Abstract

The invention discloses a monitoring system of the battery state applied to an online storage battery pack. The system comprises a data acquisition module, an excitation generation module, a synchronous acquisition signal line, a synchronous channel enabling line, an excitation line and a measuring line, the data acquisition module comprises a switching unit, an isolation unit, a voltage processing unit, an acquisition unit, a single-chip microcomputer, a communication unit, an isolation power supply and an internal resistance processing unit, and the excitation generation module comprises anisolation power supply, an excitation unit, a single-chip microcomputer, an isolation unit and a switching unit. According to the system, synchronous switching of excitation and acquisition is realized through linkage control of the data acquisition module and the excitation generation module, battery information of storage batteries is acquired in real time to monitor the storage batteries in real time, the state of each storage battery is understood, a high-current discharging test of the storage batteries is avoided, the workload is reduced, the work efficiency is improved, the wiring is simple, and the cost is effectively reduced through reuse of devices.

Description

technical field [0001] The invention belongs to the technical field of accumulators, in particular to a monitoring system applied to the state of an on-line accumulator battery. Background technique [0002] The battery status monitoring of the existing battery pack under the online floating charge state often adopts the offline high-current discharge method, and the battery parameters are collected once during the quarterly routine inspection to judge the quality of the battery. The discharge test requires It consumes the workload of the staff, affects the normal life of the battery, and cannot grasp the status of the battery in real time. When an emergency occurs, it is easy to cause fire and other impacts; [0003] For the accuracy of measurement, the current online battery monitoring devices mostly adopt modular design. The power supply of each module is obtained from the measured battery. The voltage and internal resistance parameters of the battery, more batteries wil...
