Sensata Technologies has announced the availability of its i-BMS battery management system (BMS) for electrified applications up to 60V.

  • Cell chemistry agnostic and compact design
  • Developed for cost-optimized mass-production of applications up to 60V, such as automated guided vehicles (AGVs) and robotics
  • Hot swap functionality and parallel battery pack support allows quick exchange of depleted batteries with fully charged batteries
  • Parallel pack support allows for use of two or more battery packs in parallel allowing OEMs to have smaller battery modules, improving the safety and serviceability of the battery system
  • Measures 65 x 200 mm (2.6 x 7.9 in.)     
  • PCB board is equipped with everything required to manage and maintain a battery system without the need for external components, making it a convenient and cost-efficient for mass production
  • Pre-charge circuit, on-board current measurement, MOSFET power switches for battery disconnect, and a DC/DC power supply are pre-integrated into system
  • Features key components that are ASIL C Safety rated and include self-test capabilities for safety critical measurement circuits
  • Advanced algorithms in software ensure accurate state-of-power (SOP) predictions based on cell internal resistance, voltage and current constraints, precise state-of-charge (SOC) calculations, and (state-of-health) SOH calculated based on aging effect
  • BMS Creator configuration software allows the battery pack designer to create a unique battery setup by defining application specific BMS parameters and safety strategies, optimizing battery operation 
  • Other software features include measurement of rate of change of temperature to predict thermal runaway, dynamical regulation of current in extreme thermal conditions, as well as advanced parameter settings for CAN communication
