Revolutionizing EV Battery Technology
General Motors is joining a trend among automakers and battery manufacturers to innovate electric vehicle (EV) technology through mixed-chemistry battery packs. A recent patent application, revealed by the United States Patent and Trademark Office, details GM’s ambitious plans to integrate nickel manganese cobalt (NCM) with lithium iron phosphate (LFP) and similar battery chemistries.
This proposed technology involves creating distinct modules within the battery pack, each with varying capacities, allowing for sophisticated monitoring of conditions like temperature and charge levels. Such a system would enable the battery to selectively rely on either chemistry based on current needs, enhancing performance and efficiency.
By marrying the high energy density of NCM cells with the cost-effective nature of LFP cells, GM aims to improve both the affordability and functionality of EVs. While different chemistries can initially create a charging imbalance, GM’s innovative design may mitigate this issue, optimizing the charging process.
Other automotive pioneers are also exploring this avenue. For instance, CATL is developing faster-charging battery solutions for plug-in hybrids, while the startup Our Next Energy showcased a mixed-chemistry battery capable of extending a BMW iX’s range to an impressive 600 miles. Furthermore, Mercedes-Benz has engineered components to further advance the use of diverse battery cell types. This collaborative momentum points towards a promising future in electric mobility.
