An expandable power bank with PV Charging capability

This paper presents a sustainable power storage device for household and everyday needs with the use of lithium-ion batteries. The lack of a portable power source with has always been a problem for various needs be it household or aerospace or defence purposes. The existing technology often compromises in the safety of the device and is suitable only for lower power requirement electronics such as smartphones. This expandable power bank aims to be a higher capacity device to be able to power higher-end electronics such as laptops, television. The implementation of various safety features such as over current, over voltage protection makes it more robust and increases the longevity of the device the power bank can be charged either through either a PV source or a wall point. This paper investigates various types of available technologies for its architecture using software systems. The simulation results of the system and the hardware components which are needed to be used are given clearly with the ratings.
