Mechanical energy storage systems take advantage of kinetic or gravitational forces to store inputted energy. While the physics of mechanical systems are often quite simple (e.g. spin a flywheel or lift weights up a hill), the technologies that enable the efficient and effective use of these forces are particularly advanced.
Unlike other hybrid energy systems that focus on energy management itself, our control scheme prioritizes the actual operational performance of the motor. In the absence of control action in an open-loop system, the fluctuation in the charging and discharging rates of the supercapacitor is determined by its inherent characteristics.

The mechanical energy consumption, which is calculated at the motor shaft, solely consists of the energy needed to compensate for the gearbox losses. At the resonance frequency ω p, there is no torque and, since gearbox losses are modeled to be proportional to torque, no power consumption.
Within a motor-driven gearbox, the motor instigates the power, while the gearbox modulates output velocity and torque. The gearbox is an intricate maze of gears orchestrated in a unique pattern.
A gear motor is a mechanical device consisting of an electric motor and a gearbox that has lower RPM, and higher torque. DC motor is a type of electric motor that converts electrical energy into mechanical motion directly, without an integrated gearbox. Gear motors offer torque and speed control, while DC motors primarily provide

The most power-demanding cycle was WLTC, while NEDC was less power demanding. However, the specific driving energy per kilometer was very similar for NEDC and FTP-75, as it respectively accounted to 0.118/0.116 kWh/km and 0.117/0.115 kWh/km. WLTC led to a higher specific consumption of 0.127/0.124 kWh/km.
