A)  Battery storage. Use as the example Tesla model S
  • Powertrain
  • Model S is a rear wheel drive electric vehicle. The liquid-cooled powertrain includes the battery, motor, drive inverter, and gear box.
  • 60 kWh microprocessor controlled, lithium-ion battery
  • Three phase, four pole AC induction motor with copper rotor
  • Drive inverter with variable frequency drive and regenerative braking system
  • Single speed fixed gear with 9.73:1 reduction ratio
Electric motor 310 kW (416 bhp), 600 N·m (443 ft·lb), Three-phase AC induction motor
Transmission 1-speed fixed gear (9.73:1)
Battery 60 or 85 kWh lithium ion[4]
Electric range
  • 85 kWh
    265 mi (426 km) (EPA)
    310 mi (500 km) (NEDC)
  • 60 kWh
    208 mi (335 km) (EPA)
    233 mi (375 km) (NEDC)
Plug-in charging
  • 11 kW 85-265 V onboard charger for 1ϕ 40 A or 3ϕ 16 A [5] on IEC Type 2 inlet[6]
  • Optional “Twin Charger” for 22 kW for 1ϕ 80 A or 3ϕ 32 A[5]
  • Optional Supercharger for 120 kW DC offboard charging, adapters for domestic AC sockets (110-240V)
60 kWh will go 208 miles = 3.5 miles/kWh
cost of travelling 1 mile = cost of 1kWh/3.5
from the warrantee, the batteries are warranteed  for 120,000 miles/208 miles = 570 cycles
If the cost of the battery is $500/kWh, the cost per cycle= $0.87per kWh amortisation.
We have to add the cost of electricity assume $0.15/kWh, total cost per mile = ${0.87+0.15}/3.5 = $0.29/mile
B)   Toyota  mirai FCV, high pressure hydrogen fuel
Electric motor fuel cell-powered 113 kW (152 hp) 335 N·m (247 lbf·ft)[1]
Battery 1.6 kWh Nickel-metal hydride[2][3]
Range 480 km (300 mi) (Toyota)[4]

Fuel cell system with an output power density of 3.0 kW/L

The FCV range is expected to be approximately 700 km (430 mi) under Japan’s JC08 test cycle.[15]
The exhaust  H2O or water volume is 240 mL per 4 km running.[35]
the stack’s world-leading power output density of 3.1 kW/L
The tanks store hydrogen 70 MPa (10,000 psi). The tanks have a combined weight 87.5 kg (193 lb).[1][34]
The electric traction motor delivers 113 kilowatts (152 hp) and 335 N·m (247 lbf·ft) of torque. The Mirai has a 245V (1.6 kWhsealed nickel-metal hydride (NiMH) traction rechargeable battery pack

The front tank holds 60.0 liters, the rear tank, 62.4 liters. Total hydrogen storage mass is about 5 kg.


They estimate $50 for a full tank of H2 and 300 miles range. Compare this with a Prius, which is cheaper, can refuel at any gas station, has a range of 595 miles, and the gasoline would cost $18 to go 300 miles. With competition like that, the FCV could be a difficult sell, even in Japan.

Using the data above.
Mirai has 300 miles range for the 5kg of H. to compare to Tesla, we use 120,000 miles warrantee
The 5kg H fuel costs estimated by toyota, $50 or $10/kg. to go one mile has a fuel cost of $50/300 = $0.17/mile
We have to amortize the cost of high pressure cylinder + the cost of FC stack over 120,000 miles.
We do not have numbers from Toyota, but from NREL the estimate is $2400, or $2400/120,000 miles, = $0.02/mile
total cost of travel $0.17 +$0.02 = $0.19/mile
