  4. 3. Optimization of battery pack assembly of second life cells to reduce costs

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Akash Prasad Chowdry; [2022]
    Keywords : Batteries; second life cells; active cell balancing; lossless cell balancing; off-grid solar; solar home systems; Batterier; second life cells; aktiv cellbalansering; förlustfri cellbalansering; solceller utanför nätet; solcellssystem för hemmabruk.;

    Abstract : Batteries account for 50% of the overall cost of solar home systems (SHS). The battery packs degrade over time and when they reach 70% state of health (SOH), the whole SHS is discarded. In the predominantly rural off-grid context, battery replacements are expensive and impractical. The customers are often dozens of km away from any sales point. READ MORE
