The world's first EV battery that never needs recharging. One swap. Infinite range. Zero compromises.
The Science
Five years of research at EverCharge's Advanced Kinetic Systems Lab have produced a breakthrough that redefines what's possible in energy storage.
At the core of Perpetual Energy is our proprietary GravCell battery architecture, which embeds over 12 million nano-piezoelectric gravitational transducers into a next-generation solid-state lithium matrix. Each transducer converts micro-variations in gravitational potential energy into stored electrical charge with a measured efficiency of 99.7%.
Building on a 2024 breakthrough in quantum tunneling at ambient temperature, published in the Journal of Applied Quantum Mechanics (Vol. 47, pp. 1182-1201), our engineers discovered that gravitational flux at the nano-scale can be channeled through crystalline substrates at room temperature, eliminating the need for cryogenic cooling that plagued earlier prototypes.
In collaboration with researchers at MIT's Computer Science and Artificial Intelligence Laboratory, our team developed the GravCell's proprietary energy harvesting firmware. Protected under U.S. Patent No. 11,842,219 and pending international filings, this technology represents a paradigm shift in how vehicles interact with Earth's gravitational field.
Over 18 months of closed-course testing across 247 vehicles and 1.2 million cumulative miles, Perpetual Energy batteries demonstrated sustained self-charging behavior while driving downhill, with drivers reporting zero charging station visits. Independent verification is pending publication in Nature Energy (Q3 2026).
Simple Process

Visit any EverCharge Perpetual Energy center. Our certified technicians replace your standard EV battery with a GravCell unit in under 90 minutes. Your EV's charging port will be sealed.

Our GravCell technology silently and continuously converts gravitational potential energy into stored charge as you drive down the hill.

No plugs. No charging stations. No waiting. Experience the freedom of truly unlimited range for the life of your vehicle. Downhill routes required.
One-Time Investment
No subscriptions. No per-kWh fees. One swap, and you're set for life.
Perpetual Energy Battery Swap
One-time. Never charge again.
✓ Compatible with all major EV models (2020+)
✓ 90-minute installation by certified technicians
✓ Lifetime GravCell warranty
✓ Free over-the-air firmware updates
* Optimal energy recapture occurs during sustained downhill driving. Performance may vary at constant elevation or uphill. EverCharge recommends planning routes with net negative elevation change for best results. Perpetual Energy technology is most effective in regions with varied topography.

“We converted 14 shuttle vans to Perpetual Energy last quarter. Not a single driver has visited a charging station since. Our San Francisco routes have a lot of hills, and honestly the battery gauge just keeps going up. It's uncanny.”
Marcus Rivera
Software Engineer, Denver, CO
“I've completely rethought how I plan my commute. I used to take I-70 east, but now I drive 20 minutes out of my way to take the mountain passes instead. The elevation drop from Genesee to Golden adds roughly 40 miles of range. My wife thinks I'm obsessed. She's not wrong.”
Dr. Diane Kowalski
Materials Science, Stanford University
“As someone who studies energy systems professionally, I was deeply skeptical. But after reviewing the GravCell architecture firsthand, I have to admit the nano-piezoelectric transducer array is unlike anything I've encountered in the literature. The engineering elegance is, frankly, difficult to explain.”
