What is the Appropriate Length of Charging Cable of the EV Charger?
The length of the cable of a charging pile is usually determined by multiple factors, including the design, purpose and installation location of the charging pile. Generally speaking, the cable length of the Maruikel charging pile will be designed according to actual needs to meet users’ charging needs.
Design Principles
The length of the charging cable of a charging pile can be designed according to user's needs, but the following design principles must be followed:
First, safety. It is necessary to avoid the risk of people tripping over due to an overly long charging cable or the cable being run over by vehicles, ensuring the safety of users.
Second, efficiency of use. An excessively long charging cable will increase power loss and reduce charging efficiency.
In addition, cost issues. A longer cable means higher costs, including materials, installation and maintenance costs.
Design Ideas
For home charging piles, the cable length is usually around 3-5 meters. This length is designed to facilitate users to charge in their garages or parking spaces at home. In addition, home charging piles are usually installed in fixed locations and do not need to be moved frequently, so shorter cable length can reduce the clutter and tangling.
For commercial charging piles, the cable may be longer, usually 5-10 meters or longer. Commercial charging piles are often installed in places such as highway service areas, public parking lots, and shopping malls, and the parking locations of users' vehicles vary. Therefore, in order to meet the needs of different vehicles, the cable length is relatively long so that users can easily park their vehicles in suitable positions for charging.
Public charging piles are located in open parking lots, roadsides, shopping malls, etc., and the parking location of the vehicle may be far away from the charging pile. Therefore, the charging cable needs to be longer to adapt to different parking situations.
However, even so, its length should not usually exceed 5 meters, because too long cables are easy to become a tripping hazard 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, a longer cable can be used to charge in places without fixed charging piles.
Installation Strategy
Public charging piles are based on the universality of services, and the charging cable needs to take into account various factors such as economy and practicality. Industry insiders pointed out that to avoid the problems caused by the excessive length of the charging cable for the community charging pile, the following strategies can be adopted:
First, reasonably plan the location of the charging pile. 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 cable.
Second, use an automatically retractable or winding device. Some charging stations are equipped with an automatically retractable charging cable or a storage box. When the vehicle approaches, the cable can extend to an appropriate length and automatically retract after use to prevent the cable from being too long and scattered.
Third, use a charging station with an adaptive cable length. At present, Maruikel provides retractable charging cables. This type of charging station can automatically control the release length of the charging cable according to the actual use situation, thereby avoiding the above-mentioned problems caused by the excessive length of the cable.
Fourth, strengthen the management of the cable. Use cable clamps, straps or other fixing devices to manage the charging cable to avoid being dragged randomly and reduce wear and tear and tripping risks.
