Here is verbatim quote from announcement on BRUSA website:
With the NLG664 BRUSA has set an milestone in e-mobility. The on board fast charger NLG664 is now available with 45-65 Hz input frequency and enhanced single phase current capability of 30 A. This provides a great flexibility for the worldwide use of our NLG664 on-board-charger. Thanks to its performance upgrade the charger NLG664 can also be operated in countries with 60Hz mains frequency. The NLG664 is the world’s first charger that allows the charging of a typical EV-battery in less than one hour from standard 3-phase AC grid and gives the additional option to charge with up to 7 kW from an appropriate single phase AC outlet.
