The configuration of the length of the ev charging cables needs to be based on a variety of factors, including the location of the charging point, the parking location of the vehicle, safety, efficiency and cost.
The unreasonable configuration and use of the ev charging cables often brings a series of problems. These problems mainly involve safety, efficiency and economy:
❶ Electrical safety:
Excessively long ev charging cables increase the risk of short circuits and insulation failures, especially in outdoor environments where the charging cables may be affected by weather factors (such as rain and high temperatures).
❷ Mechanical damage:
After the owner uses the cables for charging, it may be scattered on the ground and easily crushed by passing vehicles, causing the outer insulation layer of the ev charging cables to be damaged, increasing the risk of leakage and electric shock.
❸ Efficiency and performance:
Mainly reflected in power loss. According to Ohm's law, when current flows through a conductor, heat is generated, that is, energy loss caused by resistance. This means that the longer the cables, the greater the resistance, the greater the power loss, which will lead to a decrease in charging efficiency to a certain extent.
❹ Charging speed:
Due to power loss, ev charging cables that is too long may cause the actual voltage reaching the battery to decrease, thereby affecting the charging speed and prolonging the charging time.
❺ Waste of power resources:
Due to power loss, part of the electrical energy is converted into heat energy and dissipated, which not only increases the charging cost, but also wastes power resources.
❻ Maintenance cost: Overlong charging cables are more susceptible to damage and require frequent inspection and maintenance, which increases maintenance costs.
❼ User experience: The overly long ev charging cables requires additional organization and management during use, which may cause inconvenience, and the scattered gun cable will also affect the cleanliness of the environment.
In summary, the longer the cables length of the charging pile is not, the better. When planning the charging pile, the charging pile should be as close to the parking space as possible to reduce the cables length. At the same time, it is also necessary to ensure that its length is flexible enough to meet the charging needs of different vehicles.
Under normal circumstances, a 3-5meter charging cables length is sufficient and can maintain good charging efficiency and safety. If you need to cover a longer distance, you can consider adding charging piles or optimizing the overall layout of the charging point.
