How do I choose a charging station?

In addition to price, many variables need to be considered. The most important is the power output, which should be at least as good as the power of the car charger, and ideally higher, so that it will be sufficient in the future.

First, you need to know the purpose and location of the charging station. Different charging stations have different requirements. You need to consider what performance you need and the type of connector and cable connection.

● Power supply of charging station

On board charger and charging station (electric vehicle power supply equipment) are two important chargers for electric vehicles.

Principle: The car charger is placed inside the car, and the charging station is external. The charging station is the source of power, which is then sent to the vehicle charger. During AC charging, the vehicle charger load converts AC power into DC power, and then sends the power to the battery. Because the current must pass through the car charger, its performance is very important. The EVSE charging station cannot provide more energy for the car than can be provided by the car charger. Therefore, the minimum power required by the household charging station is the same as that of the car charger.

● Smart computer

Electric vehicles can be charged directly from the socket using a portable charger. External charging stations are not absolutely necessary, but they have many other clever functions besides simply ensuring the safety of vehicles and passengers.

For companies with more employees, it is better to choose charging stations that can communicate with each other and provide so-called “load balancing”, that is, charging stations use full power until they reach the capacity of power connection and power is distributed “fairly” among all vehicles.

For families, it is also beneficial to be able to connect the charging station to the house and adapt it to the energy demand of the house. During full operation, smart charging stations only use “free” current, and when the capacity is released, they will start charging. Or, on the contrary, if the demand for houses increases, it will reduce the charges. Alternatively, the home charging station can be programmed to charge only during the night charge period, when the charge is the cheapest.

● Cable and connector type

The variables to consider are the type of cable and connector. There are two options, one is the station with integrated cable, the other is the station with only one socket, and then everyone connects the cable they carry in the car to the socket.

If there are different cars entering the station, or if you have a car with Type 1 connector, you can consider choosing a station with only sockets, which will make it more widely used. If it is a home station and you are the only one charging there, and if you already have a Type 2 connector, your future car will also have the same connector, then the integrated cable station will be much more convenient, because you need to always open the package of the portable charging wire.
