Large-sized lithium ion accumulator "Desk top" PCs with desktop PCs running continuously for 30 hours Review of actual equipment

A large-sized lithium-ion battery that can store electric power in case of a power outage due to an earthquake or typhoon "Power islet". Charging is done just by leaving it connected to the outlet, charging is performed instantaneously to the connected equipment at the time of a power failure, charging with inexpensive power at night, the amount of electricity used during the day increases It seems that it is a rather sophisticated product that you can also set the "peak shift" to use during the time period, so I developed this productErie powerI decided to go to the company and check the performance of the actual machine.

I came to a building near the Osaki station in Tokyo.


The reception logo looks something like this. It seems that the three vertical lines represent the positive electrode, the negative electrode, and the separator which are the basic structure of the battery. By the way, the ratio of long line to short line isGolden ratioIt is said that this number is used everywhere from the company's business card to the design of the housing of the storage battery.


When entering the company, the prototypes of "power isre" were lined up.


To be given to companies that meet the requirements of quality management established by the International Organization for StandardizationISO 9001It seems that you have already obtained certification.


The body of "powerful" is like this. "Narita Express handled the car body"GKID"Is in charge of the design, it has become quite stylish as a battery.


It is about 70 centimeters in height, and when it ranks with an adult man, the top is about the thighs.


Looking from above it has a handle like this ... ...


Hold the bar under the handle and the wheel will be unlocked. In addition, since the wheels are fixed to the state without grasping the steering wheel, there is no worry of rolling without permission.



It's heavyweight with a weight of about 62 kilograms, but since it has 4 wheels on the bottom, it can be moved without difficulty by pulling it with a corner stroke like a suitcase.


The side is like this. The enclosure is made by extrusion processing of aluminum, and there is strength enough not to bite even if you kick it all the way.



One leg on the left and right for preventing falling over. It can be used stably even in situations where aftershocks continue.


It was actually used in the field at the time of the Great East Japan Earthquake as follows.


There seems to be various gimmicks on the back, so let's check the details below.


Open the lid at the top left ... ...


An antenna for communication assistance appeared. "Erie power" is connected with KDDI's 3G network, and information collected by the temperature sensor etc. is transmitted to the management center so that if there is a danger of failure it will be informed to the user.


With such a feeling, it is possible to install an antenna with a suction cup beside the main body.


Remote monitoring will be effective if au's cell phone is connected, so it is safe even if it is installed in a remote site such as a hut. In addition, it can be set to guide guidance of earthquake early warning by voice.


The exhaust port of the waste heat fan is installed in a recessed place.


Even if it is used exactly on the wall as follows, the exhaust port will not close up and it will not overheat.


Since the air intake of the front has a filter, it is safe to use it in a somewhat dusty environment.


The filter can be detached with this feeling.


The following 16 battery cells are installed inside.


In normal prismatic batteries, it is likely that crushed electrode rounded cords are often put into a square case, but "Power-Rile" batteries are stacked with electrodes like "Tissue box tissue" It seems that it arranges it densely and increases energy efficiency.


There is thickness of phone book as seen from the side.


This battery cell has acquired the safety standard certification for the first time as a large-sized lithium-ion battery by the international third-party test and certification body "TÜV" which is verifying the safety of the product, and even if it pierces the nail It seems to have stability enough not to cause a short circuit.

·TÜV Rheinland Released

According to the experiment carried out by Ellie Power, it seems that a general lithium ion battery sometimes ignites while blowing a spark with a short circuit when stabbing a nerve.


On the other hand, what is built in the "power islet" maintains a stable state even when piercing the nails, it seems that it can be operated as it is, although it is not recommended usage.


It looks like this actually connected to the power supply


When used in a house equipped with a power management system called "smart house", it is possible to fine-tune the settings such as "energy saving priority" and "power saving priority" by connecting with a LAN cable.


Since it can also be connected to a direct current power supply, you can charge it by connecting the terminal and the solar cell directly.


It can also be recharged by connecting with a 100V outlet for home use.


When connected to an outlet, the battery is bypassed and an alternating current flows directly to the connected equipment.


Fans and heaters can be used like this. You can connect up to 1000 watts of equipment.


In this time, the power outage state is reproduced in a pseudo manner by extracting the outlet.


It switches automatically to power supply from the battery in a short time of 15 milliseconds.


Even in the event of a power failure, you can drive the fan, heater, desktop PC. In this state, we use about 680 watts of power, but it is possible to use for up to 3 hours continuously. It seems that it can be operated continuously for up to 30 hours only with general PCs and electric fans.


Please check the movie below to see how you actually pull out the outlet and switch to power supply from the battery. You can also set the mute setting for the warning sound flowing in the image.

Household storage battery "Power-Rile" moves like this at power outage - YouTube


If it corresponds to touch operation and "Peak shift mode" is selected, power supply from the battery is started automatically at the time automatically determined every day.


In this state, it is convenient when you need to conserve electricity in the midsummer daytime because all the connected equipment is powered by batteries.


In fact, it can be seen in the following movie how to automatically switch to peak shift mode. Since it is almost silent and it is not a translation of somewhere parts, it makes me uneasy as "Do you really switch?", But if you do it everyday in an office or other place, it might be more than quiet this way.

"Power isre" is leased for 36,000 yen per month for corporations, and in the case of small and medium enterprises subject to supplementation by national and prefectural governments, up to 3 minutes 2 subsidies can be received and used I will.

Also, for individuals nowDaiwa HouseAlthough it is possible to purchase only with a set of houses that are handled by the company, it is said that sales as a standalone is scheduled to start soon, so it seems like it will be available for purchase in 2012. Although it seems that the price is scheduled for the latter half of the 1 million yen range, here too it is likely that assistance from the country and prefectures will be carried out, so the amount actually paid is likely to be a little cheaper. Daiwa House is planning to be sold for individuals as a major agent as well.

It is not a cheap price to buy yet, but if mass production is in place, it will be possible to offer inexpensive products as well. Considering the case of securing electricity in case of disaster, charging electricity from solar battery and using it for peak shift, it can be said that it is one of the strongest classes that can be purchased individually, so check it out if you are interested.
