A Review of Hybrid Technology Applications and Development Trends

Abstract

Currently, fossil fuel combustion and carbon emissions are triggering an increasingly serious greenhouse effect, which, coupled with the energy crisis, requires the transformation and upgrading of power modes for vehicles, transportation and engineering instruments. Due to the limitations of batteries in terms of energy density and range, pure electric drive cannot well meet the daily driving needs. The central idea of hybrid power is to make the internal combustion engine (ICE) and electric motor (EM) work together to improve energy utilization, energy saving and at the same time solving the problem of short range of electric vehicles. Vehicles and instruments utilizing hybrid powertrains have low emissions, low fuel consumption levels, high fuel economy, and energy recovery at the same time. This paper provides an overview of the structure and energy forms of hybrid technology and their applications, design simulations done by previous authors, optimization strategies, and summarizes the future trends of hybrid technology.
