A driving cycle is a series of data points representing the speed of a vehicle versus time. Driving cycles are produced by different countries and organizations to assess the performance of vehicles in various ways, for example, fuel consumption, electric vehicle autonomy and polluting emissions.

The car may only have one gear ratio, and the motor simply runs in the opposite direction to make the car go in reverse. Some electric cars with DC motors also have this feature, using an electrical switch to reverse the direction of the motor, but others run the motor in the same direction all the time and use a traditional manual or automatic ...
Using a PMU, it is simple to detect abnormal waveform shapes. A waveform shape described mathematically is called a phasor.. A phasor measurement unit (PMU) is a device used to estimate the magnitude and phase angle of an electrical phasor quantity (such as voltage or current) in the electricity grid using a common time source for synchronization.
A controller area network (CAN) is a vehicle bus standard designed to enable efficient communication primarily between electronic control units (ECUs). Originally developed to reduce the complexity and cost of electrical wiring in automobiles through multiplexing, the CAN bus protocol has since been adopted in various other contexts.
The term "electric car" typically refers specifically to battery electric vehicles (BEVs) or all-electric cars, a type of electric vehicle (EV) that has an onboard rechargeable battery pack that can be plugged in and charged from the electric grid, and the electricity stored on the vehicle is the only energy source that provide propulsion for ...
The RBS is a key mechanism for electric vehicles to obtain braking energy. This technology seriously affects the economy, emissions, safety and other functions of electric vehicles. By improving the RBS, the kinetic energy recovery rate of the vehicle can be significantly increased, and the driving stability of the vehicle can be improved. [61]

Mild hybrid electric vehicle (MHEV, BAHV) Exclusively uses petroleum or other fuel, but has electric battery to consume less. Plug-in hybrid vehicle (PHEV) Uses mixture of petroleum or other fuel and electricity from power grid. All-electric vehicle (BEV, AEV) Exclusively uses electricity from power grid. Fuel cell vehicle (FCV, FCEV)
