Wave functions for continuum states of charged fragments
Physical Review A, 1994Briggs's representation [Phys. Rev. A 41, 539 (1990)] of the Moller wave operator for multiparticle wave functions is applied to charged fragments using a limiting procedure to correctly account for the slow decrease of Coulomb interactions with distance.

Hybrid Model to Calculate the State of Charge of a Battery
2021Batteries are one of the most important component in an energy storage system; they are used mainly in electric mobility, consumer electronic and some other devices. Nowadays the common battery type is the liquid electrolyte solution, but it is expected that in some year, the solid state batteries increase the energy density.

Battery State-of-Charge indication
2002One of the tasks of a Battery Management System is to keep track of a battery’s State-of-Charge (SoC), as discussed in chapter 1 of this book. Information on the SoC can be used to control charging and discharging and it can be signalled to the user.

State of charge estimation for electrical vehicle batteries
2008 IEEE International Conference on Control Applications, 2008Lithium ion batteries play an increasingly important role as high-rate transient power sources for hybrid electric vehicles, cycling around a relatively fixed state of charge (SOC). A crucial step in enhancing the performance of these batteries is the estimation of the state of charge as a function of the load.

Forecasting battery state of charge for robot missions
Proceedings of the Symposium on Applied Computing, 2017Due to limited power onboard, a significant factor for success of distributed teams of robots is energy-awareness. The ability to predict when power will be depleted beyond a certain point is necessary for recharging or returning to a base station. This paper presents a framework for forecasting state of charge (SOC) of a robot's battery for a given ...

A battery state-of-charge indicator for electric wheelchairs
IEEE Transactions on Industrial Electronics, 1992Deep-discharge-type lead-acid batteries used in most electric wheelchairs require acurrate battery state-of-charge indication to prevent stranding and to provide economical operation of the wheelchair. A monitoring technique combining the open-circuit voltage and the coulometric measurements had been previously implemented on a microcomputer-based ...

State of charge monitoring for road vehicle batteries
IEEE 2002 28th Annual Conference of the Industrial Electronics Society. IECON 02, 2003The paper deals with batteries for road vehicles. In particular, battery behaviour is analysed focusing on the efficiency in different operations such as charge and discharge. The parameters of a simplified model of the battery are considered to monitor the state of charge and the efficiency of batteries for road vehicles.

State of charge estimation and battery balancing control
2015 54th IEEE Conference on Decision and Control (CDC), 2015In this paper, we propose an algorithm to solve the balancing problem of multi-cell battery systems consisting in the equalization of all cells state of charge (SoC). A nonlinear cell model is presented and experimental LiFePO4 battery cell parameters are used.

State-of-charge indicators [batteries]
Proceedings of MILCOM '94, 1994Summary form only given. Prediction of the capacity remaining in used batteries is important information to the user. Each year millions of dollars are spent on batteries for use in portable electronics equipment. In order to maintain readiness, users currently replace batteries on a conservative schedule. This practice results in the waste of millions

Reference states for charging cycles
Electrochimica Acta, 1971Abstract Confusion exists about the precise reference states involved in charging cycles. A clarification is presented here, involving comparison of the methods of Lowry and Bousfield, Born, Jost and kirkwood, the last yielding the exact transfer work for an arbitrary charge-distribution model. Application to the ionic case, with an internal relative
