789 Wh/kg

(as per total device weight)

Very high energy density in the storage area

EV range increased by 5 to 6 times at similar weight.

This performance is applicable to all systems with E-Technology on board incl. cordless tools, household appliances, etc…

Opens new large storage system (high) capabilities at reasonable weight, for road, rail, sea & air transport, buildings, energy production & grid management, industrial, military, and strategic applications

Comparable to super-capacitors

Both input and output area

Allows for continuous fast electric charging: 50-100 times faster than a battery of equal weight

High power over total period of charge, (i.e. no careful end phase needed, as batteries require)

An innovative ultra-fast charging solution (IUFCS) is possible and is ideal for EVs and globally the transportation sector, without destabilizing the electricity network by high power demands (additional information reserved)

The high output allows fast acceleration for EV’s, aircraft take-off, high power release for demands as start-up of heavy machinery or at a different scale for domestic appliances (water heating, ovens, washing machines…)

Yield of about 95% +/- 2%


Marginal heat generated during charging or discharging

(due essentially to the electronics)rage area

Nearly no energy wasted, compared to couple “battery + charger”.

Battery performance depends heavily on temperature, conditions of use and life cycle.

Battery loss-rate leaves but 80% to 50% available.

Battery L.S.S.S.* incremental storage cost per kWh is between 10 and 15 times higher than the E-Technology storage cost and penalizes the end user price to exceed economic viability. The LSSS E-Technology solution is cost effective and can mitigate profit erosion where production volumes>demand.

*L.S.S.S. Large Scale Storage Systems

Capacity unchanged


Performance drop of only 1-2% at -20C°

All E-Technology on board devices work all year round consistently (compared to the performance dive for battery driven EV’s in winter). E-Technology requires no cooling.

Sustainable, environment friendly, cost effective

Mass production will reduce unit cost as no raw material scarcity at play.

Current mining of costly, scarce & dangerous raw materials could cease.

Recyclability is easy vs batteries

Storage uses metastable material once loaded

Release of energy on command by servo system loop

Safer than petrol, gas or hydrogen powered vehicles, or other transport/equipment used

Safer than batteries (no explosion, fire, or dangerous heat emission)

No hysteresis phenomena


No degradation of capacity nor yield after a 1300+ charge & discharge cycles test

Long depreciation period
Reduced full lifetime cost in all application fields: electricity production & distribution, domestic, transport, industrial & strategic

End Of Life (EOL) of storage device is not the limiting factor for electrical devices

High operating stability during discharge


No specific voltage required


Behaves like a generator set which can be charged using 2 ways depending on the amount of energy and the load speed required

Operate in input and output under different charge/discharge voltages without being trapped in Redox potential

Household appliances and domestic power could move to 48V DC (more safety) & elimination of transformers/chargers

The E-Technology home unit is equipped to deal with a grid power failure to provide back-up of choice.

Two very different charging options:

– Fast electrical charging
– Innovative Ultra-Fast Charging Solution
without affecting grid stability by excessive power demands (additional information reserved)

Possibility at any moment to set output different from input voltage

Fast electrical charging: ideal for electric cordless tools, cordless household appliances, small electric devices

Innovative Ultra-Fast Charging Solution (IUFCS): Ideal for transport (land, sea, air, space) (additional information reserved)
No need for heavy landlines to connect charging stations along road network
Charge and discharge simultaneously

Charge can be performed at higher voltage (for rapidity), whilst discharging at low voltage if desired

Area dedicated to storage is relatively small compared to input/output elements including electronics or, vs total size

The storage volume can be adapted to need, whilst input and output modules can remain constant in size.

Increase of storage area (weight/volume) requires low incremental cost, and benefits price per kWh of storage and improves energy density.
