This model represents the charge/discharge mechanism of a battery.
This model two parameters ηCHA and ηDIS that represent the efficiency during the charge and discharge of the battery.
The model given the power P that should be provide or taken from the battery and compute the actual power flowing through the battery as
Equation | Condition |
---|---|
Pactual = P ηCHA | P ≥ 0 |
Pactual = P / ηDIS | P < 0 |
The actual power is then used to compute the variation of the state of charge SOC
.
The state of charge is the state variable of this model and is a real value between 0 and 1.
d SOC / dt = Pactual
Note:The input power P has to be controlled in order
to avoid the state of charge SOC
exceeding the range between 0 and 1.
