Extension Cord

I've gone as low as 104volts with no problems

 

I've used a 100 foot 12 gauge extension cord many times without any problems.

 

it was in the "Attention Kill A Watt Nerds" thread

 

There are at least 3 reasons for Toyota's concern about using extension cords

1. Voltage drop over a long distance with too small a gauge cord, solved by using a 10 or 12 gauge cord
2. The cord before the "brick" (on the EVSE) is not ground fault protected, unless the outet you are using is, solved by using a GFCI outlet, but that coud be a potential liability lawsuit, if someone is electrocuted.
3. Tripping hazard. As the cord becomes longer, it could become a tripping hazard, so be careful of the route you place the cord in. Is it crossing a walkway? Potential lawsuit from someone tripping over it.

If you use common sense and are aware of the potential issues, there's no inherit problem with using an extension cord.

 

I just got a 25 foot 12 gauge extension cord as well. Slightly ogg-topic, but as the rain season is approaching in California, I want to find a waterproof bag to store the extension cord in the car, and also use it to cover the EVSE in the rain.

I know that EVSE itself is waterproof, but I figure extra protection wouldn't hurt. I can always use a grocery store or Home Depot plastic bag to wrap the EVSE; it is a bit ghetto

I looked at some "document bags" and tool-carrying bags, but they are sub-optimal for what I need.
Any recommendations for less than $20?

 

The voltage drop across the extension cord is caused by the cord resistance. A bigger wire has less resistance for the same length cord. The power dropped across the cord causes the cord to heat. This is lost energy. If cord heat is too high, the cord will be damaged and can start a fire. There is voltage drop across the whole charging cord, even without an extension. That is why Toyota asks us not to wrap up the cord, or cover it. A coiled cord cannot properly dissipate the heat. This same "do not wrap or cover" rule applies to the extension cord, too.

 

So is there a good but cheap source for these extension cords, or are you guys just getting them at the local Home Depot/Lowes store?

 

I used this one with no problems:

25' 12 Gauge Pink W Green Stripe Indoor/Outdoor Extension Cord with Lighted End | eBay

 

Don't stay in a Motel unless they allow you to plug in.

 

Thanks, this looks like a really good deal, and made in the USA as well (assuming they didn't make it in China and package it in the US).

 

YUKIT,

I've been using CordPro (the medium size). Search this site for CordPro. I uploaded pix of EVSE in its CordPro. Never a problem during use, very handy small-size cord management package and it actually fits in the hidey-hole slot under the cargo floor. Note: the portable EVSE blue handle has five (5) -point star security screws, which the user needs to undo/redo to use the CordPro to its designed capability - it's covered in the CordPro thread.

 

...of course, the CordPro will work very well for just an extension cord without any disassembly/reassembly of the cord. Nice not to have to deal with long tangles in the cargo compartment.

 

Bump....

Looking for a extension cord solution, suggestion. Any input would be greatly appreciated.

I have 2 extension cords already, one that is the same gauge and specs as the cord running from the CCID to plug, and 50 ft long. I can probably get by with 25-30 feet though. The other cord is a bit thicker, 12 gauge, and 100ft. Its one I already owned, but decided to buy the other cord to match the CCID wires and not have so much slack. Again 25-30 feet is all I need.

Here are some of my questions...

1. Is it better to go with the thicker wire to help ensure less currency is lost during travel? Does the thicker cable being 100 ft instead of 50 make a difference since the currency travels a longer distance? Should I buy a 12 gauge 30 footer?

2. What is the risk of using an extension cord; why doesn't toyota want you to do it?

3. Does the CCID need oxygen or anything like that? In case of sprinklers etc, I am thinking of altering a small storage bin to house the CCID and prong connector with the extension cord and EV cord coming out of opposite ends. The other option I was thinking is to put the CCID in the car with the EVC out the window. Any spot on the ground or driveway is going to get sprayed with water or have water running along it at some point as the driveway is elevated.

I figure with fear of theft and weather, someone must have made a device, or system of placing the CCID in the car so it cant get stolen etc. Hmm, maybe a tool box with a pad lock on it for public garages or something.

Thanks for reading.

Q 1. There is more resistance in a longer, thinner wire. I get by nicely with a 14 guage, 15 Ft extension.
If you have a meter, plug in the extension and see if there is voltage loss. Q2 there is a small hole on the depress handle portion, a lock can be inserted there. I guess you have to park outside so that becomes a problem. The charging cable (EVSE) does not need anymore oxygen than we do. Should you have some extra, it won't hurt to breathe on it once in a while, not too often, they get spoiled. That link that was given to you should help you out on securing cable. You can search the site for almost any related Prius subject.

 

Thanks for the extension cord info.

I was thinking more of waterproofing/overheating than theft protection with the oxygen question. As much oxygen as we do? I was going to secure it in a moderately air tight plastic container. Something I definitely wouldn't lock myself in for a very long time...
