The BattLab-One estimates the battery life of your IOT project using the DUT cutoff voltage, battery state of charge data, event duration, and captured active and sleep event current profiles.
-
Captures both active event and sleep mode current
-
MSP430 microcontroller based device that simulates standard batteries for Li-Ion, LiFePO4, Alkaline, NiMh, NiCd
-
Provides voltages of 1.2V, 1.5V, 2.4V, 3.0V, 3.2, 3.6V, 3.7V, 4.5V at up to 450 mA.
-
Trigger input to capture firmware states and their impact on overall battery life
-
1kHz Sample rate, 16 bit delta-sigma ADC
-
Long active event capture duration from seconds to hours
-
Extremely low burden voltage across all ranges (BattLab-One provides PSU output)
-
Provides “what-if” optimization by letting you change your battery, current profiles, active and sleep duration as well as cutoff voltage
-
Features the ability to save profiles so you can compare your DUT current profiles
-
Interactive/detailed active current plot so you can look for anomalies and identify performance
