Patent number: 11899073Abstract: An impedance measurement device of the present disclosure includes: an electrochemical energy device; an amplifier connected to each connection terminal of the electrochemical energy device and configured to amplify a signal introduced into a wiring; and a main board configured to receive the signal from the amplifier and measure an impedance. Accordingly, the present invention has advantages in that high resistance to electromagnetic interference may be achieved by disposing a preamplifier close to a terminal of an electrochemical energy device to amplify only the signal without amplifying a noise introduced into a wiring.Type: GrantFiled: September 22, 2020Date of Patent: February 13, 2024Assignee: Mintech Co., LTDInventors: Hyung Bin Son, Young Jae Lee, Gyeong Rin Choi, Young Jin Hong

Patent number: 11391783Abstract: Provided is a method for diagnosing a state of reusable (SOR) of a battery and, more specifically, to a method for diagnosing an SOR of a battery, the method being capable of diagnosing the overall state of a battery during battery reuse by separately diagnosing a state of health (SOH) and a state of power (SOP) of the battery. The method for diagnosing a state of reusable (SOR) of a battery according to the present invention includes: estimating a state of charge (SOC) according to a change in an open circuit voltage (OCV); estimating a state of health (SOH) by using the SOC; calculating a state of power (SOP) in consideration of an output of a current battery; and calculating the SOR by using the SOH and the SOP.Type: GrantFiled: September 5, 2018Date of Patent: July 19, 2022Assignee: Mintech Co., Ltd.Inventors: Hee Kyung Myung, Jun Hee Lee

Patent number: 9944562Abstract: Ceramic granules having high reflectivity and a preparation method for the same comprise sand core particulates and at least one coating thereon, wherein said sand core particulates contain calcined tobelite that is obtained by calcining the tobelite ore at 700-1200° C.; and said sand core particulates are coated with an inorganic coating, and then calcined at 800-1200° C. to obtain ceramic granules. Said ceramic granules have a particle size of 0.1-3.5 mm, and have a solar reflectivity SR of not lower than 80% and a staining index DL* of lower than 6%. Said ceramic granules produce a solar reflectivity of not lower than 70% when being applied to the asphalt roll/sheet and a solar reflectivity of not lower than 72% when being applied to the polyurethane foam sheet.Type: GrantFiled: February 1, 2016Date of Patent: April 17, 2018Assignee: Shijiazhuang Nikka Mintech Co., Ltd.Inventors: Zhijie Li, Hongwei Lu
