Improved nanofluid cooling of cylindrical lithium ion battery pack in charge/discharge operation using wavy/stair channels and copper sheath
Abstract: In order to improve the thermal management system for cooling an electric vehicle battery pack, the thermal performance of the battery pack in two states of charge and discharge in different working conditions by using a copper sheath around the batteries and a copper sheath, as well as a stair channel on top of the battery pack and using of nanofluid as cooling fluid, has been studie...
متن کاملA State-of-Charge and Capacity Estimation Algorithm for Lithium-ion Battery Pack Utilizing Filtered Terminal Voltage
In electric vehicle (EV) and hybrid electric vehicle (HEV) application, accurate information of state-ofcharge (SOC) and capacity of each cell are required for elaborate SOC/capacity estimation algorithm of the battery pack. However, the measurement of the states of all cells using sophisticated algorithms increases the computation time beyond practicality, because the computation time required...
متن کاملLithium-Ion Battery State of Charge Estimation Using One State Hysteresis Model with Nonlinear Estimation Strategies
Battery state of charge (SOC) estimation is an important parameter as it measures the total amount of electrical energy stored at a current time. The SOC percentage acts as a fuel gauge if it is compared with a conventional vehicle. Estimating the SOC is, therefore, essential for monitoring the amount of useful life remaining in the battery system. This paper looks at the implementation of thre...
متن کاملEstimation of State of Charge of a Lithium-Ion Battery Pack for Electric Vehicles Using an Adaptive Luenberger Observer
In order to safely and efficiently use the power as well as to extend the lifetime of the traction battery pack, accurate estimation of State of Charge (SoC) is very important and necessary. This paper presents an adaptive observer-based technique for estimating SoC of a lithium-ion battery pack used in an electric vehicle (EV). The RC equivalent circuit model in ADVISOR is applied to simulate ...
متن کاملOnline Estimation of Lithium-Ion Battery State-of-Charge and Capacity with a Multiscale Filtering Technique
Real-time prediction of state-of-charge (SOC), state-ofhealth (SOH) and state-of-life (SOL) plays an essential role in many battery energy storage applications, such as electric vehicle (EV), hybrid electric vehicle (HEV) and smart power grid. However, among these three quantities, only the SOC has been thoroughly studies while there is still lack of rigorous research efforts on the other two q...
