Nichicon Corporation (hereinafter, Nichicon) has released a new lithium-ion power storage system for public- and industrial-sector use. Made for use indoors, outdoors, and even in areas susceptible to salt damage, this compact system employs compartmentalized construction, making it much easier to deliver, install, operate, and maintain. The system has a built-in Scott-T transformer, and the system’s service section has been concentrated into a smaller area so that repair and maintenance requires less space. This has made it dramatically more user friendly than previous products.
In local government evacuation shelters, the system can be used during regular times to shift and reduce electricity peak demand, while in times of natural disaster it acts as a reliable emergency power source that citizens know they can count on. Combined with a renewable energy source, this lithium-ion power storage system keeps the public and industrial sectors environmentally friendly, economically efficient, and ready in case of a natural disaster.
Since the Great East Japan Earthquake of March 2011, Nichicon has delivered numerous public- and industrial-sector-use power storage systems to schools, hospitals, and city halls in municipalities that have received funding under Japan’s version of the Green New Deal, which is aimed at installing emergency power sources in evacuation shelters so that communities are prepared for future natural disasters. So far in fiscal 2014, a total of 22 billion yen has been distributed to 21 municipalities around Japan as the market for public- and industrial-sector-use power storage systems grows steadily.
Drawing on its advanced technological strength and wealth of experience in delivering these systems to customers so far, Nichicon will respond to this growing demand with products boasting both advanced functionality and convenience.
Behind the Development
These days, solar panels come in an increasingly diverse range of capacities, while storage systems also have a wide range of output capacities (Scott-T transformer outputs). And with the trend moving towards more indoor installations, systems need to be able to fit through doorways 800-mm wide and be installed in spaces no more than 5 m².
Nichicon’s latest power storage system meets these needs in a convenient, space-saving package. In addition to flexibility—compatibility with solar panels between 10 and 20 kW and Scott-T transformer outputs between 5 and 20 kVA—the system employs a compartmentalized construction that allows its components to be carried inside separately. And system maintenance and repair can be carried out solely from the system’s front side, meaning less space in the room is required for maintenance.
- Can be installed indoors, outdoors, and (optionally) in coastal areas susceptible to salt damage.
- Compartmentalized construction (separate connection panel, power control panel, and storage battery panel) makes carrying and installation easy. And since all maintenance can be conducted from the front side only, the maintenance space required is half that of conventional systems.
- Depending on customers’ needs and how they will use the system, they can choose a Scott-T transformer output anywhere from 5 to 20 kVA, and have the transformer built into the connection board.
- The built-in 10 to 20kW power conditioner means users can connect the system directly to solar panels up to 20 kW in capacity from various solar panel manufacturers.
- By having the optional transmission function installed, users can gather data on the system’s operation state on an ongoing basis, and any problems that arise will be signaled to the user’s remote terminal. This allows for safe control of the system.
