The Charger component models a battery charger with settable current and voltage limits. The charging current is constant, ${\mathrm{I}}_{\max }$, until the nominal charging voltage, $V_{\mathrm{nom}}$ is reached, at which point that voltage is maintained. The charger will not sink current.

An optional heat port senses the battery temperature. If the heat port is enabled, a specified temperature coefficient ($\mathrm{TC}$) adjusts the charging voltage with temperature.

An optional boolean input turns the charger on and off.
