The world’s only AC characteristic
battery fast charging method
After years of research and development, our company has created a device for charging sealed, care-free batteries.
This research can serve as a basis for the development of technologies that allow the application of variable impedance oriented charging (proton exchange) in a wide range of locations.
Our charging equipment is suitable for both the AC charging we developed and the DC charging used today.

Test report
Patented on January 16, 2014. Hungarian Patent Office entitled “Procedure and/or switching arrangement for fast charging of batteries with bound electrolyte”. Registration number: 229590
Without 100% charging in a short period, the E-vehicle mass production will never take place.
The most beneficial effects are achieved by the AC type proton exchange fast charger system as follows
1. The conversion to chemical energy works on a different principle than DC (molecular drift) charging.
2. Batteries are charged by variable impedance oriented AC (proton exchange) charging.
3. The conversion of the electrical energy input during charging into chemical energy is achieved by an AC current with a DC voltage and a DC frequency.
4. using DFRA, PWM, Power Factory Control.
Number of fast charge cycles without quality degradation, with LiFePO4 battery
There are many statements about 30-minute DC fast charging. However, all of these statements omit a very important piece of data. Namely, how many fast charge (30 minute DC) cycles the battery packs can withstand.
The type of drive battery we use (LiFePO4) is less than half the price of many batteries in use today.

For bicycles, scooters, wheelchairs, etc., 220V mains supply is sufficient for fast charging
Comparison of ordinary DC charging and AC type quick charging
Ordinary DC
AC type
Charging time to 100% level:
At least 6-8 h
Charging time to 100% level:
SLA – 15 min ; NiCd, NiMH, LiFePO4 – 20 min
The higher charging current or pulse used to reduce the charging time puts a lot of strain on the battery structure. Significantly higher wear rate
The charging time is independent of the battery A/h value!
The superpositive alternating charging current, which is several orders of magnitude higher than the conventional one, does not damage the battery structure due to the effect described
High heat generation due to molecular drift, which increases oxidation and thus battery wear
The quantity of the plumb-sulfate doesn’t increase during the time of usage, and it can recombine by charging.
Battery wear and tear is increasing.
It definitely slows down the wear and tear of the batteries.
The number of charging cycles is limited. (data given by the manufacturer) It could decrease with the charging method if it uses a higher charging current than 3.5C
The charging cycle increases significantly compared to the factory data if AC charging is used continuously.
The amount of energy that can be taken out of the battery gradually decreases (A / h value).
The amount of energy that can be taken out from the battery does not decrease. (Increases initially).
The transfer of energy required for charging occurs continuously during the charging time, so in most cases the normal network is sufficient
The transfer of power for charging takes up to 20 minutes.
For higher A/h batteries, an industrial network is therefore required
