Battery Management

Battery-monitoring-system
High Voltage battery management systems (BMS) used in today’s complex hybrid and battery electric vehicles require precise measurement of the energy being transferred during charging and discharging of the battery pack. Accurate current measurement is a key input to algorithmically determining the state of charge (SOC) and health of the battery. To meet this need Littelfuse engineers and manufactures current sensors in a variety of packages, measuring ranges, communication protocols and functional safety ratings.
  • Isolated current measurement up to ±1500A
  • High accuracy current measurement
  • +5V or, +12V power supply variants
  • Single / Dual / Redundant outputs
  • Ratiometric analog or digital output protocols
  • ASIL rated versions
  • High sensing accuracy
  • Low offset error
  • Low sensitivity error
  • Compact, customizable designs
