Embodiment Construction

[0046] figure 1 According to the present invention, a device 10 for route planning of an electric vehicle according to the present invention is shown. The device 10 includes an input interface 12 , a database interface 14 , an energy planning unit 16 , a charging planning unit 18 and a matching unit 20 . The device 10 can realize the matching of the pre-planned route so as to pass by the charging station that can charge the energy accumulator of the electric vehicle. In this case, the at least one adapted route is ascertained on the one hand on the basis of a predicted profile of the state of charge of the energy store (ie a prediction of the energy consumption of the electric vehicle when traveling along the route) and on the other hand on the basis of, inter alia, The charging station information including the location of the candidate charging station is carried out. By automatically and formally selecting a charging station or knowing the matched route passing through th...

Abstract

The present disclosure relates to a device (10) for route planning for an electric vehicle (26), comprising: an input interface (12) for receiving an up-to-date charge level of an energy storage (24)of the electric vehicle and a planned route (32) for the electric vehicle; a database interface (14) for receiving charging station information with locations of charging stations; an energy planningunit (16) for determining an estimated status of the charge level of the energy storage, based on the up-to-date charge level of the energy storage and the planned route; a charging planning unit (18)for selecting a charging station based on the estimated status of the charge level, the charging station information and the planned route; a matching unit (20) for determining at least one customized route (34) passing through the location of the selected charging station (40) based on the planned route.

Description

technical field [0001] The invention relates to a device, method and system for route planning of an electric vehicle and a navigator. Background technique [0002] Today, most traffic participants use route planners or navigators in order to reach their destinations. Such instruments may be implemented in a vehicle in combination with a vehicle information and entertainment system. Alternatively, there are also separately implemented devices which allow simple retrofitting, for example by being attached to the windshield of the passenger vehicle. Furthermore, the corresponding functions can also be fulfilled by a mobile phone or tablet computer with corresponding software (app). [0003] In most cases, current navigators have internal or external positioning sensors, such as GPS receivers, which allow to know and track their own position. Typically, the input of the target location is done manually by the driver, for example via keys, a touchscreen input or voice input. ...
