The increasing popularity of electric vehicles presents both opportunities and challenges for the advancement lithium battery technology. A new longitudinal-flow heat dissipation theory cylindrical batteries is proposed in order to increase energy density uniform temperature performance lithium-ion packs while also shrinking their size by roughly 10%. First, a genetic algorithm used identify si...

Electrified vehicles on the market today all use the classical two-level inverter as the propulsion inverter. This thesis analyse the potential of using a cascaded H-bridge multilevel inverter as the propulsion inverter. With a multilevel inverter, the battery is divided into several parts and the inverter can now create voltages in smaller voltage levels than the two-level inverter. This, amon...

Introduction: In recent years, China has paid high attention on urban energy innovation, trying to achieve a win–win situation between environmental protection and development, it formulated series of policies promote innovation. Methods: Taking China’s new demonstration city (NEDC) policy as an example, this paper empirically investigates the impact PM2.5 by using difference-in-differences (DI...

Pollution reduction related to combustion engines is considered be an important issue around the world. Hydrogen as additive energy has been utilized for alternative fuel since it need not require any modification. Particularly, a sustainable option diminishing petroleum dependence and air pollutant emissions. In this study, we investigated tailpipe emission with hydrogen addition different dri...
