Toyota releases storage battery system for residential use

21 Comments

Toyota Motor Corp has developed batteries based on the concept of "safe, long service life, high-quality, good value for price, and high performance." Toyota said the technology utilizing many years of electrified vehicle development as well as on-board parts and units has been used to create the O-Uchi Kyuden System, a home storage battery system.

Pre-orders for the system started Friday, and sales in Japan will begin in August through home builders and general construction companies.

The O-Uchi Kyuden System uses electrified vehicle battery technology such as Toyota's battery control to provide a rated capacity of 8.7 kWh and a rated output of 5.5 kWh. This ensures safety and provides a supply of electricity to the entire home not just in normal situations, but even during power outages caused by natural disasters.

In addition, by linking with a photovoltaic system, it can supply the appropriate amount of electricity based on customer needs throughout the day and night. Toyota believes that using this system will encourage the use of solar power which is a renewable energy.

Unique to Toyota, the system supports supplying power from electrified vehicles (HEV, PHEV, BEV, FCEV) at 100V AC, and can use electricity stored in electrified vehicles as a backup power source during power outages, allowing users to live with peace of mind.

In addition, future moves to IoT using a wireless LAN router connected to a hybrid power conditioner allow for storage capacity, operation mode, and other settings to be viewed and set in real-time from a dedicated app on a smartphone or tablet (as of now, only available in Japanese).

power outages caused by natural disasters

Those few words, and it will sell in numbers. The typical Pavlov reflex. How often had you a power outage during your lifetime so far? You see… Anyway, I like that idiotic part, where you fill up your ev car and then draw the power from it during a disaster, instead of fleeing the dangerous scene in time with a full loaded car. So great.

For tech like this we need the economies of scale and labour costs that only China can do. We also need the economy to be strong so people can invest in such technologies.

If governments choose to block of surcharge Chinese imports, domestic equipment will be too expensive. If they hammer the economy with Russian sanctions, border charges and migrant labour bans, people will be too poor to adopt this sort of tech.

So ultimately, whilst we need to switch to distributed green energy production, our governments are blocking it at every turn.

The article is about home storage batteries

And what exactly do YOU know about home storage batteries?

When you're in a hole it's usually best to stop digging.

You should take your own advice.

Interestingly enough, the word "efficiency" isn't mentioned anywhere in the article.*

So what? It doesn't have to be. But that is what they are talking about.

As previously mentioned, I both read and understood the article and its practical implications and limitations.

Obviously not

The article is about home storage batteries and you started wittering about "gas" and the Russia/Ukraine conflict neither of which have anything to do with the subject of the article.

i miss very crucial information.

price for this all incl

comparation for electricity bills with system and without system.

without this this is just simple AD nothing else.

there is nothing to stop you from depleting your car battery to a point where you don't have the capacity for your next morning's journey if that journey needs most of the capacity. The technology is not yet perfected and statements such as this are fairly meaningless:

There is absolutely NO PROOF whatsoever of that.

"In addition, future moves to IoT using a wireless LAN router connected to a hybrid power conditioner allow for storage capacity, operation mode, and other settings to be viewed and set in real-time from a dedicated app on a smartphone or tablet"

It is relevant because we are talking about efficiency and it is obvious that you haven't read the article properly.

When you leave your car in the evening you know how much fuel is in the tank and you can be fairly confident that the same amount will be there the next morning.

There might not be too much "peace of mind" if you jump into your gas guzzler car to go to work one morning and find you don't have enough gas because of the Russia Ukraine war.

There might not be too much "peace of mind" if you jump into your electric car to go to work one morning and find you don't have enough battery reserve to get there as you've used it all powering your house during last night's power outage.

This is definitely worth a closer look but without any rose-tinted spectacles.

J-technology once again demonstrates its cutting edge superiority, with this high quality, viable, practical, cost-efficient storage battery system that offers consistent source of energy. for every-day living.

It is good to have real competition to Tesla's Powerwall and solar panel installations. Both are very expensive, but happened about 5 yrs ago and have systems deployed world-wide. Too bad the installations are 3x more expensive than normal, non-Tesla, solar panels alone. I've seen Powerwall and Tesla Solar purchase and install estimates of $65K+. Normal solar panels for the same house with all the installation and computer stuff commonly used is $20K-ish.

Honda had their H₂ power system as part of the FCX program. Guess that is dead? https://www.autoguide.com/auto-news/2012/03/honda-fcx-clarity-fuel-cell-powers-japanese-house-for-six-days.html Honda FCX Clarity Fuel Cell Powers Japanese House For Six Days The bad thing about the FCX is that it uses natural gas to create H₂0 and H₂, if my memory is correct. Methane is 3x worse than CO₂ as a greenhouse gas. OTOH, the hot water would be nice and using solar to provide power for the methane -- H₂ conversion would be a good thing. H₂ brings issues. It is like a corrosive acid for all metals - making them brittle and H₂ always leaks, so long term storage is always a problem. It can't be delivered like propane, just a few times each year.

Japan's answer to Tesla's Powerwall. This is tech to get into as an investor and as a consumer. Even without solar panels, it gives you a household UPS during power outages.

Concerns? I doubt it will cheap, even if it is good VFM, so not an elective option for most people. It might be an idea to demand a residential battery be included as standard with all new builds than can accommodate them.

I am a little worried as to where all the raw materials are going to be sourced for all the batteries in EVs and now residential/commercial property batteries. Sea floor mining would cause environment carnage.

The app may be unwise. It creates a dependency (upon other systems/tech) and a security risk. I'd rather have a plain old-fashioned remote control. After a big quake, your internet is likely to go down, and anything dependent upon it will become a paperweight.

More options for these house batteries are welcome, it is still too early to go completely out of the grid, but compared with a few years back it seems more and more convenient.

Sounds like an ad for their product to me...

Id love a good solar, battery set up after previously using off grid setup for 11 years.

If Toyota stamped their name on it ,

Then i want one...!

Huh?

Yes, well, wow, so is anything new there apart from the name? And the price is… seriously… not mentioned.
