摘要

Power electronics technology continues to evolve, particularly in the automobile industry, with the aim of reducing fuel consumption and the environmental burden. This technology was adapted for a hybrid hydraulic excavator, the SK200H-10, equipped with a lithium ion battery, as introduced in this paper. A continuous engine assist has been realized for the hydraulic excavator by effectively using the regenerative energy generated during slewing deceleration, due to the large inertia of its slewing body, and by adopting a lithium ion battery with high output and large capacity. As a result, the fuel consumption of the excavator has been reduced significantly. The scrap handling machine (with magnet), the SK210DLC-10, has the same generator motor as SK200H-10 and applies a hydraulic excavator with a totally new power generation system, which was formerly based on a hydraulic pump. This machine enjoys a remarkably increased magnetic attraction and considerably reduced fuel consumption, thanks to the reduced energy loss during power conversion.
