If it is a two-wheeled electric vehicle after the electric vehicle is fully discharged, charge the electric vehicle battery, for this problem, as an old master, today to give you an analysis!
First of all, there are many models of electric vehicle batteries, including 48V, 60V, etc., but due to the implementation of the new national standard, there is a clear limit on battery voltage. Therefore, today we will talk more about 48V electric vehicle batteries.
Taking the 48V20AH battery as an example, its average charging voltage is about 51.6V, plus the amount of electricity that needs to be charged is 1.05 times the amount of electricity released, so its charge consumes about 1.08 KWH of electricity (the amount of electricity consumed = the average charging voltage * the rated capacity of the battery *1.05).
It should be noted here that it may be the same pressure but different capacity of the battery, once the capacity is low, then its power consumption will be relatively low, such as 48V12AH battery, the general power consumption of a charge is 0.65 degrees of electricity. Therefore, the greater the voltage and capacity, the more electricity required for a single charge.
In addition, one thing can be explained to you is that the general electric vehicle battery can be fully discharged within 8 to 10 hours, which means that its 48V20AH battery power consumption per hour is about 0.1 to 0.13 degrees, and the 48V12AH battery power consumption per hour is about 0.06 to 0.08 degrees. It can also be seen that in fact, charging an electric car does not consume as much power as imagined.
Of course, the above is also full discharge, in fact, under normal circumstances, when the electric vehicle battery power is less than 30%, it needs to be charged immediately, which can prevent excessive discharge and damage the electric vehicle battery. In addition, electric vehicles can not be charged with the charge, because lead-acid batteries have a certain number of charges and discharges, if frequently charged, will shorten its life.
In short, after the full discharge, to charge the electric vehicle battery, a full need for about 0.65 to 1.08 degrees of electricity (with 48V battery as an example), according to the residential electricity calculation, a full is about 0.6 yuan - 1.6 yuan, quite cost-effective.
I don't know if the question is asked about two-wheeled electric vehicles or four-wheeled electric vehicles, I will give you a calculation.
1. Two-wheeled electric vehicles
Most of our electric vehicles are 60V (5x12V) batteries connected in series, the household two-wheel electric vehicle battery is generally less than two degrees, because the summer charging fast, winter charging slow and other reasons, full of a electricity also fluctuates between 1.2-1.8 degrees, we multiply the electricity, it is a lot of money, quite cost-effective.
2. Elderly mobility scooter
At present, many elderly mobility scooters are electric, speaking of cars, in fact, it is more like a larger version of electric vehicles, and many use a three-wheeled design. The battery of this car is generally 5-9 degrees of electricity, and can be charged with the socket at home, so a charge of 3-5 yuan.
3. Pure electric vehicles
Electricity as the most popular use of new energy, now the new energy vehicle market is also quite popular, different new energy models of tram size difference is large, the common atmosphere on the market is more than ten degrees to dozens of degrees of inequality. For example, a 40 degree electric car is fully charged from 0, it needs more than 20 yuan.
There are several cases
Two-wheeled electric vehicles are charged at home, two-wheeled electric vehicles are generally less than two degrees, the common battery is about one degree of electricity, household electricity is pressed by 6 cents, and a charge is up to one dollar.
Electric low-speed vehicle (elderly scooter), the battery is generally 4-9 degrees, the use of household electricity charging, the cost of 2-5 pieces, depending on the battery capacity
New energy vehicles, common on the market are more than ten degrees to dozens of degrees, different brand models are different, and the difference between household electricity and fast charging piles is obvious. Taking BYD EV360 (battery 42 degrees) for charging in the Beijing area, for example, if there is a garage at home charging, it takes about 20 yuan from 0 to full. If you charge quickly in the charging pile, each KWH of electricity includes a service fee of 1 to 2 yuan, at least more than 40, the maximum may reach 70 or 80 yuan.
