Charged EVs | Clarios acquires Maxwell Applied sciences to advance its supercapacitor portfolio

Clarios, a provider of low-voltage vitality storage options, has introduced the acquisition of Maxwell Applied sciences, a producer of supercapacitor cells and modules. Clarios says this acquisition will improve its place in high-performance, short-duration vitality storage. Particular phrases of the transaction haven’t been disclosed.

Maxwell Applied sciences’ supercapacitors are engineered to supply fast charging and discharging, dealing with as much as 1 million cycles and working throughout a temperature vary from minus 40 °C to 65 °C. Clarios says that these modules require no upkeep or further fire-risk mitigation, addressing reliability and longevity challenges in vitality storage designs.

In 2019, Tesla acquired Maxwell Applied scienceswhich many believed had much less to do with its pioneering work with supercapacitors (aka ultracapacitors) than with its “dry electrode” know-how—a far less complicated option to make the anodes and cathodes that type a battery cell.

In 2021, UCAP Energy, a San Diego-based developer of ultracapacitor-based energy options, bought the Korean-based ultracapacitor enterprise of Maxwell Applied sciencestogether with different associated property, together with the Maxwell model.

Clarios states that integrating supercapacitor know-how helps its provide chain stability for each US and world unique tools clients, particularly inside the EV and broader mobility sector. The acquisition additionally aligns with Clarios’ give attention to battery circularity and low-voltage vitality storage innovation.

Along with purposes in automotive programs, Maxwell Applied sciences’ supercapacitors are additionally utilized in grid stabilization, energy for information facilities, vitality era, army, transportation and industrial automation. Maxwell has shipped over 85 million supercapacitor cells to this point, in keeping with Clarios.

“Maxwell’s supercapacitors are designed to supply clients with high-power vitality storage options that emphasize reliability, security, and lengthy life,” mentioned Mark Wallace, CEO of Clarios. “This integration strengthens our capability to serve our automotive clients and creates a long-term alternative to increase our presence in non-automotive sectors. Maxwell’s present buyer relationships in Knowledge Facilities, Grid, Navy and Industrial purposes can be maintained and actively developed underneath Clarios’ management.”

Clarios will function Maxwell Applied sciences as an unbiased, US-based enterprise unit.
