Question 21

What is a Tethered or Untethered EV Charger?

Accepted Answer

A tethered EV charger and an untethered EV charger refer to two different types of electric vehicle charging stations, specifically regarding the connection between the charging cable and the charging unit itself. Here's an explanation of each:

 	Tethered EV Charger:A tethered EV charger, also known as an integrated or fixed cable charger, comes with a permanently attached charging cable. This means that the cable is physically connected to the charging station or wall-mounted unit and cannot be detached. To charge your electric vehicle, you simply plug the other end of the tethered cable into your vehicle's charging port.


 	Untethered EV Charger:An untethered EV charger, also known as a socketed charger or universal charger, does not have a permanently attached charging cable. Instead, it has a socket or receptacle where you can plug in different charging cables. To charge your electric vehicle, you need to provide your own charging cable, which typically comes with your vehicle. You plug one end of the cable into the charger's socket and the other end into your vehicle's charging port.

Question 22

How do I charge instantly from my EV Charger?

Plug and Charge:Simply plug the charging cable into your EV to start charging. To stop charging, use your car to unlock the charger cable from the EV and unplug.


 	RFID Card:Alternatively, activate the charger from the unit by swiping the RFID card over the reader indicator. To stop charging, simply swipe over the reader indicator again. A yellow pulse indicates a successful card swipe.

Question 23

How long is the cable on a tethered unit of my EV charger?

Accepted Answer

If your electric vehicle (EV) charger specifies that it has two cable options of 4 meters (approximately 13 feet) and 7 meters (approximately 23 feet), then you have a choice between these two cable lengths for the tethered unit of your EV charger. You can select the cable length that best suits your charging needs and the proximity of your charging port to your vehicle's parking location. When determining the suitable cable length for your electric vehicle (EV) charger, it's essential to consider 'usable' length of the cable. The 'usable' length refers to the length of the cable that can comfortably reach your vehicle's charging port without being pulled tight in the air or creating excessive tension.

In practice, it's advisable to select a cable length that ensures the cable comfortably trails on the ground rather than being stretched tightly in the air. This not only prevents unnecessary strain on the cable but also reduces the risk of wear and tear over time.

Question 24

My EV charger is no longer online, preventing me from establishing a connection. How should I proceed?

Accepted Answer

You should start by resetting the charger. To do this, simply power the unit down for at least 10 seconds and then switch the power back on. Once you've done this, the unit will reboot and should come back online within 5-6 minutes. If you've tried this and are still experiencing issues with connectivity, please contact our support team for remote assistance, as this could potentially be related to a software issue.
