What is a charging pile?

What is a charging pile? A charging pile is a special power device for charging electric vehicles, similar to a gas pump in a gas station. The following is some introduction to charging piles:

1. Components of a charging pile

The charging pile is mainly composed of a pile body, an electrical module, a metering module, etc., and generally has functions such as power metering, billing, communication, and control.

2. Types of charging piles

There are many types of charging piles, which can be classified from multiple angles:

2.1. Classification by charging type:

2.1.1. AC charging pile (slow charging): generally a small current, a small pile body, and flexible installation. The charging time is long, and it usually takes 6 to 8 hours to fully charge a small car.

2.1.2. DC charging pile (fast charging): generally a large current, a larger charging amount in a short time, a larger pile body, and a large occupied area (heat dissipation). Suitable for fast DC charging of electric buses, minibuses, hybrid buses, electric cars, taxis, engineering vehicles, etc. Fast charging piles mainly refer to charging piles with a power greater than 60kW. Fast charging is AC input and DC output, which directly charges the vehicle battery. The specific charging speed and duration are determined by the vehicle. Different models have different power requirements and charging speeds. Generally, 80% of the battery capacity can be fully charged in 30 to 40 minutes.

2.2. Classification by installation method:

2.2.1. Vertical charging pile: mostly used for public charging piles, suitable for outdoor parking spaces and charging stations. No need to lean against the wall, it can be directly installed in the open air, suitable for outdoor parking spaces or community parking spaces, and installed in the carport if conditions are good, which can protect the vehicle and charging equipment.

2.2.2. Wall-mounted charging pile: It needs to be fixed to the wall and is suitable for use in private parking spaces such as underground parking lots, which saves space and is convenient for charging.

2.3. Classification by service object:

2.3.1. Public charging pile: It is purchased by government agencies and other institutions with public service nature, and the service object is for all electric vehicle owners, such as public parking lots. Public charging piles generally use DC piles, with high charging power and short charging time, which are suitable for users who need to charge urgently or travel long distances.

2.3.2. Dedicated charging piles: mostly built by enterprises, serving customers and internal personnel, such as shopping mall parking lots.

2.3.3. Self-use charging piles: private charging piles, installed in private areas, not open to the public. Suitable for daily commuting and users with fixed parking spaces, slow charging can be used at night or during rest time, which will cause less damage to the battery and help extend the battery life.

2.4. Classification by protection level of installation location:

2.4.1. Indoor charging piles: The protection level needs to be at least IP32 or above. Because it does not need to face the extreme environment of the outside world, the relative safety risks are relatively small and the cost is relatively low.

2.4.2. Outdoor charging piles: need to face the harsh environment of wind and rain, and must have better insulation and lightning protection conditions. Its protection level must reach at least IP54 to ensure personal safety, vehicle body safety and charging equipment safety.

2.5. Classification by the number of charging ports:

2.5.1. One pile one charge: At present, the charging piles on the market are mainly one pile one charge, which is suitable for general parking spaces and individual users.

2.5.2. Multiple charging at one pile: It is more common in large parking lots such as bus parking lots and logistics parks. It can support multiple electric vehicles charging simultaneously, speed up charging efficiency, and save labor and site costs.

3. Functions of charging piles

The main function of charging piles is to convert the power of the power grid into the power of electric vehicle batteries. Its general functions include:

3.1. Provide reliable AC or DC power supply.

3.2. Provide self-service charging operation function.

3.3. Correctly measure the power consumed by charging and charge users accordingly.

3.4. Have unattended operation control and remote monitoring functions.

In addition, charging piles are usually equipped with display screens and human-computer interaction interfaces, which can display data such as charging amount, cost, charging time, etc., and support users to charge and pay by swiping cards or scanning codes.

4. Precautions for the use of charging piles

4.1. Charging matching: The charging speed of electric vehicles depends on whether the power of electric vehicles and charging piles matches. The BMS system inside the electric vehicle actually controls the charging power. Only when the power of the electric vehicle and the charging pile matches can the optimal charging state be achieved.

4.2. Rainy and snowy weather: At present, the protection level of most outdoor charging piles on the market is around IP54, which can play the role of dustproof, rainproof and lightning protection. When charging in rainy and snowy weather, as long as the vehicle interface is not in the rain and the gun head is dry, the charging can be started normally.

4.3. Safe distance: It is best not to stay in the car when charging an electric car, and do not use air conditioning, audio and other equipment, because this may cause the battery thermal management to be out of control, and in severe cases, it may cause leakage, fire, explosion and other accidents. It is best to keep a distance of more than 2 meters from the vehicle when charging.
