Pulse Charge Tech Ltd is an Israeli deep-tech startup developing a patented high-voltage pulsed charging technology that enables ultra-fast charging of lithium-ion batteries with minimal heat rise and no measurable degradation.

Unlike conventional CC-CV charging, which relies on high continuous current and causes overheating and accelerated battery wear, Pulse Charge uses very short high-voltage pulses (nanosecond–microsecond scale) separated by controlled pauses. This architecture allows a significant portion of the battery charge to be transferred through internal ambipolar diffusion during pulse pauses, reducing current-induced heating while maintaining high charging speed.

The technology has been experimentally validated on standard 18650 lithium-ion cells, achieving:

4–5× faster charging

Full 0–100% charge in ~15 minutes

Temperature rise of ~12°C

No degradation observed in laboratory tests

Independent validation was conducted in collaboration with Prof. Doron Aurbach’s laboratory at Bar-Ilan University, confirming the safety, repeatability, and technical feasibility of the Pulse Charge approach.

Pulse Charge is fully compatible with existing lithium-ion chemistries, requires no battery redesign and no special cooling, and is designed for scalable integration across multiple markets.

Primary applications include:

Electric vehicles and fast-charging infrastructure

Robotics and power tools

Consumer and industrial electronics

Energy storage systems (ESS)

Pulse Charge Tech is currently at the pre-seed stage, advancing from laboratory prototype to scalable hardware platforms and multi-cell systems.
