EATON Supercapacitors – High Energy Density in a Compact Format

New High-Energy EDLC Solutions

Key features of those components are the fast charging capabilities, temperature stability, flexibility and longevity. Supercapacitors deliver hundreds of thousands of charge/discharge cycles, compared to only hundreds (or a few thousand) in lithium-ion batteries. Moreover, supercapacitors pose zero thermal runaway risk over a wide range of temperatures, making them inherently safer than batteries.

EATON ELECTRONICS, offering a wide portfolio of EDLCs with different mechanical and electrical versions, has recently expanded their selection with particularly high energy density versions for long backup times and space saving. Additionally, the variety and range of available capacitances and sizes has been increased.

HVH (2.7V) and TVH (3V) series are versions of the radial leaded HV and TV series. HVH is available with 2F to 120F in dimensions of 8×12mm to 18×60mm, and TVH offers sizes of 8×12mm to 16×30mm with capacitances of 1F to 30F (table 1).

XVH (2.7V) and XTH (3V), high energy density versions of the large can snap-in series XV and XT, are available with 3 different terminal options (2-pin, 4-pin and lug terminals). The capacitance ranges from 120F to 600F with 22×47mm to 35×72mm for XVH and 100F to 400F with 22x47mm to 35x68mm for XTH. All of them are specified with an max. operating temperature range of -40°C to +85°C (+85°C with voltage derating) (table 2).

• Gaming machine backup
• Pulse power up to 15 kW
• Medical mobile X-ray power

Hybrid EDLC Technology

Another specialty of EATON ELECTRONICS are hybrid supercapacitors. Hybrid supercapacitors are variants of standard supercapacitors that combine the benefits of EDLCs and li-ion technology for improved performance. Inside a hybrid supercapacitor, one of the carbon-based electrodes is replaced with a lithium-doped carbon electrode similar to a battery. With this technology the energy density is increased even further to over 100% greater compared to conventional EDLCs with very long cycle lifetimes compared to lithium-ion batteries. Additionally, the rated voltage is increased as well, to 3.8V.

As with the conventional supercaps, EATON ELECTRONICS has also developed a high energy density version (HSH-series) of the hybrid supercaps (table 3).

Features of the HSH Series

• 3.8V operating voltage for high power and high energy
• Up to 10 times energy density compared to standard supercapacitors
• Low ESR for high power density
• UL recognized
• Low self-discharge ideal for use with batteries

Specifications of the HSH Series

• Maximum rated working voltage: 3.8V
• Minimum rated working voltage: 2.5V
• Minimum allowed working voltage: 2.2V
• Capacitance range: 3F to 1,400F
• Dimensions: 5×12mm to 18×60mm
• Operating temperature range: -25°C to +70°C

Applications of the HSH Series

• Industrial backup/ride through
• Backup for storage servers
• Water and gas smart meters
• IoT energy storage
• Medical backup power/alarm
• Commercial trucks/containers asset tracking

Integrated Power Solutions

This combination of advanced technologies allows EATON ELECTRONICS to offer a wide variety of capacitor solutions tailored to applications for backup power, pulse power and hybrid power systems. They can be applied as the sole energy storage or in combination with batteries to optimize cost, life time and run time. System requirements can range from a few microwatts to hundreds of watts. All products feature low ESR for high power density with environmentally friendly materials for a green power solution.
