Description
This block models a battery cooling plate with flat channels. Use the buildBattery
function to create a Simscape model of a battery and
connect it to one or both sides of the cooling plate. The fluid_in
and fluid_out ports are thermal fluid ports. The output ports are
the plate temperature, Tp, the fluid pressure drop,
dP, and the fluid temperature change,
dT.
