how to calculate the range of electric vehicles?

how to calculate the range of electric vehicles?

add here text how-to how to calculate the range of electric vehicles? pratik r. sonawane april 22, 2021 related topics how to check, bldc motor hall sensor is working or not? how to check, the ebike controller is working or not? how does a hall effect sensor work? can a one-speed controller run two hub Motors? what are the best tips for buying an electric bike? the range of electric vehicles is difficult to find but not so difficult to predict. yes, we can predict the range of electric vehicles but for that, we need to consider lots of stuff, like how much load is on the vehicle, battery capacity, motor wattage, power to weight ratio, and many more. In this article, we will solve the problem of finding the range of electric vehicles but we are not considering losses during the runlike rolling resistance, friction, aerodynamics. what we are going to calculate will provide an answer, which is closer to the actual answer. first, why it is so much difficult to find out the range of the electric vehicle. the answer is pretty much simple but a little bit unsatisfied. which is related to the one term. “A variable current consumption” you know in electric vehicles, the nature of current flowing through a system is different. it shows variable characteristics. why? because in the case of motor the load is variable hence as a result “current consumption” also shows variation in magnitude. the motors, which are used in electric vehicle applications goes under various conditions like climbing, acceleration, deceleration, braking, and so on. this kind of situation produces different kinds of results. which will affects motor “current demand”. now in the case of the battery, for example: the capacity of the battery is 10Ah and the load current demand is 1 Ampere then we have to calculate how much time does battery is required to drain completely?  the question is easy to answer because the battery is draining a constant current or steady current the answer is 10 hours or 600 minutes. right!! formulae : but as we discussed the current demand for electric vehicles is variable in nature hence it becomes complicated to calculate the exact kilometer or mile range of the Ev’s. therefore, we have to calculate motor current demand at various conditions. types of “current demand” in electric motors: rated current rating peak current rating load current rating note: please be sure before doing a calculation you must have all datasheets and specifications for motor and battery. now let’s start our calculation with an example, calculate the rated current demand for the motor. ex. motor voltage: 60V       motor wattage: 1000W the motor rated current is 16.66A. now, calculate peak current demand for motor as given, motor voltage: 60peak motor power: 1500W motor peak current demand is 25A. thereafter, we need to calculate the load current which will tell us motor current demand when the load is applied on it. (assume, the load is vehicle plus driving person and luggage weight) now, calculate the power to weight ratio requirement.  ex.   motor maximum loading capacity: 350 kgpeak power: 1500W from calculation power to weight ratio : 4.28 W/Kg how to calculate the range of electric vehicles? consider,  the bike load (including all-electric accessories) is 150 kg and Mr. Musk is driving it and you know  Mr. musk is a healthy person so maybe his weight is around 75kg. suppose Mr. musk doesn’t know how many miles his car can cover! therefore, let’s help him to find out the range of his vehicle. so the total weight of the vehicle will be 230 kg. to find motor power consumption during load, multiply P/W ratio with vehicle total weight. power consumption under load condition is 984.9 Watt. now we need to find out the current demand under load condition as given, motor voltage: 60Vmotor wattage: 984.9W from the calculation, the current demand under load condition is 16.40A did you notice we got three nature of current? rated current peak current load current these three natures of current are nothing but a result that came from different situations or circumstances. “rated current” is flowing through a system when the motor is working under its full efficiency.“peak current” is flowing through a system when the motor is under acceleration or initial pick-up.“load current” is flowing through a system when the motor is working under load conditions. now, we have to find the value of the average current. average current demand will be 19.35A this is it! the above answer can help us to understand the nominal current demand for vehicles. this is an average current demand for electric vehicle motors. let’s assume you design a Lithium-ion battery pack of 60 volts with a capacity of 100Ah. Also, read | How To Calculate Battery capacity for an electric vehicle. divide that batter capacity by average current demand. hence battery backup will be 5.17 hours. consider, your electric vehicle average speed is 45 km/h then the range of the vehicle will be 232.65 kilometers or 144.78 miles!! but this is not an exact answer. during the run, there is an instantaneous rate of change of current consumption. hence 233 ± 10 kilometers (145 ± 6.21 miles) is always better to assume. this is one of the ways we can find out the range of the electric vehicle. hopefully, you found your answer in the article.  Note: the range of the electric vehicle may vary with surrounding situations or circumstances. download “formulas for calculating range of the electric vehicle.pdf“ calculate your range of the vehicle by using “range calculator” range calculator article by author name Lorem ipsum dolor sit amet, consectetur adipiscing elit.

can electric scooter go up hill?

