Commercial vehicles have high voltage, high energy battery packs that have cells, distributed across several modules & sub-modules, connected in series and parallel. Distributed BMS architecture allows for the Slave BMSs to be connected close to the individual modules/submodules which inturn eases integration and simplifies wiring. These slaves are further interconnected and connected to the Master BMS  through isolated wired communication interfaces.

High voltage batteries ( > 60V) require adherence to several safety standards which in turn call for critical safety features to be present in the BMS. Maxwell BMS includes such features as High Voltage Interlock, Insulation Monitoring Device Interface, HV Measurement channels which can integrate with the vehicles at a system level and aid in meeting the safety goals.

From basic configurability such as nominal current, cell chemistry, cell S&P layout to  advanced configurability such as SOX tuning, configurable RDC, SOP, CAN,  are readily supported on Maxwell BMS through an easily accessible application layer. With this application layer, lead time in tuning the BMS as per the vehicle’s needs is faster and simpler.
