Cell sim

atopile·cell-sim·elec/layout/default/cell-sim.kicad_pcb

Cell sim is an open source PCB design by atopile: a 4-layer, 220 × 110 mm board with 1152 components (77 distinct parts). It is built around the C2913205, C139797, C709357, C32843 and more. Filed under power & battery.

This cell-sim is designed to mimic a LiPo battery pack for develpoment of the surrounding electronics, like a BMS.

- 16 channels - Open-Source hardware design, you can embed onto your own HIL setup - ⚡️ 0-4.5V and 0-500mA per channel - DMM muxed to each channel for arbitarily precise measurment - Open-circuit simulation on each channel - 📏 16bit ADC feedback for voltage and current - 🔌 USB w/ Python software interface (+ 100MBit Ethernet + WiFi waiting for firmware support)
