SHL_Pod_PrimaryBMS

STM32 Nucleo-F746xx test environment with a library of supported API for the Primary BMS: Orion BMS Jr

Connections / Wiring

STM32 Nucleo-F746ZG <-UART-> Orion BMS Jr
or
STM32 Nucleo-F746ZG <-CANdapter-> Orion BMS Jr

ElCon Charger, Orion BMS Jr (via CANdapter), and STM32F7 communication via CAN2.0b (extended ID)

Battery Pack Configuration

Primary Pack Characteristics
48V 26Ah 18C (14S 10P)

Individual Cell
Sony US18650VTC5A - Lithium Ion "18650" cylindrical cell

Electrical Ratings
I_cell_rating = 25A_ctns, I_pack_rating = 250A_ctns
V_cell_empty = 3.0V, V_cell_nominal = 3.6V, V_cell_full = 4.2V
V_pack_empty = 42.0V, V_pack_nominal = 50.4V, V_pack_full = 58.8V

Module Construction
Each 'super-cell', in actuality, is a '5x2' (5 by 2) module which is comprised of 10 '18650' cells connected in parallel, but constructed as 2 rows of 5 cells.

Pack Configuration
The primary battery pack is 14 of these 'super-cells' connected in series.
