To what extent do charging facilities for electric cars conform to reality?
It’s common knowledge that the entry price of electric cars is too high for many people shopping for a new automobile. With the money you save on gas and the deductions you get, however, the price is readily reduced to a more manageable level. Electric cars, sometimes known as “Zero Emissions” vehicles, are inherently more efficient than their gasoline-powered counterparts. Electricity may be used as a substitute for gasoline in conventional internal combustion engine vehicles, which can result in significant cost savings. Most EVs also have a reputation for being easy to maintain and repair, which can help sway your decision to buy one.
So, what exactly does “alternating current” refer to?
AC stands for “alternating current,” which indicates that the voltage is positive at one moment and negative at another. This change of direction occurs at incredibly rapid rates, quantified by the Hertz (Hz) unit, which measures how many times in a second the direction changes. With a frequency of 50 hertz (hertz), the primary power source provides an alternating current of 230 volts 50 times per second. To utilize an AC charging station, a vehicle must first take in the AC power from the charging station and then convert it to DC power.
For those who are confused, DC power means direct current.
The term “direct current,” or DC, refers to a kind of electrical current in which electrons always go from positive to negative terminals. A power source or transformer is necessary for many electronic devices since they need Direct Current. Direct current devices, such as the battery in your electric vehicle, are easily recognizable by their one positive and one negative pole, as is the case with all batteries.
If you have a DC charging station, you may utilize the DC power it provides to charge your vehicle’s battery quickly using the fast-charging port in your vehicle.
Comparing Alternating Current (AC) vs Direct Current (DC) for Powering Charging Stations
Now that we know the difference between AC and DC charging stations, what does this really mean when making a charging station choice? As the DC power source has less resistance in its energy flow, the charging time at a DC charging station is much less than at an AC charging station. This is because the charging station has a much higher demand on the power grid and must be equipped with an inverter.
Is there ever a time when you wouldn’t want to use DC power?
You may be wondering whether it would make more sense to invest in a DC electric charging station right now. According to Statiq, a DC electric car charging station is the way to go if you need a completely charged car in under 20 minutes. With an AC charging station, this takes between four to eight hours.
It’s not common, though, for a car to need charging in such little time. As a general rule, people who own electric vehicles charge them overnight and then unplug the cables in the morning, whereas businesses often do the reverse. For many hours, the car sits parked and charging in both cases, suggesting that a longer charge time isn’t necessarily a negative thing.
