BMS — Battery Management System Reference#

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

When to Use#

• Designing a BMS for lithium-ion battery packs
• Understanding cell balancing (passive vs active)
• Implementing SOC/SOH estimation algorithms
• Setting up thermal management and protection thresholds
• Evaluating BMS ICs and architectures

Commands#

intro#

bash

scripts/script.sh intro

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

cellbalance#

bash

scripts/script.sh cellbalance

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

soc#

bash

scripts/script.sh soc

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

protection#

bash

scripts/script.sh protection

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

thermal#

bash

scripts/script.sh thermal

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

communication#

bash

scripts/script.sh communication

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

topologies#

bash

scripts/script.sh topologies

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

safety#

bash

scripts/script.sh safety

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