Disaster Prevention and BCP Measures [Hospitals, Clinics] Emergency Power Supply! Mobile Storage System

Disaster Prevention and BCP Measures [Hospitals, Clinics] Emergency Power Supply! Mobile Storage System

We recommend securing a minimum power supply in preparation for disasters and unexpected power outages.

"CUBOX" is a portable power storage system that can be easily used with the push of a button. It can supply power for approximately 30 hours as a backup power source for office buildings (about 10W for communication devices, about 70W for information terminals, and about 20W for lighting fixtures). *For CUBOX 3.3kWh. Traditionally, the mainstream approach to disaster prevention and BCP (Business Continuity Planning) measures has been the use of generators, but the assumption that "generators will definitely operate" is being reevaluated. In fact, during the Great East Japan Earthquake, about 30% of generators did not operate due to safety device activation and maintenance issues caused by the earthquake. Backup power sources are necessary to maintain the functionality of hospital facilities. [1] Emergency backup power for critical equipment such as pharmaceutical refrigerators [2] Backup power for communication devices as a means of communication among staff [3] Backup power for lighting fixtures in patient wards As part of disaster prevention and BCP measures, there have been implementations in over 50 municipalities and more than 30 hospitals to date. <Features> - Does not emit carbon monoxide or unpleasant odors, making it usable indoors. - Designed for quiet operation, allowing use at night. - Provides a better waveform (pure sine wave) than commercial outlets, making it suitable for precision equipment. - Easy maintenance. - Utilizes reliable Japanese-made lithium-ion batteries and power sources.

The "HPP-2000/HBB-1000" is an off-grid power source that can be used in places without electricity, just like a regular outlet. It offers an overwhelming capacity and high output that is not found in conventional portable power sources. It can be transported without restrictions on the means of transport, and it is equipped with casters for easy mobility. It has been adopted as a backup power source for the yeast freezer at a sake brewery. There are no other portable power sources from other companies that can back up refrigerators, and it was chosen because it can be taken out during emergencies. *For more details, please download the PDF or feel free to contact us.*

Battery charger as AC-DC power supply!? 'NPP Series'

Battery charger as AC-DC power supply!? 'NPP Series'

It is a 2-in-1 designed device that allows the use of battery charger mode and power supply mode in a single unit.

Battery Charger "NPP Series" This product features two modes: battery charger mode and power supply mode. In battery charger mode, it performs excellently as a charger utilizing stage charging! However! In power supply mode, it is possible to charge the battery while also connecting a load to the unit, thereby providing a stable DC output! In the "3-stage charging" of the charger mode, it transitions from bulk charging to absorption charging and then to float charging. However, if a minimal load such as 5A is used, it may not transition to float charging and the charging will stop (it will not reach full charge). However, by using power supply mode, it allows for both full charging and stable supply to the load. Once the battery is fully charged, it will only supply the load stably. By disconnecting from the battery, it can also be used as an AC-DC power supply. For more details, please visit our website or view the catalog below.

Auxiliary power source in fuel cell vehicles

Auxiliary power source in fuel cell vehicles

Equipped with a high-output auxiliary battery! It is possible to combine the advantages of fuel cell vehicles and EVs.

Due to considerations for the SDGs and environmental issues, the transition from gasoline vehicles to environmentally friendly vehicles is rapidly progressing worldwide. However, there are concerns about resource shortages when it comes to fully electrifying vehicles using only lithium-ion batteries, which are currently mainstream in electric vehicles. Additionally, battery electric vehicles (BEVs) face the challenge of long charging times. On the other hand, fuel cell vehicles (FCVs), which generate power using hydrogen and oxygen to drive motors, are expected to be the cars of the future.

Auxiliary power source in fuel cell forklifts

Auxiliary power source in fuel cell forklifts

High-output auxiliary battery! Explanation of the features and technical advantages of lithium-ion capacitors (LIC).

The government has set a goal in its basic strategy for realizing a hydrogen society to promote the adoption of 10,000 fuel cell forklifts by 2030. Forklifts are essential transportation devices in manufacturing and logistics warehouses, with a global market size of approximately 1 million units per year. In Japan alone, there is a demand for about 10,000 units, and this demand is expected to increase further with the development of e-commerce. Traditionally, forklifts have been predominantly engine-driven, using gasoline and other fuels, but engine noise and exhaust emissions have become significant issues.

Emergency power supply that backs up the entire building for 6 hours before and after a power outage without interruption.

Emergency power supply that backs up the entire building for 6 hours before and after a power outage without interruption.

Introduced as a measure against unexpected power restoration accidents! Power supply to telephone and internet equipment can be sustained for about 10 hours.

We would like to introduce a case where the "Personal Energy Portable" was implemented in the Esca underground shopping district, which represents Nagoya. The company had to conduct a full building power outage for about six hours during the statutory electrical equipment inspection, which required coordination for personnel and phone responses, including transfers, due to the contractor's needs and the complete closure of the building during regular inspections. After the implementation, it became unnecessary to secure personnel and handle phone responses, including transfers, in line with the annual statutory electrical equipment inspection schedule. [Challenges] ■ For service industries with limited holidays, being cut off from external communication poses a significant risk. ■ During the legally mandated annual electrical equipment inspection, a power outage lasting several hours cannot be avoided. *For more details, please download the PDF or feel free to contact us.
