reach the destination is used. No notification is given when the destination can be reached with the remaining capacity of the battery. Therefore, there is a possibility that the remaining capacity of the battery is almost exhausted when the vehicle reaches the destination.

を目的とする。However, unlike gas stations, the degree of popularization of battery charging equipment for electric vehicles is still low.
Therefore, if the destination is not equipped with charging facilities,
When the remaining capacity of the battery is close to zero, there is a possibility that the driver may not be able to travel to the next destination even if he tries to move next time. Therefore, in view of the above problems, it is an object of the present invention to provide a navigation system for an electric vehicle that can be alerted so that the driver can surely perform the next traveling after reaching the destination.

When it is judged that the battery cannot be charged at the destination by the judgment means and it is judged that charging at the destination is impossible, the charging equipment near the destination searched by the charging equipment search means is displayed on the display. I decided to do it. By displaying the charging equipment near the destination, you will be alerted in advance about the remaining capacity of the battery, so make an appropriate travel plan without falling into the situation where you can not travel after reaching the destination.

で充電設備を探しまわる必要もなくなる。The present embodiment is configured as described above, and allows the operator to input the destination together with the transit destination and also determine whether or not the battery 10 can be charged at the destination based on the input information, and charge the battery 10. In that case, the reachability of whether or not the vehicle can travel to the destination with the current remaining capacity of the battery is calculated and displayed on the display 50. However, when the destination does not have a charging facility, the vicinity of the destination is calculated. It is assumed that the charging equipment is displayed and selected, and whether or not the vehicle can run to the charging equipment with the remaining capacity of the battery 10 is displayed. As a result, it is possible to prevent a situation in which the vehicle 10 has reached the destination but the remaining capacity of the battery 10 is exhausted and the vehicle cannot travel next. Further, since the charging equipment near the destination can be known in advance, it is not necessary to search for the charging equipment near the destination.

択肢が広げられる。Further, instead of selecting the charging equipment in the vicinity of the destination, the operator can input the charging equipment by himself / herself. Therefore, the familiar charging equipment should be used and whether or not the charging equipment can be reached. You can also judge. Similarly, it is possible to judge whether or not the remaining capacity of the battery 10 allows the round trip from the current position to the destination by the selection operation of the operator, so that the options of the travel plan can be expanded.

必要な充電時間を明確に知ることができる。When the remaining capacity of the battery 10 allows the vehicle to travel to the destination or the charging facility, the fact that the vehicle can travel along with the route is displayed on the display 50. Alternatively, the user can understand and understand the route to the destination, the round trip route, and the like via the charging facility that is selected and input and set, and can head to the destination with confidence. On the other hand, when traveling to the destination or the charging facility is impossible due to the remaining capacity of the battery 10, the minimum charging time required to reach the destination or the charging facility is calculated and displayed on the display 50.
You can clearly know the required charging time.

できる。Further, the operator can arbitrarily set the charging time. For example, when the charging time is set shorter than the minimum charging time described above, the remaining capacity of the battery 10 at the time when the charging is completed. Is calculated and the range reachable by the remaining capacity is displayed on the display 50, so that the travel plan can be changed within the reachable range.
