MODULE TYPE STORAGE BATTERY MONITORING SYSTEM CONNECTED WITH CAN COMMUNICATION

摘要

The present invention relates to a system for monitoring the state of a battery and, more specifically, to a system for monitoring the state of a battery of a module structure connected through CAN communication capable of measuring important parameter, such as internal resistance of a battery, online in a state that dozens of battery systems connected in series used for communication network power equipment or emergency power equipment operated around the clock are not separated from an operation system. The system for monitoring the state of a battery comprises: a measurement module including a CPU and connected to the batteries in parallel to monitor the state of the batteries; and a control module connected with the measurement module through CAN communication of two core twist pair wires to receive the state of batteries from the measurement module.
