Why Monitor Battery Temperature?
Battery temperature is a key indicator of 3 major parameters of a battery pack:
An effective Battery Management System (BMS) will include several temperature sensors to aid with identifying and regulating these parameters.
Monitoring battery temperature swiftly identifies faulty cells, prevents overheating adverts thermal runaway. Common causes of heightened battery temperature, like ground faults, shorted cells, inadequate cooling, or unregulated charging, can be detected through temperature monitoring, preempting catastrophic failures such as thermal runaway and potential fires.
Batteries operate optimally within a typical temperature range of typically 15-35°C (range may vary with battery chemistry and application). Monitoring temperature ensures the pack functions efficiently within this range. Excessive heat accelerates degradation, while extreme cold slows down performance.
Precise temperature control minimises cell degradation, physical distortion, and chemical changes, thereby extending the battery pack’s lifespan and avoiding premature, costly replacements.
ATC Semitec’s product range covers various battery temperature monitoring needs :
- External Pack sensors (for battery surface/busbar/terminals) – STS2 Ring sensors
- Between Cell sensors – AT-11 / AT-4 / JT / NTC & RTD SMDs / YAGEO Nexensos EC-3032
- In Cell sensors – Semitec FT
For over-temperature protection, we offer thermal cut-outs that interrupt circuits at predetermined temperature limits.
These can be mounted on a battery pack or even between cells for rapid response.
