| 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.
