Embodiment 1

[0035] figure 1 The structure of the electric power device (charger) 100 for a vehicle according to the embodiment is shown. The electric power device 100 for a vehicle is configured to supply charging power to a storage battery 21 equipped with an electric vehicle 101 such as an electric vehicle (EV) or a plug-in hybrid electric vehicle (PHEV), thereby charging the storage battery 21 .

[0036] The electric power device 100 for a vehicle includes a power converter 1 , an electric cable 2 and a connector 3 .

[0037] The power converter 1 includes a power conversion circuit 1a, a control unit 1b, an operation unit 1c, a display unit 1d, and an audio output unit 1e. The power conversion circuit 1a is configured to convert commercial power as a power source into DC (direct current) power to output the DC power as charging power according to the operation control of the control section 1b. An output (terminal) of the power conversion circuit 1 a is connected to one end of an e...

Deformed example 1

[0055] In order to discharge the voltage between the connecting pins of the connector 3 before the locked state of the lock portion 3b is released, as Figure 7 As shown, the power converter 1A may be provided with a discharge circuit 11 . Optionally, the connection pins of the connector 3 detached from the socket 22 may be hidden to prohibit the user from directly touching the connection pins. Therefore, the electric power device 100 for a vehicle can prevent the user from receiving an electric shock by accidentally touching the connection pin.

Deformed example 2

[0057] Such as Figure 8 As shown, a switch 3c is provided inside the connector 3B, and is configured to block the supply path of the charging power when the locked state of the lock portion 3b is released. The control section 1b may be configured to control ON and OFF of the shutter 3c, or configured to control ON and OFF of the shutter 3c according to the operation of the lock section 3b. Therefore, the electric power device 100 for a vehicle can prevent the user from receiving an electric shock by touching the connection pin of the connector 3 after the locked state of the lock portion 3b is released. It is also possible to prevent sparks from occurring in the event of disconnection of the connector 3 .

Abstract

A vehicle power unit (100) charges a storage battery (21) by supplying charging power from a power conversion circuit (1a) via a connector (3) connected to an inlet (22) of an electric vehicle (101). A stress detector (4) detects the force applied to a junction portion (5) according to the tensile strength of an electric cable (2). When the detected force is smaller than a threshold (K1), a control unit (1b) initiates the output of charging power from the power conversion circuit (1a). When the force detected during the output of the charging power from the power conversion circuit (1a) is equal to or greater than the threshold (K1), the control unit issues a warning through a display unit (1d) and a sound output unit (1e). When the force detected during the output of the charging power from the power conversion circuit (1a) is equal to or greater than a threshold (K2) (> K1), the control unit suspends the output of the charging power from the power conversion circuit (1a).

Description

technical field [0001] The present invention relates generally to a power device for a vehicle, and more particularly to a power device for a vehicle configured to control charging of a storage battery of an electric vehicle. Background technique [0002] In recent years, environmentally friendly electric vehicles with less toxic exhaust gas have been introduced into the market, thereby popularizing electric power devices for vehicles capable of charging and discharging batteries of electric vehicles. Examples of electric vehicles include electric vehicles (EVs), plug-in hybrid vehicles (PHEVs), and the like. [0003] A vehicle electric device configured to charge an electric vehicle has a power converter configured to output charging power for charging a storage battery. The output of the power converter is connected to one end of the charging cable. The other end of the charging cable is connected to a connector that is removably connected to an outlet equipped with the ...
