就IEC60950而言,我个人认为根据3.1.1下面的这段话,应该是要有overcurrent protection的,当然不一定是保险丝
All internal wiring (including busbars) and INTERCONNECTING CABLES used in the distribution of
PRIMARY CIRCUIT power shall be protected against overcurrent and short-circuit by suitably
rated protective devices.
但是下面还有一段
Wiring not directly involved in the distribution path does not require protection if it can be
shown that creation of hazards is unlikely (for example, indicating circuits).
也就是说,如果你的充电器不合电网直接连接,而且是不可能产生危险,应该就是可以不用了。
