modelLiIonBattery
Information
Hypothesis and equations
The model is composed of a Li-ion battery + converters + inverter system.
It takes into account the static losses, the charging and discharging efficiencies and the ,no-load consumption of the converters and the BSM.
The currents are limited by the charge and discharge currents admitted by the battery and by the power of the inverter.
By default, the maximum charge and discharge currents are taken equal to Cmax and 2Cmax respectively (Saft type battery).

Known limits / Use precautions
The input setpoint power must be negative if you want to store it, positive if we want to destock.
The output power of the battery correponds to the stored power if it is positive, destocked otherwise.
