EV Charger Tamper Monitoring

The sensors we mount on the charger

Hardware fitted to the unit, supplied as part of the charging station management solution. Three things, chosen because they are the three that precede almost every repeat repair.

1. 1

   Tilt

   Orientation against a baseline taken at commissioning. A pedestal being worked loose, leaned on hard or pulled at shows as a change in angle well before it shows as a broken mounting.

2. 2

   Impact

   Force applied to the unit, with the magnitude recorded rather than a bare alarm. A vehicle reversing into a bollard and a person attacking a display are both impacts, and the difference is in the trace.

3. 3

   Panel opening

   The enclosure being opened, which is unambiguous. There is no innocent reading of a service panel open at eleven at night with no job raised against that unit.

The sensors are mounted with the unit rather than built into it, which is what allows them to be fitted to chargers already in the field, including chargers that are not ours.

How it reaches your CMS

1. 1

   The hardware reports to the platform

   The sensors communicate into the charging management system over the site link the chargers already use. No separate alarm panel, no second system to check.

2. 2

   The event lands with its context

   Time, unit, site, what fired and at what magnitude, whether a session was running, and whether a job was open against that unit. A panel opening with a technician dispatched is maintenance; the same event with nothing raised is not.

3. 3

   A ticket opens on its own

   Through the same automated ticketing that handles charger faults, routed by what was detected, before anyone is told.

4. 4

   The response is per site

   Alert, trigger a camera at that moment rather than searching footage later, stop charging where continuing could be unsafe. Returning to service takes a person.

What an operator gets from it

1. 1

   The repeat repair gets a cause

   A unit that fails three times faster than the rest of the estate is either taking heavy legitimate use or taking something else. The event log answers that. The repair record never will.

2. 2

   Evidence that holds up

   A timestamped event with the unit, what fired and the site state around it is what an insurer or a landlord will accept. An alert saying tamper detected supports nothing.

3. 3

   Camera footage you can find

   Triggered at the moment of the event, so it is retrieved by timestamp rather than searched for across days.

4. 4

   Fewer alerts the team ignores

   Because the platform can read a sensor against live session and job data, most of what would otherwise be a false alarm resolves itself before it reaches anyone. An alert the team does not trust is worse than none, since it also creates the impression of coverage.
