For many families that do not need to move for a long time and long distance, compared with a car, it is obviously a cheaper electric car that is more convenient and faster to drive on the road than a car, which is more suitable for their travel needs. As a means of transportation with electricity as the most important driving force, electric vehicles are also much better environmentally friendly than cars. But there are still many electric vehicle owners who are curious, how many kWh of electricity can they use to charge the charging pile in the community every day? How much can a charging pile make?
Compared with the car, in addition to the usual road traffic jam is more convenient to pass, the biggest convenience is that there is no need to pay a high insurance, maintenance, cleaning and repair costs every month like the car, and the only cost after buying the car is the electricity bill generated during daily charging.
Generally speaking, how many degrees of electricity an electric vehicle needs to add is determined by the specific battery voltage and capacity it carries. As far as the current electric vehicle market is concerned, there are three most mainstream electric vehicle batteries, namely 48V, 60V and 72V, and the specific capacity of each battery is also slightly different. But as long as there is specific data, it is not difficult to calculate the consumption required for an electric vehicle to be fully charged.
Electric vehicles with different voltages and capacities theoretically need to consume electricity
The 48V batteries currently on the market have two capacities, which are 12AH and 20AH. Theoretically, a 48V12AH battery needs 48X1.167X12AHX1.05, which is 0.705kW·h, that is, 0.7 kWh, from 0 to full charge. Similarly, bringing a 48V20AH battery into the formula shows that it takes 1.17 kWh to fill a 48V20AH battery.
60V battery is currently the most important 20AH and 32AH two types, the calculation method and 48V is exactly the same, as long as the battery voltage X1.167 to get the charging voltage, and then with the charging voltage calculation can be derived, a full 60V20AH battery requires about 1.47 kWh of electricity, a 60V32AH battery needs 2.35 kWh of electricity.
The battery capacity of 72V is generally the same as that of 60V, both 20AH and 32AH. Then through the formula calculation, it can be known that the charge required to charge a 72V20AH battery is 1.764kW·h, and the charging power consumption of the 72V32AH battery is 2.822kW·h, about 2.8 kWh. Of course, this electric vehicle equipped with a 72V32AH battery is also a mainstream electric vehicle model with relatively large power consumption on the market.
Now that we know how much electricity an electric vehicle needs to consume when fully charged, it is not difficult to calculate the revenue of the charging pile operating company. Let's take the battery with a relatively moderate power consumption of 60V32AH as an example, the electricity bill is calculated according to the market price that is 0.5 yuan per kilowatt-hour of electricity, and it takes about 1 yuan to charge a 60V32AH battery.
However, at present, the minimum consumption of charging piles in most communities is 2 yuan, that is to say, the operating unit profit of charging piles can reach more than 100%. In addition, the charging piles in some communities use public electricity, and the consumption cost of charging piles is also reduced again, and this profit is very considerable.
However, in general, charging piles are still a kind of rigid need for electric vehicle owners and cannot be discarded at will. Therefore, as long as the charging pile can provide services for the owners normally, the owners will also be willing to pay for the charging pile to charge.
