220v and 12v electrical circuits of charging piles

This time we introduce the 220v and 12v electrical circuits inside DC charging piles.

220v electricity is the most frequently used in our daily life, but the 220v electrical circuit can be used when it is really necessary. The reason why we still need to understand these is that safety is a big deal, we must do 100% protection, learn more about electricity rules, and let more friends master the ability to use electricity safely.

In the 220v electrical circuit, take the Bluesky brand as an example:

What are the 220v electrical circuits in the charging piles we provide?

220v power supply, 220v external device power supply socket, double-circuit meter, high-voltage circuit breaker relay power supply, 12v power supply, advertising screen power supply, heater power supply, lighting lamp strip lamp beads, some brand fans, some brands of main control board power supply, induction coil power supply, liquid cooling pump power supply, etc.

Of course, all the above external power consumption is often required by customers in our actual production, and we support all personalized requirements of customers.

There are two functions of 220v voltage:

  • Power conversion and external equipment
  • Device power supply

In actual charging needs, charging piles do not provide external devices when they are produced. Even if it is power conversion, the earliest charging piles will use batteries to power the low-voltage needs of car startups based on the requirements of safety and stability.

Now we directly use 220v to convert low-voltage power supply to 12v or 24v, with power ranging from 75w, 150w, 200w, and 320w. Of course, a low-voltage power supply will also be connected to some devices, and it is a booster for powering components. Most manufacturers use low-voltage power supplies for control panels.

In the beginning, car charging has always been based on 7kw small household piles, while AC chargers do not require starting power, DC charging is not popular, and the utilization efficiency of car space, or preventing electric vehicles from being unable to charge autonomously after excessive power loss, etc., all make low-voltage power supply the top priority of the communication bridge between charging piles and cars. Low-voltage power supply is certainly a safe power supply, and it has limited harm to the human body and cannot be used illegally at will.
