Modelling and simulation of datalogging embedded module with solar panel supply and NiMH battery energy storage

The paper focuses on modelling and simulation of energy consumption of an of an autonomous embedded system with a solar cell as energy source and NiMH battery as energy storage during night. Key aspects in the design and implementation of the proposed system are presented. Simple models for energy consumption/generation for solar cell, NiMH battery charging and discharging, microcontroller and its peripherals are elaborated, tested and coupled together for complete system simulations that allow system configuration and optimization.
