　図１に示すように、補助電源システム１は、例えば自動車に搭載されており、主電源２に異常（例えば電力の供給不能など）が発生した場合に、主電源２に代わって補助電源５から電気機器３に電力を供給する。これにより、電気機器３は、主電源２からの電力が供給不能になった場合でも、補助電源５からの電力供給によって動作を継続可能である。なお、本実施形態では、自動車に搭載される場合を例示するが、自動車以外の移動体（例えば飛行機、船舶又は電車）であってもよい。 As shown in FIG. 1, the auxiliary power supply system 1 is mounted on an automobile, for example, and when an abnormality (for example, power supply failure) occurs in the main power supply 2, the auxiliary power supply 5 is used instead of the main power supply 2.

As a result, the specifications of the auxiliary power supply 5 (for example, capacity or output voltage) can be easily changed according to the specifications required by the mounted vehicle by changing the number of the plurality of power storage devices 4. be. Further, a communication address is assigned to each of the plurality of power storage devices 4. Thereby, for example, the plurality of power storage devices 4 can be individually controlled by the control from the electric device 3. Further, after the plurality of power storage devices 4 are connected to the auxiliary power supply system 1, communication addresses are assigned to the plurality of power storage devices 4.

As a result, the situation where the inventory of the power storage device 4 is surplus or insufficient depending on the communication address is suppressed, and the inventory management of the power storage device 4 becomes easy.
　本実施形態では、電気機器３が複数の蓄電装置４のバックアップ対象相手である。また、複数の蓄電装置４は、同一のバックアップ対象相手（電気機器３）に電力を供給する場合を例示する。以下、補助電源システム１の構成及び動作について詳しく説明する。 In the present embodiment, the electric device 3 is the backup target partner of the plurality of power storage devices 4.

The electric device 3 is an example of a backup target partner of the auxiliary power source 5. The electric device 3 is not limited to the device, but also includes a system. The electric device 3 operates by the electric power supplied from the main power source 2 in the normal state of the main power source 2, and operates by the electric power supplied from the auxiliary power source 5 (that is, a plurality of power storage devices 4) in the abnormal state of the main power source 2.

The brake system is a system that controls a brake device of an automobile according to a driver's brake pedal operation and detection results of various sensors. The steering system is a system that controls the steering of an automobile according to the driver's steering wheel operation and the detection results of various sensors.
　図２に示すように、電気機器３は、電源回路３１と、複数（例えば３つ）の出力部３２と、通信部３３と、制御部３４と、判定部３５とを備える。 As shown in FIG. 2, the electric device 3 includes a power supply circuit 31, a plurality of (for example, three) output units 32, a communication unit 33, a control unit 34, and a determination unit 35.
　電源回路３１は、第１給電路６１と接続されており、第１給電路６１を介して供給される電力を電気機器３の各部（通信部３３、制御部３４及び判定部３５など）に供給する。 The power supply circuit 31 is connected to the first power supply path 61, and supplies the electric power supplied through the first power supply path 61 to each part (communication unit 33, control unit 34, determination unit 35, etc.) of the electric device 3. do.
　複数の出力部３２は、複数の蓄電装置４に個別に起動信号を出力する部分である。複数の出力部３２は、複数の蓄電装置４と１対１に対応しており、対応する蓄電装置４の後述の入力部４２と信号線７を介して接続されている。 The plurality of output units 32 are portions that individually output start signals to the plurality of power storage devices 4. The plurality of output units 32 have a one-to-one correspondence with the plurality of power storage devices 4, and are connected to the input units 42 described later of the corresponding power storage devices 4 via a signal line 7.
