Therefore, after that, by executing refresh charging, the period required for setting the average SOC from S2 to Sf (full charge) (period from time T2 to T3) is the period required for refresh charging in the comparative example (time T2). To the period T4).
- the refresh charge period is shortened compared to the comparative example, as in the case where the charge / discharge rate is relatively low.
- the precharge period (T2-T1) when the charge / discharge rate is relatively high is shorter than the precharge period (T2-T0) when the charge / discharge rate is relatively low. Therefore, since the period during which the average SOC is kept at a relatively high value (S2) can be shortened, it is possible to secure a large capacity capable of receiving the electric power generated by the fuel power generation in the battery 30. For this reason, fuel consumption can be improved.
- the charge control unit 20 of the first embodiment sets the first threshold time so that the pre-charging period is shortened when the charge / discharge rate is high, the charge / discharge rate is high.
- the period during which the SOC of battery 30 is relatively high can be shortened. Therefore, as compared with the configuration in which the precharge period is constant regardless of the charge / discharge rate, it is possible to secure a larger capacity capable of receiving the electric power generated by the fuel power generation in the battery 30 and improve the fuel efficiency.
- the precharge start timing and the refresh charge start timing are determined based on the elapsed time after the battery 30 is fully charged, the battery 30 is set at an appropriate timing according to the deterioration state of the battery 30. Can be fully charged.
- the period required for refresh charging can be shortened. For this reason, since the period during which the idle stop control is prohibited can be shortened with the execution of the refresh charge, the fuel consumption can be improved.
- FIG. 8 is an explanatory diagram showing a detailed configuration of the electronic control unit 10a in the second embodiment.
- FIG. 9 is a flowchart showing the procedure of the charging control process in the second embodiment.
- FIG. 10 is a flowchart illustrating a procedure of threshold adjustment processing according to the second embodiment.
- the electronic control unit 10a of the second embodiment includes a charge control unit 20a instead of the charge control unit 20, a detailed procedure of the charge control process, and a threshold value adjustment process instead of the threshold time adjustment process.
- the other configuration is the same as the electronic control unit 10 of the first embodiment.
- the start timing of the pre-charging and the refresh charging is determined based on the elapsed time after the battery 30 is fully charged.
- these triggers are determined based on the integrated value of the charge / discharge current of the battery.
- the charging control unit 20a of the second embodiment includes a threshold value setting unit 17a instead of the threshold time setting unit 17, and a threshold value instead of the charging period determination map mp1.
- the configuration of the first embodiment is different from that of the charge control unit 20 of the first embodiment in that the determination map mp2 is provided and the current integrated value calculation unit 21 is provided instead of the elapsed time measurement unit 19. It is the same as the charge control unit 20 of the form.
- Threshold value setting unit 17a executes threshold value adjustment processing described later.
- the current integrated value calculation unit 21 calculates a charge / discharge current integrated value. Details of the charge / discharge current integrated value and the threshold determination map mp2 will be described later.
- step S105a is executed instead of step S105
- step S110a is executed instead of step S110
- step S120a is executed instead of step S120
- step S135a is executed instead of step S135
- the other procedures are the same as the charge control process of the first embodiment.
- the current integrated value calculation unit 21 calculates the charge / discharge current integrated value (step S105a).
- the charge / discharge current integrated value means a total value of the absolute value of the discharge current integrated value and the absolute value of the charge current integrated value after the battery 30 is fully charged.
- Threshold value setting unit 17a determines whether the charge / discharge current integrated value calculated in step S105a is equal to or greater than the first threshold value (step S110a). When it is determined that the charge / discharge current integrated value is smaller than the first threshold value (step S110a: NO), the above-described step S105a is executed. When it is determined that the charge / discharge current integrated value is greater than or equal to the first threshold (step S110a: YES), the above-described step S115 (pre-charge) is executed.
- the first threshold value is determined by a threshold adjustment process described later.
- the refresh charge execution unit 24 acquires the charge / discharge current integrated value from the current integrated value calculation unit 21 and determines whether the charge / discharge current integrated value is equal to or greater than the second threshold value.
- the second threshold value is a fixed value set in advance by the user as a charge / discharge current integrated value from the end of the refresh charge to the start of the next refresh charge.
- the longer the elapsed time from the fully charged state the more chances of charging or discharging in the battery 30 increase, so the integrated charge / discharge current value increases. That is, the elapsed time from the fully charged state and the charge / discharge current integrated value are proportional to each other. Therefore, when a larger value is set as the second threshold value, refresh charging is performed with a longer time interval.
