Lithium Balance 100800

n-BMS Master Control Unit for use with the 100801 or 100809 CMU Cell Monitoring Units

The n-BMS is the next generation scalable BMS for high voltage applications. It is a distributed system in which the Management Control Unit (MCU) communicates with up to 32 Cell Monitoring Units (CMU). Each CMU manages up to 12 voltage channels in series and thus, the n-BMS is rated to manage up to 1000V.

The networked LiBAL n-BMS has been developed around the new communication standard isoSPI, which essentially does not require programmable processors on CMU’s (Slave PCB) in the BMS network. In any application, this is a huge advantage, because it does not require software on the CMU and therefore greatly simplifies in-field main- tenance. In addition, the isoSPI communication network ensure the most cost efficient communication circuit in the market.

The n-BMS is developed to meet all relevant automotive requirements. ISO 26262 compliant design with key components such as Processor, ASIC and PSU carefully selected to meet the functional safety at ASIL C level.

The n-BMS can be configured with up to 32 CMU’s. Each CMU can monitor up to 12 cells in series and thus the n-BMS can monitor in total up to 384 cells in series.

The n-BMS can measure temperature with an accuracy up to +/-1 C and meassure cell voltages with an accuracy of +/-1,5mV, throughout the entire temperature range (-40 to +85 °C).

The n-BMS Creator™ software, enable the battery designer to create a unique Battery design based on the n-BMS hardware. The n-BMS Creator™ software facilitates a unique safety strategy, battery performance optimisation, charge time reduction as well as ensuring the best possible battery life.