　通信部３３は、通信線８を介して複数の蓄電装置４がそれぞれ備えている通信部４３との間で通信を行う。通信部３３は、通信線８を介して複数の蓄電装置４の通信部４３と接続されている。通信部３３は、例えばバス型の通信方式を採用する通信部である。バス型の通信方式として、例えば車載ネットワーク（例えばＬＩＮ（Local Interconnect Network）を採用してもよい。バス型の通信では、通信相手の通信アドレスを指定することで、通信相手との間でユニキャスト通信が可能である。このため、通信部３３は、各蓄電装置４が自身が使用する通信アドレス（自身用通信アドレス）を設定した後に、各蓄電装置４の通信部４３との間でユニキャスト通信が可能になる。なお、ユニキャスト通信とは、１つの通信アドレスを指定して行う１対１の通信である。通信部３３が使用する通信アドレスは、通信部３３に予め設定されている。 The communication unit 33 communicates with the communication unit 43 provided by each of the plurality of power storage devices 4 via the communication line 8. The communication unit 33 is connected to the communication units 43 of the plurality of power storage devices 4 via the communication line 8. The communication unit 33 is, for example, a communication unit that employs a bus-type communication method. As a bus-type communication method, for example, an in-vehicle network (for example, LIN (Local Interconnect Network)) may be adopted. In bus-type communication, a unicast with the communication partner is specified by specifying the communication address of the communication partner. Communication is possible. Therefore, after each power storage device 4 sets the communication address (own communication address) used by each power storage device 4, the communication unit 33 unicasts with the communication unit 43 of each power storage device 4. Communication becomes possible. Unicast communication is one-to-one communication performed by designating one communication address. The communication address used by the communication unit 33 is preset in the communication unit 33. ..
　制御部３４は、複数の出力部３２及び通信部３３を制御する。より詳細には、制御部３４は、例えば補助電源システム１の起動時に、複数の出力部３２から複数の蓄電装置４に起動信号を順番に送信する。例えば、制御部３４は、蓄電装置４Ａ、蓄電装置４Ｂ、蓄電装置４Ｃ及び蓄電装置４Ｄの順番に起動信号を送信する。起動信号の送信により、各蓄電装置４を起動させると共に、後述のように、各蓄電装置４に対して、通信線８を用いた通信で自身が使用する通信アドレス（自身用通信アドレス）を設定させる。その際、各蓄電装置４に順番に起動信号を送信することで、各蓄電装置４の自身用通信アドレスが、各蓄電装置４の間で重複することを防止する。このように、本実施形態では、電気機器３（バックアップ対象相手）が起動信号を各蓄電装置４に送信する。 The control unit 34 controls a plurality of output units 32 and a communication unit 33. More specifically, the control unit 34 sequentially transmits start signals from the plurality of output units 32 to the plurality of power storage devices 4 when the auxiliary power supply system 1 is started, for example. For example, the control unit 34 transmits a start signal in the order of the power storage device 4A, the power storage device 4B, the power storage device 4C, and the power storage device 4D. By transmitting the activation signal, each power storage device 4 is activated, and as described later, a communication address (own communication address) used by itself for communication using the communication line 8 is set for each power storage device 4. Let me. At that time, by transmitting the activation signal to each power storage device 4 in order, it is possible to prevent the own communication address of each power storage device 4 from being duplicated among the power storage devices 4. As described above, in the present embodiment, the electric device 3 (the backup target partner) transmits the start signal to each power storage device 4.
　なお、上記の「各蓄電装置４に順番に起動信号を送信する」とは、各蓄電装置４への起動信号の送信タイミングが重ならないようにして（すなわち送信タイミングを一定時間ずつずらすようにして）、各蓄電装置４に起動信号を送信することである。 The above-mentioned "transmitting the start-up signal to each power storage device 4 in order" means that the transmission timing of the start-up signal to each power storage device 4 does not overlap (that is, the transmission timing is shifted by a certain time). ), A start signal is transmitted to each power storage device 4.
　本実施形態では、制御部３４は、補助電源システム１の起動毎に、複数の出力部３２から複数の蓄電装置４に起動信号を送信する。これにより、制御部３４は、補助電源システム１の起動毎に、各蓄電装置４に対して自身用通信アドレスを設定させる。なお、補助電源システム１の起動とは、本実施形態では、電気機器３の起動である。 In the present embodiment, the control unit 34 transmits a start signal from the plurality of output units 32 to the plurality of power storage devices 4 each time the auxiliary power supply system 1 is started. As a result, the control unit 34 causes each power storage device 4 to set its own communication address each time the auxiliary power supply system 1 is started. The activation of the auxiliary power supply system 1 is the activation of the electric device 3 in the present embodiment.
