In-situ determinationof the thermal parameters for lithium-ion batteries is important yet challenging. This paper presents and validates a method to simultaneously estimate multiple thermal parameters for large-format laminated lithium-ion batteries. In this method, a circular planar heater was attachedat the center of the battery surface while the temperature responses at multiple strategically chosen locations were recorded with thermocouples. The heat conduction was modeled based on a two-dimensional axially-symmetric model containing heat capacity, thermal conductivities, and interfacial thermal conductance. These thermal parameters were tuned till the differences between the simulated and measured temperatures reached the minimum using optimization techniques. The estimated heat capacityagreed wellwith the result measuredwith an accelerating rate calorimeter. Theproposed methodcanalso be usedto estimate the thermal parameters of other devices/structures consisting of a covering outside and heterogeneousmaterials inside.

An ultracapacitor equivalent circuit model and the procedure to identify its parameters is proposed and validated. The model, appropriated for hybrid electrical vehicle simulation, is experimentally validated under controlled conditions in laboratory and under real utilization conditions in a hybrid electric vehicle. The validation is performed with different ultracapacitor nominal values (583F-15V, 32F-270V and 16F-540V).

Electromagnetic interference (EMI) of electric vehicles will affect the sensitive devices, health of the passengers and power quality of the grid. In order to get interference characteristics in the energy dynamic processes, pulse width modulation (PWM) inverter and on-board charger are studied for interference source feature analysis. Then, the power battery is modeled as the main energy storage equipment and interference propagation paths in electric vehicles; the parameters of the model are identified through tests and measurements. Furthermore, the model is verified from two aspects: energy changing dynamic response and frequency features. Finally, interference characteristics are obtained from differential mode (DM) and common mode (CM) current analysis based on simulations and experiments.

Predicting the ageing behaviour of a lithium-ion battery is a challenging difficulty in plug-in hybrid electric vehicles applications. Invoking the expensive price of the energy density linked with considerable performances degradation over cycling, it is worth considering a battery lifetime optimization in the design process. The degradation will materialize by a capacity loss and an increase of the internal resistance. Capacity loss will affect the autonomy of the vehicle while an increase of the internal resistance will lead to an increase of the battery power losses and overheating. In the paper, the lifetime of a PHEV roadster battery pack is estimated by applying a real-life current discharge pattern, instead of the common ageing experiments based on constant current discharge patterns. A current cycle corresponding to a roadster power load has been used as input. This work involves an accelerated ageing experiment of individual LiFePO4 battery cells through cycling. The cycle applied is derived from a speed cycle comprised of three parts: urban roads, rural roads and highways. For more than 1400 cycles, the capacity, internal resistance, voltage, current and temperature have been monitored.

This paper presents an original control algorithm for a parallel plug-in hybrid-electric vehicle powertrain. Two operational strategies using this algorithm are designated as EV/CS (battery-only operation followed by charge sustaining operation) and CD/CS (charge depleting blended operation followed by charge sustaining operation) with the same control algorithm used throughout both. An algebraic mapping of three observable variables outputs a single motor torque-command that can either propel or regeneratively brake the vehicle. This mapping is on-line feasible in real time, avoiding the use of look-up tables or some computationally complex optimization approach involving searches over an admissible control space. Another important feature of this methodology is that the highly developed engine and transmission controls of non-hybrid powertrains are essentially maintained. Using a Simulink model, the fuel economy and SOC (state-of-charge) as a function of driving distance for both strategies are presented. Most importantly, results of recorded on-road SOC data are included that shows practicality on a real vehicle in a real driving situation over 96 miles. Also presented are simulated and real driving acceleration results.

This paper proposes a control strategy for high power factor without electrolytic capacitor in home appliance. The proposed system consists of single-phase diode rectifier, small film capacitor (14uF), three-phase voltage inverter and AC motor. In order to obtain a high power factor, this paper proposes a new control method that delays q-axis current compared with phase of grid voltage. The method is based on the field-oriented control and uses the space vector pulse width modulation (SVPWM). The simulation results illustrate the validity of the analytical approach and the efficiency of the proposed method.

State of health (SOH) estimation for Lithium-ion batteries is a core technology of battery management systems, which is a foundation of ensuring system's safety and reliability. An accurate SOH estimation reflects the present fraction of allowable performance left before the end of life. In this paper, quantization standards of SOH are introduced firstly and some suggestions are proposed to solve the inconformity issue of SOH definitions. Then the battery aging phenomenon is interpreted theoretically, which contains the analyses of the aging mechanism, the changes of parameters during aging processes and the factors of accelerating aging. Next, some main methods of the SOH estimation are summarized and compared with each other. And finally, this paper describes the development trend of SOH estimation algorithm.
