An accurate assessment of the temperature distribution on the surface of the battery can be instrumental in prediction of the health and remaining lifetime in the battery/battery storage unit. Close monitoring of operational conditions and health can lead to significant saving in the overall cost and reliability of the targeted application. In this paper a new method for estimation of an effective...
With the development and popularity of Lithium battery powered PEVs (Pure Electric Vehicles), BMS (Battery Management System) with equalization techniques become a key issue in high performance PEV design. This paper introduces a linear regression based real-time State of Charge calculation method through a second-order RC model of Lithium batteries. Then a fuzzy control method is adopted to balance...
The goal of this paper is to describe the key methods for state of charge estimation. The presented techniques are current counting method, open circuit voltage and battery internal resistance method. This paper describes these methods and compares their accuracy.
Batteries have an important role in the development of electrical energy utilization, such as in renewable energy and electric vehicles. Batteries with good performance would support the devices which utilized them. Because the amount of energy stored in a battery is limited, so battery getting charging and discharging cycles. Improper charge and discharge process could decrease the battery's performance...
Lithium-ion battery plays important roles in electric drive vehicles. It has several advantages among other battery technologies such as high energy density and specific energy. The primary concerns of Lithium-ion batteries are to maintain optimum battery performance and extend the battery's life. An accurate state of charge (SOC) estimation can improve the performance of Lithium-ion battery. In this...
