电池在多个行业领域都是关键技术,包括个人设备、交通、工业设备。要保证满足电池的质量和性能的需求,面临着若干挑战,只有具备检测细微症状的高超能力,才能预见未来的设备故障。
SPEA 一直为世界各大电池制造商供应测试设备,其设备能够结合准确的电气测试与非常精准的机械参数检验。
每一个生产出来的电池包和模块的性能、寿命和安全性都必须得到保证。这只有借助自动化、高吞吐量、灵活的测试设备才能做到。
SPEA 电池测试仪基于最新的 SPEA 飞针架构,可以测量、测试所有电池包 和模块的典型特性参数,其中包括电池线束焊接质量、电池内阻(包括交流电和直流电),开路电压,等等。
测试区域设计为可放置最大型的电池包和模块,包括模块的自动对齐功能和自动 Z 坐标变化补偿,以确保正确接触,避免虚假故障。
电池线束电阻的测量是使用高度精确的千分尺进行的,能够在几毫秒内测量几个微欧姆。
此外,开尔文探针可以使用受力控制的执行器(5-2,500 g 范围)接触电池,确保探测性能,而不会损坏或在接触表面留下痕迹。 该设备包括一个基于激光的精确测量仪,可准确测量电池包尺寸(长度、宽度和高度),识别模块组装过程中可能产生的翘曲。
经过测试的电池包和模块由重型输送机运输,输送机可以设置为直通或回传配置。
电池厚度和无变形是通过基于两个精确平行板的顶级千分尺验证的。 这两个板在保持绝对平行度的情况下向对方移动,大约为几微米。 此外,该模块在接触被测电池时具有力度感应的能力:在厚度测量的过程中,将会施加 50 至 2500 克的可编设力。
执行开路电压和阻抗测量将使用特定仪器。
