Popular Science | Is the longer the gun line of the charging station, the better?

The length of the wire of the charging station is usually determined by multiple factors, including the design, purpose and installation location of the charging station.

 

The length of the wire of the charging station is usually determined by multiple factors, including the design, purpose and installation location of the charging station. Generally speaking, the length of the wire of the charging station will be designed according to actual needs to meet the charging needs of users.

 

1. Construction principles

The length of the wire of the charging station can be designed according to user needs, but the following construction principles must be followed:

First, safety. It is necessary to avoid the risk of tripping or vehicle running over caused by the charging gun line being too long.

 

Second, efficiency of use. Too long charging gun lines will cause power loss and affect charging efficiency.

 

In addition, cost issues. Longer gun lines mean higher costs, including materials, installation and maintenance costs.

 

2. Design ideas

For home charging stations, the wire length is usually around 3-5 meters. This length is to facilitate users to charge in their garages or parking spaces at home. In addition, home charging stations are usually installed in fixed locations and do not need to be moved frequently, so shorter wire lengths can reduce the clutter and entanglement of wires.

For commercial charging stations, the wire length may be longer, usually 5-10 meters or longer. Commercial charging stations are often installed in public parking lots, shopping malls, hotels and other places, and the parking positions of users' vehicles are different. Therefore, in order to meet the needs of different vehicles, the length of the wire is relatively long so that users can easily park their vehicles in a suitable location for charging.

 

Public charging stations are located in open parking lots, roadsides, shopping malls and other places. The parking position of the vehicle may be far away from the charging station, so the charging gun line needs to be longer to adapt to different parking situations.

 

However, even so, its length should not usually exceed 5 meters, because too long gun lines are easy to become a dangerous source of stumbling in public places, and it will also increase power loss and maintenance costs. For example, for some special scenarios, such as temporary charging needs during long-distance travel, longer wire lengths can be used to charge in places where there are no fixed charging stations.

 

3. Installation strategy

Public charging stations are based on the universality of services, and the length of the gun line needs to comprehensively consider various factors such as economy and practicality. Industry insiders pointed out that in order to avoid the problems caused by the excessive length of the charging gun line of the community charging station, the following strategies can be adopted:

First, reasonably plan the location of the charging station. When planning a home charging station, the vehicle parking area should be taken into consideration, and the charging station should be set as close to the parking space as possible, so as to reduce the length of the gun line.

 

Second, use an automatic retractable or winding device. Some charging stations are equipped with an automatically retractable charging gun line or a storage box. When the vehicle approaches, the gun line can be extended to an appropriate length and automatically retracted after use to prevent the gun line from being too long and scattered.

 

Third, use a charging station with an adaptive gun line length. At present, some brands in the industry can provide retractable charging gun lines. Such charging stations can automatically control the release length of the charging gun line according to actual use, thereby avoiding the above-mentioned problems caused by the excessive length of the gun line.

 

Fourth, strengthen gun line management. Use cable clamps, straps or other fixing devices to manage the charging gun line to avoid being dragged at will and reduce wear and tear and tripping risks.
