Electric Vehicle Charging System and Infrastructure
Speaker: Ching-Yen Chung
The concept of the Electric Vehicle (EV) can be traced back more than 100 years ago. Inevitably, the EV will become mainstream transportation soon as governments around the world have issued gas car bans over the coming years or decades. When it comes to EVs, the charging issue is one of the common reasons the consumers feel uncomfortable, which is getting relieved with the EV charging stations becoming commonplace. The modern EV charging technology involves the lower level, covering the charging protocols, power electronics, and battery management, and the higher level—so-called Smart Charging System. Today’s talk first comes with a brief history of EVs, then comes the charging technologies on EV and EV charging stations. Last but not least, the Smart Charging System will be addressed.
Ching-Yen Chung: Dr. Ching-Yen Chung received his Ph.D. degree from the University of California, Los Angeles (UCLA) in 2014, specializing in Smart Electric Vehicle (EV) Charging Infrastructure. He worked as a Postdoctoral Scholar/Staff Researcher in Smart Grid Energy Research Center (SMERC) at UCLA from 2014 to 2020. Meanwhile, he cofounded MOEV Inc, a Smart EV charging solution company, with his advisor and served in the Hardware Lead role. In 2020, Dr. Chung joined the EV Industry when it became more prospective and promising as governments had issued gas car bans over the coming years or decades. He played various roles as Mechanical Engineer at Atlis Motor Vehicles, Control Systems Engineer at INDI EV, and Charging System Engineer at Canoo. His pioneering work at UCLA, allowing an EV charger to charge multiple EVs simultaneously, successfully solved the problems of the lack of infrastructure investment and underutilization of the chargers. His industrial experiences covered the charging protocols, power electronics, and battery management on EVs and EV charging stations. There are three patents in data analysis/predictions on energy management and EV charging attributed under Dr. Chung’s name.
The Climate Resilient Grid
Speaker: Erik Takayesu
Climate change is already impacting the electric system in various ways. In California, we are in the driest period in the last 1200 years, leading to more significant wildfires. As we look forward into the future, grid and community resiliency will be further impacted by increasing temperatures, sea level rise, droughts, wildfires, and more precipitation that requires future adaption and mitigation strategies. This presentation will cover what SCE has been doing in recent years to mitigate the impact of wildfires, and as we look into the future, will discuss the grid technology and architectural changes needed to modernize and build a more resilient system while enabling decarbonization.

Port of Los Angeles Resiliency in Capital Improvement Projects
Speaker: Adrienne Fedrick Newbold
The Port of Los Angeles continues to develop and adapt capital improvement projects to remain resilient to Sea Level Rise. As global sea levels continue to rise, shoreline assets become more vulnerable to increase in the frequency and magnitude of coastal flood events. Sea level rise is a significant risk that can have a long-term impact on business operations as well as international cargo; therefore, the Port is taking a proactive approach to address the risk when investing in new infrastructure to avoid costly future improvements. The presentation provides project examples and methodology taken to implement adaptation strategies to maintain resilience at the nation’s leading seaport. Resiliency strategies include updating governmental policies, implementing initiatives including regional and global collaboration, monitoring, and infrastructure development.
The basis for the resiliency implementation is The Port of Los Angeles Sea Level Rise Adaptation Study, which evaluated Port assets including Cargo wharves and miscellaneous operations, critical facilities, transportation (rail/roads), community assets, and natural habitats. The Port of Los Angeles study included the development of sea level rise maps showing exposure for years 2030, 2050, and 2100, a vulnerability assessment, and development of adaptation strategies.

The Electric Conversion of Commercial Truck
Speaker: Michael Li
Many states and nations have set targets and goals to phase out the sale of internal combustion cars. By 2035 100% of new cars and light trucks sold in California will be zero-emission vehicles. While everyone knows the whole automotive industry is making a turn, challenges also unveiled. Recently, the supply of EVs and the price of EVs are the two major issues received most complains. To fill in the gap of technology transition in automotive industry, especially in medium and heavy duty trucks, Evolectric brought a creative and highly efficient solution that converts existing trucks to electric powered through modularized platform. Today’s presentation will introduce the electric powertrain platform of Evolectric and the conversion process.
Michael Li: Michael is a subject matter expert with over 15 years of experience in the field of vehicle electrical architecture design, model-based design, vehicle controls programming, firmware support, powertrain control and calibration and prototype/R&D systems. He most recently worked with INDI EV in an EE Architect leadership position. Previously, he worked at Phoenix Motorcars and was a key stakeholder in helping them integrate their first direct drive powertrain system. Michael is responsible for driving Evolectric’s vehicle and battery controls and electrical integration strategies. He has a Master’s of Science Degree in Electrical Engineering along with a Bachelor’s of Science Degree in Electric Engineering.
Battery Systems Modeling & Simulation
Speaker: Chirag Patel
Developing battery systems for modern electric vehicle or stationary energy storage system applications requires a cross-functional team of engineers. Design challenges arise at all stages of the V-cycle, and a range of simulation tools are necessary to study the system and onboard software. In this presentation, MathWorks will show how to use system simulation tools to create accurate models of battery system and verify that the design meets the system level requirements. We will describe detailed models of battery pack and software algorithms of battery management system, that forms the closed-loop simulation framework necessary to evaluate the battery performance over a range of operating conditions. We will show software-in-loop and hardware-in-loop testing methods to gain confidence after every design iteration.
Variable Frequency Drive Modeling & Simulation
Speaker: Saleh Al Jufout
The inverter in an electric vehicle (EV), which is also called a variable frequency drive (VFD), is used to control the speed of the induction motor that drives the EV. This contribution describes a computational model and simulation on MATLAB/Simulink of the solid-state variable-frequency induction motor drive. The output voltages applied to the terminals of the induction motor can be, in general, given according to voltage-versus-frequency patterns of constant V/f, V/f2, and V/f1/2. This model has been developed for constant V/f for both transient and steady-state conditions analyses. The waveforms of the voltage, current, electromagnetic torque, and speed of the motor during acceleration and deceleration can be illustrated and analyzed.
