I just can't get the difference between these two Parameters despite reading the Wiki, could someone explain the difference as if I was an 8 year old please? To be specific, do I need to set both, do they both need to be the same? I am running a Tesla Model S Gen 2 onboard charger. Which I recon uses CAN to control the power modules.

idclim

• This parameter is mainly relevant for CAN operation. It is transmitted via CAN to let the vehicle know how much DC current the charger can deliver.

(Each charger module maxes out at about 15.5A so the maximum total charging current is 46.5A. Since the total power is also limited to 10 kW it depends on the output voltage as well. There is no need to be exact on this, the firmware will automatically limit the AC input current to each module to the hardware maximum.)

idcspnt Direct Current Setpoint? What's a setpoint?

• DC charge current limit.

• An additional limit to charge power.

• It is also mapped to the CAN bus so if you have a BMS that calculates a maximum charge current you can forward this to the charger.

It has to do with the CHAdeMO protocol.
idclim has absolutely now influence to charger operation, it only communicates to the car how much current the charger is able to deliver. So when not running CHAdeMO this parameter is irrelevant.

idcspnt sets the DC current that the combined 3 chargers should deliver.

thank you, I really like how you explained that, would it be ok for me to add that to the Wiki?

just playing around with a super basic charging diagram schematic for absolute newbs

Yes, please

Thanks a lot I was confused too.
