电力供应装置
技术领域
本发明涉及电力供应装置,特别是涉及从混合动力车辆的蓄电装置向外部设备供应电力的电力供应装置。
背景技术
另外,在以用汽油驱动的发动机和利用蓄电装置驱动的电动机作为驱动源的混合动力车辆中,用连接到发动机的发电机发电,对蓄电装置充入车辆的行驶所需的电力。
目前,即使在不能使用电力的情况下,为了有效利用如家电产品那样的外部设备,从安装于混合动力车辆的蓄电装置对外部设备供应电力的电力供应装置的外部供电部的需求提高。

发明内容
发明要解决的问题
但是,在以往的电力供应装置中,一般在安装有用汽油驱动的发动机的车中,仅安装12V电源,因此电量、电压不足,当要进行外部供电时,有需要用于使大电流流过的非常粗的电缆的不便。
因此,在安装有发动机的车中,不太适合于上述电力供应装置的安装。
基本上,安装有高电压电池、电缆且能发电的混合动力车辆、电动汽车适合于上述电力供应装置的安装。
但是,当进行外部供电时,除了目前的车辆所需的使用电量之外,也追加在外部供电中使用的电量,因此电池剩余量与不进行外部供电时相比降低得快,有可能行驶输出比通常更快地被限制,期望被改善。
并且,在对外部设备供应电力的情况下,除了车辆的行驶所需的电力之外,还需要用于对外部设备供应的电力,因此蓄电装置的剩余电量与不对外部设备供应电力的情况相比消耗电力变多,有限制行驶输出的频度变高的不便。
此外,上述的专利文献1~2所公开的技术提出了如下电力供应装置:驾驶员输入外部设备的种类、使用时间,基于外部设备的使用电力设定蓄电装置的发电电力。
本发明的目的是提供如下混合动力车辆的电力供应装置:在对外部设备供应电力的情况下,不需要驾驶员的输入操作就能抑制限制车辆的行驶输出的频度。
即,在本发明中,在具备电力供应装置的外部供电部的混合动力车辆中,在有外部供电的消耗电力的情况下,对发电请求电力追加外部供电的消耗电力量来进行发电。
此外,所谓“发电请求电力”是指驱动所需的电动机电力、在A/C、灯等中使用的辅机电力、对电池充放电的电力。
因此,在行驶时进行外部供电的情况下,能追加使用量来进行发电,实现电池剩余量的降低的抑制。(实现与未进行外部供电时相同的电池剩余量的减少方法。)
用于解决问题的方案
因此,为了消除上述不便,本发明是电力供应装置,具备:发电机;电动机;蓄电装置,其可由上述发电机产生的电力进行充电,并且可对上述电动机供应电力;以及外部供电部,其通过上述蓄电装置对车辆外部的外部设备供应电力,该电力供应装置在上述蓄电装置的蓄电剩余量降低时限制对上述电动机供应的电力,上述电力供应装置具备:外部供应电力算出部,其算出从上述外部供电部对上述外部设备供应的外部供应电力;以及发电请求电力算出部,其在上述外部设备被连接时,利用上述外部供应电力算出部算出上述外部供应电力,将上述外部供应电力和没有连接上述外部设备的情况下的发电电力相加,算出发电请求电力。
发明效果
根据本发明,在上述外部设备被连接的情况下,将车辆行驶所需的电力和外部供应电力相加,算出上述发电请求电力,因此能抑制由于连接外部设备而限制行驶输出的频度。
另外,在上述外部设备被连接时算出外部供电电力,因此能减少外部设备连接时的驾驶员的操作。

具体实施方式
以下基于附图详细说明本发明的实施例。
实施例
图1~图3是表示本发明的实施例的图。
在图2中,1是混合动力车辆。
该混合动力车辆1包括例如串联式混合动力车,具备发动机2、发电机(也称为“generator”。)3以及电动机(也称为“motor”。)4。
并且,上述混合动力车辆1在通常的控制状态下,利用汽油箱5内的汽油驱动上述发动机2,由上述发电机3发电,在通过逆变器6后,对包括驱动用电池的蓄电装置7充电。
此时,在上述混合动力车辆1行驶时,取出储存于上述蓄电装置7的电力,驱动上述电动机4,通过车轮轴8驱动车轮9。
另外,上述混合动力车辆1的蓄电装置7还具备外部供电装置10。
并且,对于从蓄电装置7供应到外部供电装置10的电流,能使用DCAC转换器11将直流电流转换为交流电流(100V)来使用。
而且,能用DCDC转换器12将来自上述蓄电装置7的电流转换成直流电流(12V)来使用。
上述混合动力车辆1具备电力供应装置13。
如图3所示,该电力供应装置13具备:上述发电机3;上述电动机4;上述蓄电装置7,其可由上述发电机3产生的电力进行充电,并且可对上述电动机4供应电力;以及通过上述蓄电装置7对车辆外部的外部设备供应电力的外部供电部14。
并且,上述电力供应装置13在上述蓄电装置7的蓄电剩余量降低时限制对上述电动机4供应的电力。
