3.4 Safety installations / power limitations
3.4.1 Control Pilot acc. to SAEJ1772 and / or IEC61851
Control-Pilot (CP) is a standardised signal transmitted via an additional conductor in the charging plug. The
CP interface enables a bidirectional exchange of information between the charging station and electric
vehicle and is globally standardised. Thanks to this signal, the EVSE can provide the charger with
information on the permissible maximum current load of the mains socket and the available power capacity.
In case of the NLG6, this current can be max 32 A (= max. current limited by the charger). The charging
process is coordinated via this signal and appropriate grounding is ensured.
The Control Pilot is a safety measure that also increases the reliability of the charging process of an electric
vehicle. It is absolutely necessary if the charging current on the mains side exceeds 16 A.
3.4.2 Mains overvoltage protection
Overvoltage protection is integrated in the charger to provide permanent protection against overloading.
Mains overvoltage is detected by the quick sensor system and leads to immediate shut down of the charger.
Highly energetic overvoltage (e.g. due to lightning) is absorbed by protective elements.
Also on the output side, overvoltage protection is integrated. The quick sensor system detects overvoltage
on the HV battery side (e.g. load drop or fluctuations) and the charger is immediately shut down.
3.4.3 Mains protection input current
On the charger, each phase (L1, L2, L3, N) is protected by a 40 A fuse in order to protect the device and
electric systems from damage due to overcurrent. If one of these fuses is blown, the charger must be
returned to BRUSA Elektronik AG! Do not open the device – no user serviceable parts inside.
3.4.4 Overcurrent protection
Overcurrent protection is integrated in the charger to avoid overload damage. The quick sensor system
detects any overcurrent and either reduces the current by regulation or shuts the charger down.
INSTRUCTION
We strongly recommended that you install a suitable overcurrent protection (fuse) close to the battery
between charger and battery, in order to protect the wires between charger and battery!
