Two BYD Charging Cables, One Iron Chain, and a Mystery
Around October 22, images began circulating online showing a pair of charging guns at a BYD megawatt fast-charging station bound together with an iron chain. According to the pictures described in Chinese auto media, the cables were wrapped so they could not be pulled free and used, yet the cabinet’s indicator lights glowed green, the screen displayed normally, and there was no fencing or closure notice around the site. The equipment looked healthy. The guns were simply unavailable.
That combination is what turned a small piece of vandalism into a talking point. A locked cable is not a broken charger. Whoever tied the chain had access to the site, knew how the guns are mounted, and wanted them out of service without triggering the kind of fault that would flag on a monitoring dashboard. Readers were left to guess whether a rival operator, a frustrated driver, a property owner in a dispute over the site, or someone else entirely was responsible. BYD has not offered a public explanation in the accounts reviewed.
BYD, China’s largest electric-vehicle maker, has been rolling out megawatt-level charging as a selling point for its newest models. The pitch is simple: pull in, plug in, and add a large amount of range in the time it takes to buy a coffee. That promise depends less on the hardware than on the mundane business of keeping a site clean, powered, unlocked and unoccupied. The bigger the network gets, the more of these small operational failures accumulate.
The broader context is a Chinese public charging market that has expanded at extraordinary speed. Highway corridors, shopping-centre car parks and roadside plots now host hundreds of thousands of units, run by automakers, dedicated charging companies, grid subsidiaries and franchisees. Utilization rates vary wildly. A site in a good location earns money; one on the wrong stretch of road can sit idle for most of the day. Disputes over parking spaces, electricity bills and site access are common, and enforcement is fragmented across property managers and local operators.
Charging-point operators elsewhere face the same problem in different forms, from cables cut for copper to connectors deliberately damaged by drivers angry about queues. What makes this case distinctive is the visibility. A single photograph of a chained gun travelled further than any utilization report, because it gave drivers a concrete image of a promise not kept. For a company that sells cars partly on the speed of its charging, that is a reputational cost that no engineering specification can offset.
There is also a quieter safety angle. Fast-charging equipment carries high voltage and liquid-cooled cables, and unauthorized tampering is exactly the kind of thing manufacturers warn about. Tying two guns together with a chain may look improvised, but it puts stress on connectors, cable sleeves and the locking mechanisms designed to keep a session safe. Operators generally prefer that a unit be switched off properly rather than physically restrained.
What happens next will be decided in unglamorous places: service logs, site inspections, and whether BYD or its partners say anything at all about how the guns were freed and by whom. Drivers will judge the network by whether the next station they reach is working. For now, the picture of a green light and a chain is the most efficient summary anyone has produced of how fast build-outs can outrun the management that keeps them honest.
