Chademo
there has been a wide variety of chademo dc fast changing controllers and software over the years. here you will find links and bits of info on a Varity of these projects. many are legacy projects now, as things like the zombiverter have chademo fast charging integrated in.
legacy evbmw chademo boards:
https://github.com/damienmaguire/Chademo-Fast-Charge-Controller
there are a variety of versions of theses boards, different processors, connectors and software.
gen 1 and 2 boards had localized current and voltage sensing, where the ISA versions uses the ISA shunt.
isa based boards: https://github.com/damienmaguire/Chademo-Fast-Charge-Controller/tree/master/ISA_CAN_Version
both the sam and stm32 boards with the molex headers share the same pinout.
ISA chademo board v1/ v2 pinout:
https://openinverter.org/forum/download/file.php?id=5542
The controller requires two Molex plugs and pins. 20 Way plug p/n :33472-2001 12 Way plug p/n:33472-1236 Pin p/n:33012-2002 20 way plug
pinout : 1 - Ground – Chademo Pin 1
2 - Proximity– Chademo Pin 7
3 - Not used
4 - Out2– Chademo Pin 4
5 - IN1– Chademo Pin 10
6 - IN2– Chademo Pin 2
7 - Not used
8 - Not used
9 - FC CAN L– Chademo Pin 9
10 - FC CAN H– Chademo Pin 8
11 - Not used
12 - Not used

20 - Not used
12 way plug pinout (To ISA Shunt / Car) :
1 - Ground
2 - 12v Permanent supply
3 - Not used
4 - CAN2 High – ISA Shunt CAN High
5 - CAN2 Low - ISA Shunt CAN Low
6 - GND
7 - Out3 / HV System Activate request – Low side switch
8 - FC HV Contactor Coil Pos
9 - FC HV Contactor Coil Neg
10 - Not used
11 - Not used
12 - Not use
to bench test the board, apply 12v power and gnd, then pull the proximity input to gnd. the on board relay should switch and you should see a led light on.
final stm32 uses a 35pin ampseal connector:
a few of the legacy stm32 boards have a hardware issue:
some boards came fitted with a bsp75n low side driver. this is the wrong part! in the schematic its marked to be ncv8402. The difference is the bsp75n has the source on the tab and the ncv8402 has the drain on the tab.
isa shunt
the isa shunt is used for voltage and current measurements
the shunt must be programed over can bus to work:
