Auxiliary Temperature Measurement
Introduction Battery temperature measurement is essential for evaluating safety, longevity, and performance in modern testing environments. Arbin supports three primary sensor technologies—thermocouples (Type T and K), RTDs (PT100), and thermistors (10kΩ)—each available through dedicated auxiliary input modules. These sensors enable precise temperature control, monitoring, and safety logic throughout battery R&D […]
Constant-C-rate w.r.t. actual capacity, rather than constant current with Arbin cyclers
As we all know, the batteries’ capacity degrade by cycle of charge and discharge. If we set the charge and discharge current of a fixed value, such as 1A, 2A,… the length of each cycle will gradually decreases, simply because the battery’s capacity decreases: Cycle time = (Charge Capacity + […]
