100 VAC/120 VAC source
250 V, 5 A, time delay
Explanation
Equivalent series resistance
Open-circuit voltage
Terminal voltage
Unit for battery capacity
State of charge
A profile of a battery that contains the information for Voc and ESR in different
states of charge
The voltage of the battery when it is fully charged
The voltage of the battery when it is fully discharged
During the dynamic battery simulation, the open voltage and SOC change with
the charging and discharging
During the static battery simulation, the open voltage and SOC stay the same
(on page 2-61).
