摘要： The present invention relates to a system for protecting a battery, and to a battery protecting system, which obtains state information of a battery through two different state obtaining units and diagnoses whether the battery has a problem based on the two elements of state information obtained through the two state obtaining units and reference state information, thereby more certainly diagnosing a state of the battery and stably protecting a load from the battery in the problem state.

摘要： A fuse control system and method using a defective mode detection, in which an overcurrent protective fuse and a signal fuse capable of performing a function under various conditions in order to protect a circuit are integrated. Thus, it is possible to protect the circuit even in states such as overvoltage, a high temperature, a low temperature, and other dangerous states in addition to an overcurrent state and a short-circuited state. In addition, it is possible to reduce a wide design space and design cost which result from various kinds of fuses being used in series, and to simplify a circuit configuration. Consequently, since circuit resistance is reduced, it is possible to have a positive influence on a battery.
