6.4 Basic function
The NLG6 transforms 1- or 3-phase alternating current into direct current and provides galvanic isolation
between the public AC grid and the HVDC system of the electric vehicle. This allows for charging the battery
on one hand, and on the other hand ensures the safety of both grids.
Battery charging is controlled by CAN, i.e. NLG6 limits current and voltage to the values received by CAN. If
for a certain time (ca. 0.5s) no such signals are received, the unit interrupts the charge in order to protect the
battery.
NLG6 contains an interface for IEC-61851 / SAE-J1772 signals, i.e. the respective safety signals and
protocols like Control Pilot and Proximity are served according to the standards. Additionally, there are
protection measures integrated in the unit (temperature detection and derating, fuses) to protect the unit from
overload and to interrupt the power flow in case of potentially dangerous situations and fault patterns.
