As the rapid advancement of electric vehicles (EVs) and electronic systems transforms automobiles from mere transportation tools into intelligent "smart mobility" solutions, vehicle systems are becoming increasingly sophisticated and complex. Features such as advanced driver assistance systems (ADAS) for safe driving support, telematics control units (TCU) for communication functions, automated emergency call systems (eCall) for automatic accident reporting, and various sensors monitoring surrounding environments, including tire pressure monitoring systems (TPMS), are now integral parts of modern vehicles.
These onboard systems rely on vehicle batteries to operate reliably. They are essential not only as drive power sources but also for instantaneous power supply to in-vehicle devices such as electronic control units and sensors. As a pioneer in automotive Lithium-ion batteries, Panasonic Energy leads the industry with cutting-edge technology while also providing Lithium primary batteries and Nickel-metal hydride batteries as power sources for in-vehicle devices.

Future automobiles will run on electricity, think with electricity, and be protected by electricity—moving toward an era where battery technology, like that developed by Panasonic Energy, is evolving to the next stage.

【Application Examples】
TPMS: This system monitors the tire air pressure of a vehicle and alerts the driver in case of abnormalities. It helps maintain tire safety and fuel efficiency, thereby preventing accidents. As a core component, batteries used in TPMS are required to be high-performance and highly reliable. Panasonic Energy supports systems with batteries that can operate acros a wide temperature range. 

TCU/eCall: To enable swift emergency responses during accidents, the installation of vehicle emergency call systems (eCall) and Telematics Control Units (TCU) is expanding. These systems demand batteries that can reliably function over long periods and under various environmental conditions, ensuring safety and trustworthiness. Panasonic Energy supports systems with safe and reliable batteries that can operate across a wide temperature range. 

Remote Keyless Entry (RKE): Remote Keyless Entry (RKE) is evolving from traditional button-based remotes to more advanced systems that feature smartphone connectivity and passive entry functions. These advancements require batteries in RKE systems to play an increasingly important role, balancing convenience and security. Panasonic Energy provides batteries with excellent pulse discharge characteristics that can operate across a wide temperature range.
