Exponent Energy, a Bengaluru-based energy-tech startup, claims to have tackled two major challenges (lithium plating and excessive heat) in the electric vehicle industry. They are using refrigerating water to keep the battery cell cool during the charging process.

There are still a number of issues preventing the widespread use of electric vehicles, despite the fact that demand for them is on the rise. “Charging time” comes out as a major problem among these. However, a Bengaluru-based startup thinks they have the answer to this issue. A rapid charging technique called Exponent Energy, a three-year-old firm, claims to fully charge any electric vehicle in just 15 minutes.

The time needed to charge an electric vehicle is the second top worry for owners after range anxiety. Fortunately, it appears that this issue has finally been resolved, and electric vehicles will soon be able to charge quickly, much like how smartphones can do so today. Let’s examine this rapid charging technology’s specifics and operation.

The three primary components being developed by Exponent Energy are the e-pack (battery pack), e-pump (charging station), and e-plug (charging connector). The business asserts that any electric vehicle, including a bus battery, can be fully charged using their e-pump, or charging station, in less than 15 minutes.

The secret to their breakthrough lies in their novel approach to battery cell cooling. The e-pack, which houses the battery cells, is kept cool using refrigerating water during the charging process. This innovative cooling mechanism not only ensures faster charging but also addresses the challenges posed by lithium plating and excessive heat.

When lithium ions in the battery pack accumulate on the anode rather than being absorbed during charging, a phenomenon known as lithium plating takes place. As a result, battery performance is decreased and potential long-term harm is created. On the other side, excessive heat is a common problem during fast charging and it might hasten battery deterioration. Exponent Energy’s technology reduces these problems by adeptly controlling temperature, leading to a more durable and secure battery.

Three key phases make up the charging process: pre-conditioning, fast charging, and cool-down. The battery is gradually warmed to the ideal temperature during pre-conditioning for effective charging. Delivering a high current to the battery cells during the fast charging phase enables quick recharging of the battery’s energy reserves. The cooling system keeps the battery’s temperature at a healthy level throughout this operation to avoid any negative impacts.

Modern power electronics and cooling technologies enable Exponent Energy’s charging stations to withstand large charging currents while maintaining the battery’s security and longevity. Advanced battery chemistry, charging algorithms, and effective cooling technologies come together to create an exhilarating future for owners of electric vehicles.

Exponent Energy’s rapid charging technology has the ability to completely alter not only the electric vehicle business but also how people view and utilize electric vehicles. Electric vehicles become more acceptable to a wider audience and considerably lessen range anxiety when they can be fully charged in just 15 minutes.

The development of rapid charging technology by Exponent Energy is a positive development for the future of electric cars. This creative idea promises to hasten the adoption of electric vehicles and usher in a cleaner, greener transportation future by addressing the issues related to charging time. The car industry is set to undergo a transformation as a result of this technology as it becomes more widely available and pervasive, opening the door for an environmentally friendly and sustainable transportation system.
