＜第１の形態＞
まず、第１の形態に係る空気電池システムについて図面を参照しながら詳細に説明する。図１は、第１の形態に係る空気電池システムの概略を示す説明図である。図１に示すように、空気電池システム１は、空気電池１０と、送風機２０と、上流側空気流路３０と、下流側空気流路４０と、バイパス空気流路５０と、流量調整弁６０Ａ，６０Ｂと、電池温度センサ７０Ａと、演算処理制御装置８０を備えている。また、空気電池１０は、正極に活物質としての空気を導入する正極側空気流路１１を有している。更に、正極側空気流路１１の一端は上流側空気流路３０に接続されており、他端は下流側空気流路４０に接続されており、上流側空気流路３０には送風機２０が配設されている。また、上流側空気流路３０と下流側空気流路４０とはバイパス空気流路５０により接続されている。更に、流量調整弁６０Ａ，６０Ｂは、正極側空気流路１１の空気流量及びバイパス空気流路５０の空気流量を調整可能なものである。なお、流量調整弁６０Ａ，６０Ｂは、本形態においては、バイパス空気流路５０の上流側空気流路３０との接続部及び下流側空気流路４０との接続部に配設されている。また、電池温度センサ７０Ａは空気電池１０の温度を検知するものである。この電池温度センサとしては、例えば熱電対を利用した温度計など従来公知のものを適用することができる。更に、演算処理制御装置８０は、空気電池１０の作動温度基準データを格納するものである。この作動温度基準データは、例えば予備実験などにより当該空気電池の適切な作動温度を測定して決定することができる。なお、空気電池の仕様により作動温度基準データは異なるが、基準データの下限及び上限をそれぞれ例えば０℃及び１００℃のように設定してもよい。そして、空気電池システム１においては、演算処理制御装置８０が、電池温度センサ７０Ａから得られる電池温度データと演算処理制御装置８０自体が格納する作動温度基準データとを対比して得られる結果に基づいて、正極側空気流路１１の空気流量及びバイパス空気流路５０の空気流量を調整するために、送風機２０及び流量調整弁６０Ａ，６０Ｂの一方又は双方を制御する。なお、流量調整弁６０Ａ，６０Ｂはそれぞれ個別に制御することもできる。 <First form>
First, an air battery system according to a first embodiment will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram showing an outline of the air battery system according to the first embodiment. As shown in FIG. 1, the air battery system 1 includes an air battery 10, a blower 20, an upstream air passage 30, a downstream air passage 40, a bypass air passage 50, a flow rate adjustment valve 60A, 60B, a battery temperature sensor 70A, and an arithmetic processing control device 80 are provided. The air battery 10 also has a positive electrode side air passage 11 for introducing air as an active material into the positive electrode. Further, one end of the positive air flow channel 11 is connected to the upstream air flow channel 30, and the other end is connected to the downstream air flow channel 40, and the blower 20 is arranged in the upstream air flow channel 30. It is installed. The upstream air flow path 30 and the downstream air flow path 40 are connected by a bypass air flow path 50. Furthermore, the flow rate adjusting valves 60A and 60B are capable of adjusting the air flow rate of the positive-side air flow path 11 and the air flow rate of the bypass air flow path 50. In the present embodiment, the flow rate adjusting valves 60A and 60B are disposed at the connection portion of the bypass air passage 50 with the upstream air passage 30 and the connection portion with the downstream air passage 40. The battery temperature sensor 70 A detects the temperature of the air battery 10. As this battery temperature sensor, for example, a conventionally known one such as a thermometer using a thermocouple can be applied. Further, the arithmetic processing control device 80 stores the operating temperature reference data of the air battery 10. The operating temperature reference data can be determined by measuring an appropriate operating temperature of the air battery, for example, by a preliminary experiment. Although the operating temperature reference data varies depending on the specifications of the air battery, the lower limit and the upper limit of the reference data may be set to 0 ° C. and 100 ° C., for example. In the air battery system 1, the arithmetic processing control device 80 is based on the result obtained by comparing the battery temperature data obtained from the battery temperature sensor 70A with the operating temperature reference data stored in the arithmetic processing control device 80 itself. In order to adjust the air flow rate of the positive-side air flow path 11 and the air flow rate of the bypass air flow path 50, one or both of the blower 20 and the flow rate adjustment valves 60A and 60B are controlled. The flow rate adjusting valves 60A and 60B can be individually controlled.

