Tesla installs exploding dye sleeves at Superchargers to prevent cable theft [Update]

Tesla has started installing a new anti-theft device at Supercharger stations in the United States to help prevent, and hopefully put a stop to the problem of Supercharger cables being cut.

For years Tesla has had to deal with thieves cutting Supercharger cables at stations around the world. While isolated when considering the expansive global Supercharger network, the theft and vandalism can be problematic in areas prone to the crime, sometimes with stations being hit multiple times in a matter of weeks. We have previously reported that entire Supercharger stations can be shut down after all the cables were cut, rendering the station useless.

Thanks to Tesla’s responsive Supercharger service team, the cables are often quickly replaced, causing minimal disruption to owners. However, each time it happens it is an extra, and unnecessary expense for the company.

Now Tesla is taking a novel approach to help combat the problem. First spotted at a new Supercharger station in Seattle, Washington, the company has started installing a device to prevent the cables from being cut.

Called DyeDefender, the device is a stainless steel hose barrier filled with pressurized, blue-staining dye that explodes when someone attempts to cut the cable. Here is what the device looks like installed on a Supercharger cable. (via Reddit)

And here’s what happens when someone attempts to cut the DyeDefender.

So far this is the first instance we have seen Tesla installing these new devices. Presumably this station has been the subject of cable theft before, and the company might be using this as a test site before expanding it to other stations in high-crime areas.

UPDATE 1:40pm PT: Max de Zegher, Tesla’s Charging Director, told us this DyeDefender site is a trial and the company is exploring anti-theft options. Addtionally, “Property of Tesla” is now being engraved on the copper cables to alert recycling companies not to accept them and contact Tesla.

Just a trial. We're always exploring options. Supercharger cables will also have "Property of Tesla" engraved from our Buffalo NY factory, so recycling companies shouldn't accept them and notify us. It's a scalable, cost-effective solution that doesn't impact service operations &… pic.twitter.com/pktFK4hXcD
