Electricity is everywhere, and could theoretically power electric cars anywhere we wish to go. But recharging an electric car requires a charging station, and the vast majority of places lack charging stations. Using extension cords, power adapters, and a portable charging station can help you charge through a regular power outlet.
Or maybe there is a charging station, but another car or truck is blocking access. If the owner of the blocking vehicle cannot be found, are you stuck? Not if you carry a J1772 extension cord, which lets you extend the reach of the charging station. Simply park in a nearby spot, and run the J1772 extension cord to the charging station.
Since electricity is everywhere, it would be terribly convenient to be able to recharge the car anywhere we go. With appropriate adapters and extension cords we can recharge an electric car at places that do not have electric car charging stations.
To do this safely means developing knowledge of some simple rules for safely using extension cords and adapter cables. You must be able to recognize the various power outlets, understanding the power limits available through each, and carry a high power portable charging station along with necessary adapters.
See: Informal electric car charging at any power outlet, versus a regular charging station
LANGUAGE NOTE: It seems that in some countries the phrase "extension lead" is used, and seems to mean the same thing as "extension cord".
SAFETY: Wait, isn't it dangerous to use an extension cord to charge a vehicle?
- Is it safe to use extension cords and adapters to charge an electric car? Yes, with care.
- Can you charge an electric car from a dryer outlet? Yes, with care.
- Are there any problems with charging an electric car using an extension cord? There can be, but all problems are solvable.
The short answer is to use a good quality extension cord with thick wires and beefy plugs, along with good quality power outlet. In the lists below we show several choices for 120 volt 10 gauge extension cords that are safe for use with a line cord charger, and several 240 volt 40 amp extension cords safe for use with higher power charging stations. The safest choice is a good quality J1772 extension cord, and we show a couple of those.
WARNING: Vehicle manufacturers universally warn against using an extension cord to extend the reach of the supplied line-cord charger. Please, exercise caution in reading what is written here.
The general principles are:
- Check carefully the power socket rating
- Check carefully the wiring to the power socket
- Use heavy duty cables with high enough gauge to handle the current
- Don't use cables that are frayed or broken
- If you can, adjust the vehicle charger to not draw more current than you know is safe
- Your power is limited by the weakest link in the chain - don't draw more through a circuit than the rating of the weakest component
- Check whether cords or connections get hot while in use
- Use the shortest length of cord possible
A skinny cord, frayed wiring, bad power socket, acts like a "resistor" or "heating element". Sending too much current through a bad connection acts like a heater. Say your car is pulling 6 kilowatts, a 10% loss from a bad connection means 600 watts being dissipated as heat. That's about the same as a typical hair dryer.
The heat generated by a bad power connection is a common cause of electrical fires.
Ampacity is the measure of the maximum safe current (amps) we can use in a wire of a given thickness. Generally, the thicker the wire the more current it can carry. See: Electric car charging within electrical code and power outlet limits
Smart electricians and electrical engineers have spent decades cooperatively developing the electrical code. Their recommendations were won through hard work and the occasional electrical fire.
I am offering this for education, and you are responsible for your actions. Applied incorrectly this can cause electrocution or fire. Take care, be smart and educated, and you'll be okay.
Done badly, it's possible to cause damage. The warning against extension cords isn't a whimsy, they're rightfully concerned about safety. There have been multiple fires from electric cars being charged through substandard wiring. Careful use of good quality extension cords and power outlets is the way to avoid an electrical fire.
Why does this page say an extension cord is okay when the manufacturers say NO?
The manufacturers are excercising caution, and are afraid of liability. An electric car charging-related electrical fire can set back EV adoption, and hurt the reputation of the manufacturer associated with the fire. An over-abundance of caution is a good thing when there is risk of an electrical fire, and we do not fault the manufacturers for being cautious.
At the same time, with knowledge one can do things manufacturers warn against doing. The safest method is the J1772 extension cords discussed later.
There is a voltage drop that increases as the charging cable gets longer. The lowered voltage causes issues with the charging equipment that can lead to problems. The two solutions to the voltage drop is to use thicker wires, and to keep the cables as short as possible.
To most of us the natural way to use an "extension cord" is to plug it into a power outlet, then one or more gizmo's plugged into the cord. We do this all the time with christmas lights, clothes irons, radios, computers, televisions, etc.
With electric car charging we have two choices of using an extension cord. The picture above demonstrates these choices:
- We can plug the electric car charging station directly into a wall outlet, and then use a J1772 extension cord to reach the car.
- We can plug a regular extension cord into the wall outlet, then plug the electric car charging station into the extension cord.
Of the two, the safest is the J1772 extension cord. A good quality J1772 extension cord is built to handle the charging current without problem, where the regular extension cord might be suboptimal.
TL;DR What is the right cord to charge an electric car?
That was a lot of information, so lets boil it down a little.
From a pure technical standpoint a good quality J1772 extension cord is the best choice. You know it will handle the current and won't be the cause of an electrical fire.
But your budget may not be enough for the cost, and therefore a regular extension cord may be preferable. If so, choose based on the power outlet(s) you'll be using and the charging rate you'll need. The NEMA 14-50 or 6-50 cords are the safest if appropriate for the conditions you'll be facing. If, like in the image below taken at Lucious Garage, you frequently use a lower power outlet like a NEMA L6-20, an extension cord matching that outlet can be very useful.
