Abstract: A battery energy storage system (BESS) and a method therefor is disclosed. The BESS includes a power converter system (PCS) for charging/discharging a battery including battery module(s) by using a superimposed control signal in which an electrochemical impedance spectra (EIS) reference signal for a state of health (SOH) evaluation of the battery is superimposed on a control signal for charging/discharging the battery. The EIS reference signal has a frequency selected for EIS. The BESS includes sensor(s) for detecting response data of the battery in the charging/discharging via the superimposed control signal. The BESS includes multiple levels of controller distributed in the BESS, the respective levels of controller communicating with each other. The response data being accessible to the respective levels of controller. The SOH evaluation is conducted in such a dynamic manner that the response data is processed at any level of controller to obtain a result.

Abstract: Structural members and methods for manufacturing a plastic-based, bulk, antimicrobial structural member of a robot. Such bulk antimicrobial plastic solution can meet the hygienic requirement and the mechanical performance requirement of a structural member of a robot simultaneously. Meanwhile, it may reduce the overall weight of the robot.

Abstract: A thermochromic polymer composition including a base polymer material; a temperature sensitive material, which changes a color of the thermochromic polymer composition in response to a temperature change; and a stabilizer, which enhances stability performance of the thermochromic polymer composition. The thermochromic polymer composition which has a good thermochromic performance and good thermal performance and thus could provide a visible indication of the overheat condition. An electrical device is formed from the thermochromic polymer composition. A further embodiment of the process for preparing the thermochromic polymer composition and forming the electrical device.

Abstract: A thermochromic electrical device is made of thermochromic plastic material and has a visual indicator pre-printed with regular print or ink to allow visible warning of a scalding situation when the thermochromic plastic portion fades from its original color to leave the warning visible. The electric device may be any one of, for example, a cable tie, a cable connector, a terminal connector, a splice connector, and a cable jacket.
