Special Issue Information

Dear Colleagues,

Although electrification of various modes of transportation has become tremendously popular in the last decade or so, the infrastructure to charge them is noticeably deficient. This Special Issue aims at addressing this burning issue by focusing on power converter topologies and control specifically applicable to futuristic fast charging systems as well as wireless (conductive, inductive, capacitive, and/or hybrid) charging systems. Wireless charger designs for varied modes of transport such as cars, bikes, buses, drones, aircrafts, ships, undersea vehicles, and metro/streetcars/railways are of particular interest. Critical issues such as inductive power transfer (IPT) coil design and capacitive power transfer (CPT) dielectric medium/transfer plate designs will be focused on. Futuristic designs and evolution of DC fast-charging infrastructures will also be looked at, including technologies addressing grid-connected (medium-voltage) converters, power quality issues, as well as power electronics interface for renewable energy/smart-grid-based chargers. Topics of interest include (but are not limited to):

  • Wireless and plugged charging power converter topologies;
  • Static and dynamic (in-motion) wireless charging;
  • Inductive and capacitive power transfer (IPT/CPT) coupler designs and compensation techniques;
  • Power converters and control for health-conscious fast charging;
  • Battery energy management systems and thermal management systems for extreme rapid charging;
  • Wide bandgap (WBG) devices (SiC and GaN) for extreme fast-charging converters and their control;
  • Electromagnetic inference (EMI) and electromagnetic compatibility (EMC) issues;
  • Autonomous vehicle-to-vehicle (V2V) charging;
  • Renewable energy/smart-grid-integrated chargers/converters;
  • Futuristic charging station infrastructure design and development;
  • Power electronics to solve grid-side power quality issues;
  • Standards and policies for plugged and wireless fast charging.

This paper deals with the estimation of core temperature (Tc) of a Lithium (Li) ion battery using measured ambient and surface temperatures. The temperatures were measured using thermocouples placed at appropriate locations. A second order thermal model was considered for the core temperature (Tc) estimation. A set of coupled linear ordinary differential equations (ODEs) were obtained by applying Kirchhoff’s current and voltage laws to the thermal model. The coupled ODEs were redefined in the discrete state space representation. The thermal model did not account for small changes in surface temperature (Ts). MATLAB/Simulink were used for modelling a Kalman filter with appropriate process and measurement noise levels. It was found that the temperatures closely followed the current patterns. For high currents, Tc dominated the surface temperature by about 3 K. Tc estimation plays a very important role in designing an effective thermal management and maintaining the state of health (SOH) during fast discharges under limits. Most of the battery management system (BMS) applications required Ts as the input to the controller. Hence, an inverse calculation for estimating Ts from known Tc was carried out and found to be reasonably accurate. It was found that the thermal parameter Cs played a major role in the accuracy of Ts prediction and must have low values to minimize errors. Full article
