EV-Garm

Safety Monitoring System for Li-Ion Batteries in Electric Vehicles

EV-Garm is a new carbon monoxide sensing system – designed specifically for electric vehicles undergoing repair, service or maintenance. The system offers critical safety monitoring in automobile repair facilities. Sensing early signs of Li-ion battery venting, this system is an indispensable safety solution for any service center dealing with battery electric vehicles. Featuring innovative, patent-pending technology our system sets a new standard in safety monitoring.

When Safety Matters: Lessons from the Workshop

Morgan Svennarp from ECG Lack & Bilvård in Osby shares his experience of dealing with an electric car in a thermal runaway in his workshop. It’s a stark reminder of the challenges posed by EVs and the importance of being prepared.

How do you protect your personnel and premises?

EV-Garm offers early detection and critical safety measures to help you stay ahead of potential risks.

How the sensors work

If battery distress or failure is detected, the sensors will produce a loud siren signal, flashing light and email notification, which alerts the workshop staff to take necessary actions and precautions.

Through early detection of thermal runaway, EV-Garm:

Can reduce necessary EV quarantine and downtime
Makes the work environment safe for workshop staff

How to place the sensors

When a damaged vehicle is in a workshop or quarantined. EV-Garm continuously monitors it for early signs of ventilation, thermal runaway, and fire risk.

The sensors should be placed close to the battery's over-pressure valve (the maximum distance should be 30 cm). This enables the sensor to react to early signs of Li-ion battery venting.

User groups

With the increasing use of EVs, the risk of thermal runaway has escalated. At Dafo Vehicle Fire Protection AB, we are working to make electrification safe by focusing on preventing/delaying thermal runaways.

We have identified groups that need quick and early warning of potential thermal runaway to make it possible for them to take appropriate actions quickly. These are Auto Mechanics and people working with Automotive Quarantine.

Auto Mechanics

Auto Mechanics at a workshop can fit sensor modules to the EV before work is started. They can follow procedures and evacuate the workshop if the sensors start alarming.

Quarantine facilities

Quarantine facilities store damaged EVs while they are investigated by a forensics team or repaired. The solution will reduce the quarantine time and speed up the entire process.

EV-Garm works perfectly with larger vehicles as well, for example electric buses och mining machines undergoing service or repair in a workshop. Since it is a mobile system, you can easily move it between your vehicles.
