Picture of DIY carbon tape heated vest
diy heated clothing kit

The pattern made from some factory vest.
6 meters of carbon heating flex tape (www.carbonheater.us) placed on back and both sides. By touch carbon is a little bit like a loose weave silk. It's very soft but strong enough.
Because of big length it provides uniform heating of body.

Tape connected in parallel 6x1m. It takes about 3A under 12V (36W).

Step 4:

You can sew wire to carbon tape to make a good and flexible connection.  The contact place shouldn't be hotter than the tape itself. If not you must increase the contact area. The best idea to place wire between two layers of carbon tape.

Step 5:

Contacts may be sewed by sewing machine or just wraped with a wire.
But as you can see sewed contact is colder than the tape itself (left contact).
Wraped contact (on the right) is more hotter than tape.

Step 6:

Carbon tape can be extended.
Place two pieces of carbon tape together on each other with little overlap and sew it on.
As you can see the connection place is not hotter than the tape itself.

Step 7:

P3300057.JPG
Sewed contact very flexible.

Step 8:

It's powered by 6x18650 connected in parallel (2x3).
I use it with an adjustable controller.

With a half power. I use it with my heated gloves and insoles.

I like this. Have you tried snap buttons instead? That way you can disconnect the connections.
Shenzhen (author)  NWBrewer1 year ago
You can see the battery connector and a power button the same as placed inside right there.

Can you wash it?
Shenzhen (author)  NWBrewer1 year ago
Yes, I can wash it without any problem.

excellent project...what width tape are you using here?

Shenzhen (author)  hairyogre9 days ago

15 mm.

can a 3s 2200mah lipo pack be used as power source and do i need a protective circuit? (due to the nature of the lipo packs, they are tend to burn or bubble)

Shenzhen (author)  Bülentİ22 days ago

That pack has about 20-25 Watt of power. It's not much but of course you can use it.

Protective is very usefull and recommemded.

Do you have a sketch of the electrical connections on the vest, I am not clear as to how this is wired, it appears that the wiring is connected in multiple spots on one continuous ribbon....
Shenzhen (author)  Navy_Chief1 year ago
The tape is divided into 6 equal parts1 meter of each. Parts are wired  to obtain 6 parts in  parallel. The first figure below shows the wiring on the vest. The second figure shows the equivalent circuit.

2 questions on this. In step 7, the positive and negative connections appear to be in the same location at the top of the vest. Are the connections isolated from each other right there? Also, the 6 - 1 meter sections... Are they separated, or is it a continuous strip with power connections in the middle? Thank you.
Shenzhen (author)  locozap23 days ago

Yes, it's a continuous strip with power connections in the middle.

It is just one connect with two wires. Sorry about different colors.

This looks awesome. I have a quick question about safety:

How do you insulate the tape?

Can you touch the tape when power is connected?

Shenzhen (author)  mnørgaard24 days ago

Yes, you can touch it when powered because of low temperature and voltage.

I insulate it with a thick fabric only.

What makes this carbon fiber tape resistant? Is it different than other carbon fiber fabrics I can find? The one I tried from the local shop barely generated heat.

I was thinking about making some glove liners and using the removable liner in my riding jacket for this project. But I'd like to know if I connect the gloves at the sleeves of the jacket and have power coming into the bottom of the jacket from the motorcycle if it would work. Or should I have a separate power source for the gloves? And lastly, is the 12 volt power for the bike to much power?

Shenzhen (author)  paul.barber.904751 month ago

Yes, the 12 volt power supply is very convenient for gloves. Separate connection is not required. Connect gloves to sleeves. I think that will be enough 10 watts for each glove, it is not much of power for a bike battery.

Shenzhen Hi, tell me what you used to do the tire warmer to motorcycle tires, carbon fiber, the same material or something else? I need 80 degrees http://www.risingsuncycles.com/images/tirewarmers/TwarmFrnt.jpg

Shenzhen (author)  adam.walicht1 month ago

Dear Adam,

Yes, the same.

Carbon tape better than other heaters if needed flexibility, resistance to repeated bending, uniform heating of a large area. So it's also used in a good quality steer weel heated covers.

Thank you for a fresh idea. We offer you a discount of 20% for you first order on www.carbonheater.us

Do you have a special circuit or recommendation for charging the battery pack?
Shenzhen (author)  elubbers2 months ago

Wow this is great!!

How much power will I need to keep water from freezing in a hose? the fabric dimensions would be 88.9cm x 35mm. I want the battery to be as light as possible also

Shenzhen (author)  leviwilner11 months ago
1. Water temperature?
2. Pipe diameter?
3. Water speed?
4. Air temperature?
5. Air speed?
6. Is it possible to cover carbon tape with some insulation?

1. ~4.4C

2. 6mm inside diameter

3. same as drinking though a straw

4. ~ -7C

5. 0

6. yes there would be insulation over the tape.

Shenzhen (author)  leviwilner11 months ago

Depend on insulation quality and thickness it will be enouph one piece of 90 cm 44 mm carbon tape at 3,7v.

I just received that material (from you?) I ordered online and it came from Russia. I am ready for try things. Would you, please, show the calculations for this example (90cmx44mm @ 3.7v)? Thanks

Shenzhen (author)  macinissa.mezache2 months ago

It's about 8 Ohm/m, so for 90cm it's 7,2 Ohm.

3,7v : 7,2Ohm =~0,5Amper

The temperature depends on current only. I've made a table current/temperature. As you can see it starts from 0,92Amper (39,3 Celsius). I think at 0,5A you'll get less than 30 Celsius. To increase the temperature you should increase the voltage or decrease the tape length.

Great Thanks!

Are you able to cut the tape down the center of the width making thiner tape?

Shenzhen (author)  MrJack20012 months ago

No.

how fast does this warm up and to what temperature? more specifically how fast does a 12" length of the carbon tape heat up?

Shenzhen (author)  SideTracked3502 months ago
If the tape is closed with a heat insulator, it will heat up for 1 second. If the tape is not closed and it the cold wind blows, it will not warm up to the maximum temperature. The heating time will depend on the temperature and wind. Carbon tape - this is the usual heating element. It works in exactly the same way as all other heating elements. Its main advantage is the flexibility. Carbon tape is not afraid to repeated bending, so it is suitable only for clothes.

The temperature depends on the current. Select the current to the desired temperature in the table.

May have always been answered, how long does the battery pack last before charge is drained?
Grrr make that, May have already been answered,
Shenzhen (author)  dad_a_monk9 months ago
Before batteries run, approximately 1.5 hours.
Now I use rf dimmer and battery runs 3-5 hours, bacause I can choose the power in accordance with the ambient temperature:

What prevents overheating. And fire
Shenzhen (author)  breszler10 months ago
Just like any other heater, the carbon tape can be heated in a wide temperature range. As well as using, e.g. nichrome heating wire shortcut circuit can result in a considerable overheating and even fire. Any heating appliance must comply with the terms of use. Naturally, this requires a basic knowledge and experience.
First you need to calculate the correct length of the tape. It depends on the desired temperature, heating area and planned voltage.

Hey guys, for the battery pack , i found a cool AA battery holder so you can make your own sort of. Looks pretty nice. I plan on useing it if i make a vest like this.
