Measurement layer
Cell voltage monitoring, pack current sensing, NTC mapping and accuracy review for each series group.
BMS design software module
Build the protection stack before you build the board.
Attral Energy software helps teams turn battery pack requirements into a clean BMS architecture: measurement front end, balancing, switching, current sensing, thermal sensing, communication and fault response.
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.
Define battery pack
Chemistry, series count, parallel count, load power, capacity, operating temperature and enclosure assumptions.
Pick components
Select BMS IC, shunt, MOSFET bank, NTC sensors, balancing current, fuse, precharge and communication module.
Validate architecture
Review BMS current rating, thermal sensing density, derating, fault behavior and test requirements.
Try the web-based BMS configurator.
Open design appThe first public version is a concept tool for course learning, consulting and early product planning.
