S54: Output the power supply station information to a display device.

In step S51, the present invention utilizes the processing unit 10 to receive the battery power information provided by the driving data unit 20 at any time.

In step S52, the processing unit 10 judges whether the trigger condition is met according to the battery power. The trigger condition can be selected from the following conditions, or each condition can be used together, as long as any one of the conditions is met , Which is regarded as conforming to:

1. Fixed power threshold: A power threshold is preset in the memory storage unit 20, for example, 25% of the battery rated power. The processing unit 10 compares the detected current battery power of the locomotive with the power threshold. When the battery power has been consumed to the power threshold (25%), it is deemed to meet the trigger conditions.

Adjacent to the preset route power supply station: the user can pre-set multiple regular riding routes, and the processing unit will determine whether the charging station is suitable among the regular riding routes specified by the user; for example, the user The set frequent riding route includes a commuting route between home and company. When the user specifies the commuting route for searching, the processing unit 10 uses the commuting route as a reference basis to determine whether there is a commuting route nearby When judging whether the power station is adjacent to the commuter route, a preset range can be used as the criterion. For example, the distance between the location of the power station and the commuter route is less than the preset range, which can be regarded as The power supply station is adjacent to the commuter route.

In step S54, according to a preferred method of the present invention, the processing unit 10 can output the searched power supply station information to a display device, for example, through the data transmission unit 60 to the user's mobile device 200 for use View the information of the power supply station on the mobile device 200; in another preferred way, the processing unit 10 outputs the searched power station information to the digital instrument panel 50 for the convenience of the user in the instrument display area 51 View power supply station information; in another preferred way, the processing unit 10 transmits the searched power station information to the user’s mobile device 200 through the data transmission unit 60, and outputs it to the digital dashboard 50.

Regarding the output format, please refer to Figure 6. Whether it is output on the mobile device 200 or displayed on the digital dashboard 50, the power supply station information is presented on a map screen, that is, the power supply station information is combined with pre-existing power supply station information. The stored map data is based on the coordinate data of the power supply station to overlay and display a power supply station mark 70 on the map. Furthermore, the processing unit 10 or the mobile device 200 automatically plans a navigation route to the power supply station according to the current location of the vehicle, and the navigation route can be displayed on the mobile device 200 or the digital dashboard. Alternatively, the searched power station information can be output as a voice message.
