Are electric scooter efficient?
For all the energy required to propel a vehicle, not all of it makes it to the wheels. Some of it is lost to friction and heat. Vehicle inefficiency can be classified into two categories of losses: road-load and energy conversion.
In an electric vehicle, chemical energy is stored in a battery. Lithium-ion batteries are used in electric scooter because of high energy density. Converting the chemical energy to free electrons (electrical energy) can be greater than 80% efficient – some energy is lost to heat in cells and other battery pack components such as current conductors and fuses. Overall, drive efficiency of an electric scooter more than 80% - almost three times more efficient than an internal combustion powered vehicle.
When you compare this to Internal Combustion Engine vehicles, chemical energy is stored as gasoline in a conventional vehicle. Combustion is used to convert the chemical energy into thermal energy. Pistons convert the thermal energy to the mechanical work that turns the wheels. The conversion process is, at best, 35% efficient. The majority of the energy stored in the gasoline is lost as heat.
