Abstract: Disclosed herein is a technique for determining degradation of a high-voltage battery of a vehicle. More specifically, variations in charge capacity with respect to a predetermined variation in voltage of a high-voltage battery that is currently being slowly charged are obtained depending on degradation degrees of the high-voltage battery. A vehicle equipped with a high-voltage battery having a specification identical to those of the high-voltage battery is used to acquire a charge capacity and a voltage of the high-voltage battery that is currently being slowly charged. A variation in charge capacity with respect to the predetermined variation in voltage is calculated from the charge capacity and the voltage. The variation in charge capacity with respect to the predetermined variation in voltage is compared with the variations in charge capacity with respect to the predetermined variation in voltage depending on the degradation degrees, thus determining a relevant degradation degree.

Abstract: A safety apparatus of a battery module for a vehicle is provided. The apparatus includes cell terminals disposed in battery cells disposed in a row. A safety bus bar electrically connects two cell terminals disposed diagonally in two battery cells adjacent to each other among the battery cells. In addition, the safety bus bar maintains the electrical connection when the battery cells are not expanded and opens a circuit to prevent electricity from flowing when at least one battery cell is expanded.

Abstract: The disclosure is related to a real-time analysis of social network service (SNS) data associated with a multimedia content service. Particularly, SNS users may be classified into active SNS users and non-active SNS users, based on an SNS activity amount. SNS data collection/analysis periods may be differently determined according to SNS user types. Furthermore, a statistical analysis result of the SNS data may be directly or indirectly provided to one or more user equipment such that the SNS data analysis result can be displayed along with a corresponding multimedia content.
