ABOUT

Agnikul Cosmos is a company incubated at IIT Madras and we build rockets that can take satellites up to 500 kg to Lower Earth Orbit (LEO). In May 2024, we successfully completed our maiden launch from our own launchpad (India's first private launchpad). The launch has proven all the current technologies developed by Agnikul and also earned recognition from Honourable Prime Minister of India.

RESPONSIBILITIES

• Design and develop high-voltage, high-power and high-energy battery packs from concept to prototype and qualification.

• Define battery architecture based on required voltage, current, power, energy, discharge duration, mass, and mission profile.

• Perform cell selection and characterization based on energy density, power capability, C-rate, internal resistance, temperature behaviour, cycle life, and safety.

• Design series/parallel cell configurations to meet required voltage, capacity, peak current, continuous current, and energy requirements.

• Develop battery electrical architecture including:
- Cell/module interconnections
- Busbars




- Fuses and protection devices
- Contactors
- Pre-charge circuit
- HV connectors
- Current and voltage sensing
- HV interlock and isolation monitoring

• Work closely with the BMS team for cell monitoring, balancing, SOC/SOH estimation, protection and fault handling.

• Develop battery thermal management strategies for high-current charge/discharge operation.

• Perform electrical, thermal, and mechanical calculations for battery modules and packs.

• Design and review busbars, terminals, interconnects and high-current paths, including voltage-drop and temperature-rise calculations.

• Analyse battery behaviour under peak-power and high-C-rate discharge conditions.

• Develop battery protection strategies for over-voltage, under-voltage, over-current, short circuit, over-temperature and insulation faults.

• Support battery pack mechanical design, enclosure integration, sealing, vibration isolation and thermal interfa
