- the BMU 51 receives the ID number issued by the first battery pack 500, the address assignment process ends.
- this embodiment has the effects as described above, it also has the following problems.
- the amount of data at the time of battery data transmission is larger than the data at the time of battery data request command transmission, and the battery pack 500 in addition to its own data at the time of battery data transmission has all the battery packs 500 subsequent to itself. Need to send data from. Therefore, the LED lighting time for transmission varies between the battery packs 500, and the capacity balance between the battery packs 500 is lost.
- the imbalance in capacity between battery packs there is a fully charged battery pack when a fully charged battery pack and an empty battery pack are mixed in a series of battery packs connected in series. Therefore, when charged, it cannot be charged because it is overcharged, and since there is an empty battery pack, it is overdischarged when discharged, so it cannot be discharged. Thus, neither discharging nor charging is possible.
- the battery pack 500 needs to turn on an LED in order to transfer data that is not addressed to itself, resulting in a problem that power consumption increases.
- each of the N optical transmission modules Tx included in the BMU 51 and each of the optical reception modules Rx of the N battery packs 500 are connected one-to-one by an optical fiber. Further, each of the optical transmission modules Tx of the N battery packs 500 and each of the N optical reception modules Rx included in the BMU 51 are connected one-to-one by an optical fiber.
- battery data request commands are sequentially transmitted from the optical transmission module Tx of the BMU 51 to each battery pack 500, and when the battery data request command is received, the battery pack 500 receives the optical transmission module Tx. Transmits battery data to the BMU 51 (that is, the BMU 51 sequentially receives battery data from each battery pack 500).
- the battery data request command may be transmitted simultaneously from the BMU 51 to all the battery packs 500, and the BMU 51 may receive the battery data from all the battery packs 500 in parallel.
- each battery pack 500 can directly communicate with the BMU 51, it is possible to suppress variations in the LED lighting time between the battery packs 500, and to prevent the capacity balance between the battery packs 500 from being lost.
- the battery pack 500 does not need to transfer data that is not addressed to itself, so that power consumption can be suppressed.
- this configuration there is a problem that the number of transmission / reception ports and wirings on the BMU 51 side according to the number of battery packs 500 connected in series is increased.
- the battery data from which battery pack 500 can be uniquely identified by the connection port is uniquely identified by the connection port.
- the optical transmission module Tx of the first battery pack 500 is connected to the optical reception module Rx of the BMU 51 to which the second battery pack 500 should be connected.
- the battery data is identified as the battery data from the first battery pack 500, but is actually the battery data of the second battery pack 500 and the battery data from the second battery pack 500.
- an identification error that the battery data of the first battery pack 500 is actually generated occurs.
- the address assignment processing may be performed so that the battery pack 500 can be correctly identified.
- the address assignment process is performed as follows at the start of communication.
- Step 1 the BMU 51 issues an ID number (for example, “# 1”) to the battery pack 500 from the first transmission port (optical transmission module Tx) (for example, for the Nth battery pack 500). Issue an ID number).
- ID number for example, “# 1”
- Tx optical transmission module
- Step 2 Upon receiving the ID number, the battery pack 500 sets the ID number to its own ID number and responds to the BMU 51.
- Step 3 The BMU 51 issues the next ID number to the battery pack 500 from the next transmission port.
- the processing is completed. If the address assignment processing is performed in this way, the battery pack 500 transmits its own ID number to the BMU 51 when the battery data is transmitted, so that the BMU 51 can determine which battery pack 500 the battery data is from.
- the optical transmission modules Tx and the N optical reception modules Rx of the BMU 51 can be correctly identified without depending on the one-to-one wiring. However, if there is a one-to-one wiring mistake between each of the N optical transmission modules Tx of the BMU 51 and each of the optical reception modules Rx of the N battery packs 500, even if the address assignment process is performed, Misidentification occurs.
- FIG. 7 the configuration of the third embodiment of the communication system is shown in FIG.
- the BMU 51 and each battery pack 500 are daisy chain-connected by optical fiber for communication of battery data request, and N pieces of light transmission modules Tx and BMU 51 of each battery pack 500 are used for communication of battery data.
- the optical receiving modules Rx are connected one-to-one with an optical fiber.
- the BMU 51 transmits a battery data request command by designating an address for broadcast from its own optical transmission module Tx.
- the battery pack 500 that has received the battery data request command determines that it is addressed to itself from the broadcast address, transmits the battery data from its own optical transmission module Tx to the BMU 51, and supplies the battery to the next adjacent battery pack 500. Transfer the data request command.
- the N-th to second battery packs 500 sequentially transmit the battery data to the BMU 51, and the first battery pack 500 to which the battery data request command is transferred transmits the battery data to its own optical transmission module. While transmitting from Tx to BMU51, a battery data request command is transferred to BMU51.
- the BMU 51 that has received the battery data request command can determine whether the data is garbled or the optical line is disconnected by confirming the battery data request command. Note that an optical line for transferring a battery data request command from the first battery pack 500 to the BMU 51 is not essential (a connection form without such an optical line is also included in the daisy chain connection).
- an increase in communication ports in the BMU 51 can be suppressed as much as possible by combining daisy chain connection and one-to-one connection. Further, by broadcasting the battery data request command and transmitting the battery data by the one-to-one connection, it is possible to suppress the variation in the LED lighting time between the battery packs 500 and to suppress the balance of the capacity balance between the battery packs 500. It is also possible to reduce power consumption due to lighting.
- the battery data from which battery pack 500 can be uniquely identified by the connection port but the battery pack 500 can be correctly identified even if there is a wiring mistake as described in the second embodiment.
- the address assignment process as described below may be performed so that can be identified.
- the address assignment process is performed as described below at the start of communication (see FIG. 8, x in FIG. 8 indicates disable).
- Step 1 First, the BMU 51 broadcasts an address setting command to each battery pack 500.
- Step 2 Each battery pack 500 disables its own optical transmission module Tx connected in a daisy chain.
- Step 3 The BMU 51 issues an initial ID number (for example, “# 1”).
- Step 4 When the own light transmission module Tx is disabled, the battery pack 500 sets the received ID number to its own ID number, responds to the BMU 51 via the optical line for battery data transmission, The optical transmission module Tx is enabled. Then, the battery pack 500 issues an ID number obtained by adding 1 to its own ID number to the next adjacent battery pack 500.
- Step 5 When the first battery pack 500 has its own optical transmission module Tx disabled, the first battery pack 500 sets the received ID number to its own ID number, and transmits it to the BMU 51 via an optical line for battery data transmission. To enable the optical transmission module Tx.
- the address assignment process ends.
- the battery pack 500 transmits its own ID number to the BMU 51 when the battery data is transmitted, so that the BMU 51 can determine which battery pack 500 the battery data is from.
- the optical transmission modules Tx and the N optical reception modules Rx of the BMU 51 can be correctly identified without depending on the one-to-one wiring.
