Battery Management System parts and their functions
4 top-level parts · 86 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Bare PCB | 1× | Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it. |
| 2 | Microcontroller | 1× | Single-chip microcontroller combining a processor core, flash memory, RAM, and peripherals such as timers, ADCs, and serial ports to run the device's control firmware. |
| 3 | Power MOSFET | 4× | Power MOSFET: a voltage-controlled semiconductor switch that turns high currents on and off at high speed in converters and motor drives. |
| 4 | SMD Passive (R/C/L) | 80× | Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board. |
