B737 NG electrical
Hello,
small questions about electrical system for the NG.
When the battery charger operates and charges the battery, does it also continue to feed the hot batt and switched hot batt busses? Or does it just charge the battery and the battery powers those busses?
Now, you decide to use the BATT position , what happens?
Does that mean that the battery will feed the corresponding busses or that the battery charger will do it if it is available?
I read that, in this situation, charging of the battery is inhibited.
I also read that in case of thermal runaway, hot batt and switched hot bat busses are lost. On the schematics, it is not clear. Initially, I thought that the battery charger will be disconnected from the battery but would continue to feed the hot batt and switched hot bat busses...
Thanks
