What is the maximum speed of an electric car with a 72v battery and a 1000w motor, and how many kilo

The 72V battery is not identifiedBattery capacity, 1000W motor maximum speed 50km h, 20ah up to 60km, large capacity to run far.

Theoretically, the full conversion of this power into a speed of about 50 km/h; But the Standardization Administration of the People's Republic of China.

The "General Technical Conditions for Electric Motorcycles and Electric Mopeds" has been promulgated, which stipulates that the speed of electric vehicles produced by manufacturers is not allowed to exceed 20 kilometers per hour.

In practice, the speed limit standard adopted by manufacturers is generally higher than 20 kilometers per hour, and the speed of electric vehicles on the market is probably below 40 kilometers per hour and above 20 kilometers per hour. If you use a 72V 40Ah battery, you can theoretically run 100 kilometers on a flat road; If you use a 72v 20ah battery, you can run 50 kilometers on a single bike on a flat road.

Generally, it is equipped with various famous brands of electric bicycles with 36 volt 12 ampere-hour high-quality batteries.

The nominal mileage of the driving distance is about 45-60 kilometers, and the nominal mileage of some manufacturers will rise to 70-80 kilometers, which is falsely advertised.

suspicion. Because reaching this nominal value means that the efficiency of its motor is nearly 40% higher than that of the motor adopted by the famous brand factory.

If the efficiency of the motor produced by a famous brand factory is 75% in the working state described above, the motor efficiency of the manufacturer with a nominal 70-80 km has reached more than 100%, which is obviously impossible, which is especially reminded of the attention of consumers.

V is the voltage value of the battery, not the capacity value of the battery, and it is impossible to know the storage capacity of the battery, so it is impossible to estimate how far the car can go.

w is the power number, which theoretically converts into a speed of about 50 km/h; However, the Standardization Administration of the People's Republic of China has issued the "General Technical Conditions for Electric Motorcycles and Electric Mopeds", which stipulates that the speed of electric vehicles produced by manufacturers is not allowed to exceed 20 kilometers per hour. In practice, the speed limit standard adopted by manufacturers is generally higher than 20 kilometers per hour, and the speed of electric vehicles on the market is probably below 40 kilometers per hour and above 20 kilometers per hour. If you use a 72V 40Ah battery, you can theoretically run 100 kilometers on a flat road; If you use a 72v 20ah battery, you can run 50 kilometers on a single bike on a flat road.

But in fact, due to the influence of the road and wind direction and load, the distance run by the new battery will be discounted by 9%, and the distance of the old battery will be reduced by half. Today's batteries decay quickly, and after one year, the battery's energy (stored power) is insufficient.

The maximum speed is about 60 per hour, generally like this, mainly look at the controller, the universal controller is faster, the ordinary controller is up to 50, this is limited, if you really want to buy an electric car, you must change the controller, individual is different, the general modified electric car can reach about 150, the motor power is 4000 watts, the controller is 15000 watts, the battery capacity is 100h, and it is also 72 volts, generally speaking, the larger the capacity, the farther the distance you run, and the speed has nothing to do with it, the speed mainly depends on the discharge current of the batteryThere are also low-capacity high-current batteries, as well as high-capacity low-current batteries.

Speed: In the past, the old electric car was about 60 kilometers, some were bigger than this and some were smaller than this; How far to run, related to other parameters of the electric vehicle, such as the weight of the electric vehicle, the number of w, the larger the number of w, the shorter the distance to run, generally the new battery can run 50 kilometers.

Theoretically around 55km, the battery life is not known, you didn't say how much ah of battery.

According to the formula standard, i=p u can be calculatedCapacity: 50 hours and 50 minutes.

If you calculate it according to 30 kilometers per hour, it is equivalent to about 145 kilometers, and after removing the battery power conversion rate, wind resistance, load, friction and other losses, you can theoretically run 100 kilometers.

The 72V electric vehicle itself has a huge battery capacity, and in the case of one person, under the control of the speed, it can still run a long distance. So when riding an electric car, try to move forward at a constant speed and reduce unnecessary things to carry. If you want to ride far, far away, you need to reduce the power loss.

There is no memory effect of lead-acid batteries for electric vehicles, and a reasonable charging time should be selected according to the electricity situation: in the case of 100% running out of electricity, the general charging time will be 8 10 hours, not more than 12 hours (it will have an impact on battery life), of course, it is not recommended to use up the electricity every time, it is generally recommended that the power consumption is about 70% to charge your car, and the charging time is generally 6 8 hours.

If you are a short-term user, it is recommended that you charge it once a week when your daily power consumption is 10%. When the daily electricity consumption is 20%, it can be charged once every three days.

When the daily electricity consumption is 30%, it can be charged once every two days. When the daily electricity consumption is more than 40%, it can be charged once a day, and the charging time is controlled, generally about 6 hours.

According to the formula standard, i=p u can be calculated

Capacity: 50 hours and 50 minutes.

If you calculate it according to 30 kilometers per hour, it is equivalent to about 145 kilometers, and after removing the battery power conversion rate, wind resistance, load, friction and other losses, you can theoretically run 100 kilometers.

According to the output of 1500w top grid, the theoretical output time is:

t = 72v * 32a * 1 hour 1500w hours.

Under normal car conditions, 1500w is not a big problem to reach 50 mph, so it is about 75 kilometers.

Of course, it is not possible to output the whole time, so the total cruising range must be greater than 75 km.

Taking the average output of 1 kilowatt as an example, the speed can reach about 45 per hour, but the driving time can be longer, 72v * 32a * 1 hour 1000w, about hours, according to this calculation, the range is about 100 kilometers.

The above are all theoretical calculated values, which are actually slightly smaller than the theoretical values.

Just like I put the distance of the electric car, it can reach at least 40 kilometers and the speed can reach 35 kilometers per hour.

The battery can only have 1440 kWh. That is, a maximum of 40 minutes on a full charge. If you press 60 kilometers per hour, the mileage is 40 kilometers.

72V20Ah, motor 2000W, how many kilometers can the cruising range run, (how much time does it take?) )

This design is generally designed to have a range of 100 km.

The motor power is within kilowatts, and if a lead-acid battery is used, the battery will have to be replaced for up to two years. If you use a lithium battery, it is twice as expensive and can be used for 5-7 years.

The 72V800W electric vehicle motor can run up to 70 to 80 kilometers.

The 48V12A can run about 40 kilometers, the 48V20A and 64V12A can run about 70 kilometers, the 60V20A and 64V20A can run about 90 kilometers, and the 72V20A can run about 120 kilometers: the 48V20A of electric motorcycles can run about 40 kilometers, the 60V20A and 64V20A are about 55 kilometers, and the 72V20A is only about 70 kilometers.

Electric vehicle motors are used in the drive motors of electric vehicles. Depending on the environment in which it is used and the frequency of use, the form is also different. Different forms of motors have different characteristics.

Permanent magnet DC motors are commonly used in electric vehicle motors. Electric vehicle motors can be divided into two categories: brushed motors and brushless motors according to the energizing form of the motor; It is divided according to the mechanical structure of the motor assembly.

You can run about 20 kilometers. The speed of 1500W is up to 180 hours

But the time is determined by the capacity of the battery, because the motor determines the speed and the capacity determines the time.

The continuous driving range of an electric vehicle is related to road conditions, driving speed, load, motor power, and battery capacity, which are all variables.

To find out the approximate driving range under these conditions, you can only get the driving range by dividing (the actual capacity of the battery) by (the current at the time of actual driving) (discharge time), and then multiplying (the discharge time of the battery) by (the speed of the battery) by the (speed of operation).

Since these parameters are variables, they are only approximate values.

Battery Expansion for Electric Vehicles:

Lead-acid battery (sealed rechargeable battery): In addition to lithium batteries, lead-acid batteries are also a very important battery system. However, its size and weight have not been effectively improved, so it is most commonly used in automobiles and motorcycles.

The biggest improvement of lead-acid batteries is the recent use of high-efficiency oxygen recombination technology to complete water regeneration, so that the purpose of complete sealing without adding water is achieved, and the life of the "water-free battery" made can be as long as 4 years (single plate voltage 2V).

The advantage of lead-acid battery is that the electromotive force is more stable when discharged, and the disadvantage is that the specific energy (energy stored per unit weight) is small and corrosive to the environment. The working voltage of the lead-acid battery is stable, the use temperature and current range are wide, the charging and discharging cycle can be hundreds of cycles, the storage performance is good (especially suitable for dry charge storage), and the cost is low, so the attitude liquid is widely used.

How many kilometers can a 60v20ah electric car run?

Let's use the data to answer the ...... in detail

Calculate the range of 60V20Ah electric vehicle, 800W power motor, and the speed is calculated as 35 km h;

Calculation: current size = motor power voltage = 800w 60v, that is, the average working current of the electric vehicle is ampere;

Driving time = battery capacity Average current = 20Ah That is, the theoretical driving time of the electric vehicle is hours;

Mileage = speed * driving time = 35km h *, that is, the theoretical mileage of the electric vehicle is about 52 kilometers;

That is: 60V20Ah electric vehicle lithium battery with 800W motor electric vehicle, the theoretical change to a clear grip mileage of about 52 kilometers.

Of course, there are 400W, 600W, 1000W ...... electric vehicle motor powerSpecifically, the actual motor power can be calculated by itself with the above calculation method to obtain the theoretical mileage;

In addition, the above is the calculation of the theoretical data in the ideal state of the basic nucleus, the actual driving process is difficult to achieve consistency, after all, each rider has different weight, different riding habits, different roads, different local climate and environment are also different, so the above theoretical mileage can only be used as reference data.

It can run about 50-60 km.

Don't take the odometer of an electric vehicle as it is generally 30% larger than the exact number.