　制御部３４は、通信部３３から送信する制御指令によって、各蓄電装置４の出力電力を個別に制御する。例えば、制御部３４は、通信部３３から送信する制御指令によって、各蓄電装置４の出力電圧を個別に増加又は減少させる。 The control unit 34 individually controls the output power of each power storage device 4 by a control command transmitted from the communication unit 33. For example, the control unit 34 individually increases or decreases the output voltage of each power storage device 4 by a control command transmitted from the communication unit 33.
　判定部３５は、第１給電路６１に印加されている電圧に基づいて、主電源２が正常であるか否か（すなわち欠陥が有るか）を判定する。本実施形態では、一例として、判定部３５は、第１給電路６１に印加されている電圧が閾値以上である場合は、主電源２は正常（すなわち欠陥無し）と判定する。また、判定部３５は、第１給電路６１に印加されている電圧が閾値未満である場合は、主電源２は異常（すなわち欠陥有り）と判定する。 The determination unit 35 determines whether or not the main power supply 2 is normal (that is, whether or not there is a defect) based on the voltage applied to the first power supply path 61. In the present embodiment, as an example, the determination unit 35 determines that the main power supply 2 is normal (that is, no defect) when the voltage applied to the first power supply path 61 is equal to or greater than the threshold value. Further, when the voltage applied to the first power supply path 61 is less than the threshold value, the determination unit 35 determines that the main power supply 2 is abnormal (that is, has a defect).
　主電源２は正常であると判定部３５が判定した場合は、制御部３４は、通信部３３から送信する制御指令によって、各蓄電装置４に対し、各蓄電装置４から電気機器３への電力の供給を停止させる。また、主電源２は異常であると判定部３５が判定した場合は、制御部３４は、通信部３３から送信する制御指令によって、各蓄電装置４に対し、各蓄電装置４から電気機器３への電力の供給を開始させる。 When the determination unit 35 determines that the main power supply 2 is normal, the control unit 34 sends power from each power storage device 4 to the electric device 3 for each power storage device 4 by a control command transmitted from the communication unit 33. Stop the supply of. When the determination unit 35 determines that the main power supply 2 is abnormal, the control unit 34 sends a control command transmitted from the communication unit 33 to each power storage device 4 from each power storage device 4 to the electric device 3.

　なお、本実施形態では、電気機器３（より詳細には判定部３５）が、主電源２が正常であるか否かを判定するが、電気機器３に代わって、各蓄電装置４が、主電源２が正常であるか否かを判定してもよい。この場合、各蓄電装置４は、主電源２が異常であると判定した場合は、自動的に、各第４給電路６２ｂを介して各蓄電装置４から電気機器３に電力の供給を開始する。 In the present embodiment, the electric device 3 (more specifically, the determination unit 35) determines whether or not the main power supply 2 is normal, but instead of the electric device 3, each power storage device 4 is the main. It may be determined whether or not the power supply 2 is normal. In this case, when each power storage device 4 determines that the main power supply 2 is abnormal, each power storage device 4 automatically starts supplying electric power from each power storage device 4 to the electric device 3 via each fourth power supply path 62b. ..
　制御部３４は、電気機器３がブレーキシステムである場合は、運転者のブレーキペダル操作及び各種のセンサの検出結果に応じて、自動車のブレーキ装置を制御する。また、制御部３４は、電気機器３がステアリングシステムである場合は、運転者のハンドル操作及び各種のセンサの検出結果に応じて、自動車の操舵を制御する。 When the electric device 3 is a brake system, the control unit 34 controls the brake device of the automobile according to the driver's brake pedal operation and the detection results of various sensors.

In other words, the communication unit 33, the control unit 34, and the determination unit 35 are realized by a computer having a CPU and a memory, and the computer controls the communication unit 33 by executing a program stored in the memory. It functions as a unit 34 and a determination unit 35. Although the program is pre-recorded in the memory, it may be provided through a telecommunication line such as the Internet or recorded in a recording medium such as a memory card.
