“…This means that at large temperatures differences across the TEG, the generator can still produce close to maximum power. Further detailed description, mathematical modelling, performance testing and analysis for this TEG can also be found in (Kinsella, O'Shaughnessy, 2014, O'Shaughnessy, Deasy, 2013 The TEG is intended to be used as a power source to charge a rechargeable 3.3 Volt lithium-iron-phosphate (LiFePo4) battery, specifically the ANR26650 cylindrical cell manufactured by A123 Systems, termed the 'primary' battery henceforth. LiFePo4 batteries are known for their good safety characteristics and long life cycles.…”
