Appliances: The Future is Battery Powered

[combo52]

Wow, don’t tell the owners of

The over 26 million electric cars in use around the world,

I guess I’ve been doing it all wrong with all my electric power tools, my lawnmower, chainsaw, string, trimmers, leaf blowers, etc. etc.

They sure are a lot safer than the gasoline powered lawn tools I used to use.

My rooftop solar panels are running my house beautifully today on a sunny afternoon, keeping all my food cold, frozen food in the freezers, dishwasher is humming along about to go down and do laundry, and in spite of doing all this, I will be sending about 30 kW back into the grid to help my neighbors Keep their lights on today.

This sure strikes me as a solution looking for a problem. Really in the grand scheme of things how many homes aren't wired for 240v AC service?? Yes one may have to run a new line to the kitchen and that will cost money, but I'd wager less than the additional costs of putting a big battery in the appliance. You also make the appliance less efficient because of charge/discharge conversion efficiency losses. I'll go out on a limb and say this idea never gains any traction.

The idea of power backup makes a little sense, but just spend the money backing up the whole house perhaps. Adding a battery/inverter to the home is good security, can allow for off peak energy shifting and integration of renewable sources too.

Battery back up for electric ranges

I agree I don’t think this is gonna be a popular option, especially with the high-end ranges they’re talking about in the article.

But I could see a fairly significant market to retrofit old apartments in DC, New York, etc. etc. there are a lot of old buildings that are very under wired and cannot easily install 240 V lines and a lot of these buildings are desperate to get rid of the gas ranges because of the gas leaks that they’re constantly dealing with in the old plumbing. I know of an apartment building in a nice part of downtown DC senior Dupont Circle where they have several apartments they can’t rent because the line that snakes all the way from the basement to the gas stove has a leak in it somewhere, and they’ve had to shut off the line, this type of stove would make the apartment rentable again easily.

Usually the only thing gas in the apartments is the gas range and the electrical panels have usually been upgraded slightly to where they could easily run This range, they’ve been upgraded to run window, air, conditioners and microwave, ovens, etc.

With some power company or governmental incentives a basic electric range With battery back up, might prove quite advantageous for some of these buildings but I agree it’s not gonna become a common place thing. Nice kitchen throughout the country.

There are almost no single-family homes that cannot easily have a 240 V line run for the range. It will soon be simple just to divert the 240 V line for the electric dryer And plug in a 120 V heat pump dryer in anyway.

Back up batteries for the home already are a thing here. Even Ikea sells them. Ikea’s are 3758 euro for 5kWh. They have models up to 30 kWh. Other brands are Tesla, LG, Huawei, Solarwatt, Solar Edge and Green Rock. The last one is a salt water battery.

If you have a lot of money to spend you can even get a 1000 kWh one for 1 Million Euros.

I guess our 230 Volts system is a big advantage.

I no longer have the electric car-traded it in to a hybrid.Like that better.I do still use battery tools,ride mower and push mower.EGO Tools-DeWalt and Milwaukee.All kitchen appliances still corded.
