在本实施例中,通过采集车辆的蓄电池电量和动力电池电量并判断是否满足预设条件决定整车发电装置是否进行发电,可以使得整车发电装置根据蓄电池电量和动力电池电量的平衡智能化地进行发电,起到削峰填谷,稳定发电装置电流的作用。需要说明的是,由于结构限制,传统燃油车不具备整车发电装置的发电功能。

为了便于描述,在这里可以使用空间相对术语,如“在……之上”、“在……上方”、“在……上表面”、“上面的”等,用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位 置关系。应当理解的是,空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如,如果附图中的器件被倒置,则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而,示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位),并且对这里所使用的空间相对描述作出相应解释。
除上述以外,还需要说明的是在本说明书中所谈到的“一个实施例”、“另一个实施例”、“实施例”等,指的是结合该实施例描述的具体特征、结构或者特点包括在本申请概括性描述的至少一个实施例中。在说明书中多个地方出现同种表述不是一定指的是同一个实施例。进一步来说,结合任一实施例描述一个具体特征、结构或者特点时,所要主张的是结合其他实施例来实现这种特征、结构或者特点也落在本申请的范围内。
在上述实施例中,对各个实施例的描述都各有侧重,某个实施例中没有详述的部分,可以参见其他实施例的相关描述。
以上所述仅为本申请的优选实施例而已,并不用于限制本申请,对于本领域的技术人员来说,本申请可以有各种更改和变化。凡在本申请的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本申请的保护范围之内。
