Model Parameters:
C is the amp-hour battery capacity [Ah]
– e.g. C = 0.3, 1.4, or 2.8 [Ah]
NS is the number of cells in series
– e.g. NS=1 for 1 cell battery, NS=2 for 2 cells
+ - LI-ION_BATTERY battery (battery voltage is double from 1 cell)
TSCALE = 1
U1 C = 1.4 SOC is the initial state of charge in percent
SOC = 1 – e.g. SOC=0 for a empty battery (0%), SOC=1 for
a full charged battery (100%)
NS = 1
(Default values) TSCALE turns TSCALE seconds into a second
– e.g. TSCALE=60 turns 60s or 1min into a second,
TSCALE=3600 turns 3600s or 1h into a second,
• From the Li-Ion Battery specification, the model is characterized by setting parameters
C, NS, SOC and TSCALE.