　（蓄電装置）
　図３に示すように、蓄電装置４は、主電源２の異常状態において電気機器３（バックアップ対象相手）に電力を供給する補助電源５の構成要素である。蓄電装置４は、主電源２の正常状態では第３給電路６２ａを介して主電源２から供給される電力を蓄電し、蓄電した電力を、通信線８を介して電気機器３から受信する制御指令に応じて、第４給電路６２ｂを介して電気機器３に供給する。本実施形態では、複数の蓄電装置４は、並列接続されている。 (Power storage device)
As shown in FIG. 3, the power storage device 4 is a component of an auxiliary power source 5 that supplies electric power to an electric device 3 (a backup target partner) in an abnormal state of the main power source 2. The power storage device 4 stores the electric power supplied from the main power source 2 via the third power supply path 62a in the normal state of the main power source 2, and receives the stored electric power from the electric device 3 via the communication line 8. According to the command, the electric device 3 is supplied to the electric device 3 via the fourth power supply path 62b. In this embodiment, the plurality of power storage devices 4 are connected in parallel.
　蓄電装置４は、キャパシタ４１と、入力部４２と、通信部４３と、制御部４４とを備えている。 The power storage device 4 includes a capacitor 41, an input unit 42, a communication unit 43, and a control unit 44.
　キャパシタ４１は、第３給電路６２ａを介して主電源２から供給される電力を蓄電する部品である。キャパシタ４１は、例えば、電気二重層キャパシタ又はエナジーポリマーキャパシタである。 The capacitor 41 is a component that stores electric power supplied from the main power source 2 via the third power supply path 62a. The capacitor 41 is, for example, an electric double layer capacitor or an energy polymer capacitor.
　入力部４２は、電気機器３からの起動信号を受信する部分であり、信号線７を介して電気機器３における対応する出力部３２に接続されている。 The input unit 42 is a part that receives a start signal from the electric device 3, and is connected to the corresponding output unit 32 in the electric device 3 via a signal line 7.
　通信部４３は、通信線８に接続されており、通信線８を介して他の蓄電装置４及び電気機器３との間で通信（例えばバス型の通信）を行う。複数の蓄電装置４の各々の通信部４３は、同一の通信相手（電気機器３）と通信を行う通信機能を実行する。 The communication unit 43 is connected to the communication line 8 and performs communication (for example, bus-type communication) with another power storage device 4 and the electric device 3 via the communication line 8. Each communication unit 43 of the plurality of power storage devices 4 executes a communication function of communicating with the same communication partner (electrical device 3).
　制御部４４は、入力部４２を介して電気機器３からの起動信号を受信すると、当該電気機器３を起動させると共に、通信線８を用いた通信で自身が使用する通信アドレス（自身用通信アドレス）を設定する。より詳細には、制御部４４は、通信線８を用いた通信において他者（すなわち他の蓄電装置４及び電気機器３）の通信アドレスの使用状況を監視し、通信線８を用いた通信で使用されている他者の通信アドレス（他者が既に使用している通信アドレス）を特定する。 When the control unit 44 receives the activation signal from the electric device 3 via the input unit 42, the control unit 44 activates the electric device 3 and the communication address (own communication address) used by itself in the communication using the communication line 8. ) Is set. More specifically, the control unit 44 monitors the usage status of the communication address of another person (that is, another power storage device 4 and the electric device 3) in the communication using the communication line 8, and in the communication using the communication line 8. Identify the communication address of another person being used (a communication address already used by another person).
　なお、上記の他者が自身用通信アドレスを既に設定している場合は、通信線８を用いた通信で上記の他者の自身用通信アドレスが使用されている。このため、制御部４４は、通信線８を用いた通信において他者の通信アドレスの使用状況を監視することで、他者が既に使用している自身用通信アドレスを特定可能である。 If the other person has already set his / her own communication address, the other person's own communication address is used in the communication using the communication line 8. Therefore, the control unit 44 can identify the own communication address already used by the other person by monitoring the usage status of the communication address of the other person in the communication using the communication line 8.
　そして、制御部４４は、予め用意された複数の通信アドレスのうち、他者が使用していない１つ以上の未使用通信アドレスの中から選択した１つの通信アドレスを、自身が使用する自身用通信アドレスに設定する。なお、上記の予め用意された複数の通信アドレスは、例えば、蓄電装置４（例えば制御部４４）に予め保存されている。 Then, the control unit 44 uses one communication address selected from one or more unused communication addresses that are not used by others from among the plurality of communication addresses prepared in advance. Set to the communication address. The plurality of communication addresses prepared in advance are stored in advance in, for example, the power storage device 4 (for example, the control unit 44).
