Littelfuse为电动汽车电池管理系统保护提供绝佳解决方案
在电动汽车应用中，考量电池管理及其电路设计中的关键因素以及选择合适的电路保护器件在电池管理系统中显得尤为重要。就在如何考虑其中的因素的问题上我们资深应用技术工程师杜尧生给出了参考答案。近几年，电动汽车受到国家政策扶植和消费者的青睐，市场热度持续增长。作为电动汽车的三大核心系统之一，电池管理系统(BMS)旨在智能化管理和维护各个电池单元，防止电池出现过充和过放，监控电池状态，延长电池的使用寿命。
业界认为，发明电池管理系统是一个创举，以前从来没有把几千块甚至上万块电池放在一起统一管理使用。电池管理系统需要对每一个电池单元做到精准的监测，涉及最关键的因素就是安全性。这也是汽车使用者和设计者都必须关注的重点。
LITTELFUSE 作为一个安全可靠的电路保护器件供应商，目前大量的产品已经用于电动汽车的电路保护中，尤其是电池管理系统，包括每一个电池单元管理，整个通讯管理，再到整个电池系统管理，实现从点到面到中间的联系，整个通路都进行了系统、完整的防护设计。 Littelfuse 也是最早参与设计或制定电池管理系统安全防护的厂家之一，产品满足AECQ200测试的标准要求。在此标准下，Littelfuse相当于在每一路增加了一颗采样的保险丝，和浪涌防护的TVS大大加强了整个电池管理系统的安全性。
针对电池短路问题，可以说，任何一个环节出现短路，或者电池内部短路机理的出现，厂家都可以通过绝缘膜或隔离的器件提供保证。Littelfuse 电路保护元件产品也针对外部短路设计，因为每一个在外部可能产生短路环节都需要保护。
如何选择合适的电路保护元件？
多数情况下，电路保护元件在做样机、实验时都没有问题，一旦批量化就出现质量的瑕疵或安全隐患，实际上这需要考验大批量、大规模生产的能力。Littelfuse作为一家百年老店，一贯制造可靠、稳定的大批量产品，致力于打造高品质、有保证的品牌。
杜尧生表示，品牌就是品质的保证，因为品牌可以提供一贯长期稳定的服务。当出现问题的时候，能有根有源地找到症结。与一流的厂家、一流的品牌合作，才能得到一流的产品设计与服务。 在电动汽车电池管理体系应用中，电路保护元件的选择有哪些因素或标准需要考虑？杜尧生给了我们三点参考。 第一是必要性，电路保护元器件是必不可少。第二是合理性。众多电路保护元器件产品中，选择一款适合自身设计的保护器件很重要。第三是前瞻性。在设计新产品时，要与厂家保持密切配合，了解未来产品的发展方向，开发出具有前瞻性的产品。 Littelfuse 始终把安全可靠的产品设计放在首位，这也是电路保护产品的核心要素，没有安全的基石，其他都将是空中楼阁。相信这也是为什么Littelfuse 在竞争日益激烈的当下，始终引领市场的原因。相信将来会有更多的Littelfuse 产品在不同的应用场景中出现，为产品安全运行提供可靠保障。

开关电源中，如何选用保险丝的电流？
一是看电路的最大持续工作电流，二是看工作环境温度，三是所选保险丝的认证情况，比如UL认证的保险丝折减率是75%。保险丝的额定电流=电路最大持续工作电流/（温度折减率*保险丝认证折减率），举个例子，电路的最大持续工作电流为2A，工作温度最大为80℃，对应保险丝的温度折减率为88%，UL认证，2A/（0.88*0.75）=3.03A，则所选保险丝的额定电流应大于3.03A。Littelfuse作为保护器件的大品牌，保险丝种类丰富，认证齐全，可以在平台搜索了解详情，有具体需要可以提选型帮助，保险丝不光只看电流的。

【技术】Littelfuse解析保险丝及其应用注意事项
保险丝作为过流保护器件，在电子行业得到普遍应用，存在感非常强，却又那么不起眼，只要不是全新的设计方案，只要没出问题，经验的沿用以至于很多硬件工程师对于保险丝的参数与选型不明所以。Littelfuse浅显易懂地讲述保险丝及其应用注意事项，供有需人士参考。
