Science: How to choose electric car charging post, which is better to choose DC charging post or AC charging post?

What are the considerations for choosing an EV charging post, and whether it is better to choose a DC charging post or an AC charging post. From the consideration of using demand, the overall cost of DC charging pile is high, and the cost of AC charging pile is low. If it is a personal installation of charging piles, it is recommended to use AC charging piles. The charging power of AC charging piles can reach a maximum of 7KW, and it takes 6-10 hours to be fully charged on average, and the electric car will be parked directly after returning home from work and charged without delay the next day. And the demand for power distribution is not very big, common 220V power supply can be accessed and used. Individuals do not have too high requirements for full time, DC charging piles are suitable for new communities, parking lots, and for places where charging mobility is relatively large.

From the installation point of view, DC charging piles are more expensive to install, and the wiring is even more expensive than the equipment cost. AC charging piles can be used when they are connected to 220V power supply. The maximum charging power of AC charging pile is 7KW, the charging power of DC charging pile is generally 60KW to 80KW, the input current of single gun can reach 150A – 200A, which is a huge test for the power supply line, the general community transformer basically can not take a few such charging piles, the old community even one can not be installed. The charging power of some large vehicle DC charging piles can reach 120KW to 160KW, and the charging current can reach 250A, which is very strict to the construction line and high to the load of power distribution cabinet.

From the user’s point of view, the faster the charging speed, the better. If you use DC charging pile, the charging will be finished in about 1 hour at most, if you use AC charging pile, it may take 6 – 10 hours to finish charging, if you need to use the car urgently or run long distance, this charging method is extremely inconvenient, certainly not fuel car refueling. Convenient and fast.

All things considered, when choosing a charging post, you have to choose the right one according to the actual situation. Residential communities try to choose AC charging piles, the load on the power supply is small, after work to charge a night, basically everyone can accept. If it is in public places, public parking lots, public charging stations, shopping malls, theaters and other public places, it is more convenient to install DC charging piles.
