A nonaqueous electrolytic solution for a secondary battery containing an electrolyte, a solvent and methyl difluoroacetate as an additive in an amount of not less than 0.05 part by mass and not more than 10 parts by mass based on 100 parts by mass of the whole solvent.
摘要:
An inspecting ECU 4 and a GD substrate 3 are connected to an inverter circuit 100 for converting a power to be supplied from a voltage source 2 and outputting the converted power to a motor 5, and switch a conducting state of each of the elements in the inverter circuit 100. A conducting state of the element is switched in accordance with a driving condition for inspection corresponding to a whole active region of the element in a state that an inspecting load 50 is connected to the inverter circuit 100. A phase current flowing in the element and a voltage between terminals of the element through a voltage detector 11 and a current detector 12 are detected to obtain a correlation of an ON time of the element and a phase current value based on the current and the voltage which are detected.
