The Electric Vehicle Emergency Plug® H3 is a patented safety device designed to help first responders, recovery personnel, and technicians safely secure electric vehicles during emergency incidents. By plugging directly into the vehicle's charging port, the Emergency Plug® H3 temporarily prevents the vehicle from moving under its own propulsion, reducing the risk of unexpected vehicle movement while rescue, recovery, or service operations are underway.
The H3 version incorporates a software enhancement that provides a warning indication related to critical battery pack temperatures while maintaining the core functionality that has made the Emergency Plug® a valuable EV response tool. Designed for use on electric passenger vehicles, commercial vehicles, trucks, and buses, the device provides a simple, universal solution for improving scene safety while allowing essential vehicle systems to remain operational.
