Charge transfer and energy transfer analysis of battery charge equalization

2015 IEEE International Conference on Automation Science and Engineering (CASE), 2015
Cell charge imbalance is a very common issue in the battery system, which can cause efficiency and even safety problems. To solve this issue, many types of battery charge equalizers have been designed. In this extended abstract, we will focus on the analysis of charge transfer and energy transfer in the battery charge equalization process.

Charge-transfer polarons and excitons

Physical Review B, 1991
We show that polarons and excitons of charge-transfer origin arise quite naturally in the {ital p}-{ital d} model of high-temperature superconductors. We consider the limit in which on-site Coulomb repulsion on both Cu and O is taken to be infinite and treat the Cu-O repulsion {ital U}{sub {ital p}{ital d}} in the Hartree-Fock approximation.

Charge Transfer in Polar Crystals

Radioelectronics and Communications Systems, 2022
In some noncentrosymmetric crystals, their internal polarity can significantly influence the electric charge transfer. Sometimes, mixed ion-covalent bonds that are intrinsic to polar crystals are extremely delicately balanced, therefore, external stimuli (temperature or electric field) lead to a large change of the specific electrical resistance.

Symmetric charge transfer to multiply charged ions

Physical Review A, 1989
The asymptotic theory of symmetric charge transfer is adapted to apply to ion-ion collisions through allowance for curved nuclear trajectories. The theory compares well with {ital ab} {ital initio} quantum calculations on He{sup 2+}-He{sup +} collisions and is applied to five members from each of the Li-like and Na-like sequences.

Lack of Charge Transfer in Aromatic Charge—Transfer Complexes

The Journal of Chemical Physics, 1964
Halogen pure electrical quadrupole resonance frequencies have been measured in the three 1:1 complexes, CBr4·p-xylene, CCl4·p-xylene, and Br2·benzene. From an examination of the measured frequencies of the complexes and the halogen-containing compounds (CBr, CCl4, and Br2) together with information from the x-ray structure determinations for two of the

Charge-Transfer Excitons in DNA

The Journal of Physical Chemistry B, 2008
There have been a number of theoretical treatments of excitons in DNA, most neglecting both the intrachain and interchain wavefunction overlaps of the electron and hole, treating them as Frenkel excitons. Recently, the importance of the intrachain and interchain coupling has been highlighted. Experiments have shown that in (dA)n oligomers and in duplex

Charge transfer in the eikonal approximation

Physical Review A, 1986
A new technique has been proposed and outlined to calculate the rearrangement amplitude in the eikonal approximation, taking a consistent account of the internuclear potential term in order to satisfy the boundary condition properly. The six-dimensional integral of the Glauber eikonal transition amplitude has been reduced to a single-dimensional one ...

Supramolecular charge transfer nanostructures

Phys. Chem. Chem. Phys., 2014
Supramolecular organization of π-conjugated chromophores into well defined nanostructures has gained much attention due to their promising role as active components in organic electronics. Charge-transfer (CT) nanostructures, in which aromatic donor (D) and acceptor (A) molecules are alternately arranged, (mixed stack) have emerged recently as ...

A Fundamental Comparison of Incomplete Charge Transfer in Charge Transfer Devices

Bell System Technical Journal, 1973
Using a small-signal analysis, we present a general comparison of the more important contributions to the incomplete transfer of charge in the following charge transfer devices: (i) the polyphase charge-coupled device and the IGFET bucket-brigade shift register, where individual charge transfers are single-step processes, and (ii) the two-phase charge ...
