新能源汽车用能源系统 技术领域
本发明涉及新能源汽车用能源设备技术领域，尤其涉及一种新能源汽车用能源系统。
背景技术
当今社会，随着人们生活水平的不断提高，对汽车的需求越来越多，同时，能源问题不断加深，石油产品逐渐紧缺，而对环境的污染也不断加深。如何能行之有效的制造一种替代传统汽车的新能源汽车，成为当今所有汽车企业的发展目标。而且，国家对新能源汽车产业的大力扶持，也正是出于这一目的。新能源汽车又可以被分为纯电动汽车和混合动力汽车，但不论是哪一种，都离不开动力电池为其提供动力。而作为能源的动力电池，由于其本身的特性，在使用过程中需要通过串联或并联的方式增加电池包的能量及电压，如何将电芯通过结构设计满足其串并需求便成为新能源汽车研发的一大方向。
电动车的电池包一般布置在汽车底部的电池包壳体内。电池包壳体，对上需要承载电池，保护模组，完成能量输出的任务；对下，其作为汽车的底部外壳，需要面对石子击打，淋雨，冲击等外部危害。这就要求电池PACK需要具有高强度，能够应对各种外界影响，同时由于电池的重量已经很大了，电池PACK壳体需要重量轻，这样能够提高车辆操控，增加续驶里程。而现有电动车的电池模组壳体强度够的板体底板厚度大，质量大；质量小的，强度小。
同时，在电池包中，电池模组通过高压线缆连接后，需要输出至包外，提供给负载设备。在电池模组与负载之间，需要引入控制模块，控制模块通常包含继电器、保险、维修开关等控制零件，这些控制零件一般分散在电池包内各处，在电池包使用过程中，一旦电池包发生晃动，这些控制零 件就会在电池包内移动，而这些控制零件的移动容易引起连接线脱落，正、负极器件连接线短路相接等问题，这些问题严重影响着电池包的功能和使用安全；如何妥善安置这些控制零件，确保电池包的正常使用并保障其安全，成为电池包设计中亟待解决的问题；同时电池包安装时各控制零件需要分别与电池包或用电器内其他器件连接，连接麻烦，且电池包组装效率低。
再次，电池模组作为单体电芯的上一级总成，是连接单体电芯和电池包的中间结构，其设计好坏显著影响电池包的性能发挥。锂离子电池模组型锂离子电池中的单体电芯容量大，所以重量较大，组成模组需要具有较高强度的结构。同样由于18650单体电芯容量大，容易造成比表面积不足，需要更好的散热条件。同时为了满足能量密度需求，成组的固定结构越轻越好。然而目前的18650锂离子电池模组无法满足上述要求。
因此，为了解决上述问题，急需发明一种新的新能源汽车用能源系统。
