Abstract: A bus bar assembly and current measuring device configured to reduce measurement errors through linearity compensation and temperature compensation for the difference in values of two or more measured currents, thereby achieving high-accuracy current measurement, is presented. The present invention discloses a bus bar assembly including: a first conductive plate and a second conductive plate each composed of a plurality of parts; and an insulator formed between the first conductive plate and the second conductive plate, wherein a common first terminal hole is formed at one end of the first conductive plate, one end of the second conductive plate, and one end of the insulator, a common second terminal hole is formed at respective opposite ends of the first conductive plate, the second conductive plate, and the insulator. According to the present invention, stable and highly reliable current measurement is possible through multiple shunt resistors based on a redundancy design.

Abstract: The present invention provides a battery monitoring method, which is performed by a battery monitoring device, including: measuring a first voltage drop across both ends of a first shunt resistor of a bus bar electrically connected to a battery and a second voltage drop across both ends of a second shunt resistor, which is in parallel or serial connection with the first shunt resistor; calculating a first current and a second current flowing, respectively, through the first shunt resistor and the second shunt resistor using a first voltage drop value and a second voltage drop value; and determining a state of the battery using a difference between a first current value and a second current value. According to the present invention, it is possible to increase the reliability of monitoring information related to the battery's state by utilizing current values that have undergone linearity compensation and temperature compensation.

Abstract: Disclosed is a method for producing anti-E. coli O157 antibodies. Anti-E. coli O157:H7 antibodies are produced in egg-laying hens and isolated from the eggs. E. coli O157:H7 is cultured in a brain heart infusion broth and killed by the treatment with hot water for 5-10 min. After being collected by centrifugation, the dead bacteria is homogenized. Serving as an antigenic material, the bacterial homogenate is injected into egg-laying hens to induce antibodies against E. coli O157:H7 in the eggs. The induced antibodies are isolated from the yolk of the eggs and the eggs containing the antibodies against E. coli O157:H7 can be utilized, in their entirety, for foods. Alternatively, the yolks are separated from the eggs and freeze-dried. The resulting dried egg component can be applied to processed foodstuffs, alone or in combination with whole eggs. Since the antibodies against E. coli O157:H7 are contained in frozen eggs, it is very convenient to store the antibodies.
