How to use WunderCurrent Car Charger Extension
we’re taking a closer look at the Wundercurrent EV car charging extension reel, designed for safe and convenient charging anywhere, anytime like restaurants or dhaba on highway or home on offbeat location.
Why Earthing Matters?
Before we jump in, let’s understand why earthing is crucial for EV charging. Proper earthing, with a resistance of 5 ohms or less, is needed for charging EV; without it, the Electric car cannot be charged and is essential for safe charging. It ensures any leakage current is safely diverted to the ground, protecting you and your car from electrical hazards.
Using the Wundercurrent Extension Reel
- Plug the Wundercurrent extension reel into your main switch.
- Look for the earthing indicator light.
○ If the light is bright and steady, congratulations! Your building’s earthing seems good to go.
○ If the light is dim or off, Wundercurrent’s external earthing mechanism can help establish a proper connection.
External Earthing with the Wundercurrent Kit
- Grab the provided 5-meter earthing wire. It has a crocodile clip on one end and a banana plug on the other.
- Take the 6mm copper rod included in the kit. This rod has one sharpened end designed for easier insertion into the ground. Safety Tip: Find a clear area away from flammable objects or underground utilities before inserting the rod.
- Push the sharpened end of the copper rod at least 4 to 6 inches deep into the ground.
○ Ideally, aim for slightly deeper for better earthing. - Now, connect the crocodile clip on the earthing wire to the copper rod you just inserted.
- Finally, plug the banana plug on the other end of the wire into the earthing socket on the Wundercurrent reel.
Charging Your EV and Safety Reminder
Once you’ve confirmed or established proper earthing, you’re all set for safe and convenient charging! Simply plug your EV charger into the Wundercurrent socket and connect it to your car. Remember, for optimal performance and to avoid overheating issues, always unwind the entire extension cord before charging.
With the Wundercurrent’s easy-to-use external earthing kit, you can now charge your EV with peace of mind, anywhere, anytime you go.
Can I buy W2 for Nexon EV Fearless 45, why to buy W3?
*The main difference between the W2 Ultra/W2 frunk (2.5 sq mm 3 core cable) and the W3 Ultra/W3 frunk (4 sq mm 3 core cable) lies in their cross-sectional area.* The 4 sq mm cable has a larger cross-sectional area, allowing it to carry more current compared to the 2.5 sq mm cable. This difference is crucial for applications with higher power requirements.
Think of it like this:
● The *”sq mm”* (square millimeter) indicates the thickness of the cable, which determines its cross-sectional area.
● A thicker cable (like the *4 sq mm*), with its larger cross-sectional area, is like a wider highway for electricity. It can carry more electrical power (current) at once without struggling.
*Why the W3 Ultra/W3 frunk (4 sq mm) is often better for charging electric vehicles:*
● *Higher Power Capacity:* Electric vehicles, especially those with higher power requirements, draw a lot of electricity. The thicker 4 sq mm cable, with its larger cross-sectional area, can handle this higher power much more safely and efficiently.
● *Reduced Overheating Risk:* Carrying more power through a thinner cable can cause it to heat up. The larger 4 sq mm cable reduces this risk significantly, ensuring safer charging.
● *Efficient Power Transfer:* It ensures that your EV gets the power it needs smoothly and effectively, leading to more efficient charging.
In summary, the *W3 Ultra/W3 frunk (4 sq mm 3 core cable)* is preferable because its larger cross-sectional area allows it to carry more power safely and efficiently, making it a more robust choice for EV charging.
Dear sir plz conform its a power backup or extension wire coil only?
