Yes, you are right. I didn't notice that it's called battery control in 45e. So, indeed according to the 50e owner's manual "BATTERY HOLD is used to maintain the current charge level of the high-voltage battery. The electric range can be conserved in this way for a later point in the trip, for instance." And according to the 45e owner's manual "with BATTERY CONTROL, the electric range can be maintained and conserved for a later point in the trip or increased as needed" (the key word being "increased").
