[0022] figure 1 It is a diagram showing a configuration example of the battery system 200 according to the first embodiment. The battery system 200 in this embodiment may include a plurality of battery modules MDL1 - 1 to MDLm-nm and the wiring diagnosis device 100 , but is not limited thereto. The plurality of battery modules MDL1 - 1 to MDLm-nm and the wiring diagnosis device 100 can be connected via a first communication line DC and a second communication line BS forming a communication channel (indicated by ch in the figure). Here, the communication channel is a group of communication groups formed by connecting the wiring diagnosis device 100 and some or all of the battery modules MDL1 - 1 to MDLm-nm by the first communication line DC and the second communication line BS. Hereinafter, when a battery module is not distinguished from other battery modules, it is simply expressed as a battery module MDL.

[0081] Hereinafter, 100 A of wiring diagnostic apparatuses of 2nd Embodiment are demonstrated. In the wiring diagnostic device 100A of the second embodiment, the difference from the first embodiment is that a series of information is not set for each battery module MDL. Therefore, the description will focus on this difference, and the description of the common parts will be omitted.

[0082] Figure 10 It is a figure which shows an example of the structure of 100 A of wiring diagnostic apparatuses of 2nd Embodiment. In the diagnostic processing unit 110A in the second embodiment, the series of information setting units 114 of the above-mentioned functional units are omitted. In this case, the information transmitting unit 120 associates information indicating the type of abnormality in the wiring relationship with the identifier of each communication channel, and transmits the information as one piece of management information to the control device 310 . Thus, wiring diagno...

Abstract

The wiring diagnosis device of the embodiment includes a counting unit, an acquisition unit, and an abnormality determination unit. The counting unit counts the number of battery modules connected to a plurality of first communication lines for each first communication line to which a plurality of battery modules are connected to form a communication channel. The acquisition unit acquires identification information for identifying the battery module connected to the second communication line from the battery modules connected to the plurality of second communication lines forming a communication channel together with the first communication line via the second communication line. The abnormality determination unit determines an abnormality in a wiring relationship of the first communication line or the second communication line based on the number of battery modules counted by the counting unit and the identification information acquired by the acquisition unit.

Description

technical field [0001] Embodiments of the present invention relate to a wiring diagnosis device, a battery system, and an electric power system. Background technique [0002] Conventionally, there is known a technique of managing a plurality of batteries and transmitting the state of the batteries to an external device. Conventionally, since a plurality of batteries are connected via one communication channel, the number of connectable batteries is limited due to attenuation of signals sent to the batteries. Therefore, in order to connect the battery beyond the upper limit, it is necessary to provide a plurality of communication channels. When a plurality of communication channels are provided, the wiring relationship of the communication lines forming the plurality of communication channels becomes complicated, and the wiring relationship tends to generate abnormalities. However, in the prior art, it is sometimes impossible to grasp the abnormality of the wiring relations...
