An FCV includes: a driving device that generates traveling power by using at least one of electric power output from an FC system and electric power output from a battery; and a display device that presents a first indicator and a second indicator, the first indicator indicating a remaining amount of electric power to be output from the FC system, the second indicator indicating a remaining amount of electric power to be output from the battery. An amount of electric power that can be output from the FC system when the hydrogen tank is full is larger than an amount of electric power that can be output from the battery when the battery is fully charged. A presentation area of the first indicator is larger than a presentation area of the second indicator.

A vehicle control method and device. The vehicle control method comprises the steps of generating a first control instruction and a second control instruction when a vehicle is in a parking state, so that a fuel cell control unit (FCU) is controlled to perform charging control on a battery management system (BMS) through the first control instruction, a vehicle control unit (VCU) is controlled to perform power-off control on a target component through the second control instruction, and the target component is a non-essential operation component when the vehicle is charged in a parking state; and generating a third control instruction when the vehicle is in a normal operating state, so that the VCU controls the BMS according to the third control instruction. According to the method, under different vehicle states of the BMS, the control instructions are sourced from different control units; after the vehicle enters the parking charging mode, the non-essential components are enabled to stop working to lower a parasitic load, thereby improving the charging efficiency of the system.
