EV chargers are energy supply facilities that maintain the operation of electric vehicles.
They usually charge electric vehicles in various scenarios such as public buildings, shopping malls, residential parking lots, or charging stations according to different voltage levels.
Nevertheless, the charging situation varies in different places. There are so many factors in the process of EV charging market development.
1. Charging speed
We can always hear people talking about electric cars, and the first unavoidable topic when talking about electric cars is charging speed.
That’s because it directly determines the user experience. Currently, EV chargers can be divided into AC chargers and DC chargers, the former is slower and the latter is faster.
Let’s say AC chargers first. The AC charger is a power supply device that is fixed outside the electric vehicle and connected to the AC power grid to provide AC power for the onboard charger of the new energy vehicle.
The AC charger itself has no charging function but only functions to control the power supply.
However, the power of AC home chargers will not be high, and mostly 3.5kw and 7kw. And also the electricity from the chargers can not be charged in the car directly.
The actual voltage transmitted by the power grid is high-voltage direct current,
which is converted into usable household direct current through the action of the rectifier,
which is what we often call 220V voltage. The function of the onboard charger is similar to the rectifier inside an electric car, which can convert AC into DC electricity to charge the car.
Then let’s say DC chargers. DC charger is generally called “fast charging”. It is generally connected to the AC power grid and can be used as a power supplement for off-board electric vehicles.
It is a power control device for a DC working power supply that can provide sufficient power. The output voltage and current can be continuously adjusted, effectively achieving fast charging requirements.
Fast charging: DC charging piles can quickly charge electric vehicles at high power, and can usually fully charge the battery in a short time.
DC charging piles convert AC power into DC power, which can utilize electric energy more efficiently and reduce energy loss during the charging process.
Wide scope of application:
DC charging piles are suitable for various models and brands of electric vehicles, with wider compatibility.
2. Charging problems
There will be some words usually: “What happened to this charger? Why cannot I charge my car?” ”Save your energy, just one left here is available.”
This situation usually happens in some stations. However, there are usually so many problems happening in the charging process.
Like the adaptability between the chargers and the electric cars, power supply, cable stability, and so on. Operators will always face these problems when they are operating the chargers.
Sometimes the charging speed will be not fast enough for cars to charge; Sometimes the charging cable will be broken by discarded carelessly; Sometimes the payment system will pause on one page; Sometimes after the programming of the new software the cars, the chargers will display errors due to the incompatibility between the chargers and the cars.
No matter what kind of difficulties we are facing, we will always look forward and keep charging the electric world!
