Quick Start Guide V2 for NLG6xx chargers

The NLG6xx chargers depend on some external (analog/digital) signals, as well as CAN control commands,
in order to perform charging. The following leaflet explains how to connect and control the charger in default
configuration for basic operation, as an introduction how to use the charger and how to read the manual.
DANGER !
Make sure to study the manual thoroughly before connecting the charger!
Follow all safety rules! Failure to do so may result in severe injuries or even death,
due to the lethal danger involved with the electric energy on input and output side
of the charger!
1.
DO NOT POWER UP THE SYSTEM BEFORE ALL CONNECTIONS ARE ESTABLISHED !
2.
Connect all required control signals:
a.
LV plug “vehicle” 12-pole CodeA
- Pin1: “Kl30”, +12V cont supply, +12V car battery
- Pin3: “Kl30C”, connect to Pin1
- Pin7: “Kl31”, -12V, car chassis or negative terminal of 12V battery
- Pin2 and Pin8: “EV_CAN_H” and “EV_CAN_L”, CAN bus to control the charger.
Make sure CAN sender has the same ground potential as the charger.
b. LV plug “charging socket” 12-pole CodeB
- Pin2: “PROX_D”, Proximity detection resistor (according to IEC 61851 / SAE J1772)
- Pin11: “CTL_PIL”, Control Pilot signal (according to IEC 61851 / SAE J1772)
- Pin7: “TEMP_Con”, PT1000 temperature sensor signal
3.
Connect HV DC side of the charger to positive and negative terminal of the HV battery; make sure to
employ appropriate precharge circuitry.
4.
Connect AC side of the charger to phases 1/2/3, Neutral and Protective Earth of the AC outlet.
5.
Power up AC input and LV (12V) DC input of the charger

6.
Send CAN message “NLG_DEM_LIM” (0x711) every 100ms to the charger.
In the table below, the meaning is: black = required; grey = not required for basic operation.
NLG_C_ClrError
Clear error latch
cycle 0-1-0 to clear all resettable errors
NLG_C_UnlockConRq
Unlock connector
request
The charge coupler can be locked by motorized mechanical latch
(in car inlet). Once proximity signal is detected, a lock signal is
put to pins 5+10 of connector codeB. This signa unlocks it.
NLG_C_VentiRq
Control pilot
ventilation request
Request Ventilation from charging station (force State D on
control pilot signal)
NLG_DcHvVoltLimMax
Maximum HV voltage
Currently desired (maximum) charging voltage to the battery
NLG_StateDem
NLG state (see state
machine)
0: StandBy
1: Charge
NLG_DcHvCurrLimMax
Maximum HV current
Currently desired (maximum) charging current to the battery
NLG_LedDem
Charge LED demand
Output a specific LED pattern at pins 3,4,9 .
NLG_AcCurrLimMax
Maximum AC current
Currently desired (maximum) AC input current
NLG_C_EnPhaseShift
AC power factor
request
Use the NLG6 to compensate reactive power on grid
(not used / not implemented yet)
NLG_AcPhaseShift
AC phase shift
Use the NLG6 to compensate reactive power on grid
(not used / not implemented yet)
Note: All required (black) data in the table above must have appropriate values in order for the charger to
work correctly. Grey ones are kind of “don’t care” for basic operation. Please refer to the separate CAN
documentation (in .html or .dbc format) for details on data representation like scaling, offset etc.
Example: We want to instruct the charger to output a maximum of 10Amps to the battery up to a voltage of
400VDC, while allowing a max current of 20A per AC-phase.
DcHvVoltLimMax: 400V x10(scale)

4000(scaled) + 0(offset)

0xFA0
DcHvCurrLimMax: 10A x 10(scale)

100(scaled) + 1024(offset)

0x464
AcCurrLimMax:

200(scale) + 1024(offset)

0x4C8
20A x 10(scale)
Taking factors, offsets and bit positions of the required signals into account, this msg in hex looks like:
711 8 0F A0 24 64 04 C8 00 00
It is strongly recommended (though not an absolute requirement) that the feedback messages from the
charger in the table below are evaluated and appropriate reaction is taken when required.
NLG_ACT_ERR
0x799
NLG_ACT_INT
0x709
NLG_ACT_LIM
0x728
NLG_ACT_AC
0x729
More information about connections, signals etc is found in the corresponding manual and the CAN matrix.
