在规模经济与范围经济的时代背景下,混业经营成为了一种宏观发展趋势.金融控股集团作为混业经营的一种主要表现形式,其较大的经营规模、多元化的金融服务等特点,使得金融控股集团的风险防范问题愈发令人担忧,如何加强对金融控股公司的监管成为了当下反复探讨的一个话题,如何定位金融控股集团的法律地位也成了立法机关近年来思量的问题.本文主要从金融控股集团的界定入手,分析金融控股集团当前监管错位等问题,结合国内外的监管体系的理论研究,对国内金融控股集团的监管体系进行外部设计.

To optimize and improve the performances of balancing system for Li Fe PO4 battery stacks in electric vehicles, this paper proposes a new balancing topology based on a well known Buck-Boost circuit, which can reduce the number of switches, balancing time and losses. The switch inductance modules are substitute for inductors, which overcome the disadvantages of traditional balancing circuit by controlling the relay in modules. It can limberly change the structure of circuit, and decrease the average step of chare transfer. The comparative and experimental results of balancing operation of a pack of six cells in electric vehicle show that the optimized Buck-Boost circuit reduces the number of switches, improves the balancing speed 27% and balancing efficiency.

In order to improve life cycle and safety of underwater energy storage equipment,the research provides a smart battery management system (SBMS) for power lithium iron phosphate (LiFePO4) stack,and focuses on the cells equalization circuit.Two optimized schemes have been proposed for the Buck-Boost circuit based on inductors in order to improve performance of the equalizing time and the efficiency.The fuzzy current controller is used in system.A constant current charge-discharge experimental study is done on the underwater LiFePO4 stack and comparisons among the performances of three equalizing schemes are carried out.The optimized balancing scheme is implemented on a small electric vehicle,which verifies that the battery stack usage capacity has been improved.

An improved method of balancing circuit is presented considering the problem of balancing speed slow and high losses in Buck-Boost circuit for serially connected battery stack. Different balancing schemes are designed based on Li Fe PO4 battery stack in laboratory. The improved scheme control is integrated, focused on the effect on the improvement scheme to balancing speed and loss based on the battery practical model.The simulation and experiment results show that the optimized balancing control system decrease the balancing time and reduce the loss.