例えば空気電池の温度が作動温度基準データの下限以下の場合には、例えば供給される空気流量を減少するように送風機を制御すると共に、正極側空気流路の空気流量の割合を増加させ、更にバイパス空気流路の空気流量の割合を減少させるように流量調整弁を制御すればよい。また、例えば空気電池の温度が作動温度基準データの上限以上の場合には、例えば供給される空気流量を増加するように送風機を制御すると共に、正極側空気流路の空気流量の割合を減少させ、更にバイパス空気流路の空気流量の割合を増加させるように流量調整弁を制御すればよい。これにより、空気電池システムにおいて、空気電池の温度が過度な高温状態や低温状態の場合であっても電池温度を制御して空気電池を安定作動させることができる。 For example, when the temperature of the air battery is less than or equal to the lower limit of the operating temperature reference data, for example, the blower is controlled so as to decrease the supplied air flow rate, and the ratio of the air flow rate in the positive air flow path is increased. What is necessary is just to control a flow regulating valve so that the ratio of the air flow rate of a bypass air flow path may be decreased. Further, for example, when the temperature of the air battery is equal to or higher than the upper limit of the operating temperature reference data, for example, the blower is controlled so as to increase the supplied air flow rate and the ratio of the air flow rate in the positive air flow path is decreased. Furthermore, the flow rate adjustment valve may be controlled so as to increase the ratio of the air flow rate of the bypass air flow path. Thereby, in the air battery system, even when the temperature of the air battery is excessively high or low, the battery temperature can be controlled to stably operate the air battery.

なお、図示しないが、本発明においては、空気電池の下流側には必ずしも流量調整弁を配設する必要はない。また、図示しないが、本発明においては、空気電池の上流側の流量調整弁は、上流側空気流路とバイパス空気流路との接続部より下流側の上流側空気流路と、バイパス空気流路の２カ所に配設してもよい。 Although not shown, in the present invention, it is not always necessary to provide a flow rate adjustment valve on the downstream side of the air battery. Although not shown, in the present invention, the upstream side flow rate regulating valve of the air battery includes an upstream air flow path and a bypass air flow downstream from the connection portion between the upstream air flow path and the bypass air flow path. You may arrange | position in two places of a path | route.

＜第２の形態＞
次に、第２の形態に係る空気電池システムについて図面を参照しながら詳細に説明する。なお、上記の形態において説明したものと同等のものについては、それらと同一の符号を付して説明を省略する。また、図示せずに説明した構成例も、本形態に適用可能であれば、そのまま又は適宜変形させて適用してもよく、その説明は省略する。図２は、第２の形態に係る空気電池システムの概略を示す説明図である。図２に示すように、注液型電池システム１’は、下流側空気流路４０に送風機２０が配設されている構成が、上述した第１の形態に係る空気電池システムと相違している。そして、本形態においては、正極側空気流路１１やバイパス空気流路５０側の空気を吸引するように送風機２０が作動する。このような構成であっても、上述した空気電池システムと同様に、空気電池の温度が過度な高温状態や低温状態の場合であっても電池温度を制御して空気電池を安定作動させることができる。 <Second form>
Next, an air battery system according to a second embodiment will be described in detail with reference to the drawings. In addition, about the thing equivalent to what was demonstrated in said form, the code | symbol same as them is attached | subjected and description is abbreviate | omitted. In addition, a configuration example described without being illustrated may be applied as it is or appropriately modified as long as it is applicable to the present embodiment, and the description thereof is omitted. FIG. 2 is an explanatory diagram showing an outline of the air battery system according to the second embodiment. As shown in FIG. 2, the liquid injection battery system 1 ′ is different from the air battery system according to the first embodiment described above in that the blower 20 is disposed in the downstream air flow path 40. . In this embodiment, the blower 20 operates so as to suck the air on the positive electrode side air flow path 11 and the bypass air flow path 50 side. Even in such a configuration, similarly to the above-described air battery system, the air battery can be stably operated by controlling the battery temperature even when the temperature of the air battery is excessively high or low. it can.

