Analysis of the Charging and Discharging Process of LiFePO4 Battery Pack

A serious issue relative to the construction of electronic devices is proper power source selection. This problem particular importance when we are dealing with portable operating in varying environmental conditions, such as military equipment. correct selection source. In these types devices, lithium-ion batteries commonly used nowadays, and their variety—lithium iron phosphate battery—LiFePO4. Apart from many advantages this type battery offers, high energy density, a number charge discharge cycles, low self-discharge. They also have major drawback—a risk damage due excessive or overcharge. article studies process charging discharging pack composed cells different initial levels. An attempt was made determine differences level cells. It verified, whether successive cycles reduce increase amount stored individual pack.
