Battery State-of-Charge Sensors
SOC Application Data 07/12/2019
Existing solutionsto measure state of charge rely on labor intensive measurements of cell specific gravity or inaccurate voltage or charge bookkeeping methods.This device is a convenient, accurate and inexpensive solution for real-time direct measurement of the state-of-charge of lead-acid battery cells critical in many emergency power, motive power, automotive and telecommunications applications.
This patented solution is based on fiber optic sensing technology originally developed at one of the nation’s national laboratories. The device effectively measures cell specific gravity the historical standard of battery charge levels and enables inexpensive, accurate and continuous monitoring of battery capacity.
This technology can be easily retrofitted to existing batteries or even incorporated during manufacture thus providing built-in functional assurance and reduced maintenance costs to the user.
The SOC sensor offers additional benefits well beyond specific gravity determination:
The sensor can be powered from the battery itself.
An internal temperature sensing element provides additional information on cell conditions
An alternate version of the sensor provides independent electrolyte level measurement.
Additional software enables automatic and continuous monitoring of battery conditions for 1 to several thousand batteries on-site or over the internet.
The best news is all of this is offered at a cost less than a good quality voltmeter