＜第３の形態＞
次に、第３の形態に係る空気電池システムについて図面を参照しながら詳細に説明する。なお、上記の形態において説明したものと同等のものについては、それらと同一の符号を付して説明を省略する。また、図示せずに説明した構成例も、本形態に適用可能であれば、そのまま又は適宜変形させて適用してもよく、その説明は省略する。図３は、第３の形態に係る空気電池システムの概略を示す説明図である。図３に示すように、注液型電池システム１Ａは、バイパス空気流路５０が空気電池１０と接続しており、その接続部に熱交換器５１を有している構成が、上述した第１の形態に係る空気電池システムと相違している。そして、注液型電池システム１Ａにおいては、演算処理制御装置８０が、電池温度センサ７０Ａから得られる電池温度データと演算処理制御装置８０自体が格納する作動温度基準データとを対比して得られる結果に基づいて、正極側空気流路１１の空気流量及びバイパス空気流路５０の空気流量を調整するために、送風機２０及び流量調整弁６０Ａ，６０Ｂの一方又は双方を制御する。 <Third embodiment>
Next, an air battery system according to a third embodiment will be described in detail with reference to the drawings. In addition, about the thing equivalent to what was demonstrated in said form, the code | symbol same as them is attached | subjected and description is abbreviate | omitted. In addition, a configuration example described without being illustrated may be applied as it is or appropriately modified as long as it is applicable to the present embodiment, and the description thereof is omitted. FIG. 3 is an explanatory diagram showing an outline of the air battery system according to the third embodiment. As shown in FIG. 3, the liquid injection type battery system 1 A has a configuration in which the bypass air flow path 50 is connected to the air battery 10, and a heat exchanger 51 is provided at the connection portion. This is different from the air battery system according to the embodiment. In the liquid injection type battery system 1A, a result obtained by the arithmetic processing control device 80 comparing the battery temperature data obtained from the battery temperature sensor 70A with the operating temperature reference data stored in the arithmetic processing control device 80 itself. Based on the above, in order to adjust the air flow rate of the positive-side air flow path 11 and the air flow rate of the bypass air flow path 50, one or both of the blower 20 and the flow rate adjustment valves 60A and 60B are controlled.

本形態においては、バイパス空気流路の空気電池との接続部に設けられた熱交換器が空気電池と熱交換することができるため、例えば空気電池の温度が作動温度基準データの上限以上の場合には、例えば供給される空気流量を増加するように送風機を制御すると共に、正極側空気流路の空気流量の割合を減少させ、更にバイパス空気流路の空気流量の割合を増加させるように流量調整弁を制御したときに、空気電池からの放熱を促進することができる。そのため、より早急に電池温度を適切な範囲に制御することができ、空気電池を安定作動させることができる。これは、空気電池の正極側空気流路に活物質を含む空気を流すことによって冷却する場合と比較して、正極側空気流路への活物質を含む空気の供給量を減少させることによって空気電池の更なる加熱を抑制し、バイパス空気流路に空気を流すことによって空気電池の放熱を促進することができるためである。 In this embodiment, since the heat exchanger provided in the connection portion of the bypass air passage with the air battery can exchange heat with the air battery, for example, when the temperature of the air battery is equal to or higher than the upper limit of the operating temperature reference data For example, the air flow rate is controlled so as to increase the flow rate of air supplied, while controlling the blower so as to decrease the proportion of the air flow rate in the positive-side air passage and further increase the proportion of the air flow rate in the bypass air passage. When the regulating valve is controlled, heat dissipation from the air battery can be promoted. Therefore, the battery temperature can be controlled to an appropriate range more quickly, and the air battery can be stably operated. This is because air is reduced by reducing the supply amount of air containing the active material to the positive electrode side air flow path as compared with the case of cooling by flowing air containing the active material to the positive air flow path of the air battery. This is because further heating of the battery is suppressed, and heat radiation of the air battery can be promoted by flowing air through the bypass air flow path.

なお、本形態においても、空気電池の温度が過度な高温状態や低温状態の場合であっても電池温度を制御して空気電池を安定作動させるために、上述した制御を実行することができる。 In this embodiment as well, the above-described control can be performed in order to control the battery temperature and stably operate the air battery even when the temperature of the air battery is excessively high or low.

また、図示しないが、バイパス空気流路と空気電池との接続部に設けられる熱交換器は空気電池が有するものであってもよい。 Moreover, although not shown in figure, the air battery may have the heat exchanger provided in the connection part of a bypass air flow path and an air battery.

