Inspection in Assembly of Li-ion Battery Packs for EVs

Open-circuit voltage (OCV) testing. A battery''s voltage is known as the open-circuit voltage (OCV) when it is not connected to any load. OCV values gradually decline due to self-discharge, a characteristic of batteries. When a battery has an internal defect, self-discharge increases, causing the OCV to increase beyond the defined value.
