How many horsepower is the electric 800W motor?
The performance of a car is inseparable from the strength of its power. The basic unit of car power is horsepower (horse). The basic car of our family car is 80-150 horses, and the maximum speed is between 180-240km/h. Why is the standard for electric vehicle power measurement watts (W) instead of horses? Converted to the number of horses, how many horsepower is 800W electric car, how much power can it provide?
As an ancient unit, horsepower originated from the British watt. In the metric system, 1 horsepower is equal to the work of raising a 75-kilogram object by one meter per second. Note that this is a metric horsepower. 1 horsepower = 75kg · m / s = 735W, that is, the 800W motor electric car can output 1.1 horsepower.
The electric motor power that we usually use most is 400W-1000W, which is 0.5PS-1.5PS. The difference is very small. If we use horsepower to calculate, the electric vehicle power classification will be very simple and rough. And horsepower as an ancient power unit, in addition to cars and air conditioners are still in use, the rest of the electrical appliances do not use the unit to calculate energy consumption, but directly with watts!
So how much power does the 800W motor equivalent to 1 horsepower provide?
The electric vehicle with 800W motor, plus the weight of the battery and the body, is generally about 60 kg, plus 150 kg of people, the total weight is about 135 kg, 800W motor is equipped with 60V20Ah battery, under normal circumstances, 800W The maximum speed can reach 50km/h. If you drive at a speed of 20km/h and load 135kg, you can climb a 15-meter steep slope of 100m.
After the new national standard, electric vehicles began to be divided into three categories: electric bicycles, electric motorcycles and portable electric motorcycles. The main standard is motor power and speed. The motor power is less than or equal to 400W, and the speed is not more than 25km/h. The car belongs to the standard electric bicycle, and the motor power is between 400W-800W, the cutting speed is lower than 50km/h for the portable electric motor, and the motor power is more than 800W, it is the electric motorcycle product, the current mainstream electric motorcycle product The power is between 1500W-2000W, which is between 2-2.5 horses.
In addition, most of the domestic super-standard cars, power is mostly between 800-1000W, the highest Mavericks N-GT up to 3000W about 4.5 horsepower, such a powerful power, has far met our basic load requirements, in daily life The 400W-800W power motor is enough.
