BMS for Batteriepack 100 cells in series - Batteriemanagementsystem It has to be a digital BMS 10 batteriemodules à 10 cells in series Values to measure: -Voltage of each cell in series -Current of the complete pack (with hall effect sensor) -Temperature of each module -Number of cycles Things to calculate: -State of charge (Fuel Gauge; in percent) -State of health (I will give the formula) -Depth of discharge (in Ah) -Internal resistance of each cell in series Other features: -EMI Resistant -Top balancing of cells (passive) at the end of charge (around 200mA is enough) -Output contacts for charger to reduce the current (opening contact) -Output contact to turn off the charger (opening contact) What I need: -Programm Code -Schematics -GUI for WIndows or Android -PCB Design If you need any more Info, please ask.
