This paper focuses on state of charge (SOC) estimation for the battery packs of electric vehicles (EVs). By modeling a battery based on the equivalent circuit model (ECM), the adaptive extended Kalman filter (AEKF) method can be applied to estimate the battery cell SOC. By adaptively setting different weighed coefficients, a battery pack SOC estimation algorithm is established based on the sing...

Virtualization is an inexpensive and convenient method for setting up software test environments. Thus it is being widely used as a test tool for software products requiring high reliability such as mission critical cyber-physical systems. However, existing virtualization platforms do not fully virtualize the battery subsystem. Therefore, it is difficult to test battery-related features of gues...

Since the lifetime of a battery directly impacts the extent and duration of sensor networks, one of the key considerations in the design of sensor networks is the ability to maximize battery lifetime. In this paper, we present (1) a task modeling methodology and (2) a battery-aware real-time task scheduling technique for sensor networks. The task modeling is achieved based on task classificatio...

Modeling of the battery for 42V PowerNet system is presented. For the Battery Management System (BMS) algorithm in a Mild hybrid vehicle, accuracy in the battery model is crucial. The battery model is needed for the BMS algorithm as well as for the system computer simulation for the energy management. The battery model was composed of impedance elements and each element of the model is estimate...

Smartphone charging imposes a big burden to users because they often have to recharge their smartphones every day or even multiple times per day. In this paper we try to answer the following question: can smartphones get automatically charged without requiring explicit effort from users? To this end, we propose a new approach, called AutoCharge, to explore the feasibility of automatic smartphon...

Electric and hybrid vehicles play an increasing role in the road transport networks. Despite their advantages, they have a relatively limited cruising range in comparison to traditional diesel/petrol vehicles, and require significant battery charging time. We propose to model the facility location problem of the placement of charging stations in road networks as a multiple domination problem on...

Monolithic on-chip integration was successfully demonstrated in Si CMOS technology. The enhanced development in electronics and optoelectronics technologies has increased the need for an integrative power unit that will also decrease conduction leaks, power losses, and cross talking [1]. We present a rechargeable, all-solid-state thin-film battery compatible with microelectronics technology in ...

Developing efficient catalyst for oxygen evolution reaction (OER) is essential for rechargeable Li-O2 battery. In our present work, porous LaNiO3 nanocubes were employed as electrocatalyst in Li-O2 battery cell. The as-prepared battery showed excellent charging performance with significantly reduced overpotential (3.40 V). The synergistic effect of porous structure, large specific surface area ...

As a clean energy technology, the development of electric vehicles (EVs) is challenged by lightweight design, battery safety, and range.

Electric-drive vehicles (EDVs) have drawn more and more attention worldwide. As one of the most important parts of EDVs, battery management systems (BMSs) manage the huge amount of battery cells in EDVs and assures their safety. To achieve these goals, re‐ searches in BMS, such as battery modeling, battery state estimation, and battery balanc‐ ing have gained a new vigor. This chapter will revi...
