Summary: The electric vehicle, when managed by an aggregator, is a suitable candidate for participating in demand response in power system operation. An optimal scheduling algorithm is necessary to maximize the aggregator's benefit, considering the benefits of distribution system, aggregator, and EV users. This study defines the benefits of the three parties and tests the optimal scheduling system to analyze the impact of aggregator facilities, technology, and operation mode on the benefits.

Summary: This study systematically discusses a vehicle design process with lightweight as the design objective, focusing on the analysis of the designed frame. The research calculates the load condition of the vehicle under different circumstances, analyzes the stress on components, and designs the steering geometry, turning angle, and radius. Rigidity analysis and finite element analysis are used to determine the stability of the vehicle in motion, while experimental modal analysis and finite element method are mutually verified to ensure consistency between the model formation and the real frame in the electric vehicle manufacturing process. In terms of circuit design, overcurrent protection is provided for the main power supply using no-fuse switches and fuses, and a combination of chip, optically coupled circuit, current sensor, and restriction controller is used for further protection and control.

Summary: This study proposes a new model based on measured harmonic spectra of electric vehicle chargers to evaluate their impact on the power quality of low voltage networks. By using Gaussian Mixture Models to represent the harmonic spectra, precise and efficient electrical characterization is achieved. Results show that with increasing penetration levels of electric vehicles, network chargeability and voltage unbalance increase.

Summary: The transportation sector plays a major role in greenhouse gas emissions, making it crucial to study the impact of electric vehicles on the economic and environmental performance of developing countries. A survey conducted in Pakistan revealed that users welcome the adoption of hybrid and electric three-wheelers due to increased economic benefits. Despite the higher initial capital cost, hybrid or electric three-wheelers can significantly improve monthly earnings by 50% and lower CO2 emissions by 3-6 tonnes per year per vehicle.

Summary: Introducing battery electric vehicles quickly to the market can lead to errors and recalls, which can be avoided by simulating BEVs in an integrated manner. By developing a drivetrain model integrated with cabin, battery, and power electronics models, key system-level outputs are obtained to identify simple energy-conscious actions and quantify energy savings. The integrated model is validated at both component and system levels.

Summary: Conventional electric vehicles and hybrid electric vehicles can only store a small part of kinetic energy, necessitating the use of a flywheel energy storage system (FESS) for regenerative braking. Experimental studies show that the proposed purely electrical power transmission system for FESS is more efficient, lighter, cost-effective, requires less space, and maintenance-free compared to traditional mechanical systems.

Summary: China has become the largest electric vehicle market globally, resulting in increased attention towards the energy and climate issues of the EV industry throughout its life cycle. This study utilized a self-designed life-cycle analysis tool and up-to-date database to analyze the energy consumption and greenhouse gas emissions of various types of electric vehicles and internal combustion engine vehicles. The findings show that due to battery installation, EVs emit significantly more GHG emissions in the vehicle cycle compared to ICEVs. However, the low emissions in the fuel cycle offset the surplus emissions in the vehicle cycle, resulting in a 18.3%-22.6% reduction in life cycle GHG emissions compared to ICEVs. The development of non-fossil power sources can further reduce GHG emissions of EVs.
