Power supply provides the necessary electrical and pneumatic power onboard
the missile. DRDO has developed silver-oxide-zinc primary, nickel-metal
hydride secondary, and lithium thermal batteries for onboard power supplies
to various missiles.
28 V Dual Power Pack
A 28 V dual power pack battery has been developed to meet the guidance and
pyro requirements. This is a two-in-one battery containing two sections with
same electrolyte source for both the sections.
28 V dual power pack
Section I gives power to guidance and caters to a load of 15 A continuously,
and section II gives power to pyros and caters to a pulse load of 50 A. It
has a novel electrolyte container in the form of coil wound over the
electrode stacks. The battery has bipolar configuration, which helps in
avoiding inter cell links. It is activated by a gas generator.
70 V Primary Reserve Battery
70 V primary reserve battery
A odd shaped 70 V primary
reserve battery has been developed to meet the control system requirements.
It has been ruggedised to meet the severe climatic and dynamic environment,
which a missile faces during the operation.
The battery is hermetically sealed and is activated by a gas generator. It
is capable of meeting very high peak power requirements.
