Reinventing Fast Charging
Ultra-fast, low-current pulse technology charges lithium-ion batteries in minutes with minimal heat
Low Current
We charge differently. Instead of pushing extreme currents (4C and higher), PulseCharge uses high-voltage short pulses with low current. This unique mode activates natural lithium-ion diffusion, so part of the charge comes from inside the cell itself — without overheating or stress.
Cooler Operation
Minimal heat, maximum efficiency. Our pulse–pause control keeps cells stable with almost no heat build-up. Even during full charging, temperature rise stays around +11°C, compared to massive heating in conventional fast charging that requires complex cooling systems.
Longer battery life
Fast charging without degradation. Because most of the charge is delivered through internal diffusion rather than brute current, cells remain healthier. Tests showed only –2.8% capacity loss after 350 cycles, versus up to –23% with standard fast-charging methods.
Why Conventional Fast Charging Isn’t Enough
Current solutions rely on brute force current, causing heat, inefficiency, and limited results.
- 80% plateauConventional charging races to 80%, then slows dramatically. Users never get a true full charge in record time.
- Heat & stressHigh current creates excess heat, accelerates cell aging, and forces bulky, expensive cooling systems.
- Still slow in practiceEven the best public fast charging takes ~25 minutes for only 80% — far from the 5-minute refueling experience drivers expect.
Our Technology
PulseCharge delivers energy through ultra-short high-voltage pulses at low current. Between pulses, the cell keeps charging from within thanks to natural lithium-ion diffusion.

How it Works
The science behind ultra-fast low-current charging.
During each impulse, the cell receives a precisely dosed burst of energy at low current but high voltage. The inter-electrode distance in a Li-ion cell (~10 μm) creates an intense electric field that ionizes the cathode surface. In the pause, lithium ions and electrons diffuse from cathode to anode, continuing to charge the cell from within. This ambipolar diffusion means part of the charge is delivered internally, without external current flow — reducing stress on the battery. The higher the applied voltage peak and the shorter the impulse, the greater the contribution from diffusion.
Conventional fast charging pushes 4C or higher currents through the cell, generating significant heat (I²R losses) and accelerating degradation. PulseCharge, instead, operates at much lower current (e.g., 2.44 A vs 6.7 A for the same Samsung 18650 cell) while still achieving ultra-fast charging. Because Joule heating is proportional to the square of the current, lowering current dramatically reduces thermal stress. At the same time, our high-voltage short pulses activate internal diffusion, so the cell keeps charging even in the absence of external current. This approach prevents lithium plating, structural damage, and premature capacity loss.
The PulseCharge driver repeats the pulse–pause cycle hundreds of times per second. Pulse width, frequency, and capacitor parameters are dynamically tuned to match the specific Li-ion chemistry and battery format. By adjusting these variables, we maximize diffusion contribution while keeping thermal rise under control. This high-frequency operation delivers consistent performance across different battery types, from consumer cells to EV packs. In lab tests, this has enabled charging 3–10× faster than standard CC/CV methods, without compromising safety.
Even under full ultra-fast charging, the temperature rise of the tested cell stayed around +11 °C. By comparison, conventional fast charging requires liquid cooling or massive heat sinks to manage the thermal load. Because our method relies on diffusion and low-current pulses, heat generation is minimal, making cooling systems redundant. This not only reduces complexity and cost, but also improves overall charging efficiency. Cooler operation directly translates to longer battery life and safer high-power applications.
Conventional fast charging must taper down after ~80% SOC to avoid overheating and structural damage, which is why “80% in 25 minutes” is a common claim. PulseCharge avoids this limitation: internal diffusion allows the cell to continue charging safely to 100% capacity. Because most of the charge comes from within, the battery experiences far less stress. Long-term testing shows only –2.8% capacity fade after 350 ultra-fast charge/discharge cycles, compared to –23% under standard CC/CV conditions. This means drivers and device users get both ultra-fast charging and a much longer battery lifespan.
We tested a standard Samsung 18650 Li-ion cell (1.5 Ah, 3.7 V) under the PulseCharge regime.
Delivered from source: ~0.55 Ah; extracted on discharge: 1.5 Ah
This means 63% of the total charge came from internal diffusion, not external current. The energy balance was 6.04 Wh in vs 5.55 Wh out — fully consistent with the laws of physics. These results validate PulseCharge as a fundamentally different and more efficient way to achieve ultra-fast charging.
- Average voltage applied: ~11 V
- Average current: 2.44 A (vs 6.7 A in conventional fast charge)
- Charge time: 13 min 30 sec (2.6 V → 4.3 V, 0–100%)
- Temperature rise: +12 °C only

