Joule Heating in High-current Battery Clamps

This model analyzes a car battery-charger circuit where the cables and clamps are modeled using COMSOL Multiphysics. They experience high current that results in Joule heating, which in turn affects the conductivity of their materials.

Use of the SPICE Import Interface allows for two instances to be analyzed in the one simulation. You can analyze the potential and thermal distributions in the cables at both poles and at variable battery voltages, in a simultaneous sense.

CIRCUITS: A car battery-charger circuit where the cables and clamps are subjected to high currents that result in Joule heating. The color plot on the clips shows the temperature distribution, illustrating the much higher temperature at the positive pole.
