This thesis focuses on using the thermoelectric generator in energy harvesting, the proposed system is used to charge a battery pack of (Samsung ICR18650) with total capacity of 5.2 A.h and with nominal voltage of 22.2 V, from a pack of the commercial TEG product (TEG1-12611-6.0) manufactured by TEC company with maximum power of 282 W and maximum voltage of 16.8 V, the power is delivered through a Boost converter with an output inductor for charging current and voltage ripple minimization, the converter is controlled by a three stage controller: the Maximum Power Point Tracking (MPPT) uses Perturb and Observe (P&O) technique, the second stage is triggered when the MPP current reaches the maximum limit which is 5 A , during which the battery is charged with a constant current 5 A that is controlled by a Proportional-Integral (PI) controller, the third stage is triggered when the battery voltage reaches the maximum charging voltage of the battery which is 25.2 V, the battery is charged by a constant voltage that is controlled by a PI controller.
The thesis uses Psim for TEG, converter, and controller simulation, while the MATLAB and SISOTool are used for TEG modeling and PI controller design.
The simulation results show that the system works with a minimum efficiency of 93.6 as will be shown in the thesis.

The boundary conditions for battery chargers include the charging current and battery voltage limits which have

demands. Maximum power point tracking (MPPT) mode, power matching mode and voltage stabilization mode
will be integrated in the control algorithm of the battery charger. This paper puts a schematic design for a system
that harvests energy from a thermoelectric generator bank of a TEG1-12611-6.0 TEG modules in order to charge
a battery bank of Samsung ICR18650 Batteries using constant current (CC) and constant voltage (CV) charging profiles.
