Description
技术领域
本专利申请要求于2020年10月29日提交韩国专利厅的韩国专利申请第10-2020-0142461号的优先权，上述专利申请的公开内容引入本说明书中作为参考。
本发明涉及电动汽车用冷却液组合物。
背景技术
为了控制电源工作过程中产生的热量，利用与电源热连通的传热系统。例如，汽车采用传热流体及冷却系统来传递并释放作为内燃发动机副产品产生的热量。在这种情况下，传热流体及冷却系统确保发动机在最佳环境中进行工作，防止发动机暴露在不适合的高温环境中。
然而，当前需要代替现有汽油内燃发动机的替代品，尤其是那些解决公众对环境和天然资源管理的担忧的替代品。结果，需要持续开发新的电源技术，尤其是那些改善能源效率的技术。作为已开发的替代电源的一例包括但不限于电池、燃料电池、太阳能光伏电池及以蒸汽冷凝、天然气、氢等为动力的发动机。这些替代电源可单独使用或组合使用，例如是在混合动力车辆中采用的电源。
虽然这种替代电源通常提供比汽油内燃发动机更高的能源效率，但是仍需要使用传热系统及传热流体。尤其，对于传热系统及传热流体而言，温度对于维持最佳工作条件至关重要。
用于电动汽车的锂二次电池不仅需要高能量密度和能够在短时间内大功率输出的特性，而且需要在短时间内以大电流反复充放电的恶劣条件下能够使用10年以上，因此，必然需要比现有的小型锂二次电池显著优秀的稳定性及长寿命等特性。尤其是用于解决锂离子电池在使用过程中产生的热量问题的冷却技术成为重要课题。
但是，现有的冷却系统及传热流体不适合与替代电源，尤其是采用电力或电荷的替代电源一并使用。例如，现有的传热流体的特征在于通常具有非常高的电导率，其电导率大致在3000uS/cm以上的范围内。若将高电导性的传热流体与替代电源，尤其是基于电的替代电源一并使用，则有可能导致电击、腐蚀加剧和/或电路短路。
结果，现有的传热流体不适合与替代电源，尤其是基于电的替代电源一并使用。

实验例1.金属腐蚀评估
根据ASTM D 1384标准对车辆用部件材料的防蚀性进行了评估。具体地，使用符合标准的试片组并利用腐蚀性组合水(硫酸钠148ppm、氯化钠165ppm、碳酸氢钠138ppm)，将冷却液浓度稀释为33％后，在88℃的温度条件下评估336小时，其结果如表3所示。(液相结果表示试验结束后离心分离产生的沉淀量，将试验结束后的沉淀生成量(vol％)为0.1以上的情况标记为产生沉淀)
表3
如表3所示，可确认到实施例1至实施例6及比较例5至比较例8的所有试片中均未产生腐蚀或沉淀。
实验例2.通电评估
用作电动汽车动力源的电池由电芯、模组、电池组构成。一个电芯为3.75伏，多个电芯串联成一个90伏的模组单体，模组数量根据车辆设计调节，可通过串联并联组合构成车辆的电池组。因此，确认冷却液对电池构成单元中的模组电压造成的影响。
具体地，利用蒸馏水将实施例及比较例中制备的冷却液分别稀释成50重量百分比。接着，将用作电池部件的10针连接器(母(female))浸入稀释的冷却液中后，向上述10针连接器施加90V的电流4小时以上。随后，切断电流，确认10针连接器产生的物质量，根据表4的结果显示标准，将结果示于表5中。

如表3所示，可确认到在上述实验例1中结果良好的实施例1至实施例6及比较例4至比较例8中的实施例1至实施例6的结果良好，尤其，实施例1、实施例2、实施例4及实施例5未产生足以堵塞针孔的析出物。虽然比较例4至比较例8的金属腐蚀评估结果优秀，但是，在通电评估中确认到针孔被析出物堵塞。