How to use an extension cord to charge a Tesla or other electric car
After having gone through all the safety warnings in the previous section, let's look at practicality.
Every electric car is sold with a "line cord charging station". In most cases this charger is low power - for example in the USA they typically support 120 volt charging. But this is one area where Tesla and a couple other electric car makers shine.
Every Tesla is sold with the Universal Mobile Connector that supports both 120 volt charging, and 6 kiloWatt charging through a NEMA 14-50 connector. Plus, Tesla sells a kit of adapters for all kinds of other power outlets. With those adapters the UMC automatically adjusts the charging rate to match the power adapter. Every Tesla owner should get the kit of adapters, and, for certain locations requiring an extension cord, get one that matches the power plug used at that destination.
For owners of other electric cars it is useful to examine the Which End to Extend section above. We have a choice between using a J1772 extension cord, or a regular extension cord. It is probably safer to use the J1772 extension cord though more expensive.
The first step is selecting a mobile charging station. In most cases the charger supplied with the car only supports 120 volt charging, but one might want a faster unit. A few of the manufacturers are now supplying more powerful charging stations with the car. There are several portable charging stations for electric cars to choose from.
Putting these parts to use is fairly easy. If using a J1772 extension cord, plug it into the car then plug your charging station into the other end of the J1772 extension, then plug the charging station into a power outlet. If using a regular extension cord, plug it into the power outlet, then plug the charging station into the extension cord, then plug the charging station into the car.
The final step is ensuring the charging rate is within the limit imposed by the power outlet. If you've plugged-in to a NEMA 6-20 outlet, you're limited to a 16 amp charging rate at 240 volts. The car had better know to limit itself appropriately or the circuit breaker will pop. Some electric cars let you adjust the charging rate as a setting in the infotainment system. Some of the portable charging stations support setting the charging rate.
It's useful to learn to recognize different power outlets and their ratings. See Electric car charging within electrical code and power outlet limits
This is an example of the plan in use. The location is Lucious Garage, a car repair shop located in San Francisco which specializes in hybrid cars. This garage kindly makes its space available for Golden Gate Electric Vehicle Association (GGEVA) meetings every month, and allows GGEVA members to charge their cars for free during meetings. In this case a NEMA L6-20 to NEMA 14-50 adapter is being used to access a power outlet installed on the car lift. The charging station is plugged into this adapter, and then the charging station is instructed to limit to a 16 amp charge rate. The car, a Kia Soul EV, does not allow the user to set the charging rate manually.
Product Index
J1772 electric car extension cords can be the best choice
The best electric car extension cord may be one between the J1772 plug from the charging station to the J1772 socket on your car. J1772 cords are usually built with heavy-duty wire and components meant to carry the current required to charge an electric car. It should be much safer than plugging into a dodgy power outlet with a skinny frayed cord that can cause an electrical fire.
Some considerations that will separate the good quality J1772 cords from the bad:
Ratings: As with every other component in the charging system, the J1772 extension cord must be rated to handle the current required for the charging rate. For a 6+ kiloWatt charging session, the cord needs to be rated for at least 40 amps.
| EVSE type | Range per hour of charging |
Power required | Circuit |
|---|---|---|---|
| Typical line charger | 4 miles | 120 volts 12 amps | 120 volts 20 amps |
| 3 kW EVSE | 10-12 miles | 240 volts 16 amps | 240 volts 20 amps |
| 4-5 kW EVSE | 18 miles | 240 volts 24 amps | 240 volts 30 amps |
| 6 kW EVSE | 20-25 miles | 240 volts 32 amps | 240 volts 40 amps |
Wire size: To be useful, a J1772 extension cord has to be 25 feet or longer, which can mean a significant voltage drop with thin wires. For a 6+ kiloWatt charging session, the wires should be 8 gauge or thicker.
Flexibility: Your J1772 extension cord will be used in a variety of settings, so a flexible cord is a must.
JLONG - 40 Amp, 40ft, J1772 extension cable
The JLong is perhaps the best J1772 extension cable available. The 40 foot length means it can get you out of more sticky situations than other shorter cords. That it is rated for 40 amps peak it can handle a full 32 amps continuous. The components are all solid and well-built. The J1772 handle includes a little hole allowing you to add a lock (that is included) for a touch of safety.
EV Everything 20 ft Extension Cord J1772 Cable 32 amp Electric Vehicle Charging
The EV Everything J1772 extension cable has a 20 foot length that will be useful in some cases, but other makers supply longer cords making them more useful. The product description says it supports 32 amps, but does not make clear whether this means 32 amps continuous. It may mean it supports 32 amps peak, in which case it would be limited to 24 amps continuous. It is unclear why this would come with a charging cord holster since the purpose is to bring it with you.
50 AMP J1772 25’ Extension Cable (UL Approved)
The TeslaTap J1772 extension cord is rated for 50 amps, or quite a bit more than the competing cords. As a J1772 extension cord, it has J1772 connectors on each end. It passes through all control signals so that safety protocols are obeyed at both ends.- Rated for 50 amps
