Battery management system for CubeSat
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryThe purpose of this project is to make the working model of battery management system for 3U-CubeSat. This includes thermal control for maintaining temperatures, charging and discharging control, cell balancing to increase battery life and health telemetry of battery. Battery management system is very important for satellite because conditions change so drastically in space. Therefore, for proper working of satellite, we have to make battery management system in order to maintain the performance of battery under rapid changing atmospheric conditions.
Project ObjectivesThe main objectives of this project are:
- To develop battery management system according to the standards of 3U-CubeSat.
- To design a DC-DC converter for charging and discharging control units of battery.
- To implement an effective active cell balancing technique for cell balancing of battery.
- To manage and control the temperature (thermal control) of a battery.
- To monitor health telemetry of battery through sensors and to send the data of sensors to the microcontroller, on the basis of this data microcontroller will execute instructions for managing battery.
After literature review, we will move toward components selection and schematic of design. After schematic design we will simulate each sub system on simulation software. Then we will design final software for battery management system and procure components. After finalizing software design and procuring components, we will move toward final hardware design, in which complete hardware will be designed.
Benefits of the Project- Battery Management System produced in this project can be used in nanosatellites for battery maintenance.
- Research and literature review done for this project can be helpful in other space missions or satellites as battery management system is essential for the health of battery and also to increase the battery life.
- Institute of Space Technology, Islamabad is also a potential beneficiary of this project as the mentioned project can help the institute in research, design and analysis of nanosatellites which can prove to be a step further for IST in its quest for space exploration.
- Government and private organizations working in the field of space sciences can also use this project as a helpful tool for their space expeditions.
In this project we design a buck boost converter which control charging and discharging of battery. Temperature sensors are used to measure temperature of battery. The output of temperature sensor is also connected to ADC module of microcontroller. Switched Capacitor, active cell balancing technique is used for cell balancing in with quad switches and capacitors are used. AVR microcontroller AT32UC3C is used for interfacing different modules.
