Automotive batteries represent the cornerstone technology enabling the transition from internal combustion engines to electric propulsion systems. These sophisticated energy storage devices convert chemical energy into electrical power, providing the primary energy source for electric vehicles (EVs) while also supporting hybrid systems, start-stop functionality, and the growing array of electronic components in modern vehicles.
Unlike traditional lead-acid starting batteries designed primarily for engine ignition, modern automotive traction batteries must deliver sustained high power output, rapid charging capability, thousands of discharge cycles, and energy densities sufficient for practical driving ranges. These demanding requirements have driven remarkable technological innovation across multiple chemistries, cell designs, thermal management approaches, and battery management systems.
