Description

  The present invention relates to a mobile charging device and a mobile charging method for charging a device that moves using electric power as power.

  An electric vehicle obtains electric power necessary for traveling from an installed battery, but the battery must be connected and charged from a power outlet before traveling. This charging method is generally performed by using a power cable from a household 100V outlet. There is also a method of charging in a non-contact state by bringing a coil to be charged (secondary coil) connected to a battery to be charged close to a charging coil (primary coil) that supplies power.

In the inductive charging method in which electric power is supplied to a battery of an electric vehicle by electromagnetic induction from a charging station having a non-contact connector as a conventional technique, the charging time of the battery is shortened and generated by adjusting the frequency of the supplied power. There is a charging method for reducing power loss (see, for example, Patent Document 1).

This requesting method may be a method through a third party such as a company that owns the mobile charging vehicle 1, a communication using the vehicle-to-vehicle communication unit 12, or a method of signaling at a hazard. After approaching the to-be-charged vehicle 2, the control unit 11 obtains distance measurement data between the to-be-charged vehicle 2 and the own vehicle (mobile charging vehicle 1) by the distance measuring sensor 13 (S 102). It is determined whether or not the charging vehicle 2 is in a chargeable state and within the chargeable range (S103). If charging is not possible, the control unit 11 gives an instruction to the driver or a driving system (not shown) to move the mobile charging vehicle 1 until the charging is possible, and controls the inter-vehicle distance (S112). The process of S103 is repeated.

  When the chargeable range is reached, the control unit 11 controls the distance between the mobile charging vehicle 1 and the to-be-charged vehicle 2 to be a constant chargeable distance by the distance measuring sensor 13 and the inter-vehicle distance maintaining unit 14. It performs (S104, distance maintenance step). After maintaining the chargeable distance, the control unit 11 performs charging communication to the vehicle-to-vehicle communication unit 12B of the to-be-charged vehicle 2 through the vehicle-to-vehicle communication unit 12A (S105, charging step), and determines whether or not charging has been successfully performed. (S106). In addition, if the to-be-charged vehicle 2 cannot charge normally here, it will become impossible to charge and this flow will be complete | finished (S113). When the charging can be normally performed, the control unit 11 starts charging the electric power from the charging coil 17A to the charging coil 17B of the to-be-charged vehicle 2 by the large capacity battery 15 and the inverter 16 (S107, S108, charging step, non-charging). Contact charging step).

  After the start of charging, the control unit 11 determines whether or not the charging is completed. If the charging is insufficient (S109, NO), the process of S108 is continued. In the above-described determination method, the control unit 11 counts the time from the start of charging (S107) and ends after a certain time has elapsed.

Also, the operation in start S101 is similar to the operation in S101 in the flow of FIG.

  First, after the mobile charging vehicle 3 approaches the vehicle to be charged 4 within the communication range of the vehicle-to-vehicle communication unit 34, the control unit 31 starts communication with the vehicle-to-vehicle communication unit 34B of the vehicle 4 to be charged by the vehicle-to-vehicle communication unit 34A (S201). ). After the start of communication, the control unit 31 receives performance specification data such as destination information, remaining battery data, and fuel consumption performance of the to-be-charged vehicle set by the car navigation system 41 of the to-be-charged vehicle 4 through the inter-vehicle communication 34A. (S202, first receiving step, second receiving step, third receiving step).

Here, the value of n can be set arbitrarily. After the search, the control unit 31 stores the information related to the searched charging station as a search list in a storage area (not shown). Next, the control unit 31 deletes the charging station in the reverse direction from the own vehicle position and the destination direction from the search list (S205, exclusion step). After the deletion, the control unit 31 calculates the distance (distance) to each searched charging station (S206), calculates the nearest charging station from the calculation result (the unit of the calculation result is km) (S207), and is necessary. The amount of charge (the minimum amount of charge required to the charging station) is calculated (S208, calculation step). In addition, in the calculation of the distance to the searched charging station, when the searched charging station is one, the required charge amount is calculated immediately after calculating the distance to the charging station. Moreover, the calculation formula of required charge amount (C [Kwh]) is as follows.

C = S × (p × LR) [Kwh]
S is a margin coefficient, p is fuel consumption [Kwh / km], L is a distance to the charging station [km], and R is a remaining battery capacity [Kwh].

After transmitting the charging station data, the control unit 31 performs a charging process (S210, charging step, instruction step), and this flow ends (S211). As described above, the operation of the mobile charging vehicle 3 in the charging process S210 is the same as that in S102 to S110 in the first embodiment, and thus the description thereof is omitted.

  According to the present embodiment, the inter-vehicle communication unit 34, the positioning unit 32, the charging station map 33, and the control unit 31 that controls them acquire the vehicle position, search for nearby charging stations, Based on the destination information of the charging vehicle 4, the battery remaining amount information, and the specification data, only the necessary minimum charging to the nearest charging station can be performed, and the charging time can be shortened.
