Description Header

A Battery Thermal Management System (BTMS) helps to maintain a battery pack at its optimal temperature range of 20° to 45° C regardless of ambient temperature. For each vehicle design, the required performance and cycle life of the battery pack are considered to determine the specific set point for the battery pack temperature.

This Battery Thermal Management System is a complete thermal system solution that maintains the critical operating temperature ranges of vehicle batteries. Design solutions are available for both active and passive cooling circuits.

  • Standard packaging or customized solutions available.
  • Field proven patented master controls system.
  • Specialized battery radiator and condenser specifically designed for BTMS applications.
  • 2 - 10 kW cooling (typically 6 kW at 45ºC ambient).
  • 6 kW passive cooling (10ºC ETD).
  • 2 - 12 kW electric heating down to -20ºC coolant temperature.
  • Total system weight < 60 kg.
  • Operates native vehicle voltages (HV: 400 - 800 VDC / LV: 12 or 24 VDC option).
