Full textFast charging of batteries is a major challenge for the development of electric vehicles. A deployment of high power chargers is underway. These high power levels motivate research on batteries, with the aim of significantly reducing their charging times.For a battery cell of given characteristics, the charging power is limited by electrical, thermal and lifetime considerations. This thesis then wishes to make a contribution to the reduction of the charging time, by taking a numerical approach including modeling, simulation and optimization. It also compares 4 cell references of different materials and different energy densities.First, models of the electrical, thermal and aging behavior of a cell are developed separately, then coupled. In a systematic way, the models are presented, their calibration procedures are described, and they are compared with experimental data. Particular attention is paid to the effect of high current regimes under different thermal conditions. This made it possible to extend their respective domains of validity.Then, an accelerated aging campaign is carried out on 3 cell references. It compares the effect of the charging current, the end-of-charge voltage and different thermal conditions on the degradation, within the framework of a reference charging protocol. The results made it possible to identify several strategies for reducing the charging time, regarding the choice of a cell reference, thermal management, and the optimization of the charging protocol.This last strategy is finally studied. A method of definition of a charge protocol, containing several stages of constant current, is developed based on numerical optimization. The method makes uses the electro-thermal model implemented. It is then used to define 5 optimized charging protocols which are subjected to accelerated aging tests. The degradation is compared to that observed for the reference charging protocol. Under comparable conditions with the reference protocol, the optimized protocols make it possible to reduce the charging time and/or the degradation

This thesis describes the application of Porous Electrode Theory and supervised machine learning to lifetime prediction for 18650 lithium iron phosphate (LiFePO₄ LFP)/graphite cells subject to mixed galvanostatic and potentiostatic fast charging policies. Porous Electrode Theory is used to predict battery lifetime by parameteric reductions of effective solid-phase Fickian diffusivities, electrolytic Stefan-Maxwell diffusivity, and Butler-Volmer exchange currents. Parameter estimation and uncertainty quantification are formulated as least squares optimization over galvanostatic discharge curves with Bayesian estimation of uncertainties. A battery lifetime approach from the literature is extended with identifiability analysis to enhance fidelity of the inverse problem, the attribution of degradation modes, and the accuracy of parametric power-law lifetime predictions. Multiphase Porous Electrode Theory (MPET) is also explored in this thesis. In MPET, each particle of the porous electrode ensemble is described by generalized Allen-Cahn-Hilliard dynamics. Single-particle dynamics are governed by firstprinciples free energy landscapes as opposed to inductive fits to open-circuit battery voltages. Multiscale parameter estimation and central limit theorem analysis are implemented, enhancing the suitability of MPET for capacity fade predictions. Supervised machine learning algorithms utilizing feature-based correlations for battery lifetime are described. Electrochemical features that go beyond the discharge-only model provide improved lifetime predictions, generalized voltage analysis indiscrimant of (dis)charge protocol or data, and a clear connection between battery physics and machine learning, and suggest an optimal charging protocol.

Full text30 % of the French population being over the age of 60 years in 2035, the notion of accompaniment of the elderly dependence is a societal challenge with the imperative of risks prevention at home. It is in this context, with the arrival of the technologies of integration and the IoT that we undertook to conceive and realize a miniature electronic patch capable of geolocalization to trigger alarms in the case of fugue, fall or wandering. A challenge is the design of antennas on flexible substrates as key elements of the functions of geolocalization and charging by induction. A modeling work allowed the optimization of printed antennas presenting a good compromise integration / performance. A technological process in the cleanroom was developed to carry out bilayers antennas on flexible substrate (polyimide). Several prototypes of complete patch were tested and validated in the EHPAD center

