Smarter HF charger
June 1st 2009 High efficiency and wireless
communication are the key
benefits of Powertech IQ,
the new range of high
frequency (HF) smart
chargers available from
EnerSys.
Powertech IQ HF chargers
have a real-time clock which
allows charging operations
to be programmed exactly
to take account of off-peak
electricity tariffs.
Equalisation charge can be
started when convenient
and real dates programmed
for each event.
Wireless communication
between the charger and
battery is enabled by a WI-IQ
wireless battery monitor
fitted to the main DC cable
of the battery. Information
on charge, temperature and
voltage can be uploaded
wirelessly to a PC for data
analysis.
A USB port is positioned
on the front panel of the
Powertech IQ charger for
data upload and download.
An Ethernet Port to provide
remote diagnostics is
available as an option to
enable remote management
of a charger fleet, and when
connected to a network
provide access to charging
management on a global
scale. Charge level is
indicated by colour
changing display panels and
the charger menu can be
fully programmed by the
user.
Automatic charge
optimisation is made by the
charger according to the
battery's temperature,
capacity and technology.
This occurs throughout the
charge period to
compensate for any current
loss in the DC cables. The
Powertech IQ charger will
even interrupt the charge if
excessive temperatures
occur and charge will not
commence if a defined
percentage discharge is not
reached.
Arc-less connection and
disconnection also improves
safety. More articles from Enersys Ltd: |