　制御部４４は、自身用通信アドレスを設定すると、設定した自身用通信アドレスを、通信部４３からブロードキャストで、通信線８に接続された全ての装置（すなわち電気機器３及び他の蓄電装置４）に送信する。これにより、電気機器３は、自身用通信アドレスを、通信線８に接続された全ての装置に通知する。 When the control unit 44 sets its own communication address, the control unit 44 broadcasts the set own communication address from the communication unit 43 to all the devices (that is, the electric device 3 and the other power storage device 4) connected to the communication line 8. Send to. As a result, the electric device 3 notifies all the devices connected to the communication line 8 of its own communication address.
　制御部４４は、設定した自身用通信アドレスを保存する非一時的記憶部（例えばフラッシュメモリなど）を備えていない。このため、制御部４４は、蓄電装置４が起動停止すると、設定した自身用通信アドレスを消去する。制御部４４は、電気機器３から起動信号を受信する毎に、上述のように自身用通信アドレスを設定する。 The control unit 44 does not have a non-temporary storage unit (for example, a flash memory) for storing the set own communication address. Therefore, when the power storage device 4 starts and stops, the control unit 44 erases the set own communication address. Each time the control unit 44 receives a start signal from the electric device 3, the control unit 44 sets its own communication address as described above.
　制御部４４は、通信線８を介して電気機器３から受信する制御指令に応じて、第４給電路６２ｂを介しての電気機器３への電力供給の開始及び停止を行う。また、制御部４４は、通信線８を介して電気機器３から受信する制御指令に応じて、第４給電路６２ｂを介して電気機器３に出力する電圧の増加及び減少を行う。 The control unit 44 starts and stops the power supply to the electric device 3 via the fourth power supply path 62b in response to the control command received from the electric device 3 via the communication line 8. Further, the control unit 44 increases and decreases the voltage output to the electric device 3 via the fourth power supply path 62b in response to the control command received from the electric device 3 via the communication line 8.
　本実施形態では、通信部４３及び制御部４４は、例えば、ＣＰＵ及びメモリを主構成とするマイクロコンピュータ（プロセッサ）で構成されている。言い換えれば、通信部４３及び制御部４４は、ＣＰＵ及びメモリを有するコンピュータで実現されており、ＣＰＵがメモリに格納されているプログラムを実行することにより、コンピュータが通信部４３及び制御部４４として機能する。プログラムはメモリに予め記録されているが、インターネット等の電気通信回線を通じて、又はメモリカード等の記録媒体に記録されて、提供されてもよい。 In the present embodiment, the communication unit 43 and the control unit 44 are composed of, for example, a microcomputer (processor) whose main configuration is a CPU and a memory. In other words, the communication unit 43 and the control unit 44 are realized by a computer having a CPU and a memory, and the computer functions as the communication unit 43 and the control unit 44 by executing a program stored in the memory by the CPU. do. Although the program is pre-recorded in the memory, it may be provided through a telecommunication line such as the Internet or recorded in a recording medium such as a memory card.
　（動作）
　次に図４を参照して、補助電源システム１の動作を説明する。より詳細には、蓄電装置４が自身の通信アドレスを設定（選択）するときの動作を説明する。 (motion)
Next, the operation of the auxiliary power supply system 1 will be described with reference to FIG. More specifically, the operation when the power storage device 4 sets (selects) its own communication address will be described.
　複数の蓄電装置４（４Ａ～４Ｃ）が補助電源システム１に接続されている。この状態では、複数の蓄電装置４には、通信部４３による通信（すなわち通信線８を用いた通信）で使用する自身用通信アドレスは設定されていない。この状態で、自動車のＩＧ（イグニション）スイッチがオフからオンに切り替えられる（Ｓ１）。これにより、第１給電路６１を介しての主電源２から電気機器３への電力の供給が開始される。 A plurality of power storage devices 4 (4A to 4C) are connected to the auxiliary power supply system 1. In this state, the plurality of power storage devices 4 are not set with their own communication addresses used for communication by the communication unit 43 (that is, communication using the communication line 8). In this state, the IG (ignition) switch of the automobile is switched from off to on (S1). As a result, the supply of electric power from the main power source 2 to the electric device 3 via the first power supply path 61 is started.
