The formula for calculating it is known as Peukert's equation, and the important number, unique to each battery type, that is put into the equation in order to perform the calculation is known as Peukert's exponent. Thus the effect is now known as Peukert's effect. This effect had been known for many years but it was Peukert who first devised a formula that showed numerically how discharging at higher rates actually removes more power from the battery than a simple calculation would show it to do. However, battery capacity decreases as the rate of discharge increases.
for a given capacity C and a discharge current I, the time will be You may think that calculating how long a battery will last at a given rate of discharge is as simple as amp-hours: e.g. I'm not an electrician, so please pardon me for any mistakes.īattery capacity is a measure (typically in Amp-hr) of the charge stored by a battery. Some of the milestones include 5 back-to-back rapid charge cycles on a vehicle for a 400-km run in a single day and clocking over 10,000 km of city-driving in a 40-day period, it added.Everything below was created after spending several hours searching and reading the internet. After 6 months of joint development and on-road testing with Altigreen, the solution has reached maturity to hit the market. This is achieved by the e^pump delivering 600A of current to the e^pack (15x industry standard) while managing individual cell characteristics including thermals to ensure safety, long battery life, and performance consistency even at 50 degrees Celsius.Īccording to the startup, it has collected data for thousands of charging cycles (equivalent to many lakhs of kms) in 18 months of e^pack’s evolution.
The vehicle delivers a city drive range of 80-85 kms and charges up in 15 minutes at Exponent’s e^pump network. The Exponent Enabled Altigreen neEV HD has an 8.19 kWh e^pack - a proprietary battery by Exponent. “By being cell agnostic, we can leverage the existing manufacturing ecosystem that produces LFP and NMC cells extensively,” Arun further added. Our e^pack & e^pump make this possible with 15-minute rapid charging and 3000 cycle life warranty (a new industry standard).” The same will be used to offer the benefits of Exponent’s 15-minute rapid charging across India.Įlaborating on the partnership, Arun Vinayak, Co-founder & CEO, Exponent Energy said, “For all of India to go electric, EVs need to charge faster and last longer. With a fresh round of INR 300 Cr investment led by Sixth Sense Ventures, Reliance New Energy, Xponentia Capital, and others, Altigreen is aggressively ramping up its R&D and production capabilities while developing a robust pan-India distribution network to offer the cleanest last-mile transportation. Speaking about the first-ever 15-minute rapid charging deployment for CVs, Amitabh Saran, Founder & CEO, Altigreen Propulsion Labs, said, “This partnership with Exponent will now make us the fastest charging 3-wheeler that offers flexibility and freedom to our customers, and helps them earn even more.” They unveiled the fastest charging electric 3-wheeler that rapid charges from 0-100% battery capacity within 15 minutes. New Delhi: Exponent Energy, a start-up simplifying energy for EVs, on Wednesday entered into a partnership with Altigreen Propulsion Labs, an electric commercial vehicle manufacturer, to make rapid charging for eCVs on Indian roads.
