Industrial robots generate significant regenerative energy during deceleration and stopping. In many control panels, this energy is still wasted as heat via regenerative resistors. Panasonic's Supercapacitors (Electric Double Layer Capacitors / EDLCs) instantly store this unused energy and reinject it during the next operation, reducing power consumption by approximately 600 kWh per year.
Furthermore, since Supercapacitors rely on physical adsorption rather than chemical reactions, charge/discharge cycles have minimal impact on their lifespan. They require no complex charge/discharge control, drastically reducing maintenance burden.
Current Situation: Regenerative power generated during robot deceleration is largely dissipated as heat through regenerative resistors.
Impact: This results in rising power costs, increased cooling loads, and higher CO₂ emissions—affecting both operational efficiency and environmental targets.
Challenge: There is a lack of high-power energy storage devices capable of instant storage and safe reuse during high-frequency operations.
Current Situation: Secondary batteries degrade chemically, while regenerative resistors face short lifespans and high failure rates due to thermal stress.
Impact: Frequent replacements and maintenance stops lower line availability and increase maintenance workloads.
Challenge: Engineers need a long-life energy storage device capable of withstanding repeated cycling to simultaneously cut maintenance man-hours and material costs.

Current Situation: With decarbonization KPIs and pressure to reduce contracted power capacity intensifying annually, energy optimization has become a critical management issue.
Impact: Insufficient measures can negatively affect ESG ratings and business continuity, alongside the risk of rising unit power prices.
Challenge: A solution is required to cyclically utilize regenerative energy and quantitatively improve the energy efficiency of the entire factory.
By instantly storing and reusing regenerative power previously wasted during braking, power consumption can be reduced by approximately 600 kWh per robot per year. This simultaneously reduces electricity costs and CO₂ emissions.

Utilizing physical adsorption rather than chemical reactions, Supercapacitors exhibit minimal degradation. Testing confirms durability exceeding 1 million charge/discharge cycles. This extends the replacement cycle to more than 10 times that of secondary batteries, significantly lowering the risk of maintenance downtime.

Challenge:
Frequent braking generates regenerative power that is dissipated as heat by regenerative resistors, increasing both air conditioning loads and electricity costs.
Supercapacitor Solution & Benefit:
Supercapacitor buffer units attached to robot axis motors store energy during deceleration and reinject it during acceleration. Reduced annual power consumption by approximately 600 kWh; lowered cooling load.
Challenge:
Explosion-proof painting booths require minimal heat sources. However, regenerative resistors create localized heat buildup that can affect coating quality.
Supercapacitor Solution & Benefit:
Distributed Supercapacitor packs on each arm axis instantly absorb and reuse regenerative power. Suppressed booth temperature rise; reduced cooling airflow by 7%; minimized coating defects.
Challenge:
Repeated 'stop-and-go' cycles every 0.5 seconds create large peak currents, necessitating over-specified power supplies and cables.
Supercapacitor Solution & Benefit:
High-power wound-type Supercapacitors added to the control panel buffer peak loads. Reduced power supply capacity by 20%; enabled use of thinner-gauge cables, reducing wiring weight by 1.8 kg.
Challenge:
Lightweight design and minimal maintenance downtime are essential, but secondary batteries add weight and require labor-intensive replacement.
Supercapacitor Solution & Benefit:
Replaced batteries with chemical-degradation-free Supercapacitor modules capable of withstanding over 1 million cycles. Eliminated battery replacement; reduced annual maintenance hours by 90% and arm mass by 0.9 kg.
