[0026] [1. Configuration]

[0027] refer to figure 1 and figure 2 The configuration of the communication system 1 according to the present embodiment is described.

[0028] The communication system 1 is installed on a vehicle V1. The communication system 1 includes a management device 2 and battery module groups 3 . The communication system 1 may include a vehicle information unit 6 . The vehicle information unit 6 includes a plurality of in-vehicle sensors and devices that detect the state of the vehicle V1. More specifically, a wheel speed sensor, an acceleration sensor, a yaw rate sensor, etc. may be included.

[0029] Each of the individual battery modules (3-1 to 3-10) is similarly configured. A battery module 3 - 1 includes a terminal 4 and at least one battery unit 5 . That is, the communication system 1 includes a plurality of terminal devices 4 . The management device 2 performs wireless communication with each terminal device 4 . Each terminal device 4 acqu...

Deformed example 1

[0152] exist Figure 10 , the wireless communication unit 22 of Modification 1 (hereinafter referred to as wireless communication unit 22B) can be configured as shown. exist Figure 10 In the wireless communication unit 22B of Modification 1 shown in Figure 4 The first filter 223 , the second filter 224 , and the switch 225 included in the wireless communication unit 22A shown in , may be replaced by a duplexer 226 .

[0153] The duplexer 226 is a three-terminal filter located at the entrance from the antenna 21 (ie, at the exit to the antenna 21 ) and separates two frequency bands used in the communication system 1 . The duplexer 226 includes terminals 601 to 603 . The terminal 603 is connected to the antenna 21 . Terminal 602 is connected to transceiver switch 401 in first transceiver 221 . Terminal 603 is connected to transceiver switch 401 in second transceiver 222 .

[0154]In Modification 1, when the switching unit 65 switches the wireless communication unit 22B i...

Deformed example 2

[0157] exist Figure 11 , the wireless communication unit 22 (hereinafter referred to as wireless communication unit 22C) in Modification 2 may be configured as shown. Figure 11 The wireless communication unit 22C of Modification 2 shown in the Figure 4 The filter 227 between the switch 225 and the antenna 21 in the wireless communication unit 22A shown in . Filter 227 has two terminals. One of the two terminals of the filter 227 is connected to the antenna 21 , and the other terminal is connected to the switch 225 . In this embodiment, the filter 227 may be a BPF that passes the first frequency band and the second frequency band.

[0158] With this change, one of the three terminals of the switch 225 in the wireless communication unit 22C is connected to the above-described filter 227 instead of the antenna 21 . In Modification 2, when switching the wireless communication unit 22C into the above-described four states, the switching unit 65 outputs a switching signal, as...

Abstract

A communication system includes at least one terminal device (4) for acquiring at least information about a battery; and at least one management device (2). The management device communicates with the terminal device. One of the management device and the terminal device includes a multi-band communication device (22) configured to perform communication using plural, different frequency bands. The other of the management device and the terminal device includes a specific communication device (42) configured to perform communication using at least one frequency band among the plural, different frequency bands.

Description

technical field [0001] The present disclosure relates to a communication system including: at least one terminal device that acquires information about a battery; and at least one management device that communicates with the terminal device. Background technique [0002] For example, Japanese Patent Laid-Open No. JP 2016-12954 discussed below proposes a battery system including an intermediate management device and a terminal management device provided in each battery. The terminal management device obtains information about the battery. [0003] In the conventional technology described in Patent Document 1, an intermediate management device and a terminal management device perform wireless communication using one specific frequency band. [0004] However, as a result of the applicant's detailed study, the applicant of the present application has found that it is difficult to restore a good communication state between the intermediate management device and the terminal mana...
