Special Issue Information

Dear Colleagues,

The automotive industry is developing a range of electrically-powered, environmentally friendly vehicles such as hybrid vehicles (HV), plug-in hybrid vehicles (PHV), full electric vehicles (EV), and fuel cell vehicles (FCV) to help reduce tailpipe CO2 emissions and prevent air pollution. This is driving vehicle electrified power proportion system development and research activities both in academia and industry. However, in order to enhance the full performance and cost reduction of such electrified powered vehicles, we are in no doubt that the power electronics researchers and engineers who are developing high performance power electrics subsystems will have to contribute to expansion of the whole vehicle performance and usability for customers, simultaneously. The research fields and topics for this Special Issue include all power electronics-related technologies other than vehicle proportion systems. We define a power electronics system as a system handling electric power of more than approximately 1 kilo watt. We propose that this Special Issue will cover all areas of power electronics subsystems and their components, for example, systems such as charging systems, high voltage battery systems, subsystems with motor(s) and electric power conversion systems and components such as power semiconductor devices, power modules, passive components, tools, sensors, connecters, cables, relays, circuits topologies, algorithms and software. Vehicle type is not limited, namely this special issue accepts subsystems for both conventional vehicles and electrified vehicles. And furthermore, system voltage is not also limited, namely all 12V, 48V and HV are welcome.

This paper first presents a new powertrain based on a two-battery High-Efficiency Energy Conversion System (HEECS) chopper that is suitable for electric vehicles (EVs). The HEECS chopper is based on the principle of a partial power conversion circuit, and the overall efficiency is over 99% in a wide load range. The efficiency of this powertrain was measured in the steady state by two types of powertrains, a non-chopper powertrain and an HEECS chopper-based powertrain, using a motor test bench. On the basis of these data, several driving tests, such as the Worldwide-harmonized Light vehicles Test Cycle (WLTC), were simulated, and four driving cycle patterns were included. A 6.4% reduction in energy consumption was observed in WLTC low mode compared with the energy consumed by the non-chopper powertrain in the experiments. Thus, the HEECS chopper-based powertrain is more suitable for low-speed driving ranges than high-speed ranges. Full article