- step S120a: NO When the charge / discharge current integrated value is less than the second threshold value (step S120a: NO), step S115 described above is executed (continued), and the charge / discharge current integrated value is greater than or equal to the second threshold value. In this case, step S125 (refresh charging) and step S130 described above are executed.
- step S130 when it is determined that the battery 30 is fully charged (step S130: YES), the current integrated value calculation unit 21 resets the calculated charge / discharge current integrated value (step S135).
- FIG. 10 is a flowchart showing a procedure of threshold adjustment processing in the second embodiment.
- a threshold adjustment process is started when an ignition switch (not shown) is turned on, and such a process is repeatedly executed until the ignition switch is turned off.
- the threshold adjustment process is a process for adjusting the first threshold described above.
- the threshold value setting unit 17a acquires the charge / discharge current integrated value from the current integrated value calculating unit 21 (step S305), and determines whether the value is equal to or greater than a third threshold value (step S310).
- the third threshold value is a fixed value that is smaller than the second threshold value, and is set in advance by the user. As the third threshold value, for example, a value smaller than the second threshold value by 60000 As (ampere seconds) can be set.
- step S310: NO When it is determined that the charge / discharge current integrated value is less than the third threshold value (step S310: NO), the above-described step S305 is executed. On the other hand, when it determines with a charging / discharging electric current integrated value being more than a 3rd threshold value (step S310: YES), the charging / discharging rate calculation part 16 calculates a charging / discharging rate (step S315). This process is the same as step S215 shown in FIG.
- the threshold value setting unit 17a refers to the threshold value determination map mp2, and based on the charge / discharge rate calculated in step S315, for the second threshold value (charge / discharge current integrated value at the start of refresh charge), An offset value of the first threshold value (charge / discharge current integrated value at the start of pre-charging) is determined (step S320).
- FIG. 11 is an explanatory diagram schematically showing the setting contents of the threshold value determination map mp2 shown in FIG.
- the horizontal axis represents the charge / discharge rate
- the vertical axis represents the offset value (current integrated value) of the first threshold value with respect to the second threshold value.
- the charge / discharge rate is divided into five levels, similarly to the charging period determination map mp1 shown in FIG.
- the same offset value is set for each level. Specifically, 50000As is set as an offset value for level 1 where the charge / discharge rate is 0% or more and 20% or less.
- 40000 As for level 2 where the charge / discharge rate is greater than 20% and 40% or less, and 30000 As for level 3 where the charge / discharge rate is greater than 40% and 60% or less are charged / discharged.
- the offset value is set to 20000 As for level 4 where the rate is greater than 60% and 80% or less, and 10000 As for level 1 where the charge / discharge rate is greater than 80% and 100% or less. ing. Therefore, as shown in FIG. 11, a smaller offset value is set for a higher charge / discharge rate level.
- the charge / discharge rate becomes higher as the frequency of idling stop is lower and the current consumption of the auxiliary machine 70 is lower. Therefore, in the second embodiment, a smaller value is set as the offset value as the idling stop frequency is lower and the current consumption of the auxiliary device 70 is lower.
- the threshold value setting unit 17a is obtained by subtracting the offset value obtained in step S320 from the second threshold value.
- the set value is set as the first threshold value (step S325).
- the offset value is set to a smaller value as the charge / discharge rate is higher, a larger value is set as the first threshold value.
- the elapsed time and the charge / discharge current value integrated value are in a proportional relationship. Therefore, as the charge / discharge rate is higher, the battery 30 is fully charged, and after a longer period of time has elapsed, pre-charging (step S115) is started.
- the charge control unit 20a of the second embodiment described above has the same effect as the charge control unit 20 of the first embodiment.
- a larger value is set as the first threshold value, and a fixed value is set as the second threshold value.
- the precharge period can be shortened when the charge / discharge rate is higher.
- the precharge start timing and the refresh charge start timing are determined based on the charge / discharge current integrated value, the battery 30 can be fully charged at an appropriate timing according to the deterioration state of the battery 30.
- Modification 1 In each embodiment, the method of setting the target SOC (the upper limit value of the SOC range) to a high predetermined value regardless of the wheel speed has been adopted as a method of increasing the average SOC at the time of pre-charging and refresh charging.
- the present invention is not limited to this.
- a method of increasing the amount of charge per unit time by controlling the alternator 50 and increasing the voltage during charging may be employed.
- a method of prohibiting suppression of charging of the battery 30 when the current SOC exceeds the target SOC may be employed. That is, in general, any process that can increase the average SOC of the battery 30 can be employed as the precharge of the present invention.
