Measurement layer
Cell voltage monitoring, pack current sensing, NTC mapping and accuracy review for each series group.
BMS design module
Build the protection stack before you build the board.
Turn battery pack requirements into a clean BMS architecture: measurement front end, balancing, switching, current sensing, thermal sensing, communication and fault response.
Architecture
Three layers, one system
A useful BMS design covers sensing, switching, protection, telemetry and test planning — not just an IC choice.
Protection layer
Over-voltage, under-voltage, over-current, short-circuit, temperature limits and charge-inhibit logic.
Control layer
MOSFET or contactor strategy, precharge, CAN/UART telemetry, data logging and service diagnostics.
Workflow
Online design flow for practical BMS decisions.
Start with pack topology, select functional modules, review calculated ratings and export a concept spec for engineering discussion.
- BMS current rating vs load, checked automatically
- Thermal sensing density review per series group
- Fault behaviour & test requirements in the spec
Define the battery pack
Chemistry, series count, parallel count, load power, capacity, operating temperature and enclosure assumptions.
Pick components
BMS IC, shunt, MOSFET bank, NTC sensors, balancing current, fuse, precharge and communication module.
Validate the architecture
Review current rating, thermal sensing density, derating, fault behaviour and test requirements.