　この電力供給の開始により電気機器３が起動する。そして、電気機器３（バックアップ対象相手）は、起動後、まず蓄電装置４Ａに対して、信号線７を介して起動信号を送信する（Ｓ２）。そして、蓄電装置４Ａは、起動信号を受信すると、起動して、自身用通信アドレスを設定する（Ｓ３～Ｓ５）。より詳細には、蓄電装置４Ａは、通信線８を用いた通信において他者の通信アドレスの使用状況を監視し、通信線８を用いた通信で使用されている他者の通信アドレスを特定する。そして、蓄電装置４Ａは、予め用意された複数（例えば３つ）の通信アドレスのうちの１つ以上の未使用通信アドレスの中から通信アドレスを１つ選択し、選択した通信アドレスを自身用通信アドレスとして設定する。そして、蓄電装置４Ａは、設定した自身用通信アドレスを、通信線８を介して蓄電装置４Ａ以外の他の装置（電気機器３及び他の蓄電装置４Ｂ，４Ｃ）にブロードキャストで通知する（Ｓ６）。なお、ブロードキャストとは、通信線８に接続された全ての装置に送信することである。そして、上記の他の装置は、上記の通知を受信することで、通知された通信アドレスが蓄電装置４Ａの自身用通信アドレスであることを認識する（Ｓ７）。 The start of this power supply activates the electric device 3. Then, the electric device 3 (the backup target partner) first transmits a start signal to the power storage device 4A via the signal line 7 after the start (S2). Then, when the power storage device 4A receives the start signal, it starts and sets its own communication address (S3 to S5). More specifically, the power storage device 4A monitors the usage status of the communication address of another person in the communication using the communication line 8 and identifies the communication address of the other person used in the communication using the communication line 8. .. Then, the power storage device 4A selects one communication address from one or more unused communication addresses among a plurality of (for example, three) communication addresses prepared in advance, and communicates the selected communication address for its own use. Set as an address. Then, the power storage device 4A broadcasts the set own communication address to other devices (electrical equipment 3 and other power storage devices 4B, 4C) other than the power storage device 4A via the communication line 8 (S6). .. The broadcast is to transmit to all the devices connected to the communication line 8. Then, by receiving the above notification, the above-mentioned other device recognizes that the notified communication address is the own communication address of the power storage device 4A (S7).
　そして、電気機器３は、蓄電装置４Ａからの上記の通知を受信すると、次に蓄電装置４Ｂに対して、信号線７を介して起動信号を送信する（Ｓ８）。そして、蓄電装置４Ｂは、起動信号を受信すると、蓄電装置４Ａの場合と同様に、起動して自身用通信アドレスを設定する（Ｓ９～Ｓ１１）。そして、蓄電装置４Ｂは、設定した自身用通信アドレスを、通信線８を介して蓄電装置４Ｂ以外の他の装置（すなわち電気機器３及び他の蓄電装置４Ａ，４Ｃ）に通知する（Ｓ１２）。そして、上記の他の装置は、上記の通知を受信することで、通知された通信アドレスが蓄電装置４Ｂの自身用通信アドレスであることを認識する（Ｓ１３）。 Then, when the electric device 3 receives the above notification from the power storage device 4A, the electric device 3 then transmits a start signal to the power storage device 4B via the signal line 7 (S8). Then, when the power storage device 4B receives the start signal, it starts up and sets its own communication address (S9 to S11), as in the case of the power storage device 4A. Then, the power storage device 4B notifies the set own communication address to other devices (that is, the electric device 3 and the other power storage devices 4A, 4C) other than the power storage device 4B via the communication line 8 (S12). Then, by receiving the above notification, the other device recognizes that the notified communication address is the own communication address of the power storage device 4B (S13).