Full textCharging time has become one of the main concerns limiting the development of electric vehicles. To counter this problem, it is necessary to design suitable thermal management systems to both preserve the health of batteries longer and to be able to shorten their charging time. For a battery cell with specific characteristics, the charging power is constrained by electrical and thermal considerations. This thesis focuses on evaluating and optimizing the thermal management of a battery module by utilizing cooling through the connectors. The model-based design approach is employed as a method to investigate this solution, supported by numerical simulations and experimental tests to validate the accuracy of the proposed model.First, models of the electrical and thermal behaviors of a cell are developed separately and then coupled. The models are systematically presented, their calibration procedures are described, and they are compared with experimental results. Particular attention is paid to the electrothermal modeling of the Jelly roll present at the heart of the cell by proposing a suitable mesh. Then, an experimental test campaign is carried out to calibrate the electrothermal model of a 12-cell battery module. This model is validated through a second wave of tests. A new thermal management approach is proposed, where the battery module is cooled not only by the bottom cooling plate, but also by a second cooling plate located on the busbars. Through simulations and experimental tests, this new configuration presents significant improvements. The thermal time constant is reduced allowing for a faster cooling of the module. In addition, the maximum temperature reached by the battery when charging with this dual cooling system is lowered compared to the conventional approach. One of the key advantages of this configuration is that the upper cooling plate acts as a thermal bridge, promoting temperature homogenization inside the battery module. As a result, it supports a uniform aging process of batteries, ensuring their longevity and optimal performance.Finally, a fast-charging profile has been optimized for two different protocols. The first protocol is the multi-step, and the second involves transforming the discontinuous profile of the multi-step protocol into a smoother profile using splines. The work on the charging profile aims to simulate fast charging and make a comparison in terms of charging time between the conventional architecture based on bottom cooling and a new configuration integrating an additional cooling source via the connectors

Full textLithium ion (Li ion) secondary batteries have become the most prevalent technology for a broad range of electronic devices from consumer gadgets to high-end locomotives and energy storages in smart grids. The rapid proliferation of both mobile and mobility devices, and recent developments in electric vehicles (EVs) have tremendously increased the demand for Li ion batteries (LIBs) and indirectly created a huge dependency of peoples’ mobility life. Therefore, now it is extremely critical to have LIBs to continuously power up the mobility devices for longer period of time. Anyway, as a rechargeable energy source, the LIBs will naturally drains its’ capacity after a certain period of time permitted by the power demand of the device and the storage capacity of the battery. Therefore, any charging mechanism which can charge-back the battery up to the fully charged status within the shortest possible time, also called fast charging, is highly demanded and extremely valuable in this context.However, the fast charging itself is a very challenging issue due to a number of reasons such as the complex effects (polarization, li-plating, li-deposition, depletion of active materials and etc.) of multi-disciplinary factors co-exists within the internal reactions, limitations in measuring advanced electrochemical and electro-physical factors, the inherent safety issues with the use of high rates and the tendency of deteriorating health and cycle life of a battery as a most common aftermath of fast charging. Therefore, a number of different approaches can be found in the battery research and literature, and mostly realized under three different sections: one is the introduction of new chemistries which can store more electric power, the second is the structural or design changes which can tolerate some of the adverse effects of fast charging or may be even improve their performances and the third and most interesting is the algorithmic based fast charging protocols which can also help to leverage the performance in both the other approaches.Therefore, our thesis has focused on a new fast charging protocol for LIBs to fully charge within about 20 minutes time duration. This new protocol is based on a concept of non-linear voltammetry (NLV) with the use of a set of adaptation parameters related to the state of charge (SOC) and the state of health (SOH) of the battery. The fundamental of this concept is the foreseen relationship that the “product of”, “the rate of the change of drawn/charge-current (dI/dt)” and “the rate of the corresponding voltage change (dv/dt)”, is a “constant”, and expressed as (|dI/dt|)α * (dv/dt) = K. Here, the K is a constant and the “α” could be any non-zero value. The principle analogy here is when the battery voltage is increased, the resulted current accepted by the charge circuitry will naturally depends on the intrinsic kinetic-parameters which effects on charging at that peculiar moment of the battery system. Accordingly, in case of a rapid increase of current, the above relationship will regulate the voltage-change to be a smaller value, inversely proportional to the current ramp. Conversely, a small ramp in current will encourage this model to apply a large voltage change and accordingly let the cell to quickly push in to certain voltage regions which naturally favors in charging with high rates

In Universal Mobile Telecommunications System (UMTS), the extension of GPRS tunneling protocol called GTP’ is utilized to transfer the Charging Data Records (CDRs) from GPRS Support Nodes (GSNs) to Charging Gateways (CGs). To ensure that the mobile operator receives the charging information, availability for the charging system is essential. One of the most important issues on GTP’ availability is connection failure detection. This paper studies the GTP’ connection failure detection mechanism specified in 3GPP TS 29.060 and 3GPP TS 32.215. It is desirable to select appropriate parameter values to avoid false failure detections (e.g., temporary network congestions). It is also important to detect the true failures quickly, and after a true failure is detected, the GSNs can immediately re-direct to another CG. In this paper, we propose an analytic model to compute the false failure detection probability and the expected true failure detection time. The analytic model is validated against simulation experiments. Based on our study, the network operator can select the appropriate parameter values for various traffic conditions to reduce the probability of false failure detection and/or true failure detection time.

