Series hybrid electric vehicle (SHEV) using multiple power sources such as engine-generator, battery and ultracapacitor requires the power control unit with high power density and reliable control operation. However, the manufacturing of each individual power converter has a demerit of a low power density inside the vehicle and great amounts of the power and signal cable wires. Also, it is difficult to implement an optimal power distribution and a fault management algorithm because of the communication delay. Therefore, this paper presents a design and power control algorithm of the integrated power converter of the series hybrid electric vehicle using multiple power sources. The design methodology of the integrated power control unit is firstly described, and then an efficient and reliable power distribution algorithm is presented. The design approaches are verified with the product-level and vehicle-level performance experiments of the 10-ton SHEV.

In this paper, the methodologies for obtaining the pulse power capability and utilizing it for power control logic in electric vehicle are proposed. There has been researches on pulse power, but the method of applying it to the vehicle control logic of the electric vehicle is not clearly mentioned. Thus in this paper, the definition of the lumped resistance and calculation method of the pulse power are described. The proposed method is systematically presented through a lithium-ion battery with a nominal voltage of 44V.

Objective : This is a case of a 19-year-old male patient who had been diagnosed with Underactive Neuropathic Bladder and complained of difficulties in voluntary urination. Method : Based on Korean medical practice, we considered the symptom of Underactive Neuropathic Bladder as the loss of sensation in the lower abdominal region (小腹不仁). Palmijiwhang-hwan (八味地黃丸), which contains Acontii Tuber(附子), was prescribed. Results : After two weeks of treatment, the symptom was effectively relieved and the total number of catheterization within the treatment period was reduced. The patient currently maintains normal levels of voluntary urination as we reported it in this study.
