Design of an Uninterrupted Power Supply with Li-Ion Battery Pack: A Proposal for a Cost-Efficient Design with High Protection Features

While decreasing their cost, lithium-ion batteries began to enter a vast domain for energy storage field, including solar systems and electric vehicles, due high density compared other types. Besides, li-ion require safe secure ground reach the best performance decrease explosion risk. The operation of battery is based on main protection features balancing cells. This study offers BMS design that protects from overcharging, over-discharging overheating. It also offering passive cell balancing, an uninterrupted power source load, monitoring data. used controller Arduino mega 2560, which manages all hardware software features. Software include 1) variable charging speed according status, 2) measuring state health charge, 3) controlling driver, 4) regulating charge discharge voltage, 5) measure display readings.
