Copper Theft at Charging Stations Is on the Rise
Public EV charging stations are facing an increasing problem—copper theft. Thieves cut charging cables to sell the valuable metal, leaving stations unusable and frustrating EV drivers. As a solution, some suggest making charging cords retractable or requiring drivers to bring their own. But would these approaches work?
Retractable Cords: A Possible Fix?
One proposed solution is a retractable cord system. Here’s how it would work:
- Drivers unlock the charging cable via an app or payment method.
- The cord extends from a secure compartment.
- Once charging is complete, the driver presses a button, and the cord retracts into a locked housing.
The idea is that making cables harder to access would deter theft. Additionally, if a thief were to use a prepaid phone and stolen card, charging stations could impose a hefty fee, reducing the profit margin on stolen copper.
Challenges of Retractable Cables
While retractable cords seem promising, there are drawbacks. DC fast charging cables contain coolant lines and are heavy, making them difficult to retract smoothly. Additionally, retractable mechanisms could be expensive to install and maintain. Some fear that thieves might still find a way to break into the housing or cut the cord while it’s extended.
The “Bring Your Own Cable” Approach
In parts of Europe, EV owners bring their own cables for Level 2 (AC) charging. This reduces theft risk because there’s no cable to steal. However, this system isn’t practical for fast charging, where specialized, liquid-cooled cables are required. It also adds inconvenience and cost for drivers.
A Multi-Layered Solution
No single fix will completely stop cable theft, but a combination of solutions could help. More secure charger designs, better station surveillance, and harsher penalties for scrap metal buyers accepting stolen copper could make a difference. In the long run, advancing wireless EV charging technology may eliminate this issue entirely.
Until then, charging providers must balance security, convenience, and cost to keep EV infrastructure running smoothly.
