Is the charging gun extension cord safe?

The charging gun extension cord is safe to use under certain conditions, but the following points should be noted:


Electrical safety issues: Overlong charging gun extension cords increase the risk of short circuits and insulation failures, especially in outdoor environments, where they may be affected by weather factors such as rain and high temperatures.


Mechanical damage issues: Overlong charging gun extension cords are prone to scattering on the ground after use and may be crushed by passing vehicles, causing insulation damage and increasing the risk of leakage and electric shock.


Power loss issues: According to Ohm's law, when current passes through a wire, heat is generated, resulting in power loss. The increase in the length of the extension cord will increase resistance and power loss, thereby affecting charging efficiency.


Charging speed issues: Power loss will cause the actual voltage reaching the battery to decrease, thereby affecting the charging speed and extending the charging time.


Power resource waste: Part of the electrical energy is converted into heat energy and dissipated, increasing the charging cost and waste of power resources.


Maintenance cost issues: Overlong charging gun extension cords are more easily damaged and require frequent inspection and maintenance, increasing maintenance costs.


Safety tips

‌Choose reliable extension cords‌: Ensure that the quality and insulation performance of the extension cords meet the standards to reduce the risk of electrical failure and leakage.

‌Avoid using them for too long‌: Try to choose shorter extension cords, usually no longer than 5 meters, to reduce power loss and safety hazards.

‌Regular inspection‌: Regularly check the wear of the extension cords and replace aging or damaged cables in time.

‌Reasonable use and maintenance‌: Ensure that the extension cords of the charging guns will not trip or be crushed by vehicles during use, and keep the environment clean.
