New Clarios Smart Battery for EVs, Autonomous Vehicles

Clarios Smart AGM will be a “game changer” for the industry, providing a reliable, safety-critical battery with real-time communications, says CEO Mark Wallace.


Clarios announced a new safety critical battery for EVs that will debut in the next two to three years. The company says it produces of one in three of the world’s car batteries.


Clarios Smart AGM (absorbent glass mat) will monitor its performance in real-time, deliver continuous low-voltage power to optimize performance of the low-voltage power supply, anticipate the need for battery maintenance and provide safety critical operations, the company says.

“The Clarios Smart AGM will be a game changer for the industry, providing a reliable, safety-critical battery with real-time communications,” said Mark Wallace, Clarios CEO. “It combines the proven reliability, inherent safe chemistry and sustainability of AGM with the real-time intelligence of our Smart technology. Also, it will extend our Clarios xEV portfolio, a range of advanced low-voltage batteries specifically designed to maximize EV performance, safety and reliability.”


Clarios says its AGM batteries are already used in OEM applications to handle the increasing electrical loads of today’s vehicles, which must meet growing consumer expectations for safety, comfort, and connectivity. EVs require an advanced low-voltage battery as a key component of a multi-battery system to help provide continuous low-voltage power and provide crucial safety functionality in critical moments of emergency. As more autonomous features are added to vehicles, there will be an even greater reliance on the low-voltage battery.

Smart AGM Advantages

Clarios says it Smart AGM provides superior functional safety performance to support vehicle reliability offering real-time communications that:

  • Identify potential issues in the battery before they happen, 
  • Provide emergency power critical for EV and autonomous vehicles, 
  • Anticipate required maintenance or replacement, and 
  • Optimize performance of the low-voltage power supply 

The Clarios Smart AGM provides the most reliable 12V power management system for the functional safety of critical vehicle operations, including advanced safety and autonomous applications, the company says. The Smart AGM battery is designed to reduce or eliminate internal failure modes, provide continued power supply operation with no leakage during crash events and monitor battery performance over time, supporting multiple vehicle use cases.


Currently 12V batteries are managed through an external sensor that is placed on top of the battery. With Smart AGM, Clarios developed an integrated approach to the electronics in the battery. 

“Smart AGM monitors its own performance in real time,” said Jason Searl, Clarios vice president Product Management. “The battery system senses, diagnoses and communicates the battery condition with the ability to support safety critical functions as well as anticipate required maintenance or replacement.”
