ONBOARD POWER SUPPLIES

     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.

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.
