Peak NanoPlex™ Capacitors Built to Charge Faster, Run Cooler, and Last Longer, at Lower Cost.

NanoPlex capacitor films are engineered for modern DC fast chargers to deliver faster charging cycles, cooler operation, and 5x longer service life. 

  • 135°C Stability with No Derating: Maintains performance under heat with no need to oversize systems or derate under high temperatures.
  • 50% Lower Dissipation Loss: Runs cooler and more efficiently, minimizing energy waste and reducing HVAC load.
  • 5x Longer Service Life: Fewer replacements, less downtime, and reduced service truck rolls or part swaps.
  • Compact and Lightweight: Enables smaller stations with fewer components, simpler cooling, and faster install times.

High-Temperature Capacitance That Extends Peak Charging Output.

  • At high power, DC fast chargers switch rapidly and run hot, wasting energy as heat, shortening component life, and forcing chargers to taper power early, keeping drivers plugged in longer.
  • NanoPlex capacitors deliver full capacitance up to 135°C with very low dissipation, cutting self-heating, and sustaining higher charge power longer under demanding loads.
  • DC fast charging stations run cooler, finish charging sessions faster, and serve more vehicles per day with lower operating costs and greater customer satisfaction. 

More Uptime. Faster Sessions. Higher Throughput.

  • High power cycling and heat stress in DC fast chargers accelerate capacitor wear, causing costly maintenance, downtime, and longer charging sessions that are frustrating for drivers.
  • NanoPlex capacitors deliver full capacitance up to 135°C with ultra-low loss, reducing self-heating and sustaining higher power under heavy use.
  • Charging stations last longer, charge faster, and serve more vehicles per hour, lowering costs while improving uptime, throughput, and customer satisfaction.

Advanced Dielectric Film for High-Power, High-Temperature Charging Hardware.

  • DC fast chargers face heat, ripple, and high duty cycling that accelerate capacitor wear, leading to costly replacements, downtime, and frustrated drivers.
  • NanoPlex capacitors sustain full capacitance up to 135°C with ultra-low loss, reducing self-heating and extending service life under heavy use.
  • Stations run longer, with higher uptime, consistent throughput, and lower operating costs, improving both reliability and customer satisfaction.

Lower Cooling Needs, Lower Maintenance, Lower Cost Per Charge.

  • Traditional capacitor banks require oversizing and heavy cooling to handle heat and ripple, raising upfront cost, expanding footprints, and driving a higher price per charge.
  • NanoPlex capacitors last 5x longer, hold full capacitance up to 135°C with ultra-low loss, reducing self-heating so designs need less cooling, and less maintenance.
  • Charging station operators can expect lower maintenance, cooling, and operating costs per site, and deliver reliable fast charging that scales with customer demand.

NanoPlex™ Solves DC Fast Charger Capacitor Challenges

In 800–900 V EV architectures, conventional capacitors derate above 85°C and shrink under high ripple currents, forcing oversized banks and added cooling. This increases mass and losses in inverter and DC-link duty. NanoPlex LDF maintains full capacitance up to 135°C with no derating and a 50% lower dissipation factor, limiting self-heating and preserving stability under thermal and electrical stress.

In fast-charging duty, traditional capacitor banks lose stability under ripple and generate self-heating at modern switching speeds in the inverter and DC-link, forcing vehicles to taper current earlier. NanoPlex LDF maintains capacitance at 135°C with a 50% lower dissipation factor, limiting self-heating and allowing sustained higher charging power. This shortens charging sessions and increases charger throughput.

In inverter and DC-link duty, conventional capacitor banks heat rapidly during acceleration, towing, or grade-climbing, which can trigger torque limits and shift more peak demand onto the battery. NanoPlex LDF maintains full capacitance up to 135°C with a 50% lower dissipation factor and low impedance, reducing self-heating and sustaining surge power delivery without early derating. This preserves throttle response and eases battery strain.

At faster switching speeds in 800–900 V inverters, traditional capacitors dissipate more energy as heat, driving self-heating in inverter and DC-link duty and increasing cooling demands. NanoPlex LDF delivers a dissipation factor 50% lower than conventional capacitors, reducing internal heating, improving efficiency, and lowering reliance on auxiliary cooling hardware.
