Whenever I talk to people about electric vehicles (EVs), I often hear the idea that the cruising range of electric vehicles is not long enough to travel far distances. Although Tesla and several other car manufacturers have launched vehicles that travel more than 200 miles, the above problems are largely true. At the same time, there is another influencing factor: the lack of charging stations has greatly weakened the attractiveness of electric vehicles. These ev charger station must be everywhere like gas stations, and electric vehicles can be popularized in the market.

It is expected that the number of electric vehicles will continue to increase in the next five years, and will show a significant growth of more than 50% on a global scale. Driven by this trend, ev charger station and charging stations will also develop rapidly. The charging post is similar to a ev charger station that converts alternating current to direct current to charge the vehicle's battery. However, the ev charger station can only be converted from alternating current to alternating current, and more concerned with diagnosis and monitoring. Due to the government's new incentives, the speed of development of these systems has accelerated.

There are three main levels when charging an electric car. It is important to understand these three levels before charging:

Level 1 charging refers to the standard 110VAC outlet in our home. This is the basic AC to DC conversion that powers electric vehicles. However, charging takes a long time: for example, it takes 5 to 6 hours for a Chevrolet Volt with a range of 40 miles. But most drivers start charging at night, then go to bed and get fully charged in the morning.

Level 2 is residential and commercial form charging. For residential use, the secondary AC ev charger station transmits at 240VAC and 30A, similar in level to a domestic washer/dryer. These ev charger station are built for single-family homes; that is, one user. In commercial use, secondary charging is not only transmitted at 240V and 30A, but also has an intelligent network. With an intelligent network, the owner of a commercial entity can manage the ev charger station and see how many electric cars are charging in the charging station, as well as other functions, etc.

Level 3 is a fast DC ev charger station that can fully charge an electric car within half an hour. The tertiary ev charger station has no conversion of AC and DC. However, today's shortcoming is the lack of standards; there is no standard plug. There are two competing standards in the United States and Japan.
