WebNov 14, 2024 · Unlike resurfacing, replacing a flywheel takes hours. A mechanic may spend near 4 to 5 hours to replace your flywheel. For example, their rate per hour is $100, that means you’ll have to spend $400 to $500 for labor cost alone. That would make overall total costs in the range of $400 to $1500, depending on the vehicle. WebFlywheel energy storage is characterized by its long lifetime (typically 20 years) [36,37]. A flywheel is a disk with a certain amount of mass that can spin to store energy in kinetic form. To prevent the influence of gravity, the disk in flywheel ESS are built in perpendicular position of the rotor.
