Problems solved by technology

[0013] However, if some abnormal state such as a noise signal is applied to the reset terminal of the microcomputer functioning as the power control unit, the power control unit will turn off the charge mode signal, so it is detected that the charge mode signal is turned off. In the charging control unit, there is a problem that the charging of the power storage device is terminated in the middle even when the charging of the power storage device is not completed.

Embodiment Construction

[0028] Embodiments in the case where the control device and charging control method according to the present invention are applied to a plug-in type automobile will be described below.

[0029] like figure 1 As shown, a hybrid vehicle 1 (hereinafter referred to as "plug-in hybrid vehicle") is an example of a plug-in vehicle capable of directly charging the high-voltage power storage device 50 mounted on the vehicle from a power source outside the vehicle. The source has: an engine 10 ; a first MG (Motor Generator) 11 ; and a second MG (Motor Generator) 12 .

[0030] Plug-in hybrid vehicle 1 is connected to engine 10 , first MG 11 , and second MG 12 , and power split device 13 so as to be able to run with driving force from at least one of engine 10 and second MG 12 .

[0031] The first MG11 and the second MG12 are constituted by an AC rotating electric machine, for example, a three-phase AC synchronous rotating electric machine including a U-phase coil, a V-phase coil, and a ...

Abstract

A device controls charging a battery with power supplied from a power supply located outside of a vehicle through a charge cable. The device includes a first microcomputer and a second microcomputer. The first microcomputer is configured to turn on a charge mode signal upon detecting a change in a pilot signal output through the charge cable, and to turn off the charge mode signal when a charge completion signal output from the second microcomputer is turned off. The second microcomputer is configured to charge the battery through the charge cable when the charge mode signal is turned on, and to turn off the charge completion signal when the charging is complete. When the charge completion signal is turned on at the time of the first microcomputer turning off the charge mode signal due to sudden fluctuations, the charge mode signal is turned on again.

Description

technical field [0001] The present invention relates to a control device and a charge control method for charging a power storage device mounted on a vehicle for driving a vehicle. Background technique [0002] As environmentally friendly vehicles, attention has been paid to electric vehicles, hybrid vehicles, fuel cell vehicles, and the like in recent years. These vehicles are equipped with an electric motor that generates driving force for traveling and a power storage device that stores electric power supplied to the electric motor. In a hybrid vehicle, an internal combustion engine is mounted together with an electric motor as a power source, and in a fuel cell vehicle, a fuel cell is mounted as a DC power supply for driving the vehicle. [0003] A vehicle is known in which a power storage device for driving a vehicle mounted on such a vehicle can be directly charged from a general household power supply. For example, by connecting an outlet of a commercial power suppl...
