The iso-BTC supports the full integration of a charge-discharge unit, allowing for the repeated, automated cycling of battery cells under a range of operating conditions, while concurrently recording both the battery’s electrical performance and the heat evolved.  It can also conduct accelerated aging tests, allowing the effect of battery aging on cell performance to be investigated. Battery chemistry, electrode composition, and battery cell type can also be investigated within cell development using the iso-BTC.

Thermal mapping (multipoint temperature measurement) allows the user to identify regions of a battery that generate greater thermal energy to be highlighted.  Along with the thermal behavior characterization of the battery cell over a range of temperatures and (dis)charge rates, this information can be used to inform effective and targeted thermal management strategies within the battery module and pack.

Performance testing

  • Characterizing performance under normal and abnormal use
  • Aging and lifetime performance testing

Battery behavior as a function of charge/discharging rate and temperature

  • Heat release profiles
  • Battery efficiency profiles
  • Battery charging/discharging capacity profiles
