Telematics
is a technology area based around vehicle-based electronic
systems designed for the collection and dissemination of data.
Telematics is widely used in a number of transport industries
including haulage and taxi companies. Vehicles are equipped
with terminals which can access services such as on-line navigation
and information services, emergency assistance and traffic
assistance. It can also be used for vehicle tracking, deployment
information as well as internet access, basically giving access
to any form of knowledge from any remote location.
Many of
these devices are used to provide safety critical information
and for this reason, the remote devices used must have a reliable
dedicated power source independent of e.g. the vehicle battery.
The batteries used for these devices also need to cope with
the high drain characteristics of the advanced technology
used and should be able to operate in extreme conditions.
For this reason, most telematics devices utilise Lithium technology
including Lithium Ion for rechargeable applications and Lithium-thionyl
chloride, Lithium-sulfur dioxide and Lithium-manganese dioxide
for non-rechargeable needs.
