The Toyota Mirai is a fuel cell electric vehicle (FCEV) that runs on hydrogen. It does not have a traditional battery like electric vehicles. Instead, the Mirai uses a fuel cell stack to convert hydrogen into electricity, which powers the vehicle’s electric motor. The only by-product of this process is water.
Therefore, the Toyota Mirai does not have a conventional battery size like other electric vehicles. Instead, it has a fuel cell stack that generates electricity from hydrogen.

Why did Toyota Mirai fail?
Chief technology officer Hiroki Nakajima told the Japan Mobility Show in Tokyo (formerly the Tokyo Motor Show) that that the Mirai has never taken off due to the small numbers of H2 fuelling stations — a problem that is less significant for trucks. “We have tried Mirai but not been successful,” said Nakajima.
How long does a hydrogen fuel cell battery last?
approximately 150,000-200,000 miles
For example, many automakers of passenger cars aim for a fuel cell stack lifespan of at least 5,000 hours or approximately 150,000-200,000 miles. In the heavy-duty category, many bus fuel cell stacks (power plant) have reached lifetimes of 20,000 hours and more, with a goal of 30,000 hours by 2030.
What is the voltage of the Mirai battery?
approximately 244.8 Volt
Numerous safeguards have been designed into the MIRAI to help ensure the high voltage, approximately 244.8 Volt, Nickel Metal Hydride (NiMH) Fuel Cell Vehicle (EV) battery assembly is kept safe and secure in an accident.
What kind of maintenance does a Mirai need?
The Mirai has regular 5,000-mile maintenance intervals just like a traditional vehicle; however, since there is no oil to change, most maintenance intervals are composed of inspections to help ensure your Mirai is staying in top condition.
Is Toyota discontinuing the Mirai?
Verdict The future of hydrogen fuel cell vehicles is still in development, and the Mirai isn’t giving up.
What is the capacity of the hydrogen car battery?
The extra amount of electricity store in the battery pack. In the fuel cell electric vehicle, the use of battery is lithium-ion battery pack. The capacity of battery used in fuel cell electric vehicles are near 1.5 to 2 kwh.
Do hydrogen cars need big batteries?
They don’t need large batteries as the fuel cell works to turn hydrogen into electricity to drive the motors. A recent study found a hydrogen car emits around 120g/km of CO2 over its lifetime, but this can be brought down significantly to around 60g/km when hydrogen is produced using renewable energy.
Is Mirai bigger than Camry?
Measuring 4975mm long, 1885mm wide, 1470mm tall and with a 2920mm wheelbase, the second-generation Mirai is comparable in size to a mid-size sedan like the Camry and Mazda6.
What is the life expectancy of a Toyota Mirai?
How hydrogen vehicle engines work is complex but fascinating, and the Toyota Mirai is at the forefront of the technology. So, how long can you expect this system to last? According to the H2 California Fuel Cell Partnership, the fuel cells should reach between 150,000 and 200,000 miles.
Does the Toyota Mirai use lithium batteries?
Electricity generated by the Mirai’s fuel cell and the regenerative braking system is stored in a lithium-ion battery. Pressing the accelerator pedal yields immediate flow of electric power from the fuel cell and/or battery to the rear-mounted AC synchronous electric motor, which drives the rear wheels.