can electric scooters go uphill?

add here text general can electric scooters go uphill? pratik r. sonawane December 13, 2021 related topics how to check, bldc motor hall sensor is working or not? how to check, the ebike controller is working or not? how does a hall effect sensor work? can a one-speed controller run two hub Motors? what are the best tips for buying an electric bike? yes, electric scooter can go uphill but it depends upon the system, like a type of powertrain, power(w), supply voltage. the practical experiment proves that the range from 250w to 500w motor is not capable of climbing uphill but it also depends on how much “rated voltage” is applied to the motor. if the voltage is 48v then it is impossible to go uphill because it can not produce high torque. the possibility increases when the voltage is above 48v. like 60v, 72v so the overall answer is, select a electric scooter that has a supply voltage of more than 48v and power should be above 500wone thing that is very important in EV’s is “the power” for better understanding see the chart. total load (kg), hill angle is considered a constant value.  article by author name Lorem ipsum dolor sit amet, consectetur adipiscing elit.

how to calculate battery capacity

how to calculate the battery capacity

add here text calculation how to calculate the battery capacity pratik r. sonawane November 16, 2021 related topics how to check, bldc motor hall sensor is working or not? how to check, the ebike controller is working or not? how does a hall effect sensor work? can a one-speed controller run two hub Motors? what are the best tips for buying an electric bike? To find “battery capacity for electric vehicle” First, you must need some basic information about motor like how much load you can put on a vehicle Always remember, in the electric vehicle the weight (kg) is an important aspect. Because if you want to design a vehicle in such a way that can handle more people on the vehicle rather than accessories then you must care about not taking any extra load on the vehicle except basic components. So let’s begin our calculation Before calculation, we need the following parameters Motor voltage (V)Motor power rating (W)Motor peak power rating (W)motor maximum loading capacity (kg) On the other hand, your valuable wishes like Wish #1 How much distance do you want to cover in a single charge? Wish #2 How much weight do you want to carry with your vehicle? Wish #3 What will be the speed of the vehicle when the vehicle is “loaded”? So first you have to put your extra activities aside for the next 15 minutes. It is really a simple calculation. Let’s do our first calculation Now you may think, “Is it a hard calculation?” Ha-ha, it’s not. My work is to explain it deeply and your work is to understand it carefully. Now let’s get back to the topic. We find our first answer that how much current does the motor need to work at full efficiency. Next, calculate motor peak current rating. Do the same calculation as above. Now, we got two parameters that will help us to find the battery’s “C rating”. The third parameter will help us to find how much “load current” does require to motor for performance. To calculate Max. Power to weight ratio, As we know what is the peak power rating of the motor and what is the maximum loading capacity of the motor. Both the parameters are important to know the motor limitations. Therefore, Now multiply the max. P/W ratio with how much weight you want to carry with your vehicle (wish #2) It will show, how much power does the motor consume under load condition. Now from “motor power under load condition” we can calculate motor “load current”. If you observe that we have three nature of current, Motor rated current Motor peak current Motor load current Always remember for Ev’s the basic technical statement is, “Nature of current flowing through the system of the electric vehicle under various circumstances is always show a variation in magnitude during acceleration or deceleration”. hence to calculate a precise value for battery capacity we have to calculate the “average value”. The “average current” is equal to require battery capacity, which is obviously a minimum requirement. For example, If your vehicle consumes “average current” 18A (battery capacity 18Ah) and you are getting an average speed of 45km/hr. So theoretically, the vehicle can run only 45 km because it has a battery backup of 1 hour. Now let’s calculate the battery capacity as per your wishes. Remember, you have two wishes left!! Now wish #1: How much distance do you want to cover in a single charge Example. Say 1000 km!!! Or do you want to ride to the moon?  Let’s hope this is not your wish because then you have to make a battery that is bigger than the size of a rocket! ha-ha. So 1000km is enough for us. How much distance do you want to cover in a single charge: 1000km Next wish #3: What will be the speed of the vehicle when the vehicle is “loaded”? Example 100km/hr and average current 50Ah Good, this is it!! You got your answer! Now, I am sure you understand the calculations.