　そして、電気機器３は、蓄電装置４Ｂからの上記の通知を受信すると、次に蓄電装置４Ｃに対して、信号線７を介して起動信号を送信する（Ｓ１４）。そして、蓄電装置４Ｃは、起動信号を受信すると、蓄電装置４Ａの場合と同様に、起動して自身用通信アドレスを設定する（Ｓ１５～Ｓ１７）。そして、蓄電装置４Ｃは、設定した自身用通信アドレスを、通信線８を介して蓄電装置４Ｃ以外の他の装置（電気機器３及び他の蓄電装置４Ａ，４Ｂ）に通知する（Ｓ１８）。そして、上記の他の装置は、上記の通知を受信することで、通知された通信アドレスが蓄電装置４Ｃの自身用通信アドレスであることを認識する（Ｓ１９）。そして、処理が終了する。 Then, when the electric device 3 receives the above notification from the power storage device 4B, the electric device 3 then transmits a start signal to the power storage device 4C via the signal line 7 (S14). Then, when the power storage device 4C receives the start signal, it starts up and sets its own communication address (S15 to S17), as in the case of the power storage device 4A. Then, the power storage device 4C notifies the set own communication address to other devices (electrical device 3 and other power storage devices 4A, 4B) other than the power storage device 4C via the communication line 8 (S18). Then, by receiving the above notification, the above-mentioned other device recognizes that the notified communication address is the own communication address of the power storage device 4C (S19). Then, the process ends.
　なお、この動作説明では、電気機器３は、一の蓄電装置４に起動信号を送信し、その蓄電装置４から自身用通信アドレスを知らせる通知を受信すると、次の蓄電装置４に起動信号を送信することで、起動信号を複数の蓄電装置４に順番に送信する。ただし、電気機器３は、上記の通知の受信に関係なく、起動信号を複数の蓄電装置４に一定時間間隔で順番に送信することで、起動信号を複数の蓄電装置４に順番に送信してもよい。 In this operation description, the electric device 3 transmits a start signal to one power storage device 4, and when it receives a notification notifying its own communication address from the power storage device 4, it transmits a start signal to the next power storage device 4. By doing so, the start-up signal is sequentially transmitted to the plurality of power storage devices 4. However, regardless of the reception of the above notification, the electric device 3 sequentially transmits the start signal to the plurality of power storage devices 4 at regular time intervals, thereby transmitting the start signal to the plurality of power storage devices 4 in order. May be good.
　（複数の蓄電装置４の識別が必要な状況）
　補助電源システム１では、複数の蓄電装置４は、通信アドレスによって識別可能である。このため、複数の蓄電装置４は、通信線８を用いた通信によって個別に制御可能である。以下、複数の蓄電装置４の個別制御が必要な状況を例示する。 (Situation where identification of a plurality of power storage devices 4 is required)
In the auxiliary power supply system 1, the plurality of power storage devices 4 can be identified by the communication address. Therefore, the plurality of power storage devices 4 can be individually controlled by communication using the communication line 8. Hereinafter, a situation in which individual control of a plurality of power storage devices 4 is required will be illustrated.
　（例１）
　複数の蓄電装置４の何れかが劣化して使用不可能になった場合、劣化した蓄電装置４のみを不使用にする必要がある。この場合は、電気機器３は、通信線８を介して各蓄電装置４から各蓄電装置４の出力電圧及び充電状態に関する情報を受信し、その受信結果に基づいて、各蓄電装置４が劣化しているか否かを判定する。そして、電気機器３は、複数の蓄電装置４のうち、劣化していない蓄電装置４のみ起動させ（すなわち使用し）、劣化している蓄電装置４を起動させない（すなわち使用しない）。 (Example 1)
When any of the plurality of power storage devices 4 deteriorates and becomes unusable, it is necessary to disable only the deteriorated power storage device 4. In this case, the electric device 3 receives information on the output voltage and the charging state of each power storage device 4 from each power storage device 4 via the communication line 8, and each power storage device 4 deteriorates based on the reception result. Determine if it is. Then, the electric device 3 activates (that is, uses) only the non-deteriorated power storage device 4 among the plurality of power storage devices 4, and does not activate (that is, does not use) the deteriorated power storage device 4.
