About the Poc scp ft-4s bms app PCB

Poc scp ft-4s bms app is an open source STM32 PCB design by cajt, published on GitHub under the BSD-2-Clause license. It is a 4-layer board measuring 85 × 45 mm, with 74 components from 23 distinct parts.

Its main chip is the STM32F072C_8-B_Tx, from the STM32 family. Other key parts include the LMR51430, INA181-A3, SN65HVD230 and TLP222A. By type, the board carries 40 resistors, 11 ICs, 10 capacitors, 6 transistors, 6 connectors and 1 inductor.

It belongs with the power & battery designs in this gallery.

From the project

Proof of concept fault tolerant SCP with a BMS Application.

Fail-safe in a 2-out-of-2 configuration. BMS is implemented in split parts. Both halves have to error free for the battery/BMS to operate nominally. If an error is detected the whole system stops and the electronics disconnects the battery cells from the rest of the system, protecting the cells from leaving their safe operating area in the presence of BMS error.
