i have a project being designed for an off grid solar ev charger,
the hardware being used is a selectronics sp pro SPLC1202 so needing to create a 120 volt(depleted 100 volt) -(full charged 170 volt) battery bank(300 kwh)
but because i need to drain 350 amp per cell every hour(14k amps) out of 700ah cells, or 44.8kw every hour per bank of 40 cells with a 10% buffer. but need to have bluetooth and rs485 and can bus options as i have to parallel 7 banks into 1 to make a 313.6 kwh pack
so suggestion on how to do the 40s BMS and also the high amperage because between all 7 packs need to get 21kw off each 40 cells bms pack.
