Problems solved by technology

[0003] In an FCV including an FC and a power storage device such as a battery as described above, if the output of the FC and the output of the power storage device (or state of charge (SOC: State Of Charge)) are controlled incoherently, the output of the FC and the The system output obtained by adding the outputs of the power storage devices is limited, and thus the driving performance may be reduced.

Embodiment Construction

[0027] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In addition, the same code|symbol is attached|subjected to the same part or a corresponding part in a figure, and the description is not repeated.

[0028] figure 1 is a diagram showing the overall configuration of FCV1 according to the embodiment of the present disclosure. refer to figure 1 FCV1 includes a motor generator (hereinafter referred to as “MG (Motor Generator)”) 10 , an inverter 12 , an FC system 20 , a hydrogen tank 28 , a supply valve 30 , an air filter (air filter) 32 , and a compressor 34 .

[0029] MG10 is an AC rotating electrical machine, for example, a three-phase AC synchronous motor in which a permanent magnet is embedded in a rotor. MG 10 is driven by inverter 12 to generate rotational driving force. The driving force generated by MG 10 is transmitted to drive wheels (not shown). During braking of FCV1, etc., MG10 operates as a gener...

Abstract

The invention relates to a fuel cell vehicle. An FCV (1) includes an FC system(20) and a battery(40). The FC system (20) includes an FC stack (22)and a boost converter (24) that adjusts output from the FC stack(24). An FDC-ECU(60) controls output from the FC system (20) such that output from the battery (40)does not exceed an output upper limit of the battery(40). The output upper limit of the battery (40)is set to lower with lowering in SOC when the SOC becomes lower than a threshold value. A target SOC is higher than the threshold value.

Description

technical field [0001] The present disclosure relates to fuel cell vehicles. Background technique [0002] International Publication No. 2011 / 004493 discloses a fuel cell vehicle equipped with a fuel cell (hereinafter, the fuel cell is referred to as "FC (Fuel Cell)", and the fuel cell vehicle is referred to as "FCV (Fuel Cell Vehicle)". ). This FCV has an FC stack and batteries. The battery functions as a storage source of surplus electric power, a storage source of regenerative energy during regenerative braking, and an energy buffer during load fluctuations accompanying acceleration or deceleration of the vehicle. [0003] In an FCV including an FC and a power storage device such as a battery as described above, if the output of the FC and the output of the power storage device (or state of charge (SOC: State Of Charge)) are controlled incoherently, the output of the FC and the The system output obtained by adding the outputs of the power storage devices is limited, th...
