A battery pack includes at least one battery module including a plurality of battery cells, and a module housing to receive the plurality of battery cells, at least one thermoelectric module disposed outside or inside of the module housing of the battery module and configured to generate voltage when a temperature of the battery module rises to a predetermined temperature or above, and an energy drain unit configured to discharge the battery module when a predetermined magnitude of voltage or above is applied from the thermoelectric module.

Battery pack and battery rack and energy storage system comprising the same

A battery management apparatus is discussed, and includes: a measuring unit connected to a battery and configured to operate in a measurement mode during a predetermined measurement time at each preset measurement cycle and measure battery information including at least one of voltage and temperature of the battery while operating in the measurement mode; and a control unit configured to operate in a communication mode during a preset operation time at each preset communication cycle, receive the battery information from the measuring unit while operating in the communication mode, set a next operation time point at which the measuring unit is to operate in the measurement mode based on at least one of the communication cycle and a measurement time, and change an operation time to operate in the communication mode at each subsequent communication cycle based on the measurement time.

Battery management apparatus and method

A data input scheduling apparatus that controls a vehicle battery and a relay for changing an electric connection between output terminals of the battery, and includes a detection unit for outputting an impact detection signal when an impact is applied to the vehicle and a control unit for outputting a relay-off signal to change the relay into an off state in response to the reception of the impact detection signal, the control unit outputting the relay-off signal according to a preset control cycle.

Data input scheduling apparatus

A master battery management unit including a sensing unit generating pack information of the battery pack, a first master power supply unit generating a first operating voltage using voltage of the battery pack, a communication unit outputting a first switching signal in response to the first operating voltage supplied from the first master power supply unit, a second master power supply unit generating a second operating voltage using the pack voltage in response to the first switching signal, and a control unit operating using the second operating voltage supplied from the second master power supply unit, and testing a preset item based on at least one of the pack information and module information.
