The electric car charging cables connect the charging device to the EV charging infrastructure, allowing sufficient energy to be transmitted to the car's battery, and are comprised of signal lines, control lines, power supply auxiliary lines, and standard insulation.
For electric vehicle (EV) owners, comprehending the fundamental characteristics and safety precautions for establishing secure connections during EV charging becomes crucial.
Through this piece, you will acquire a solid understanding of EV charging cables and get detailed guidance on configuring a charging process that is swift, efficient, and risk-free.
Characteristics of Electric Vehicle Charging Cables
A. Length and flexibility:
The Length of an EV charging cord is a crucial consideration. Thanks to longer cables (up to 8m), you can efficiently charge your BMW i3, Tesla Model S, X, or Kia Soul EV from a greater distance. Long and flexible coiled cables are especially useful for limited parking spaces near public charging outlets.
B. Current rating and ampacity:
The greatest current that a charging EV cable can safely withstand depends on its ampacity and current rating (16A, 32A). Faster charging is possible with higher ampacity cables, but matching the cable's rating to your EV's charging capacity is critical. Mismatch can result in overheating, damage to the cable or charging plug, or even pose a safety risk.
C. Voltage rating and compatibility:
EV charging cables are made to accommodate various voltage levels. For Level 2 charging, 240 volts is the optimal voltage for faster charging. To choose the proper charging cable, you must first confirm the precise voltage requirements for your EV. Using a cable with an incompatible voltage rating can result in charging issues or even damage.
D. Plug types and connectors:
EV charging cables exist with various connector configurations to accommodate several charging standards. Below are some common plug types and their applications:
Type 1 (SAE J1772): This plug type is popular among North Americans and suitable for most electric and plug-in hybrid cars. It offers secure and dependable charging as recommended by various manufacturers.
Type 2 (IEC 62196): Type 2 connectors are now popular in the US after getting traction in Europe. They offer flexibility and convenience since they support AC and DC charging and are compatible with numerous EV models.
CHAdeMO: This special connector type enables high-speed DC charging and is mostly adopted by Japanese automakers. Fast-charging stations have CHAdeMO connectors, allowing brisk and effective charging sessions.
Combined Charging System (CCS): CCS has emerged as the prevailing industry standard for DC fast charging, seamlessly integrating the exclusive features of Type 1 and Type 2 connectors with an additional two-pin connector. This innovative design empowers compatible EVs to engage in high-speed charging capabilities.
E. Cable insulation and protection:
An EV charging cable must include standardized insulation and protective layers to be durable and safe. Look for cables with sturdy insulation materials to survive abrasion, severe temperatures, and probable exposure to chemicals or liquids. Reliable insulation guarantees top performance and lowers the chance of electrical risks.
F. Weather resistance and durability:
Since EV charging frequently occurs outside, it's critical to consider the charging cable's weather resistance and endurance. Select cables made of UV- and weatherproof materials to enable reliable charging even in challenging ambient situations. A sturdy EV cable will survive time and offer a dependable, long-lasting charging solution.
Precautions for Electric Vehicle Charging Cables
A. Proper handling and storage:
Careful cable handling is critical to guarantee long-term operation. The wire strain is directly related to dragging the cord or applying too much force. Ensure to tightly wrap the cable without any kinks or knots when not in use. The cable will stay in top shape for many charging sessions thanks to this procedure, which also helps to prevent cracks.
B. Avoiding cable damage:
Take the following steps to safeguard your charging cable from likely damage:
Avoid sharp bends and kinks: Excessive bending or twisting might weaken the cable's interior copper conductors, resulting in complex electrical or charging issues. Avoid using sharp angles when inserting or retracting the charging cable; instead, go carefully.
Prevent overheating and overloading: Charging cables possess precise ampacity ratings to prevent overheating and overloading.
Exceeding the current rating (A) is dangerous since it can cause overheating and damage to both the cable and the charging apparatus, so check the manufacturer's specifications to operate within safe parameters.
Protection against physical damage: Ensure the charging cable is not physically affected, and always use the EV cable away from anything sharp or heavy that could be puncturing it. Inspect the cable frequently for indications of wear and tear, such as fraying or exposed wires.
C. Ensuring compatibility with charging stations:
Before connecting to the EV charging station, ensure the cable is 100% compatible with the plug type and connector available. Using an incompatible cable can result in an unstable connection or possible damage to the EV charger.
Always familiarise yourself with the various plug types and connectors listed above to confirm compatibility.
D. Regular inspection and maintenance:
Regular inspection of the charging cable is essential to ensure EV owners' safety and the proper functioning of the cord. We recommend closely scrutinizing the following areas:
Checking for wear and tear: Regularly inspect the cable for any wear and tear, including cracks, cuts, or exposed wires. Should any damage be found during the examination, replace the cable immediately to prevent potential hazards.
Verifying connector integrity: Examine the connectors to look for signs of wear or damage. To ensure the cable and the charging port are working properly, clean the connectors frequently using a soft cloth.
Testing for electrical continuity: If the issue persists, seek the advice of a licensed EV cable expert or check the charging cable's electrical continuity with a cable tester tool.
Safety Measures during the charging process
A. Following manufacturer instructions:
Always heed the manufacturer's instructions for your electric vehicle (EV) and the charging apparatus. It also entails following manufacturer-recommended protocols, properly utilizing cables and connectors, and abiding by the rules for safe charging procedures.
B. Using dedicated circuits and outlets:
Always use dedicated circuits and outlets (120V or 240V) built exclusively for EV charging when charging your electric vehicle (EV). Avoid using extension cords and sharing circuits with other high-power appliances to avoid overload and minimize the risk of accidents.
C. Avoiding water and moisture exposure:
The charging outlet and cable must be moisture-free to avoid electrocution or equipment damage. Avoid touching the charging wire or equipment with moist hands and charging in damp environments.
D. Don't Run Charger Cable under Rugs or Carpet:
Running the charging cable beneath rugs or room carpets causes a tripping hazard and may damage the cable. Keep the cable open and easily accessible when charging to prevent risk.
