Exponent Power’s 15-Minute Speedy EV Charging
Exponent Power’s proprietary power stack to make EVs 30% extra inexpensive; Showcases patented ‘Water-Based mostly’ off-board thermal administration system that makes 15-minute fast charging an on-road actuality.
● EVs powered by Exponent have coated 10,00,000+ kms, accomplished 25,000+ fastcharging classes, and managed to scale back EV charging prices by 33%.
● Firm plans to broaden operations to 5 new cities by the top of FY ’24 and isconcentrating on to deploy 1,000 e^pumps and 25,000 EVs powered by Exponent, by 2025.
Exponent Power, an energy-tech startup unveiled the tech behind its 15-minute fast charging answer for the EV business. Exponent showcased its proprietary power stack – battery pack (e^pack), charging station (e^pump), and charging connector (e^plug) that collectively unlock a 15-minute fast cost and lengthy battery life (3000 cycle life guarantee, 3 occasions the business normal) – all completed on common LFP cells for the primary time in historical past.
Speedy charging kills vary nervousness and the necessity for costly, outsized battery packs. With this distinctive two-sided strategy, EVs powered by exponent will likely be 30% extra inexpensive, made potential by an optimized battery capability (30% smaller), and 5-year financing (powered by 3000 cycle life guarantee). Moreover, 15-minute fast charging reduces EV charging prices by 33%.
Exponent’s power stack addresses two key issues that, for many years, prevented fast charging on LFP cells – Lithium plating and Excessive warmth.
Tackling Lithium plating to stop vital cell degradation
When charging a cell, Li-ions move from the cathode to the anode and get absorbed. The quicker you cost, the extra ions move, resulting in crowding across the anode. If left unchecked, this crowding results in lithium plating, leading to vital cell degradation. Exponent solves this by a mix of their Battery Administration System (10 occasions extra correct than the business normal), Digital Cell Mannequin, and Dynamic Charging Algorithms. This enables them to proactively sense Lithium crowding in actual time and guarantee every cell is fast charged with out vital degradation.
This strategy was validated by an unbiased testing laboratory – TUV India (TUV Nord Group, Germany) that discovered solely 13% degradation after 3000 charging cycles of 15-minute fast charging.
Off-board thermal administration for fast charging in any ambient temperature
15-minute fast charging generates a ton of warmth. 256 occasions greater than the business common of 4-hour charging. If this warmth isn’t extracted, the battery pack would overheat and change off. Moreover, in India, the ambient temperature is 40°C or increased and Li-ioncells have a far decrease thermal candy spot of 25-35°C. To resolve this, we’d like superior HVAC methods, that are each cumbersome & costly. Moreover, this stage of warmth is generated solely when one quickly fees an EV and never driving it.
Subsequently, Exponent has constructed a complicated HVAC system that’s “off-boarded” from the car to its e^pump. Whereas charging, the e^pump transfers refrigerated water by the e^plug to chill each Li-ion cell within the e^pack. This ensures the e^pack’s temperature doesn’t exceed 35°C in any ambient temperature situation. Moreover, with the costly system “off-boarded”, EVs powered by Exponent are each inexpensive andlight-weight.
Arun Vinayak, CEO and Co-founder, Exponent Power mentioned, “At Exponent, we’re constructing the way forward for power that mixes cutting-edge engineering with real-world economics, and our off-board thermal administration system is a testomony to that perception. For everybody to go electrical, customers want EVs that cost quicker, last more and price lesser. Our distinctive two-sided strategy to 15-minute fast charging makes EVs final 3 occasions longer and price 30% lower than standard EVs. We’re excited to scale this throughout India beginning with Delhi-NCR, Mumbai, Hyderabad, Chennai and Ahmedabad!”
Within the final 3 months, Exponent has accomplished over 25,000 fast charging classes,coated over 10,00,000 kms with 200+ EVs powered by exponent on highway in Bengaluru.
Exponent’s 15-minute fast charging additionally unlocks increased power throughput enabling the firm to construct probably the most worthwhile and scalable EV charging community. Their e^pump in Mahadevapura, Bengaluru did a whooping 41 charging classes in a single day setting a brand new benchmark within the EV business.
Exponent Power trying to broaden its operations in 5 extra cities – Delhi NCR, Mumbai, Hyderabad, Chennai, and Ahmedabad by the top of FY ’24 and is concentrating on to deploy 1,000 e^pumps and 25,000 EVs powered by Exponent, by 2025.
Previously yr, Exponent partnered with Altigreen, ensuing within the profitable launch of the primary EV powered by Exponent – the neEV Tez. Wanting forward, Exponent goals to deepen their presence within the 3-wheeler cargo and passenger car market and likewise discover new car classes. The startup is backed by key buyers like Lightspeed India, YourNest VC, 3one4 Capital, AdvantEdge VC, Hero MotoCorp’s Chairman, and CEO, Dr. Pawan Munjal’s household workplace, Motherson Group, and has raised $18mn up to now.
