Abstract: A high voltage battery module includes a plurality of battery cells, a plurality of cooling fins dispersed between the battery cells, and a frame for holding the plurality of battery cells and the plurality of fins. An intumescent layer is proximate to at least one battery module component selected from the battery cells, the plurality of cooling fins, and the frame. The intumescent layer includes sodium silicate having formula Na2SiO3, pentaerythitol, a resin that is cross-linked by melamine, boron nitride particles, and triammonium phosphate.

Abstract: A method and a test fixture for evaluating a junction between an electrical lead trace and a busbar are described, and include an electric power supply disposed to supply electric power to the electrical lead trace and an electric monitoring device disposed to monitor electrical potential across the junction. A mechanical stress-inducing device is disposed to apply mechanical stress proximal to the junction. The electric monitoring device monitors the electrical potential across the junction of the electrical lead trace coincident with the mechanical stress-inducing device applying mechanical stress proximal to the junction when the electric power supply is supplying electric power to the electrical lead trace. Electrical integrity of the junction is evaluated based upon the monitored electrical potential across the junction.