另外,上述电力供应装置13设为如下构成,具备:外部供应电力算出部15,其算出从上述外部供电部14对上述外部设备供应的外部供应电力;发电请求电力算出部16,其在上述外部设备被连接时利用上述外部供应电力算出部15算出上述外部供应电力,将上述外部供应电力和没有连接上述外部设备的情况下的发电电力相加,求出发电请求电力。
详细地说,在上述电力供应装置13中,如图3所示,上述外部供应电力算出部15连接于电压传感器17和电流传感器18,输入这些电压传感器17和电流传感器18的输出信号,算出对上述外部设备供应的外部供应电力。
并且,上述发电请求电力算出部16在利用上述外部供应电力算出部15算出外部供应电力后,将外部供应电力和没有外部设备的情况下的发电电力相加,算出发电请求电力。
由此,在上述外部设备被连接的情况下,利用上述发电请求电力算出部16将上述混合动力车辆1行驶所需的电力和外部供应电力相加,算出上述发电请求电力,因此能抑制由于连接外部设备而限制行驶输出的频度。
另外,在上述外部设备被连接时算出外部供电电力,因此能减少外部设备连接时的驾驶员的操作。
如果进一步说明的话,在具备上述外部供电部14的上述混合动力车辆1中,在有外部供电的消耗电力的情况下,对发电请求电力追加外部供电的消耗电力量来进行发电。
因此,在行驶时进行外部供电的情况下,能追加使用量来进行发电,因此能抑制上述蓄电装置7的电池剩余量的降低。
换言之,在该实施例的控制中采用与未进行外部供电时相同的上述蓄电装置7的电池剩余量的减少方法。
上述外部供电部14在上述混合动力车辆1的消耗电力大于上述发电请求电力的情况下,与对上述电动机4的供电限制相比,优先限制对上述外部设备的供电。
由此,在上述混合动力车辆1的消耗电力大于发电请求电力的情况下,与对上述电动机4的供电限制相比,优先限制外部设备的供电,因此能在混合动力车辆1的行驶中使用所产生的电力,能抑制限制行驶输出的频度。
接着,按照图1的上述混合动力车辆1的电力供应装置13的控制用流程图说明作用。
在该混合动力车辆1的电力供应装置13的控制用程序开始(101)时,转移到外部设备是否连接的判断(102)。
在该判断(102)中,判定有无外部供电电力的使用。
并且,在外部设备是否连接的判断(102)中,在该判断(102)为“是”的情况下,转移到算出外部供应电力的处理(103)。
在该处理(103)中,利用连接着上述电压传感器17和上述电流传感器18的上述外部供应电力算出部15算出对外部设备供应的外部供应电力。
在上述的外部设备是否连接的判断(102)为“否”的情况下,以及在算出外部供应电力的处理(103)后,转移到算出发电请求电力的处理(104)。
在该处理(104)中,在上述的外部设备是否连接的判断(102)为“否”的情况下,没有连接外部设备,因此利用上述发电请求电力算出部16仅使用没有连接外部设备的情况下的发电电力算出发电请求电力。
另外,在处理(104)中,在上述的算出外部供应电力的处理(103)后,外部设备被连接,因此利用上述发电请求电力算出部16将上述混合动力车辆1行驶所需的电力和算出的外部供应电力相加,算出发电请求电力。
在算出该发电请求电力的处理(104)后,转移到消耗电力是否为发电请求电力以上、即,
是否为消耗电力≥发电请求电力的判断(105)。
在该判断(105)中,比较实际的消耗电力和算出的发电请求电力。
并且,在消耗电力是否为发电请求电力以上、即,
是否为消耗电力≥发电请求电力的判断(105)中,在判断(105)为“否”的情况下,消耗电力小于发电请求电力,转移到后述的上述混合动力车辆1的电力供应装置13的控制用程序的结束(109)。
另外,在判断(105)为“是”的情况下,转移到对外部设备的供电停止的处理(106)。
在该处理(106)中,上述混合动力车辆1的消耗电力为算出的发电请求电力以上,因此利用上述外部供电部14,与对上述电动机4的供电限制相比,优先限制对外部设备的供电。
在对外部设备的供电停止的处理(106)后,转移到对外部设备的供电停止后的消耗电力是否为发电请求电力以上、即,
是否为消耗电力≥发电请求电力的判断(107)。
在该判断(107)中,在与对上述电动机4的供电限制相比,优先限制对外部设备的供电后,比较实际的消耗电力和算出的发电请求电力。
并且,在对外部设备的供电停止后的消耗电力是否为发电请求电力以上、即,
是否为消耗电力≥发电请求电力的判断(107)中,在判断(107)为“否”的情况下,对外部设备的供电停止后的消耗电力小于发电请求电力,因此转移到上述混合动力车辆1的电力供应装置13的控制用程序的结束(109)。
另外,在判断(107)为“是”的情况下,转移到进行对上述电动机4的供电限制的处理(108),然后转移到上述混合动力车辆1的电力供应装置13的控制用程序的结束(109)。
