<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 </ b> 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.

  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.

  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.

<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. . And in this form, the air blower 20 operates so that the air by the side of the positive electrode side air flow path 11 or the bypass air flow path 50 may be attracted | sucked. 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.

<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 </ b> 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.

  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.

  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.

  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.

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.

  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. That's fine. Thus, in the air battery system, the air battery can be stably operated by controlling the battery temperature even when the output of the battery changes.

  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.

Even when the required air amount changes, by controlling the external flow rate adjustment valve, air can be released to the external air flow path side, and the positive-side air flow rate and the air flow rate of the bypass air flow rate can be adjusted. Thereby, in the air battery system, even when the required air amount of the battery changes, the air battery can be stably operated by controlling the battery temperature. Moreover, there is an advantage that the external blower object and the blower can be shared.
