Main objectives of the project are as follows: i) Voltage regulation: Regulate the voltage at the output capacitor of the buck to 12 V ii) Battery management system for Li-ion batteries: over-charged, over-discharged and short-circuit protections with balancing function iii) Choose a test load for demonstration purposes that is rated for 12 V iv) Choose the number of series and parallel combination of Li-ion cells to ensure current and voltage requirements of load are met while ensuring maximum life of batteries v) Ensure correct functionality under all cases. A few examples are: - When supply exceeds load requirements and batteries are full - When supply exceeds load requirements and batteries are not full - When supply does not meet load requirements and batteries are full - When supply does not meet load requirements and batteries are at cut-off voltage As the freelancer you will have to make sure to cover all use cases and ensure functionality under all cases. vi) Provide a well documented conceptual design solution that discusses the scope of work and explains the solutions vii) MATLAB/Plecs simulations that show correct functionality viii) List of all the components for prototyping ix) Test document that explains the testing procedure for prototyping Expected timeline: 2 weeks

Hi Sir, We have designed battery management systems previously with all the functionalities you have mentioned before. we are able to design lithium ion, lipo and other cells bms very efficiently, we also able to design bms for minimum of 2 and maximum of many tens cells together. we used these bms in hybrid bikes. Lets talk to us on your project. We are professional engineers and developers who do such projects from the last eight years. We offer you our skills for this project at very low rates comparatively without compromising the quality of work. Let me introduce you to our company TURKTRONICS. We are TURKTRONICS. We are professionals with 8+ years of experience in Circuit designs, PCB designs, embedded system solutions, mobile app development, programming and software development. We provide complete end to end solutions for all kind of development projects. IOT is our strong point. In this bid, prototyping and shipping cost is not included however paying extra slight of money to include prototypes. We have the manufacturing facility and we produce the very high standard PCB boards and send ready products to customers doorsteps via DHL. We care about our clients and help them to get out of any potential problem throughout the projects and also give post completion technical support if ever required. We are very much looking forward to hear from you on this in coming days! Cheers!!! Ahmad Lead Technical Engineer TURKTRONICS An Internet of Things Company
