A typical motor will be in the 20,000-watt to 30,000-watt range. A typical controller will be in the 40,000-watt to 60,000-watt range (for example, a 96-volt controller will deliver a maximum of 400 or 600 amps).

It is the output power of the motor. So a 2 hp motor is capable of delivering a power output of 2 x 746 watts.

The 300-volt, 50-kilowatt controller for this electric car is the box marked "U.S. Electricar." In this car, the controller takes in 300 volts DC from the battery pack. It converts it into a maximum of 240 volts AC, three-phase, to send to the motor.

Electric cars vs petrol cars With the average UK electricity price sitting at around 14p per kWh and if you assume an electric car will travel 3.5 miles per kWh on average, to travel 100 miles would cost around £4 or 4p per mile.

In an electric motor, the mechanical power is defined as the speed times the torque. Mechanical power is typically defined as kilowatts (kW) or horsepower (hp) with one watt equaling one joule per second or one Newton-Meter per second. Horsepower is the work done per unit of time.

Research by the European Energy Agency found that, even with electricity generation, the carbon emissions of an electric car are around 17 – 30% lower than driving a petrol or diesel car. The emissions from electricity generation are also dramatically improved when low carbon electricity is used.

An average electric car consumes approximately 0,20 kWh/km. On a daily basis, this makes approximately 47 kilometers of driving.

The rule of thumb number used for energy required for EVs in normal driving is 25 KWH for 100 miles. Large cars will need more and small cars will need less.

Electric vehicles are all about low running costs and emissions and win out against hybrids on both counts. Pure electric vehicles can have a range of up to 325 miles, with an average of 194 miles on a single charge.

Modern electric cars usually have batteries with a capacity of 24 to 100 kWh – kilo-Watt-hours. That's a measurement of the energy stored in the batteries. One kWh means one thousand watts for one hour. So a 24 kWh battery holds enough energy to supply 24,000 Watts for one hour.

Roped overhead traction elevators power usages is approximately correctly and answered by Anonymous below. Typical motor sizes are 5 to 50 horsepower. Hydraulic elevators, however, lift both the empty car and the load in the elevator (with no counterweight), so they use about 3 times a much power.

Yes there is pretty much a fossil fuel backbone to all of this for now. However a typical car engine is about 25% efficient. An electric motor is typically greater than 90%. So overall you will get less emissions with the EV, even in areas with heavy coal.

Electric cars are capable of being quicker than gas-powered cars, but EVs aren't yet capable of going faster. ... Furthermore, an electric car's motor eliminates the need for a traditional transmission in many modern designs. The power goes straight to the wheels for instant acceleration, making EVs quicker on the start.

Under normal circumstances, a cigarette lighter can be expected to draw roughly 10 amps, and cigarette lighter circuits usually have 10 or 15 amp fuses. This allows you to plug in phone chargers and other devices that draw less than 10 or 15 amps, depending on the fuse in your specific vehicle.

Mild Hybrid cars only use their electric motors to support the engine during acceleration and cruising – the electric motor cannot power the car on its own. In a full or self-charging Toyota Hybrid, you can enjoy pure electric power for up to 50% of your city journeys and when cruising at speeds up to 50 km/h.

Whereas conventional vehicles burn fuel in an internal combustion engine, battery-powered electric vehicles don't have an engine. Instead, they use energy stored in batteries to power one or more electric motors.
