Do you plan to find the heat rejection limit and just set the max current there, or could you have the system charge faster to start and just reduce the current to stay under some temperature limit? In cold weather, like driving to Tahoe, it would be nice to be able to charge faster when the cooling system is more efficient.
Also, what is the rating on the Yazaki inlets that were installed? Are they rated for 200 amps? What about the HV cables between the inlet and the battery pack?
The relays are 800a rated, about 200a continuous.
Cables to the battery are 2 gauge, which likely can handle short term 200a (I honestly don't know right now). These can somewhat easily be made larger.
Inlet cables to the relays are the metric equivalent of 2 gauge. These cannot be made larger, therefore the single weakest link with the JdeMO hardware is this link.
After extensive testing, we will set the maximum amps at whatever is logical for the weakest link.
The battery temperature part is somewhat easy. If it gets warm, we reduce power. Nothing will change, except the maximum amps, plus we will add either one or two lines to the temp table:
10C to 45C cell temperature = 125a max
15C to 44C cell temperature = 150a max
17C to 43C cell temperature = 200a max
In addition, we will likely explore ways to manually run the cooling pump and air conditioning compressor at 38C.
