Fuel Gauges

Fuel Gauges

MPS Fuel Gauge leverages a sophisticated mixed mode algorithm to provide a complete set of estimates beyond state of charge ( i.e. time to empty, full, available power, state of health) -  key in improving the end user experience. Our Pack Side Fuel Gauge can be paired with any AFEs with cell-level ADC readings and unlock all the potential of any existing designs for battery pack with 2 or more stacked cells. Get your setup going quickly with our Reference Designs paired with a GUI featuring a simple wizard and the ability to record and a plot.
