# BMS — Battery Management System Reference

Quick-reference skill for battery management systems, cell monitoring, and pack safety.

When to Use

Commands

`intro`

scripts/script.sh intro

Overview of BMS — functions, architecture, and why every Li-ion pack needs one.

`cellbalance`

scripts/script.sh cellbalance

Cell balancing methods: passive (dissipative) vs active (redistributive).

`soc`

scripts/script.sh soc

State of Charge estimation: coulomb counting, OCV lookup, Kalman filter, impedance.

`protection`

scripts/script.sh protection

Protection circuits: overvoltage, undervoltage, overcurrent, short circuit, temperature.

`thermal`

scripts/script.sh thermal

Thermal management — air cooling, liquid cooling, phase change, heating in cold.

`communication`

scripts/script.sh communication

BMS communication protocols: CAN bus, SMBus, I²C, UART, and data frames.

`topologies`

scripts/script.sh topologies

BMS architectures: centralized, distributed, modular — and IC selection.

`safety`

scripts/script.sh safety

Safety standards, failure modes, and functional safety (ISO 26262, IEC 62619).

`help`

scripts/script.sh help

`version`

scripts/script.sh version
