Method for identifying operating mode of charging/supplying system between vehicle and exterior, and system for identifying operating mode of the system by the identifying method

Abstract

An operating mode of a charging / supplying system in which a vehicle is connected with a first external device or a second external device via a connecting portion used in common in a charging mode in which an electric storage device installed on the vehicle is charged with electric power from the first external device and a supplying mode in which electric power is supplied from the vehicle to the second external device, and which is operable in a selected one of the charging mode and the supplying mode, is identified. More specifically, a plurality of detection values are detected from at least one electric connection channel provided between the vehicle and the first external device or the second external device via the connecting portion, and it is determined whether the operating mode of the charging / supplying system is the charging mode or the supplying mode, based on a combination of the plurality of detection values.

Description

technical field [0001] The present invention relates to an identification method for identifying an operation mode of a charging / power supply system operable in a mode selected from a charging mode and a power supply mode at a shared connection (for example, a vehicle Inlet) is used in the charging mode and the power supply mode in which the power storage device mounted on the vehicle is powered by the power supplied to the power storage device from the external power supply device as the first external device For charging, in the power supply mode, electric power is supplied from the vehicle to an external device to be powered as a second external device. The invention also relates to an identification system for identifying the operating mode of the charging / supply system by the same method. Background technique [0002] An electric vehicle is mounted with an electric storage device (for example, a secondary battery or a capacitor), and is adapted to travel using a drivin...

Problems solved by technology

[0012] However, when it is determined whether the operation mode to be established is the charging mode or the power supply mode based only on the specific control signal as described above, the specific control signal, for example, the signal transmitting the control signal is not correctly detected for some reason. Disconnected channels, failure or malfunction of the detection mechanism used to detect the control signal, or increased contact resistance due to poor contact or age-related degradation between the connection (eg, inlet) and the connector may erroneously Determine the operating mode

[0013] If the operation mode is wrongly determined, there may be problems such as failure to charge a power storage device mounted on the vehicle using power from an external power supply device, or failure to supply power from the vehicle to an external power supply device

In other cases, the charging of the power storage device using the external power supply device and the supply of power from the vehicle to the external powered device may be performed simultaneously, which may cause an electrical short circuit between the vehicle and the external power supply device, causing problems such as external power supply device and installation Disconnection, burnout, etc. of the power storage device and power generation device on the vehicle
