Method for determining deterioration of accumulator battery, method for measuring internal impedance of secondary battery, equipment for measuring internal impedance of secondary battery, equipment for determining deterioration of secondary battery, and power supply system

A method for determining deterioration of accumulator battery hooked up with loads in a system based on results of measuring internal resistances of an accumulator battery, the method comprising the steps of; predetermining as a specified temperature a temperature at which the deterioration of the accumulator battery is determined; calculating in advance temperature correction coefficients of the internal resistances from changes of the internal resistances depending on temperatures; predetermining resistance-voltage conversion factors to convert between the internal resistances at the specified temperature and terminal discharge voltages of the accumulator battery which are obtained at the specified temperature under a condition of flowing predetermined discharge currents from the accumulator battery; measuring the internal resistances of the accumulator battery and temperature of the accumulator battery at an internal resistance measurement; converting the measured internal resistance values into the internal resistance values at the specified temperature with use of the temperature correction coefficients of the internal resistances; converting the internal resistance values at the specified temperature into the terminal discharge voltage values of the accumulator battery at the specified temperature with use of the resistance-voltage conversion factors; and determining whether the accumulator battery is deteriorated or not by means of comparison of the terminal discharge voltage values of the accumulator battery at the specified temperature and a predetermined threshold value as a deterioration judgment standard.

The invention relates to a method for die-free fused deposition modeling of a part or a die, which belongs to the method of die-free modeling, and solves the problems of falling, flowing and collapsing of fusing material in the process of support-free and die-free fused deposition modeling of the existing method. The method comprises the following steps: (1) hierarchy slicing processing is performed to the three-dimensional CAD model of the part or the die; (2) a computer generates numerical control codes required by the shaping of each hierarchy according to the hierarchy slicing data and the characteristics of the slicing size and shape of each hierarchy; and (3) numerically controlled gas-shielded welding arc or laser bean is adopted to fuse and shape the fusing material on the base plate in sequence according to the numerical control codes of each hierarchy, until the requirements on the size and the surface of the part or the die are met; simultaneously, electromagnetic field acting on the fusing material in the melting bath is generated through an electromagnetic device. By adopting the method, the part or the die made of metal, intermetallic compound, metal ceramics, ceramics and functionally gradient material can be quickly obtained with low cost and high quality.
