“…1) differs fundamentally from the equivalent circuits of batteries used in the statistical and constructive models. [12][13][14][15] In the equivalent circuits, many elements do not correspond to some objects or processes taking place in a battery. Intention of the equivalent circuits consists in a reflection of the found empiric correlations.…”

At the present time due to the widespread of electric and hybrid vehicles there is a need for batteries practical models construction. In this study, a fundamentally new non-linear structural method was used for battery work modeling. A non-linear structural model is developed of relaxation processes after battery charging. The model is correct for alkaline, acidic and lithium-ion batteries. The comparison of the model solutions with the experimental data for the alkaline batteries showed that the relative error does not exceed 3%. Despite of an existence of a lot of different models of batteries, at the present time, only a few methods exist for these models development, namely: the statistical approach, the electrochemical method and the structural method.The statistical approach for the batteries model development is used on a first stage of batteries investigation, when there is very poor information about the battery being studied. 1-3The electrochemical method method is the most fundamental one. As a rule, practicians using the batteries electrochemical models in real electrochemical systems point out two disadvantages of those models;4 Firstly, the electrochemical models contain very many parameters describing a lot of local processes and phenomena. Secondly, those models are very cumbersome and complicated for a practical use. 5,6 In our earlier manuscript, 7 the fundamentally new non-linear structural method was proposed for battery work modeling. This method conserves all the benefits of the traditional structural method. But it can be used for work modeling of batteries in conditions of high currents that usually are encountered in frame of different modes of their operation.In the work, 8 the battery non-linear structural model was successfully used for modeling of self-discharge processes.In this work, on a basis of the battery non-linear structural model, a voltage relaxation is studied after charging of cadmium-nickel batteries. This work is a continuation of the works 7-11 devoted to analytical and structural modeling of different batteries work modes. Theoretical AnalysisFor analyzing a voltage change on battery terminals after charging, let us use the battery non-linear structural model 7 without taking into consideration a current distribution on depth of the porous electrode (Fig. 1).On the Fig. 1, C 2 is the main pseudo-capacitor modeling work of the main current-producing reaction in nickel-cadmium batteries;C 1 is a parallel pseudo-capacitor modeling creation of unstable phases on oxide-nickel and cadmium electrodes. As it was shown in the work, 7 it is just creation of those unstable phases, what can explain an initial relaxation field of a discharging curve of any alkaline batteries. For the oxide-nickel electrodes, they are highly-oxidized unstable nickel hydroxides. At the same place, there was shown that[2] * Electrochemical Society Active Member. z E-mail: galushkinne@mail.ru This is why practically the pseudo-capacitor C 1 does not influence the total capacity of the battery.

“…Its disadvantages are the bulky construction, low efficiency and the presence of mechanical commutators and brushes. Its use is limited to light, high speed and maintenance-free vehicle applications [60][61][62][63]. Thanks to the simplicity of speed control, DC motors are widely used in low power HEVs, such as city cars.…”

Pollution derived from transportation systems is a worldwide, timelier issue than ever. The abatement actions of harmful substances in the air are on the agenda and they are necessary today to safeguard our welfare and that of the planet. Environmental pollution in large cities is approximately 20% due to the transportation system. In addition, private traffic contributes greatly to city pollution. Further, “vehicle operating life” is most often exceeded and vehicle emissions do not comply with European antipollution standards. It becomes mandatory to find a solution that respects the environment and, realize an appropriate transportation service to the customers. New technologies related to hybrid–electric engines are making great strides in reducing emissions, and the funds allocated by public authorities should be addressed. In addition, the use (implementation) of new technologies is also convenient from an economic point of view. In fact, by implementing the use of hybrid vehicles, fuel consumption can be reduced. The different hybrid configurations presented refer to such a series architecture, developed by the researchers and Research and Development groups. Regarding energy flows, different strategy logic or vehicle management units have been illustrated. Various configurations and vehicles were studied by simulating different driving cycles, both European approval and homologation and customer ones (typically municipal and university). The simulations have provided guidance on the optimal proposed configuration and information on the component to be used.

Hybrid electric vehicles (HEVs) are very promising sustainable mobility solutions. Series, parallel and series-parallel (SP) seem to be three most promising architectures among the multitude of hybrid architectures, and it is possible to find them in a multi-applications such as the motorcycles, family-cars, hybrid city busses and sport cars. It is import to have a well configured model in order to develop the different control strategies (CsTs) for each application. Therefore, a multi-architecture/multi-application (MAMA) approach capable of identifying the most energy efficient hybrid architecture considering both the dimensions of key components: electric motor (EM), battery, internal combustion engine (ICE) and the optimal control is presented. Basis of the model is the energetic macroscopic representation (EMR), which has been combined with object oriented programming (OOP) in order to enhance its modularity and reuse capabilities. The obtained results show, that different hybrid architectures are most adapted for different applications. Moreover, the robustness of the results using real time control algorithms are studied, showing that CsT matters. The obtained results contribute to simplify and harmonize the design of hybrid solutions for multiple applications.
