Electric G wagen

Post by JSJFIN »

Hi,

Here is some information of my conversion project it now driveable and waiting for mot inspection.

Arduino due as main computer.
Motor Nissan leaf with can bus control.
Battery renault fluence 2011 (nissan bms)
Charger Tesla 11kw (two working modules)
Vacuum pump Audi Q5
Power steering Opel Zafira
Heating Tesla battery heater
Dashboard and some controls (heating, regen, mayby more in future) https://realdash.net/index.php and old tablet.

Below is some teaser pictures and more can be found here:

And some videos:

Hi, great conversion.
I would like to know what software you used to control/read the bms . I have a leaf pack and would
like to use it as it is , albeit in a different box ! I have a leaf motor with Johannes controller.
Any advice appreciated !

Ylipää - good to see some Finnish roads :)

So I have a question: are you using the power limits from Leaf BMS, or calculate your own?

In regen i just have manual control and some constants like if below zero C no regen at all. And output power is just linear tps -> can bus torque command to leaf inverter and it seem that leaf inverter is limiting power to about 80kW.

Edit:
It could be that inverter is getting power limit directly from BMS i have to put discharge limit to screen so i can watch what it shows.. i never even looked the value but one old log shows:

Soc 66%
DischargekW: 93

Awesome project and amazing to see the leaf motor operating well within its capabilities pushing the G Wagon at 80kph plus.

I’m also controlling the Leaf motor through CAN with a DUE, I have a quick question about regen. How are you implementing regen in your code? Would you be able to share this section of your code please? I’d love to be able to try this out on the Fig-Leaf.

Great project. I am about to go in a similar direction (G Wagen and Leaf).
