Exponent Energy unveils 15-minute quick EV battery charging solution
The technology underlying Exponent Energy's 15-minute quick electric charging solution for
electric vehicles
(EVs) has been made public. The business demonstrated its proprietary energy stack, which consists of the e^pack (battery pack), e^pump (electric charging stations), and e^plug (charging connector). These components work together to enable a 15-minute rapid charge and, for the first time, extend battery life (with a 3000-cycle life warranty, three times the industry standard).Exponent's energy stack solves the extreme heat and lithium plating, two long-standing problems that have slowed down rapid charging on LFP cells.
Exponent leverages its Virtual Cell Model, Battery Management System, and Dynamic Charging Algorithms to actively recognise lithium crowding in real time and assure quick charging without major deterioration. This prevents considerable cell damage caused by lithium plating during charging. After 3000 charging cycles of 15 charging, independent testing by TUV India found just 13% deterioration.
Exponent uses a cutting-edge HVAC system that is "off-boarded" from the car to the e^pump to control the significant heat created during 15-minute quick charging. Each Li-ion cell in the e^pack is cooled by this system, which circulates chilled water through the e^plug. This system prevents the temperature from rising beyond 35°C regardless of the outside temperature. This strategy guarantees that Exponent-powered EVs will continue to be lightweight and inexpensive.
Exponent Energy's CEO and co-founder, Arun Vinayak, emphasised how their two-sided quick charging method extends EV battery life by three times and reduces cost by 30% compared to standard EVs. By 2025, Exponent wants to increase its operations in five additional cities, deploy 1,000 e^pumps, and power 25,000 electric vehicles.
He said, “Our off-board thermal management technology is proof that Exponent believes in creating the energy of the future by fusing cutting-edge engineering with practical economics.”
“Consumers require EVs to charge more quickly, last longer, and cost less for everyone to switch to electric vehicles. Our unique two-sided method of 15-minute quick EV charging extends EV battery life by three times and reduces cost by thirty per cent. We are eager to grow this throughout India, beginning with Delhi-NCR, Mumbai, Hyderabad, Chennai, and Ahmedabad,” he further added.
Exponent has conducted over 25,000 quick charging sessions over the past three months, and 200+ EVs using its technology have travelled over 10,000 miles on Bengaluru's roadways. Higher energy flow is made possible by the company's 15-minute quick charging, which enables them to create a lucrative and expandable EV charging network.
Exponent and Altigreen collaborated to create the ne EV Tez, the first electric vehicle to use the company's technology, last year. The startup's long-term goals include expanding its market share in the