＜第４の形態＞
次に、第４の形態に係る空気電池システムについて図面を参照しながら詳細に説明する。なお、上記の形態において説明したものと同等のものについては、それらと同一の符号を付して説明を省略する。また、図示せずに説明した構成例も、本形態に適用可能であれば、そのまま又は適宜変形させて適用してもよく、その説明は省略する。図４は、第４の形態に係る空気電池システムの概略を示す説明図である。図４に示すように、空気電池システム１Ｂは、空気電池１０の出力を検知する電池出力センサ７０Ｂを備え、演算処理制御装置８０が、空気電池１０の電池出力変化データと空気流量データとの関係を示す出力変化−流量マップデータ、及び空気電池１０の放電容量基準データの少なくとも一方を格納している構成が、上述した第３の形態に係る空気電池システムと相違している。ここで、出力変化−流量マップデータや放電容量基準データは、例えば予備実験などにより当該空気電池の適切な出力変化と流量との関係や放電容量を測定して決定することができる。なお、空気電池の仕様によりこれら出力変化−流量マップデータや放電容量基準データは異なるので、空気電池の仕様ごとのデータを格納しておくこともできる。そして、空気電池システム１Ｂにおいては、演算処理制御装置８０が、電池出力センサ７０Ｂから得られる電池出力データから演算される電池出力変化データと演算処理制御装置８０自体が格納する出力変化−流量マップデータとを対比して得られる結果及び電池出力センサ７０Ｂから得られる電池出力データから演算される放電容量データと演算処理制御装置８０自体が格納する放電容量基準データとを対比して得られる結果の一方又は双方に基づいて、正極側空気流路１１の空気流量及びバイパス空気流路５０の空気流量を調整するために、送風機２０及び流量調整弁６０Ａ，６０Ｂの一方又は双方を制御する。 <4th form>
Next, an air battery system according to a fourth embodiment will be described in detail with reference to the drawings. In addition, about the thing equivalent to what was demonstrated in said form, the code | symbol same as them is attached | subjected and description is abbreviate | omitted. In addition, a configuration example described without being illustrated may be applied as it is or appropriately modified as long as it is applicable to the present embodiment, and the description thereof is omitted. FIG. 4 is an explanatory diagram showing an outline of the air battery system according to the fourth embodiment. As shown in FIG. 4, the air battery system 1 B includes a battery output sensor 70 B that detects the output of the air battery 10, and the arithmetic processing control device 80 has a relationship between the battery output change data of the air battery 10 and the air flow rate data. Is different from the air battery system according to the third embodiment described above in that at least one of the output change-flow rate map data and the discharge capacity reference data of the air battery 10 is stored. Here, the output change-flow rate map data and the discharge capacity reference data can be determined by measuring the relationship between the appropriate output change of the air battery and the flow rate and the discharge capacity by, for example, a preliminary experiment. Since the output change-flow rate map data and the discharge capacity reference data differ depending on the specifications of the air battery, it is possible to store data for each air battery specification. In the air battery system 1B, the calculation processing control device 80 calculates the battery output change data calculated from the battery output data obtained from the battery output sensor 70B and the output change-flow rate map data stored in the calculation processing control device 80 itself. One of the result obtained by comparing the discharge capacity data calculated from the battery output data obtained from the battery output sensor 70B and the discharge capacity reference data stored in the arithmetic processing control device 80 itself. Or in order to adjust the air flow rate of the positive electrode side air flow path 11 and the air flow rate of the bypass air flow path 50 based on both, one or both of the blower 20 and the flow rate adjustment valves 60A and 60B are controlled.

本形態において、例えば空気電池の出力を増加させる場合には、例えば正極側空気流路の空気流量の割合を、供給される空気流量を増加するように送風機を制御するか、又はバイパス空気流量を減少するように流量調整弁を制御すればよい。また、本形態において、例えば空気電池の出力を減少させる場合には、例えば供給される空気流量を減少するように送風機を制御するか、又はバイパス空気流量を増加するように流量調整弁を制御すればよい。これにより、空気電池システムにおいて、電池の出力が変化する場合であっても電池温度を制御して空気電池を安定作動させることができる。 In this embodiment, for example, when the output of the air battery is increased, for example, the air flow rate of the positive side air flow path is controlled by controlling the blower so as to increase the supplied air flow rate, or the bypass air flow rate is increased. What is necessary is just to control a flow regulating valve so that it may decrease. Further, in this embodiment, for example, when the output of the air battery is decreased, for example, the blower is controlled so as to decrease the supplied air flow rate, or the flow rate adjusting valve is controlled so as to increase the bypass air flow rate.
