Abstract

The invention belongs to the technical field of storage battery management and provides a storage battery online monitoring system and a monitoring method thereof, wherein the system comprises at least one storage battery monitoring terminal and a storage battery monitoring center, the storage battery monitoring terminals are arranged at corresponding monitoring points, connected with storage battery poles and used for collecting ripple voltage of storage batteries; and the storage battery monitoring center comprises a ripple signal injection module which is used for injecting ripple current to the storage batteries synchronously, and meanwhile, the storage battery monitoring center collects the ripple current on a return circuit of a storage battery group and calculates and displays the internal resistance of corresponding storage batteries according to the ripple voltage and the ripple current. According to the storage battery online monitoring system and the monitoring method thereof, as the storage battery monitoring terminals used for the ripple voltage collection of the storage batteries are distributed at various monitoring points, and the collection of the ripple current is completed independently by the storage battery monitoring center, the situation that the collection of ripple voltage and ripple current is carried out by the same monitoring module is avoided, the waste of resources is reduced, and the cost is reduced on the premise of ensuring the accuracy.

Description

technical field [0001] The invention belongs to the technical field of storage battery management, and in particular relates to an online storage battery monitoring system and a monitoring method thereof. Background technique [0002] The battery online monitoring system is a system that monitors the performance of the battery by collecting and analyzing the battery parameters of the battery. The battery parameters generally refer to the battery internal resistance, terminal voltage, temperature and operating current. [0003] When the battery on-line monitoring system provided by the prior art monitors the internal resistance of the battery, the monitoring module collects the ripple voltage and ripple current on the battery, and then divides the ripple voltage by the ripple current to obtain the internal resistance of the battery . However, since the collection of ripple voltage and ripple current is realized by the same monitoring module, if the monitoring module is far ...
