Abstract

The present invention relates to a battery pack status parallel monitoring device comprising: a battery pack comprising a plurality of battery cells; a cell monitoring unit for measuring a state of the plurality of battery cells; a BMIC for generating a diagnostic signal indicative of the state of the battery pack through the cell monitoring unit; a main MCU for receiving the diagnosis signal; andan auxiliary MCU for receiving the diagnosis signal and transmitting and receiving the main MCU data, wherein the battery pack status parallel monitoring device comprises: a data line for connectingthe BMIC and the main MCU to each other; a parallel line connected in parallel with the data line; and a communication monitoring unit connected to the parallel line for monitoring data transmitted and received between the BMIC and the main MCU, and for transmitting the monitored data to the auxiliary MCU.

Description

technical field [0001] The present invention relates to a battery pack state parallel monitoring device, and more particularly to a simple parallel structure comprising a parallel line connected to a communication line connecting a communication unit and a main MCU to each other, and monitoring through the parallel A communication monitoring unit that transmits / receives data between the communication unit and the MCT, and a battery pack state parallel monitoring device that can realize an advanced security mechanism. Background technique [0002] Recently, research and development of secondary batteries have been actively performed. Here, the secondary battery which is a rechargeable battery represents both conventional Ni / Cd battery and Ni / MH battery and the latest lithium ion battery. Lithium-ion batteries among secondary batteries have the advantage of high energy density compared to conventional Ni / Cd batteries or Ni / MH batteries. In addition, lithium ion batteries can...
