储能电池在光伏系统中是不可缺少的一部分，主要用于存储光伏系统在工作时产生的电能，在日照量不足、夜间以及应急状态下提供电能。电池的寿命是有限的，为了提高电池的利用率，需要在光伏系统和电池包之间增设一块保护板，基本功能包含过流检测、过充检测、过放检测、输出电路保护。

如下图1所示，电池保护板对充放电时的电压和电流进行实时检测，当超出阈值时关闭MOS管，断开电池包和光伏系统的连接，从而保护电池包，提高电池的利用率，保险丝则作为第一级保护，在瞬时电压或者电流过大时熔断，保护后端器件以及电池包，本文主要介绍国产厂牌竞沃的三端保险丝 WSFD4550用于光伏储能电池保护板上的优势。

图1 电池保护板基本框图

三端保险丝可同时做过压和过流保护，设计简单，保护效果好，在各类电池的保护板均有应用。国产厂牌竞沃的三端保险丝WSFD4550的应用优势如下：

1、熔断时间快，在工作范围内，熔断时间小于1min；

2、阻值范围在0.7mΩ~2mΩ，可减少充放电时的损耗；

3、采用贴片封装，可节省PCB面积，优化成本；

4、竞沃作为国产厂牌在国内自有研发实验室以及生产工厂，性能优秀，交期以及成本都能给到客户以便利。

一次性保险丝和可恢复保险丝有什么区别？

一次性保险丝一般由三部分组成：主体是低熔点的金属丝或者金属薄片制成的熔体，是熔断器核心；电极端头连接电路与熔体，具良好导电性；支架，固定熔体并使三部分成为刚性的整体。两种保险丝都可用来做电路的过电流保护，其使用的不少领域和场合有类似，有一部分场合这两种产品都可以使用，还可以互相替换。例如在过流保护要求不太高的电池保护应用中这两类产品都能各领风骚。在对某些IC等重要器件保护应用中，或电源的输入/输出端就只有一次性保险丝才有可能胜任其保护功能，这些部位对阻抗要求也较高。另外在一些一旦发生故障就必须停机检修排除故障的场合，也要求使用一次性保险丝。而一些必须避免因过热而烧坏产品的场合，经常需要热插拔操作的接口过流保护，可简易排除故障，以及非器件故障导致的暂时性过电流的电路保护则应该选择可恢复保险丝。
