化成又叫活化，为电池制造后，通过一定的充电方式将其内部正负极物质激活，改善电池综合性能的过程。化成是一个非常复杂的过程，同时也是影响电池性能很重要的一道工序，因为在电池首次充电过程中，不可避免地要在碳负极与电解液的相界面上形成覆盖在碳电极表面的钝化薄层，称之为固体电解质界面膜或称SEI膜。为了形成良好的SEI膜及高的生产效率，一般需要用化成柜控制实现由小到大阶梯电流方式进行充电管理筛选。

如下是CA433在化成柜上的应用：

由于未化成的锂电可能存在不良风险，有化成时电流过流等可能，虽然化成柜上有过流保护电路，但一般这些保护电路都是通过MCU采样检测到锂电端过流，然后去控制MOS管或继电器的通断来实现过电流的保护。这种保护是通常所说的软保护，没有实现真正的物理断开，有一定安全隐患。如当过流发生的同时，控制MOS或继电器通断的MCU发生软件方面的故障，不能发出断开回路的命令时，电路产生的热量极有可能会导致化成设备电路的损坏，甚至起火。此时推荐在电路上串上保险丝（如CA433）就能实现完全的物理断开，可以有效防止此危险的发生。

CA433的外形如下图：

其特点如下：

1、电流0.2-30A可选

2、电压1000V/660V/600V500/300V AC/DC可选

3、高分断能力

4、6x32MM插件封装，已经通过UL认证，认证号为E500586

5、宽工作温度范围-50℃ ~ +125℃

6、Rohs环保，无卤素、带引线不带引线可选

【应用】电安科技小尺寸高压陶瓷插件保险丝HV323-A040P2成功应用于OBC的短路保护上

有个便携式6.6KW的OBC，输入电压100-240Vac，考虑到用户家里一般都有空开，所以没有串保险丝，在250-900VDC输出端，平时设计电流16A，需要选一个40A 1000VDC的尽量尺寸小，价格有优势的熔断器，做输出短路保护，分断要求20KA。给客户推荐了我们14x39mm的高压陶瓷插件保险丝HV323-A040P2。

【应用】贴片保险丝SF303成功应用于PD充电器的过流保护上，表面贴装2410封装，公制尺寸6.1x2.5MM

如传统充电器在空间尺寸上没有体积要求，一般在交流AC输入端都串联方型插件的保险丝，来满足过流、短路保护的安规要求，但PD充电器由于体积要求的限制，在保险丝选择方面，工程师们一般都倾向于选择贴片系列的保险丝，如电安的SF303系列，它是2410封装，公制尺寸6.1x2.5MM，串在AC输入端，其焊盘间距尺寸正好能满足安规爬电距离的要求。

The Cartridge fuse CA433 of DA Technology has been successfully applied in the overcurrent protection of the lithium battery formation system

When the overcurrent occurs, the MCU that controls the on and off of the MOS or relay has a software failure and cannot issue a command to open the circuit. The heat generated by the circuit is very likely to cause damage to the circuit of the formation device, or even fire. At this time, it is recommended to put a fuse (such as CA433) in series on the circuit to achieve complete physical disconnection, which can effectively prevent this danger from occurring.
