How many kilometers can two people go with 5 60V batteries in this electric car?

When you are ready to buy an electric car, how do you know how many kilometers the electric car can run?

There are many methods, the standard method is to passively control the output torque and speed of the driving wheel, or actively control, and measure the total current value of the motor at the same time, which can be converted.

This involves the two-dimensional relationship between vehicle speed and output torque, and involves the efficiency of the motor

It involves the design level and coordination effect of the motor controller.

In electric vehicle manufacturers, in electric vehicle motor controller manufacturers, such tests are carried out, and the professional description is a test bench, a test bench, a dynamic load bench, and a dynamometer.

It is possible to make a device similar to the annual review of motor vehicles, such as the equipment for brake testing, with two parallel wheels, the rear wheel of the electric vehicle is framed on it for dynamic testing.

If you ordinary consumers can make such equipment very neatly, as long as there is 1 in 10,000, China's economic strength, national defense strength, national quality, etc., will surpass the United States.

The questioner said: It's too complicated, I replied:

It's so-so. This is a very basic part of the Western science and technology system, and Chinese, even doctoral supervisors, are always students.

In addition, after the electric vehicle is charged, the maximum mileage is also related to the battery capacity and the charger.

This kind of active equalization charger in the real sense is used in electric cars abroad, with complex structure and high cost.

It is extremely difficult to see its traces in the domestic market and scientific research and first-class projects.

I made a simple self-use, a set took 6 months, width meters, height meters, thickness meters, all metal shell.

The other took more than 3 months, the width of the meter, the height of the meter, the thickness of the meter, the all-metal shell, with 12 current judgment and display units, 8 points of logic judgment and display function.

guowuyuan, qiaowuban, zhuren Qiu 1 aid 1 draw, what do you say?

Your question belongs to the very basic, very traditional and completely open engineering technology of the power industry for more than 100 years, such as water pumps, blowers, electric motors, fuel engines, launch vehicles, aero engines, ship propellers, various propulsion devices of ships, etc., all have similar test methods.

Connoisseurs, for low-power electric vehicles, just measure the driving torque, is to use the foot with shoes, from one side to squeeze the outer tire of the driving wheel, to produce braking torque, according to the speed of the driving wheel, according to the resistance of the foot and the speed of the driving wheel hardness and softness, that is, when the resistance increases, the degree of speed decrease, can be estimated by experience.

It's actually only 100 kilometers!
