大家能否讨论下各家做60335-2-29 电池充电器带载到底是否要求一致：
充电器可以给锂电池及铅酸电池充电，输出超过20VA，是否输入和温升都要分别带载101网络以及最大容量电池测试
另外3.19里面说的Other battery chargers 是指哪一类电池，这个理解也有不同
8 @- p: k0 n/ H0 d据我了解 每个实验室要求都不同，所以还是有讨论的必要的:(

兄弟，你的问题深奥啊，额定直流输出电流不大于20A的充电器都要按照101网络和最大容量的电池做吧，两种状态都要做，个人理解；其他超过20A的充电器的按照说明书上要求最大容量的已经放电的电池来做测试，就不用接101网络了，个人理解。
