Power System Management


Why use Plastic Optic Fiber (POF) around batteries?


 Risks linked to Power Battery Management:

  • Operating risk:  When Battery systems are operational, they can generate significant EMI from the large changes of current over short time scales (large dI/dt), which can cause spikes on digital circuitry and damage micro controllers. The EMI can also cause drive systems to malfunction resulting in current surges producing heat damage, short circuits and also causing fire damage with resulting equipment loss and possibly personal injury.
  • Maintenance risk:  During routine maintenance a short circuit generating a current surge can result in personal injury, fire and equipment damage.


Plastic Optic Fiber Advantages:

  • Plastic Optic Fiber is 100% plastic and consequently does not conduct electricity and cannot therefore cause a short circuit.
  • Plastic Optic Fiber is also 100% immune from electrical or magnetic pickup hence it will isolate command and control digital electronics from the power switching electronics' interference usually located in a UPS or EV charging station. Equally POF can provide high speed data connections between devices without the risk of carrying unwanted EMI/RF interference from one unit to another.
