Abstract
This study presents the improvement of energy efficiency and operating time of mini-loader vehicles by integrating the power system of internal combustion engines (ICE) and electric motors (EM). The hybrid powertrain was developed based on the belt-starter generator (BSG). The BSG system enabled us to choose optionally the ICE or the EM mode according to the power demand in different usage scenarios. The required power specifications were evaluated. The equipment in conformity with specification was then tight-stacking installed in the limited space of the mini-loader. Therefore, the mini-loader ably passes across a 770 mm width door. In the situation of consumption of the same amount of gasoline, the hybrid power mode can increase the operating time by 30 min. In addition, its power output can be satisfied to override 140 mm high short steps, cross a 300 mm trench, and climbing a 30% slope. In particular, using electricity as a power source can reduce carbon emission.
Highlights
Climate change-related disasters caused by the greenhouse effect, in terms both of quantity and intensity, have been increasing year on year
The motor module, the battery module, and the controller module are mounted on the mounted on fuel the engine, platformthe to motor complete the mechanical of the power system
The working environment is more operator-friendly, and the system can operate in narrow spaces
Summary
Climate change-related disasters caused by the greenhouse effect, in terms both of quantity and intensity, have been increasing year on year. Mini-loader vehicles, which are used in agricultural operations have the potential to be refitted as multi-purpose disaster relief machines [1]. The mini-loader (C85 Series, CORMIDI, U.S.) can be used as a tool vehicle for disaster relief, transporting goods, and excavation operations by consuming gasoline as fuel. Replacement modules are provided as tools to meet the needs of users and expands the operation category and scope of mini vehicles. Another commercial loader (CINGO, MERLO, Italy) strives to satisfy consumers’ requirements for a single vehicle with more suitable work