Due to the fact of the climate change, green resource gains its importance nowadays. Moreover, in order to conserve energy, reduce carbon emission, especially the transport emission, and concern with the high expense of gasoline, developed countries highly promote electric motors. Therefore, the convenience of charging stations is the key factor for consumers’ willingness to use electric motors. Charging stations for electric motors are highly different from gas stations for that charging stations require both quick and slow recharging zones. The slow charging posts are mainly set in parking lots, roadsides, office buildings or a community building area. The average time for slow recharging is over 3 hours while it only takes 30 minutes to obtain 80% of energy in quick recharging way. To date, most countries plan to build self-service recharging stations. In addition, with the concerns of safety for recharging and trade, convenience with APP, preservation and display on map, instant information provided such as recharging completion or problem notice, future expandable features such as the connection with intellectual network and the easiness of expand, the electric motors industry can be developed in a short time. Based on the features of electric-motors, this study mainly applies XMPP communication protocol with an embedded system in charging post and Server communication protocol to stimulate charging. In addition, the application of XMPP with card readers helps to inform users and server administrators as well as to set up a parameter in charging post.

Full textRecent advances in the fields of wireless energy transmission and batteries material offer new possibilities for managing the available energy in WSNs. In the first field, the technology of highly efficient wireless energy transmission was proposed for efficient, non-radiative energy transmission over mid-range. It has been shown that through strongly coupled magnetic resonances, the efficiency of transferring 60 watts of power over a distance in excess of 2 meters is as high as 40%. Industry research also demonstrated that it is possible to improve transferring 60 watts of power over a distance of up to one meter with efficiency of 75%. At present, commercial products utilizing wireless energy transmission have been available on the market. In the second field, ultra-fast charging was recently realized in LiFePO4 by creating a fast ion-conducting surface phase through controlled off-stoichiometry. These technologies lead the way towards a new paradigm for wireless sensor networks; the Wireless Rechargeable Sensor Networks (WRSNs), which consist of sensor nodes that may be either stationary or mobile, as well as few mobile nodes with high energy supplies. The latter, by using wireless energy transmission technologies are capable of fast charging sensor nodes. This way, the highly constrained resource of energy can be managed in great detail and more efficiently. Another important aspect is the fact that energy management in WRSNs can be performed passively from the perspective of sensor nodes and without the computational and communicational overhead introduced by complex energy management algorithms. Finally, WRSNs allow energy management to be studied and designed independently of the underlying routing protocol used for data propagation. The Problem. Let a Wireless Rechargeable Sensor Network consisting of a set of stationary sensor nodes and a special mobile node called Mobile Charger. The sensor nodes are deployed uniformly at random over a network area and propagate data to a Sink using a routing protocol. The Mobile Charger has finite energy supplies, that are significantly greater than those of a single sensor node, and is capable of charging the sensors. The problem we study is identifying best possible configuration of the Mobile Charger in order to improve energy efficiency and to prolong the lifetime of the network. Our Contribution. While considerable research efforts have been invested into energy efficient scheduling of the Mobile Charger, proposed solutions in the literature so far require a global knowledge of the state of the network. On the contrary, the solutions proposed in this work are fully distributed and adaptive, and rely solely on local information. Furthermore, our proposed algorithm for the Mobile Charger can be used in combination with any underlying routing protocol and adapts on the distribution of sensors in the network area. We identify and investigate the following trade-offs: i) how the total available energy of the network should be split between sensor nodes and the Mobile Charger ii) given that the energy the charger may deliver to the nodes is finite, whether each sensor will be fully or partially charged and iii) what is the trajectory the Mobile Charger should follow in order to charge the sensor nodes.