Recent Experimental Results and Validation Milestones
PulseCharge has already moved beyond proof‑of‑principle into independently validated hardware and scaled prototypes. A 100 W system was validated at Bar‑Ilan University, and we are now testing a next‑generation architecture around 1 kW on higher‑capacity cells.
In independent tests, commercial 18650 cells were charged in approximately 13–15 minutes, delivering full nominal capacity with only about a 12°C temperature rise and overlapping discharge curves. Scaling experiments on LiFePO₄ 10 Ah and 20 Ah batteries have demonstrated ultra‑fast charge cycles where diffusion‑driven internal processes contribute the majority of the delivered capacity, confirming that the PulseCharge regime is fundamentally different from conventional current‑based fast charging.
Our internal endurance testing has shown less than 2% capacity loss after 250 ultra‑fast charge–discharge cycles and roughly 2–2.5% loss at around 350 cycles, compared with significantly higher degradation in comparable cells under similar conditions. While we classify these long‑cycle results as internal lab data, they support a strong working hypothesis that PulseCharge can deliver not only faster and cooler charging, but also a lifetime advantage at scale.
On the technology roadmap, we are extending the platform to a 5 kW class system for higher‑energy applications, including 250 Ah batteries for e‑mobility, industrial charging and battery energy storage systems. In parallel, we are expanding our IP portfolio, pursuing international patent coverage and actively engaging with design partners in Europe and Israel to launch the first pilot projects and reference use cases in selected verticals.

FAQ
Frequently Asked Questions about PulseCharge Technology
PulseCharge is an ultra‑fast charging architecture for standard lithium‑ion batteries that delivers a full charge at a low average current, instead of simply pushing more current through the cell. We use short high‑voltage pulses that trigger an additional internal charge‑transfer mechanism inside the battery, which we describe as ambipolar diffusion. In practice, part of the charge is delivered directly from the source during the pulse, and part comes from internal diffusion‑driven processes in the pause after the pulse. This allows us to sustain very fast charging while keeping thermal stress and degradation significantly lower than with conventional current‑based fast charging.
We are well beyond a theoretical concept: PulseCharge has working laboratory systems and independently validated prototypes, not just simulations. The first public validation was carried out on a 100 W prototype at Bar‑Ilan University, confirming the effect and basic performance. Today we are testing a next‑generation architecture around 1 kW on higher‑capacity cells (10 Ah and 20 Ah) and preparing the next engineering version for OEM and embedded scenarios.
Yes. From day one we built PulseCharge around off‑the‑shelf lithium‑ion cells, not custom cell chemistries. Independent tests started with commercial Samsung INR18650‑15M 1.5 Ah cells and have since been expanded to typical cylindrical, prismatic and pouch formats. We have already demonstrated results on LiFePO₄ 3.2 V / 10 Ah and 20 Ah batteries, showing that the approach scales to higher‑capacity cells without requiring redesign of the chemistry.
In independent tests at Bar‑Ilan University, commercial 18650 cells were charged in approximately 13–15 minutes while still delivering their full nominal capacity of 1.5 Ah on discharge. The temperature rise during these cycles was about 12°C, and the discharge curves remained stable and overlapping, indicating no observable damage. In scaling tests on LiFePO₄ 10 Ah cells, we achieved a 12.5–13 minute charge, where only about 1.6 Ah came directly from the source and 8.49 Ah were delivered by internal diffusion‑driven processes; for 20 Ah cells, 1.54 Ah came from the source and 18.46 Ah from internal diffusion. These numbers highlight that PulseCharge operates in a fundamentally different regime than traditional charge‑transfer logic.
Using an industry reference profile from StoreDot as a benchmark, PulseCharge maintains a high charging rate over a much larger part of the state‑of‑charge curve. Where conventional fast‑charging solutions show a pronounced drop in power around 70–80% SoC, PulseCharge keeps a more stable power profile all the way up to 100% without the typical “cliff” at high SoC. This behavior is achieved at a lower average current and with a moderate thermal load, which is central to our differentiation.
At Bar‑Ilan University, a series of ultra‑fast charging cycles showed no observable damage and preserved normal battery operation, validating that we are not trading lifetime for speed at this stage. Internally, we have run endurance tests over 250 ultra‑fast charge–discharge cycles with less than 2% capacity loss, and around 2–2.5% loss at 350 cycles, while comparable Samsung cells in a similar regime show residual capacity of roughly 67%. We clearly label these long‑cycle results as internal laboratory data, and one of our next priorities is to expand this dataset across more chemistries, form factors and cycle counts together with independent labs.
Yes. Independent validation was conducted at Bar‑Ilan University under the supervision of Prof. Doron Aurbach, a leading expert in battery electrochemistry. The tests confirmed fast charging times, full nominal capacity after charge, stable discharge profiles and no visible damage to the cells over the tested cycles. The technology received a positive scientific assessment and a recommendation to continue R&D, which is a key credibility element for us as a deep‑tech company.
We have filed a US provisional patent application that covers the waveform generation, algorithmic control of the charging regime, module architecture and the high‑voltage pulse‑based energy transfer principle. In legal terms, we protect the practical rule set and operating mode that enable ultra‑fast charging of lithium‑ion batteries, rather than the abstract scientific discovery. The next steps include leveraging the granted patent documentation and expanding protection via PCT and additional key jurisdictions.
Our first customer is not the mass consumer, but a design partner that already ships battery‑based products and for whom charging time, thermal behavior and cooling complexity are real business constraints. Typical partners include OEMs, system integrators, embedded battery‑system vendors, BESS players, e‑mobility companies and industrial or robotics manufacturers. Depending on whether the lead investor is a financial VC or a strategic, we will either prioritize generic low‑ to mid‑power products (smartphones, mobile devices, power tools, embedded electronics) or co‑develop solutions for specific verticals such as large‑scale BESS and heavy‑duty applications.
