Assets tracking has become a major area of interest
and development in business over recent years. With
businesses becoming increasingly mobile and with the
development of GSM, GPS and GPRS technology, mobile
assets tracking has come to the forefront of this
field.
An assets tracking system usually consists of some
form of base station which has some form of wireless
communications link and a processing module to collect
and decode the information it receives. This data can
come from a variety of mobile devices, but commonly
information is transmitted from a hand held barcode
reader device which scans items, then sends the appropriate
information to the central communications unit.
Widely used in the haulage and courier industries for
tracking the contents of Lorries and vans to give details
about deliveries including the product delivered times
and places of delivery.
In order to ensure these systems are affective, the
mobile readers used must be reliable; in order to ensure
this, the battery used to power these devices also needs
to be reliable. Previously NiCd or NiMH batteries have
been used for such applications, but due to the increasing
complexity of these devices, the power requirements
have also increased. NiCd and NiMH can become subject
to such high demand and use and their performance can
diminish quickly.
The advent of Lithium technology, specifically rechargeable
Lithium Ion technology has increased the capacity and
reliability of rechargeable cells. This is the technology
now being utilised by manufacturers of mobile assets
tracking systems, taking advantage of the long shelf
life, high capacity, high voltage and wide operational
temperature characteristics of Lithium batteries.
