Experimental investigation of the influence of electrical contact resistance on lithium-ion battery testing …
As cells are irreversibly connected in a battery pack, electrical contact resistance (ECR) is usually in the magnitude of <1 mΩ, and thus far lower than in reversible contacts during lab-testing. An interesting question arises as to whether this ECR has any unintended influence on the battery cell during testing.
