Ultralife Powers Volvo (Autoliv) Automatic SOS System

In 2000, Autoliv and Volvo introduced one of the world's first post-crash safety systems, "Volvo On Call". It is a crash-robust system that automatically calls the EMS (Emergency Medical Service) Center after a crash and gives the rescue team the exact location of the accident.

The vehicle's electronic system registers the airbag deployment and sends a text message to a Volvo On Call Alarm Center through the vehicle's integrated car phone. In tandem, a line is opened so that an operator at the alarm center can talk to the car occupants and find out more about the accident. If, however, no one in the car is able to answer, the operator can send an ambulance directly to the vehicle. The location is provided by the car's GPS satellite navigation system and relayed as a part of the alarm text message.

The driver can also press an SOS-button for alerting the alarm center in case of an emergency and there is also a button for road assistance if the vehicle has mechanical difficulties or if the driver just wants to know the best way around traffic congestion. Additionally, the system can be used for tracing the car if it has been stolen.

Ultralife provides the back-up batteries for the system. In the event the automobile’s main battery or electrical system is damaged and can no longer power the SOS system, back-up batteries are required to maintain functionality. In order to provide the necessary level of passenger safety, Ultralife’s emergency back-up batteries have become an integral component of this Telematics system.

Why Use Ultralife Batteries?

Emergency back-up batteries for automotive Telematics systems must be capable of providing instantaneous high power, have an operating temperature range of -40°C to 72°C, be safe for use within the passenger compartment of a vehicle, and have a shelf life of up to 10 years. These parameters narrow the choice of battery chemistry to a non-rechargeable lithium solution.

Lithium-manganese dioxide, with its solid cathode, is clearly the logical choice manufacturers turn to for "consumer" Telematics.

Ultralife's selection of lithium-based primary (non-rechargeable) batteries provide exceptionally long operational life with high energy densities, long shelf lives and are safer than most other battery chemistries. They are ideal for a wide variety of Telematics applications including:

• Automatic Crash Notification
• Emergency Notification and Communications
