The length of the cable for charging stations is generally determined by several factors, including the design, purpose, and installation location of the charging station. Typically, the length of the cable is designed to meet the practical charging needs of the user.

1. Choosing cable length based on usage scenario

For public charging stations, the cable length is usually between 5 and 10 meters or longer. Public charging stations are often installed in places such as parking lots, shopping malls, and hotels, where the parking positions of users' vehicles vary. Therefore, to meet the needs of different vehicles, the cable length is relatively long, allowing users to park their vehicles in appropriate positions for charging. However, even so, the length should generally not exceed 5 meters, as excessively long cables in public areas can pose a tripping hazard and also increase power loss and maintenance costs.

For home charging stations, the cable length is typically around 3 to 5 meters. This length is convenient for users to charge their vehicles in their garages or parking spaces at home. Moreover, home charging stations are usually installed in fixed locations, so shorter cable lengths help to reduce cable clutter and prevent tangling.

2. How to avoid the issue of excessively long cables

For public charging stations, considering the universality of the service, the cable length needs to balance factors like cost-effectiveness and practicality, so longer cables are necessary.

For home charging stations, to avoid problems caused by excessively long charging cables in residential areas, the following methods can be used:

1) Properly plan the installation location of the charging station.

When planning a home charging station, consideration should be given to the vehicle parking area, and the station should be placed as close to the parking spot as possible. Typically, it is set behind the parking space to minimize the required cable length.

2) Choose charging stations with retractable cables.

Some charging stations are equipped with automatically retractable charging cables or cable reels. When the vehicle is close, the cable can extend to the appropriate length, and after use, it can be retracted to prevent the cable from becoming too long and scattered.

3) Strengthen cable management.

Use cable clips, straps, or other fastening devices to manage the charging cable, preventing it from being dragged around. This reduces wear and the risk of tripping.

3. Design principles for charging station cable length

The cable length of a charging station is not always better when it is longer; it should be designed according to the user's needs and follow these design principles:

1.Safety: It is important to avoid the risk of tripping or vehicles running over excessively long cables.

2.Efficiency of use: Longer cables can cause power loss, which affects the charging efficiency.

3.Cost: Longer cables incur higher costs, including for materials, installation, and maintenance.

In conclusion, when purchasing a home charging station, electric vehicle owners should consider their specific needs and choose an appropriate cable length.