- the SOC indicates a value obtained by dividing the amount of electricity remaining in the battery 30 by the amount of electricity stored when the battery 30 is fully charged (maximum storage capacity).
- the period during which the pre-charging is performed is sufficiently shorter than the period during which the pre-charging is not performed, and thus the maximum storage capacity is not greatly reduced during the period. Therefore, increasing the average SOC by precharging means increasing the average remaining capacity of the battery 30 by precharging. Therefore, any process that can increase the average remaining capacity of the battery 30 can be employed as the pre-charging of the present invention.
- the charging / discharging rate is divided into five levels, and the same charging period is set for each level.
- the present invention is not limited to this.

- the present invention is not limited to this. Is not to be done.
- the threshold value determination map mp2 a map in which the first threshold value is explicitly associated with the charge / discharge rate is used instead of the offset value.
- a threshold may be determined.
- the vehicle is an automobile, but the present invention can be applied to an arbitrary vehicle such as a motorcycle as well as an automobile. Furthermore, the present invention can be applied not only to vehicles but also to various moving bodies such as ships and robots. Further, the present invention can be applied to a power generation system that uses a battery and an engine as a stationary power source.

C1.変形例1:
各実施形態では、事前充電及びリフレッシュ充電の際に、平均SOCを上昇させる方法として、車輪速に関わらず目標SOC(SOC範囲の上限値)を高い所定値に設定する方法を採用していたが、本発明は、これに限定されない。例えば、オルタネータ50を制御して、充電時の電圧を上昇させることにより、単位時間当たりの充電量を上昇させる方法を採用してもよい。また、例えば、現在のSOCが目標SOCを上回った場合におけるバッテリ30への充電の抑制を禁止する方法を採用してもよい。すなわち、一般には、本発明の事前充電として、バッテリ30の平均SOCを増加可能な任意の処理を採用することができる。また、本実施形態では、SOCとは、バッテリ30に残存している電気量を、バッテリ30を満充電したときに蓄えられる電気量(最大蓄積容量)で除して得られる値を示している。ここで、事前充電が実行される期間は、事前充電が実行されていない期間に比べて十分に短いため、かかる期間において最大蓄積容量が大きく減少することはない。よって、事前充電により平均SOCを上昇させることは、事前充電によりバッテリ30の平均残存容量を上昇させることを意味する。したがって、本発明の事前充電として、バッテリ30の平均残存容量を増加可能な任意の処理を採用することができる。
第1実施形態において、充電期間決定マップmp1では、充放電率が5つのレベルに区分けされ、各レベル毎に同じ充電期間が設定されていたが、本発明は、これに限定されるものではない。例えば、レベルを省略し、充放電率の増加と共に受電期間が単調減少するように設定してもよい。同様に、第2実施形態のしきい値決定マップmp2においても、レベルを省略し、充放電率の増加と共にオフセット値が単調減少するように設定してもよい。
第2実施形態では、第1しきい値を、第2しきい値に対するオフセット値を決定し、かかるオフセット値を第1しきい値から差し引くことで決定していたが、本発明はこれに限定されるものではない。例えば、しきい値決定マップmp2として、オフセット値に代えて、第1しきい値を充放電率と明示的に対応付けたマップを用い、かかるマップを参照して充放電率に基づき第1しきい値を決定してもよい。
各実施形態では、車両は自動車であったが、自動車に限らず二輪車など、任意の車両に本発明を適用することができる。さらに、本発明は、車両のみならず、例えば、船舶やロボットなどの各種移動体に適用することもできる。また、バッテリ及びエンジンを定置型電源として用いる発電システム等にも適用することができる。すなわち、一般には、エンジンと、エンジンにより駆動される発電機と、発電機により生じた電力により充電されるバッテリとを有し、エンジンの停止状態においてエンジンの始動を禁止する停止制御が実行され得るシステムにおいて用いられ、バッテリの充電を制御する任意の装置に、本発明を適用することができる。なお、前述の「エンジンの停止状態」とは、エンジンが完全に停止した状態に限定されるものではなく、例えば、車両の移動速度が所定の速度(例えば、10km/h)以下となるようなエンジンの状態を含む広い意味を有する。
上記実施例において、ソフトウェアによって実現されていた構成の一部をハードウェアに置き換えるようにしてもよい。また、これとは逆に、ハードウェアによって実現されていた構成の一部をソフトウェアに置き換えるようにしてもよい。
