Description

电池箱、动力电池总成及车辆
本申请要求于2022年3月24号申请的、申请号为202210303456.X的中国专利申请的优先权。
技术领域
本申请涉及动力电池技术领域，特别涉及一种电池箱、动力电池总成及车辆。
 背景技术
目前，随着各项政策的支持，以及各车企的不断投入，电动汽车已逐渐成为汽车工业发展的重要方向。在电动汽车中动力电芯模组是非常重要的组成部分之一，其直接关系到整车续航与成本等核心问题，所以对模组的设计改进成为车企及动力电池生产厂家的重点研究内容。在追求电芯模组能量密度，以延长整车续航能力的同时，动力电池包的安全问题也随之出现，其中，动力电池的热失控是当下面临的主要安全问题，因而采取适宜措施以应对热失控就成为提高动力电池包安全性的重要手段。
主流电动汽车动力电池按照VDA（德国汽车工业协会）标准模组进行集成，电池系统内部系统级热失控防护设计，一般的方法仅是在标准模组外部额外增加独立防火隔热层、配合系统级泄压防爆及整车报警功能来实现，但这种设计思路实际的热失控防护结果受各种因素影响偶然性较高，随着电芯电化学体系的发展只能满足较低标准的热失控防护需求。
 技术问题
本申请实施例提供一种电池箱，本申请实施例还提供一种具有上述电池箱的动力电池总成及具有上述动力电池总成的车辆。
 技术解决方案
第一方面，本申请实施例提供一种电池箱，包括箱体和盖体，箱体设有用于容纳电芯模组的容纳空间，容纳空间具有一开口。盖体盖设于开口，并与箱体连接，以将电芯模组密闭在容纳空间内；其中，盖体包括本体以及隔热防护层，本体连接于箱体，隔热防护层覆盖于本体背离容纳空间的一侧。
第二方面，本申请实施例还提供一种动力电池总成，包括电芯模组、上述任一项的电池箱以及控制模组。电芯模组位于容纳空间内，控制模组电性连接于电芯模组。
第三方面，本申请实施例还提供一种车辆，包括底盘以及上述动力电池总成，动力电池总成设置于底盘。
 有益效果
相对于现有技术，本申请实施例提供的电池箱中，电芯模组位于容纳空间内，箱体和盖体对电芯模组起到保护作用。若电池箱应用于车辆的动力电池总成，电池箱的盖体直接作为车辆地板的组成部分，当电芯模组发生热失控后，电芯模组散发热量，热量传导至盖体上，位于盖体外侧的隔热防护层能够在一定程度上阻隔盖体热量，避免热量传导至乘客或者车辆的座椅，影响乘客使用感，提高电安全防护。

