Charging an EV? Don’t Use an Extension Cord

Extension cordsA lot of electric powered car companies supply a Stage 1 charging cord when you acquire an EV or a plug-in hybrid (PHEV). These “trickle chargers” really do not demand special tools to use and connect to a typical 120-volt electrical outlet at residence or elsewhere. The cable duration can assortment from 6 toes to 20 ft or a lot more depending on auto make and product.

If that charging cable is not very long ample to plug into a nearby outlet, you may well be tempted to use an extension twine. Here’s why you should not.

Why You Shouldn’t Demand an EV With an Extension Wire

Charging an EV involves extra electrical power than the amount of money common household appliances need to have. As a result, EV chargers include thicker wires that can deal with a lot more electrical power than scaled-down gauge wires in common extension cords.

“While some electrical automobile house owners have claimed using a usual extension wire, we never propose it,” claims Kelley Blue Book Government Editor Brian Moody. “In point, Kia and other automakers specially say not to use an extension twine in the owner’s handbook.

The chance of fire increases for the reason that the extension twine attempts to transmit extra electrical power than it was designed to carry. Overheating cords can melt plugs and receptacles, and the fireplace hazard is higher when remaining unattended overnight or while you’re not dwelling.

Yet another basic safety chance is electrical shock. An EV charging cable is additional risky when related to an extension twine. Rerouting the electrical power supply from your electrical outlet by way of an extension compromises the balance of this ability transfer. Inserting and eliminating the plug then results in being a riskier process.

How to Correctly Join a Stage 1 Charger
