EV charging cable theft: how to protect your cable

The right protection against EV charging cable theft depends first on when the cable is exposed. A connector locked during charging, a connector stored on the wall and a cable left out in a car park do not carry the same risk. Before buying a lock, work out what you want to prevent: the connector being pulled out, a portable cable being taken away, or the cable being cut.

1. Identify your cable and your situation

Start by distinguishing a portable (detachable) cable, which unplugs from both the car and the charger, from a cable permanently attached to a wallbox. The first can be taken along for charging away from home; the second stays with the installation when the vehicle leaves. This difference changes your storage routine and the choice of accessory.

Next, note the connector format. Type 2, Type 1/J1772, CCS and NACS are not interchangeable. A lock designed for a specific adapter cannot be considered compatible with every connector. Also note the cable brand and take a photo of the handle: two connectors of the same standard can have different outer housings.

Finally, look at the real environment. A closed garage, a carport open to the street and a shared car park do not offer the same access opportunities. Does the cable stay outside all night? Can someone approach the charger without being seen from the building? Who uses the equipment? These answers are more useful for choosing protection than a general promise of a “universal” lock.

2. Check the locking during charging

Read your vehicle manual to understand when the connector is held in place and when it is released. The behaviour can depend on the model, the settings and the state of the session. For the vehicles covered in its guide, Volvo states that the cable locks once fully inserted (page in French). This example is not a guarantee of how every car works.

Also check retention at the charger end if you use your own cable. The fact that the connector is locked at the car end does not necessarily tell you anything about the other end. Carry out this check during normal use, following the manuals, without pulling hard or trying to bypass the mechanism.

An accessory added around the connector must neither prevent it from being fully inserted nor stop charging from ending normally. Do not improvise a padlock in an area not designed for it. If in doubt, ask the manufacturer to confirm which accessory is compatible with the exact model.

3. Secure the cable between sessions

A portable cable that is no longer in use can be stored in a closed space. A bag such as Proctelec Carry makes it easier to transport and keep organised in the boot; the bag itself is not an anti-theft device. The point is to make storage easy, so that the cable does not stay outside out of convenience.

If your setup requires keeping the connector close to the charger, a lockable holder can limit opportunistic removal. Dock Code, a Type 2 holder with a mechanical combination lock, combines cable storage with retention of the connector at rest. Check the shape of your handle and the quality of the mounting wall.

The code should remain restricted to authorised users. In a shared garage, decide who can change it and how to give access to a new person. A device whose code stays displayed on the wall loses much of its value. Conversely, an overly complicated arrangement may discourage everyday use.

4. Compare functions, not just names

The Tether can be considered as supplementary retention where suitable anchor points exist. Never tighten a device around the electrical cable to the point of deforming it. For a J1772 adapter, review the Lock J product page and its exact configuration before choosing it.

5. Treat the risk of cutting separately

Retaining the connector does not prevent an attack along the length of the cable. If your car park has seen repeated attempts or leaves cables permanently accessible, the question becomes one of a mechanical barrier around the cable, site surveillance and how maintenance is organised.

A CatStrap EV Cable Shield configuration is prepared using the charger models, cable lengths and diameters, plus photos of the cable outlets. Supply and lead time must be confirmed in a quote. No protection makes theft impossible: you must still be able to inspect the equipment and handle it normally.

6. Set up a routine that is easy to keep

1. Before plugging in, look at the visible condition of the cable and connector.
2. Only use the configuration approved by the manufacturers.
3. At the end of the session, stop charging normally before unplugging.
4. Store the cable in loose loops, without trapping it under a door.
5. Lock the holder or put the cable back in the closed space provided.

Avoid driving over the cable to block it or trapping it under a heavy object. Theft protection must not create a risk of damage. A clear route, a practical storage height and a code known only to the right people encourage regular use.

If the cable disappears or appears to be cut

Do not reconnect damaged equipment to see whether it still works. At a public charger, notify the operator shown on the equipment. For a private installation, have the equipment checked by a professional before putting it back into service. Collect information for your report only if you can do so without approaching a dangerous part.
