Battery Maker Exponent Claims Lowest Degradation After 3000 Quick Charging Cycles

Exponent Energy, an energy-tech startup that claims to have unlocked a 0 to 100% charge in 15 minutes for EVs, has announced the successful completion of 3000 cycle testing in collaboration with renowned German testing agency, TUV India (TUV Nord Group, Germany). The company says that the testing reports only 13% battery degradation even after 3,000 cycles of 15-minute rapid charging of Exponent’s proprietary battery pack – the e^pack. This achievement marks a significant milestone in addressing the challenges associated with battery health degradation and rapid charging.

Traditionally, Li-ion cells experience a decline in health (charge capacity) as they undergo cycles of full charge and discharge (1 cycle = 1 full charge + 1 full discharge) and rapid charging exacerbates this issue. However, Exponent Energy says that its proprietary energy stack, which enables a 15-minute full cArun harge, has demonstrated exceptional performance in maintaining battery health of 87% of its health in 3,000 cycles.

Commenting on this achievement, Arun Vinayak, CEO and Co-founder, Exponent Energy said, “Delivering 15-minute rapid charging whilst maintaining remarkable battery health is a game changing proposition. This achievement makes us the first player in the industry to witness only 13% degradation over 3,000 testing cycles on LFP-based battery packs as compared to the industry average of 30% degradation in 1500 cycles with slow charging. TUV India’s (TUV Nord Group, Germany) report will undoubtedly enhance trust in our technology with all key stakeholders in the EV ecosystem”

Earlier this year, Exponent had launched 5-year financing with 30% lower EMI in partnership with Alt Mobility. Combined with successful completion of 3000 cycle testing, Exponent aims to on-board many more financing partners to ensure that EVs powered by exponent continue to be the most advanced & affordable EVs for customers to purchase.

Exponent’s achievement, if it holds up to market conditions will be a significant step ahead in a market where even as fast charging is still not available at scale, when it does, it does need to address the issue of faster degradation from repeated charging.
