January 13, 2025: Clarios announced on January 6 it had secured a significant contract with a major automotive manufacturer to supply its advanced supercapacitors in a 12V and 48V architecture.

The lead batteries major did not disclose details of the deal, but said supercapacitors are designed to store and dispense bursts of high power, suitable for functions like steer-by-wire, adding minimal weight to vehicles.

Clarios said the enhanced system delivers on-demand power in any circumstance, which is especially critical for functional safety features and capable of providing a short burst of power in chassis systems — such as keeping the vehicle level when at high speeds around a turn.

The supercapacitors are complementary to AGM batteries in these vehicle applications and to the overall system architecture to provide power stabilization, fuel efficiency improvements through regenerative braking and redundancy for safety.

Clarios said the milestone agreement underscores industry confidence in the company’s innovative technology.

The contract follows last month’s announcement that Clarios’ Connected Services business unit had signed its first commercial agreement with a European fleet operator for a product aimed at reducing idling times in heavy-duty vehicles.

Claris said previously that the unit represented a new era of battery intelligence to transform the management of vehicle power systems.
