I was going through the FSAE International Rule-Book 2019 and encountered the term Tractive System Accumulator Container – Maintenance Plugs at section no. EV.3.3
I am actually a bit confused that what would the term Maintenance Plugs refer to? I guess it's not just some specific physical equipment but a general term, more like a category. When one reads the section, it reveals that somehow these plugs are allowing the electrical separations of the different segments of the EV's battery. But I don't exactly have a picture of its role in my mind.
If anyone can explain what these Maintenance Plugs are, it will be very helpful.