请同时参阅图1和图2，本申请实施例提供一种配置有电池箱100的动力电池总成200以及电池箱100，其中动力电池总成200包括电池箱100以及电芯模组201，电池箱100用于放置电芯模组201，以为电芯模组201提供防护。
电池箱100包括箱体10以及盖体20。箱体10可以为具有底壁的壳体结构，其设有用于容纳电芯模组201的容纳空间12（如图3所示）。容纳空间12具有开口121。盖体20盖设于开口121，并连接于箱体10，以将电芯模组201密闭在容纳空间12内。箱体10和盖体20共同对电芯模组201提供防护，提高安全性能。
请同时参阅图4和图5，在本实施例中，盖体20可以包括本体21以及隔热防护层23。本体21连接于箱体10且盖设于开口121处，其大致呈矩形板状，本体21为金属板，采用钣金冲压工艺制成。
隔热防护层23覆盖于本体21背离容纳空间12一侧的表面，隔热防护层23采用具有隔热性能的材料制成。在一些实施例中，隔热防护层23可以为隔热涂层，其可以涂覆于本体21背离容纳空间12一侧的表面，也可以全覆盖于本体21的所有表面。隔热涂层的涂料选用隔绝传导型隔热涂料，例如复合硅酸镁铝隔热涂料、稀土保温涂料等硅酸盐系涂料。阻隔型隔热涂料是通过涂料自身的高热阻来实现隔热的一种涂料，属于厚膜涂料；涂装时厚度一般取值在5mm-20mm之间（含端点），涂刷1-20遍。经过充分干燥固化后，由于材料干燥成膜后热导率很小，因此涂层具有一定的减慢热流传递的能力，达到阻隔本体21热量的效果。
在另一些实施例中，隔热防护层23可以粘贴于本体21，并覆盖于本体21背离容纳空间12一侧的表面。本说明书对隔热防护层23的具体结构不作限制，在本实施例中，隔热防护层23为高温相变材料层232，高温相变材料层232包括以下固-固相变材料中至少一种：多元醇类、高分子类、层状钙钛矿类。若高温相变材料层232包括多层固-固相变材料，则多层材料可以层叠粘覆于本体21，例如，多层材料可以包括第一层、第二层、第三层等等，第一层直接粘附于本体21，第二层粘附于第一层、第三层粘附于第二层，以此类推。电芯模组201发生热失控后，温度通过本体21传导至高温相变材料层232，高温相变材料层232吸收热量，发生相变，达到一定程度阻隔本体21热量的效果。
请参阅图6，在实际应用中，盖体20可以直接作为车辆300（请参阅图10）的地板的组成部分，用于直接承载车内部件如座椅等，还可以用于直接承载乘客。基于此，盖体20可以具有不同的功能区域，不同的功能区域的结构或/及防护设计可以不相同，以在保证满足足够的防护需求的同时，适当地控制制备成本。例如，在一些实施例中，盖体20可以包括用于承载车辆300的座椅的承载部214以及供乘客踩踏的踩踏部216，承载部214上的隔热防护层23的厚度小于踩踏部216上的隔热防护层23的厚度，以便于车辆300的座椅的安装，并在一定程度上降低成本。隔热防护层23一定程度上阻隔本体21的热量，避免热量传导至乘客或者车辆300的座椅，影响乘客的使用感。
具体而言，请参阅图7，承载部214可以包括第一承载部2141、第二承载部2143、第一踩踏部2161以及第二踩踏部2163。第一承载部2141用于承载车辆300的后座椅，第二承载部2143用于承载车辆300的前座椅，第一踩踏部2161设置于第一承载部2141和第二承载部2143之间，第二踩踏部2163位于第二承载部2143背离第一承载部2141的一侧。隔热防护层23可以包括两个第一隔热部232以及两个第二隔热部234，两个第一隔热部232分别覆盖于第一承载部2141和第二承载部2143，两个第二隔热部234分别覆盖于第一踩踏部2161以及第二踩踏部2163；第一隔热部232的厚度小于第二隔热部234的厚度，便于车辆300的座椅的安装。
请再次参阅图4和图5，在本实施例中，盖体20还可以包括第一隔热绝缘层25。第一隔热绝缘层25设置于本体21朝向容纳空间12的一侧，本说明书对第一隔热绝缘层25的具体结构不作限制，例如，第一隔热绝缘层25可以包括云母板、陶瓷纤维、耐高温胶带、耐高温泡棉等耐高温绝缘的材料中的至少一种，在本实施例中，第一隔热绝缘层25包括云母板或/及气凝胶垫。第一隔热绝缘层25在电芯模组201热失控后对本体21进行隔热绝缘，一定程度上避免本体21的温度过高。

请再次参阅图2和图3，在本实施例中，箱体10可以包括底壳16和支撑框14，底壳16和支撑框14组装连接，并共同形成容纳空间12。底壳16取消了传统电池箱箱体底板加液冷板的组合，直接采用液冷板161作为电池箱100的底部。液冷板161采用一体钎焊板，在本实施例中，其总厚度取值在5mm-8mm之间（含端点）。本说明书对液冷板161和支撑框14之间的具体连接方式不作限制，液冷板161和支撑框14之间的连接结构可以为直接连接，例如液冷板161和支撑框14可以采用焊接连接，也可以采用螺栓连接，在本实施例中，液冷板161和支撑框14采用热熔自攻丝工艺连接。

在一些实施例中，电池箱100还可以包括导热胶层30，导热胶层30连接于底壳16和电芯模组201之间，用于固定电芯模组201。导热胶层30涂覆于第三隔热绝缘层29背离底壳16的一侧，其厚度取值在0.8mm-1.2mm之间（含端点）。导热胶层30不仅能起到固定电芯模组201的效果，也可以满足导热性能，还能够提升热安全性。
