Along with the ever-growing number of electric vehicles on the market and pressure from governments to reduce vehicle emissions to zero latest by 2050, there is a strong need for more efficient charging solutions.

 

As various consumer studies show, the acceptance of electro-mobility very much depends on the availability and duration of the charging process, high-power DC charging stations are the answer to these market requirements.

 

Already today, a typical EV can charge about 80% of its battery capacity in less than 50 minutes. This is not comparable to refueling a conventional car with internal combustion engine.

 

CastNX brings the energy-efficient AC to DC fast charging module as a building block of charging station.

 

We are developing 25kW module (AC to DC) for application in EV charging as well as for electrolyzer’s for generating green Hydrogen.

Typically, a high-power DC charger converts an incoming three-phase AC voltage into the DC voltage required by the battery or system.

 

A data transmission channel is required to exchange information about the system voltage and the battery’s state of charge etc.

 

The three primary concerns in DC fast charger architecture are minimizing cooling efforts, providing high power density and reducing the overall size and cost of the system.

 

The targeted High power density requires forced air cooling/ liquid coiling and higher switching frequency of the order of 100 kHz.