　（例２）
　蓄電装置４の温度が低い場合は、蓄電装置４の充電能力が低下する。この場合は、各蓄電装置４の温度情報（例えば周囲温度の情報）を電気機器３に出力し、電気機器３は、通信線８を介して各蓄電装置４を個別に制御することで、温度の低い蓄電装置４の出力電圧を上昇させて、温度の低い蓄電装置４の充電能力の低下を防止する。なお、この例３では、蓄電装置４は、蓄電装置４の温度（例えば周囲温度）を計測するための温度センサ（例えばサーミスタ）を備えている。 (Example 2)
When the temperature of the power storage device 4 is low, the charging capacity of the power storage device 4 decreases. In this case, the temperature information (for example, ambient temperature information) of each power storage device 4 is output to the electric device 3, and the electric device 3 controls each power storage device 4 individually via the communication line 8 to obtain the temperature. The output voltage of the low temperature power storage device 4 is increased to prevent a decrease in the charging capacity of the low temperature power storage device 4. In this example 3, the power storage device 4 includes a temperature sensor (for example, a thermistor) for measuring the temperature (for example, ambient temperature) of the power storage device 4.
　（例３）
　電気機器３がブレーキシステムである場合において、ブレーキ力を高めるとき、複数の蓄電装置４の出力電圧にばらつきがある場合は、複数の蓄電装置４の出力電圧のばらつきを揃えつつ、複数の蓄電装置４の出力電圧を増大させる必要がある。この場合は、電気機器３は、通信線８を介して各蓄電装置４から出力電圧の情報を受信し、通信線８を介して各蓄電装置４を個別に制御することで、複数の蓄電装置４の出力電圧のばらつきを揃えつつ複数の蓄電装置４の出力電圧を増大させる。 (Example 3)
In the case where the electric device 3 is a braking system, when the braking force is increased, if the output voltages of the plurality of power storage devices 4 vary, the plurality of power storage devices may be arranged while the variations of the output voltages of the plurality of power storage devices 4 are aligned. It is necessary to increase the output voltage of 4. In this case, the electric device 3 receives the output voltage information from each power storage device 4 via the communication line 8 and individually controls each power storage device 4 via the communication line 8 to obtain a plurality of power storage devices. The output voltages of the plurality of power storage devices 4 are increased while making the variations of the output voltages of 4 uniform.
　以上の例のように、複数の蓄電装置４の個別制御は、一般には、自動車の走行状態（例えば車速）及び蓄電装置４の周囲環境（例えば周囲温度）に応じて、複数の蓄電装置４の出力電圧を個別に増減させるときに有効である。 As described above, the individual control of the plurality of power storage devices 4 is generally performed by the plurality of power storage devices 4 according to the traveling state of the automobile (for example, vehicle speed) and the ambient environment (for example, ambient temperature) of the power storage device 4. This is effective when increasing or decreasing the output voltage individually.
　（主要な効果）
　以上のように、本実施形態に係る補助電源システム１によれば、バックアップ対象相手（例えば電気機器３）に対して電力を供給するための複数の蓄電装置４を備える。複数の蓄電装置４はそれぞれ、同一の通信相手（例えば電気機器３）と通信を行う通信機能（通信部４３）を有する。複数の蓄電装置４はそれぞれ、通信相手と通信するために用意された複数の通信アドレスのうち、使用されていない１つ以上の未使用通信アドレスの中から選択した１つの通信アドレスを、自身が使用する自身用通信アドレスに設定する。 (Main effect)
As described above, according to the auxiliary power supply system 1 according to the present embodiment, a plurality of power storage devices 4 for supplying electric power to the backup target partner (for example, the electric device 3) are provided. Each of the plurality of power storage devices 4 has a communication function (communication unit 43) for communicating with the same communication partner (for example, an electric device 3). Each of the plurality of power storage devices 4 themselves selects one communication address selected from one or more unused communication addresses that are not used among the plurality of communication addresses prepared for communicating with the communication partner. Set to your own communication address to use.
　この構成によれば、複数の蓄電装置４を補助電源システム１に接続した後に、複数の蓄電装置４に通信アドレスを割り振ることができる。この結果、複数の蓄電装置４を通信アドレスで区別することなく製造及び管理が可能になる。 According to this configuration, after connecting a plurality of power storage devices 4 to the auxiliary power supply system 1, communication addresses can be assigned to the plurality of power storage devices 4. As a result, it becomes possible to manufacture and manage a plurality of power storage devices 4 without distinguishing them by communication addresses.
