Electric vehicles are vehicles that can only be used for charging. The advantage is that the electricity bill is cheap. Compared with the refueling cost of motorcycles with two-wheeled vehicles, the electricity bill with a range of 100 kilometers is only about one-twentieth of the fuel bill of 100 kilometers. However, due to the popularity of smart charging station , people's cheap electricity bill is the impression that the amount of coins is invested for each charge. Recently, a netizen asked: How much electricity does an electric car require for one hour to charge? How long can it last? The little experts will calculate the accounts in detail and tell you the answer.
Currently, mainstream electric vehicles mainly include three voltage parameters: 48V, 60V, and 72V, and they all prefer to carry a capacity of 20AH. Based on this data, we will calculate the power consumption of electric vehicles in detail below. How much electricity does
48V, 60V, and 72V electric vehicles need to charge in one hour?
Although experienced masters can estimate the approximate amount of power required to charge, in order to ensure more accuracy, we calculate the theoretical power consumption according to the formula, and the calculation formula is: power consumption = charging voltage × battery rated capacity ×1.05.
battery rated capacity is 20AH mentioned above, and 1.05 is because charging will consume power. In addition, the charging voltage is 48V charging voltage is about 51V, 60V charging voltage is about 65V, and 72V charging voltage is about 88V. Full charge is calculated in 6 hours, 7 hours and 8 hours respectively.
48V electric vehicle charges an hour and requires electricity : 51×20×1.05=1071wh÷6=178.5wh, which is 0.178 kWh.
60V electric car requires electricity for one hour: 72×20×1.05=1512wh÷7=216wh, which is 0.216 kWh.
72V electric car requires electricity for one hour to charge : 88×20×1.05=1848wh÷8=231wh, which is 0.231 kWh.
is calculated by calculation. The minimum charge of 20AH battery capacity is only 0.178 kWh per hour. According to 0.5 kWh per kWh, it only costs about 8 cents to charge for one hour. How long can the
last for one hour?
calculates the amount of electricity required for charging every hour, and also verifies that charging is really much cheaper than refueling. So, after charging for 1 hour, how far can it support electric cars to travel? We calculate based on battery life = battery voltage × battery capacity × speed ÷ motor power.
Charging for 1 hour How far can a 48V electric vehicle run : Calculate at speed 25km/h, power 400W, 20AH capacity, 48×20×25÷400=60 kilometers, full charge range 60 kilometers, and 6 hours of charging, then, 1 hour of charging is: 60÷6=10 kilometers.
charge for one hour how far can a 60V electric vehicle run? : Based on the speed of 50km/h, power of 800W, 20AH capacity, 60×20×50÷800=75 kilometers, full charge range of 75 kilometers, 7 hours of charging, then, 1 hour of charging is: 75÷7=10.7 kilometers.
charge for one hour how far can a 72V electric car run? : at speed 70km/h, power 1200W, 20AH capacity, 72×20×70÷1200=about 84 kilometers, full charge range is 84 kilometers, and 8 hours of charging. Then, 1 hour of charging is: 84÷8=10.5 kilometers.
Summary of small experts
Through the above calculations, it can be seen that if electric vehicles are charged for one hour, the common 48V, 60V, and 72V electric vehicles only need 0.178~0.231 kWh under the capacity of 20AH. The electricity bill starts at 8 cents. When charging for 1 kWh, the range of 1 kWh is about 10 kilometers. Through the data, I believe that you can experience the cheap and affordable characteristics of electric vehicles.
Then, you can also use the above calculation formula to calculate how long your electric car lasts and how much battery it needs to be fully charged. Comments are welcome to communicate together.
