EDLC Cell Balancing IC

ROHM’s BD14000EFV-C self-contained cell balancing IC utilizes a shunt resistor method for EDLC cell balancing operation. All necessary functions are integrated on a single chip, facilitating design while contributing to further miniaturization.

• Self-contained EDLC balancing function
• Supports 4 to 6 cells connected in series
• Shunt resistor method provides simple cell balancing operation
• Adjustable detection voltage ensures compatibility with a variety of EDLC output voltages (2.4 to 3.1 V in 0.1 V steps)
• Multi-stage IC connection possible, enabling easy scalability
• Reliable control/overvoltage detection and self-check functions

• EDLC systems
  • EVs, HEVs, and stop-start-equipped vehicles
  • Regenerative energy storage systems for industrial machinery and construction equipment
  • Power stabilization devices such as UPS
