EMERGENCY
PLUG
CONTROL THE SCENE AND ENSURE THE SAFETY OF EVERYONE AROUND IT
How it Works?
When the Emergency Plug is turned on it performs a self test to confirm it is in proper working condition. Once this is completed the plug flashes green to indicate it is ready be used. Once plugged in, the Emergency Plug recognizes and communicates the desired PP and CP signal to activate the EV’s safety protocol. The plug will display one of the following colours:
Solid Blue - The Plug is connected to the charging port and has contact with the EV. The EV is in its charging safety mode and cannot be moved under its own propulsion.
Flashing Green - The Plug is connected to the charging port but has no contact with the EV. The Plug is, therefore, unable to prevent any unpredictable vehicle movement.
Flashing Yellow - The Plug is connected to the charging port and has limited contact with the EV. The Plug may work, however in order to guarantee 100% functionality, the Plug requires both the PP and the CP signals.
​
Flashing Red - The Plug previously had some or full contact with the EV (is was either blue or yellow), but now lost contact completely (both the PP and CP signal).
Emergency Plug and North American Vehicles
The Emergency Plug is designed to work on all makes and models of EV vehicles. As seen below, the Emergency Plug suits a variety of Type 1 connections and includes an adapter for Tesla vehicles
Frequently Asked Questions
Does the emergency plug switch off the high voltage and main power?
​
No the Plug does not switch off the high voltage and main power, This means all the electric options, such as windows. Seats, lights of the EV can still be used.
​
Does the emergency plug activate the parking brake or shift vehicle into park?
​
Regulations oblige an EV manufacturer to ensure that the EV will not drive away under its own propulsion. Each EV manufacturer is free to find a suitable solution to prevent this from happening.
​
An interlock (HVIL) is a safety feature of EVs that protects individuals during the assembly, repair, maintenance and operation of an EV as well as in the event of an accident. This includes when the airbags have been deployed, or if the first responder loop has been cut. However, even when the HVIL should have been deployed, it cannot always be relied upon it
​
-
There is no external indication that the interlock is properly activated.
-
It is a mechanical system that is prone to failures and may even become welded together during an accident.
-
There are several situations when it might not be deployed, for example if the EV is not severely damaged or the airbags have not been deployed due to mechanical failure.
