EV cable is the charging cable that will be used to charge the Electric Vehicle. Every electric vehicle comes with a set of charging cables. The cable has a 3-pin plug at one end for domestic plugs and at the other end, there’s the correct plug according to the requirement of the Electric Car.
However, for charging at public charge-points, another cable will be required with an appropriate plug; often companies provide both sets of cables with their electric car, but in case there’s a single domestic cable, the owner can buy the cable for public charging-points from the manufacturer or third-party retailers.
Single-Phase and three-phase EV charging cables:
Standard power sockets at homes and residential buildings supply single-phase power supply, whereas, normal public charging devices and commercial buildings supply three-phase power. The two power supplies differ as of the three-phase circuit supply power to the electric vehicle through two additional wires, L2 and L3 and thus charge three times faster.
Auto-switching charging cable is readily available that have been optimised to facilitate both single and three-phase power supply. Hence, a 3-phase cable can be plugged in a single-phase charging point and likewise, a single-phase cable will be safe to be used at a public charging point.
Types of EV Changing Plugs:
There is no universal plug or socket for all-electric vehicles and they vary with the manufacturer and charging standards of the vehicle. Usually, there are two types of sockets on the vehicle-side; Type 1 and Type 2.
Type 1 charging cable is mainly the standard of Asian, American and Japanese car models whereas in Europe Type 2 inlet is the standard. Type 1 cables come with single-phase plugs that allow up to 7.4 kW (230 V, 32 A) charging power levels. Whereas Type 2 cables have triple-phase plugs that offer up to 22kW charging power levels. Public charging stations in Europe are mostly equipped with Type 2 sockets and allow up to 43 kW (400 V, 63 A) of charging power levels.
Characteristics of EV Charging Cables:
Regardless of the manufacturer or plug type, following are the essential characteristics that every EV charging cable should possess because these cables are accessible to the public, and therefore demand extra precaution.
- Ensure fool-proof security
- Is multi-standard certified
- Easy to use
- Is flame retardant
- Offer high flexibility at extremely high and low temperatures
- Cable has a thin diameter and is lightweight
- It prevents leakage
- Comes with PVC insulation and jacketing
Model of the car and strength of the in-built charger of the Electric Vehicle determine which EV charging cable will be appropriate for the car.
