Battery Management Solutions for High-Voltage Energy Storage
High Energy Cell Protection. Battery cell monitoring lines in a stack are vulnerable transient threats in high voltage systems. Consequently, these lines require ultra-fast overcurrent protection to prevent damage to the internal ESD diodes. A good solution is a high voltage (850V) MOSFET device that behaves like a resistor.
Supercapacitor
Supercapacitors are suitable temporary energy storage devices for energy harvesting systems. In energy harvesting systems, the energy is collected from the ambient or renewable sources, e.g., mechanical movement, light or electromagnetic fields, and converted to electrical energy in an energy storage device.
