Nissan Leaf PDM teardown

Post by johu »

I took the Nissan Leaf PDM apart:


So in modern chargers current passes over EMC filters, rectifier, PFC boost stage, chopper stage, high frequency transformer, another rectifier and another EMC filter. No wonder charging losses are rather high and you need liquid cooling.

Are parts from this available? I have a PDM with a fried pfc/chopper board (I think) that I wouldn't mind using sometime in the future. Can't promise any open source development on it but I'll at least document my improvisations next time.

Yes I'd give away all of the charger parts, let me know your address and just send 15€ for tracked shipping

Cool. It looks more simpler than the huge housing would let one think...

Hi Johannes,
I too did not use the Charger from the EM57 Stack, just the inverter and motor. But on my '70 MGB project i will need a DC-DC charger sufficient to power the MGs lights etc. Can the DC-DC Charger board be rigged to supply 13.8VDC to run the accessories and keep the battery charged while turned on and supplying it the leaf battery voltage?
sorry, I can't figure out how to show the board jpg I have in this post

Hey Guys, hope everyone are all good. Still working on the project and making some progress.

At the moment, I am working on the AC charging, getting the specific CAN message that is required in order to activate the charging. I’m using the ZombieVerter VCU with 2.05.A, the original type2 connection and AC cable to the wall. I’ve tested to set up and was able to replay kind messages which works, and I am able to get the VCU into charge mode, however, I cannot seem to come on the power. My Pwrspnt is set to 1500 but unfortunately makes no change.

I’ve done some reverse engineering on the CAN messages that I have been replaying and found that, the following tents to get the charging going, however, what is sent from the VCU is slightly different
0x1f2 : 0x30 0x85 0x20 0x00 0x00 0×82 0x01 0x0F
0x1f2 : 0x30 0×85 0x20 0x00 0x00 0×82 0x03 0x01
0x1f2 : 0x30 0×85 0x20 0x00 0x00 0×82 0×02 0x00
0x1f2 : 0x30 0×85 0x20 0x00 0x00 0×82 0×00 0x0E
0х50B : 0x00 0x00 0x00 0xCO 0x00 0x00

I’m just wondering whether the coding to the VC you got corrupted somehow in the process of uploading or am I missing something?