why electric vehicles failed in the early 18th century

why electric vehicles failed in the early 18th century

add here text Fig 1.3: Gustavo’s electric tricycle general why electric vehicles failed in the early 18th century pratik r. sonawane October 18, 2020 related topics how to check, bldc motor hall sensor is working or not? how to check, the ebike controller is working or not? how does a hall effect sensor work? can a one-speed controller run two hub Motors? what are the best tips for buying an electric bike? hello everyone welcome to the blog. in this blog, we are going to talk about ev. but wait ev? what is ev? any guesses? umm “electron volt”,” enterprise value’’. well no! actually, we are going to talk about other ev which means electric vehicle. yeah, now we all know about what we are going to talk about in this blog. alright, now we know ev means electric vehicle but wait who invented this concept? who created this word? where it comes from? well, I also don’t have an idea but we have to find this for that I think we have to go back in time. so let’s go!!!! Fig 1.2: Sir Ányos Jedlik Well, what is this pic? it’s the first EV model made in 1828 by Sir Ányos Jedlik (Hungarian) (fig 1.0.2) scientist. He invented the early stage of the Electric (ELEKTRO) motor later then he created this small EV model (fig 1.0.1). What a brilliant guy. Later, many brilliant minds came up and made various astonished and practical running EV cars awesome right.   Do you guys want to know who created the first practical EV model? it’s Sir Gustavo trouve’s (1881) (fig 1.0.3) he made the world’s first EV tricycle. Then Thomas parker (1895) (fig 1.0.4), Thomas Edison (1913)(fig 1.0.5), and in the modern world, there is TESLA (2015) (fig 1.0.6) also there are many models made by many inventors. Fig 1.3: Gustavo’s electric tricycle Fig 1.4: Parker’s electric car Fig 1.5: Thomas Edison’s electric car Fig 1.6: TESLA electric car Now might be you guys are thinking if EV was invented in 1881. Then why it’s booming these days! Curious? Well yeah, I was also thinking the same. EV’s are way more reliable and eco-friendly than today’s pollution-making petrol and diesel vehicles. I always wanted to know this but then I found my answer but for you let’s go back to the era where the madness of EV started. Fig 2.1: Oil well Fig 2.2: Sir Hendry ford Fig 2.3: Ford’s first car  In 1846 the revolution of the oil industry began. We all know the crude oil-rich source of many precious and important raw materials which made tremendous evolution human history. By refining crude oil we get many resources, petrol and diesel are one of them. In 1896 sir Henry ford (fig 2.2) invented the first gasoline-running automobile which was very affordable for any middle-class family at that time and because of that, the hype of Ford’s car(fig 2.3) went to peak in urban locals. Compare to this less expansive car EVs were costly due to a lack of research and unviability of advanced technology. Making the cost of batteries for EV was expensive and maintenance cost was also high because there was no advancement in battery manufacturing. So because of this people tends towards less expensive gasoline running cars which were become the main reason for the falling EV industry. Fig 3.1: Sir Stanley whittingham Fig 3.2: lithium ion battery But today because of advanced technology and many years of research we are able to make reliable EV which is good right. But wait which advance technology made EV this reliable? The answer to this question is hidden in the late 1970. In this year the revolutionary era of battery technology began. In 1970 oil crisis was at its peak so in this period Sir Stanley Whittingham (fig 3.1) invented a lithium-ion battery (fig 3.2). This invention becomes a milestone in the EV revolution. Why? Because lithium-ion batteries (Li-ion) are rechargeable, means even after draining all his energy you can recharge it back easily like you do recharge your cell phone interesting right. This makes EV more reliable still there are lots of advancements that are lack in EV but EV’s are the best alternative against petrol and diesel cars. Yeah, why not, you can recharge your car battery and use it again in your car until the life of the battery ends by the plugin, not like the combustion cars have to refuel every time but can’t reuse the same fuel again and again. This makes EV’s way better than petrol cars. Fig 4.1: Electric vehicle Fig 4.1: Hybrid vehicle The concept of EV is simple just run your car or bike or bicycle with help of an electric motor, powered by Batteries. Now most of us are thinking. We have already bought gasoline/diesel running cars so we must have to buy EV separately. don’t get sad actually, our engineers have developed various technology. By which you can simply just convert your traditional cars into EV just replace your engines with electric motors. cool, right! or if you don’t want to go fully electric vehicle then you can make it a hybrid car/bike. Hybrid car/bike what is this now? Well, let me tell you the concept of hybrid in this the car or bike run with a combustion engine as well as battery. The only difference is these cars or bikes don’t have the plug-in option, batteries are getting charged by the combustion engine or regenerative power from the braking system. Hybrid cars also do have demerits like the maintenance cost is high they are not environment friendly like EV also they aren’t that much powerful. So better we prefer EV. These days big problems like global warming and slowly ending conventional resources governments of many countries start looking towards EV as the best alternative green energy and eco-friendly source. For building a great community and awareness of EV this blog is my small initiative towards it. I believe
