no. 1 approach
[0018] figure 1 It is a diagram showing an example of the configuration of an EV bus included in the charging system according to the first embodiment. The charging system related to this embodiment includes an EV (Electric Vehicle) bus 1 and a charging device 2 (see figure 2 ). like figure 1 As shown, an EV bus 1 (an example of a vehicle) has a power storage function unit 101 , an on-vehicle electrical component 102 , a power receiving port 103 , a charging control unit 104 , an EV bus-side communication unit 105 , and a short-distance communication unit 106 .
[0019] The power storage function unit 101 is constituted by a storage battery or the like. The in-vehicle electrical component 102 drives the EV bus 1 with the electric power discharged from the power storage functional unit 101 . Power receiving port 103 is an example of a power receiving unit provided to be able to receive electric power supplied from charging device 2 . The charging control unit 104 charges ...
no. 2 approach
[0048] This embodiment is an example in which when the temperature of the supply part exceeds the first temperature, the power supply to the EV bus is stopped, and after the power supply to the EV bus is stopped, when the temperature of the supply part becomes When the second temperature lower than the first temperature is equal to or lower, the electric power supply to the EV bus is permitted. In the following description, description of the same configuration as that of the first embodiment is omitted.
[0049] Figure 4 It is a diagram showing an example of the configuration of the charging device of the charging system according to the second embodiment. like Figure 4 As shown, in this embodiment, the charging device 400 has a temperature detection unit 401 and a charging state display unit 402 . The temperature detection unit 401 detects the temperature of the supply unit 201 . In the present embodiment, a plurality of temperature detection units 401 are provided at ...
no. 3 approach
[0054] The present embodiment is an example in which, when an abnormality in the charging device is detected, the EV bus-side communication unit of the EV bus transmits a reset signal instructing initialization of the charging device to the charging device. In the following description, the description of the same parts as those of the first and second embodiments will be omitted.
[0055] The EV bus 1 detects an abnormality of the charging device 2 such as temporary disconnection of communication with the charging device 2 or charging by the charging device 2 overtime, and stops charging of the EV bus 1 by the charging device 2 . In addition, when an abnormality of the charging device 2 is detected, the EV bus 1 notifies the crew of the EV bus 1 of the charging by displaying information indicating the abnormality of the charging device 2 on a display unit or the like included in the EV bus 1 . An abnormality of the device 2 or an occurrence record of the abnormality of the ch...
