Description

一种车辆的蓄电池检测的方法以及电池检测设备
本申请要求于2020年7月10日提交中国专利局、申请号为202010663189.8、申请名称为“一种车辆的蓄电池检测的方法以及电池检测设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及汽车电子技术领域，特别是涉及一种车辆的蓄电池检测的方法以及电池检测设备。
背景技术
车辆的蓄电池检测的核心是要能够快速、准确的对蓄电池进行检测，从而评估蓄电池的健康状态，进而评估蓄电池是否需要更换。通常使用电池检测设备，例如，电池检测仪，对车辆的蓄电池进行检测。目前市面上使用的电池检测设备使用电导测量和负载测试两种方法。
但是，本发明的发明人在实现本发明实施例的过程中，发现：一般的电导测量采用100赫兹，1安左右负载电流进行测试，因为信号较弱，需要测量毫伏级的信号误差，容易受到环境干扰，导致测量不稳定，所以一般该方案要求电池需要处于稳定状态。然而，随着车辆的快速发展，高科技功能越来越多，导致车辆上的电器和电子单元越来越多，即使熄火时，一些智能化的设备仍然是在工作的，这样导致蓄电池持续处于对外供电状态，并且存在不同频率的噪声信号，此时使用电导测量则容易出现误判。
负载测试需要大电流放电，一般超过100安，并要求电池要处于满电状态，对于亏电状态的电池无法检测。
综上，传统的电导测量和负载测试很难对车辆的蓄电池进行准确测试，用户满意度不高。

实施例一
请参阅图2，图2是本发明实施例提供的一种车辆的蓄电池检测的方法的流程示意图，该方法包括以下步骤：
步骤S10：获取所述蓄电池的噪声强度，以及，所述蓄电池的电池信息。
车辆的蓄电池处于持续对外供电的情况下，蓄电池所在的环境存在不同程度的噪声，在所述噪声的噪声强度小时，可采用低负载电流进行测试，当所述噪声的噪声强度大时，采用低负载电流进行测试，则容易受到干扰从而导致对蓄电池的检测不准确。通过获取所述蓄电池的噪声强度以及进一步的根据所述噪声强度来调节所述电池检测设备的负载进行车辆的蓄电池检测，可提高对车辆的蓄电池检测的准确率。
在一些实施例中，所述蓄电池的噪声强度可根据所述蓄电池的电压跳动幅值和最大噪声电压幅值进行测量。具体的，请参阅图3，步骤S10包括：
步骤S101：获取所述蓄电池的电压跳动幅值以及最大噪声电压幅值。
在所电池检测设备连接于所述车辆时连续测试多个电压点，将电压点的最大值减去最小值即为电压跳动幅值。所述最大噪声电压幅值一般认为是电压跳动幅值中的最大值，所述最大噪声电压幅值为固定值，且所述最大噪声电压幅值为统计值，可以预先统计出来。
步骤S102：根据所述电压跳动幅值与所述最大噪声电压幅值，确定所述 蓄电池的噪声强度。
根据所述电压跳动幅值与所述最大噪声电压幅值，确定所述蓄电池的噪声强度的计算公式为：
蓄电池的噪声强度＝电压跳动幅值/最大噪声电压幅值
需要说明的是，在一些实施例中，蓄电池的噪声强度通过用1-100来表示，当计算获得的噪声强度大于100时，则可以直接将所述蓄电池的噪声强度定义为100，当计算获得的噪声强度小于1时，则可以直接将所述蓄电池的噪声强度定义为1。
对于所述电池信息，所述电池信息包括所述蓄电池的标称容量、所述蓄电池的当前容量、开路电压和温度。所述蓄电池的标称容量和所述蓄电池的当前容量用于选取所述电池检测方案。所述开路电压和/或温度用于检测所述蓄电池的健康状态。
