Foldable
module of carry pack SPV battery charger for
Defence
|
CEL
has developed a Lightweight Foldable Solar Charger
For Manpack Radio Equipment (PM 640-MP) for use by
the Army and Para-military Forces for charging re-chargeable
lead-acid and nickel-cadmium batteries used in low
power manpack radio sets. The Solar Charger totally
eliminates the second set of batteries and/or heavy
manually operated generating set (with fuel) that
normally form part of a manpack radio detachment thereby
reducing at least one man load. It is hence most suitable
for the soldiers operating at high altitudes, remote
inaccessible areas and for long range patrols.
The
Solar Charger consists of a pair of foldable solar
photovoltaic (SPV) panels. Each panel is of 24W capacity
and capable of charging a 12V battery. The two panels
can be connected in series or parallel for charging
24V/18V or 12V battery systems as required. The charger
is provided with a support stand for the SPV panel,
an Indication Unit having a current meter and requisite
connectors; all capable of being assembled and packed
in a water-proof carrying harness.
Indication
Unit helps the user to correctly orient the SPV panel
for capture of maximum sun isolation and also know
the charging current.
