The use of electric vehicles needs to be charged frequently, as the management of electric vehicles is becoming more and more strict, only charging piles can be used in the community, but it is often seen that some netizens complain about the charging piles in the community, charging is not satisfied, running not far and charging more, so how many kilowatt-hours of electricity do we need to charge our electric vehicles once?
How many kilowatt-hours does it take to charge an electric car?
Some people say that you can connect to the meter, or some sockets that can measure the degree, in fact, there is no need to be so troublesome, we only need to calculate, we can roughly understand how many kilowatt-hours of electricity are needed to fully charge the electric car.
There are two important parameters of electric vehicle battery, namely voltage and capacity, such as 60V20Ah battery, battery voltage is 60V, battery capacity is 20Ah, through the knowledge of physics, we can know that the battery voltage multiplied by the capacity of the battery is the total wattage of the battery.
For example, the total wattage of a 60V20Ah battery is: 60×20=1200Wh, which is 1.2 kWh.
That is to say, the 60V20Ah battery needs 1.2 kWh of electricity to be charged once, and some netizens may say that when charging the electric vehicle battery, there is no power consumption, which is indeed the case, but when the electric vehicle battery is charged, there must be some power left in it, such as 20% or 30% of the power, it can be said that the actual power used is smaller than the calculated value.
Through the above formula, let's calculate how many kilowatt-hours of electricity it takes to fully charge a common battery:
48V12Ah=48×12=576Wh, that is, 0.576 kWh;
48V20Ah=48×20=960Wh, that is, 0.96 kWh;
72V20Ah=72×20=1440Wh, that is, 1.44 kWh;
72V32Ah=72×32=2304Wh, that is, 2.3 kWh;
Can 1 yuan be filled?
Charging electric vehicles on the charging piles in the community, many of them are directly charged two yuan each time, or even more, some of the charging piles in the community are charged according to the power and hours, but each charge costs 3~4 yuan, so when charging the electric vehicle, how much does it cost?
Although the charging cost is different in various places, it can be seen through the news on the Internet that the electricity fee of the charging pile in the community has been optimized, and the price of electricity has been reduced, and the charging cost of the charging pile in the community is basically about 0.5 yuan, and we will calculate it according to 0.5 yuan, how much does it cost to charge a common battery.
A 48V12Ah battery requires 0.576 kWh of electricity to be charged once, which is 0.57*0.5=0.285 yuan;
A 48V20Ah battery requires 0.96 kWh of electricity to be charged once, which is 0.96*0.5=0.48 yuan;
A 60V20Ah battery needs 1.2 kWh to be charged once, which is 1.2*0.5=0.6 yuan;
A 72V20Ah battery needs 1.44 kWh to be charged once, which is 1.44*0.5=0.72 yuan;
A 72V32Ah battery needs 2.3 kWh of electricity to be charged once, that is, 2.3*0.5=1.15 yuan;
Through the above calculations, we can see that the cost of charging a charge is still relatively low for some of the most common electric vehicles, and one yuan can be fully charged, but some large-capacity electric motorcycles have a charge cost of more than 1 yuan, especially for batteries with a capacity of more than 32Ah.
In fact, at present, major cities are only allowed to use the new national standard electric vehicles, so if the electric vehicle is charged once, if only one yuan is charged, the charging pile in the community can also earn double the cost, or even more, the key is that some communities will charge 2~4 yuan, so the cost will be more.
Summary:
How many kilowatt-hours of electric vehicle charging can be calculated by the voltage and capacity of the battery, and the amount of electricity required for a battery charge is generally understood. So, what do you think about this? #文章首发挑战赛#
