The Intelligent House: Tesla’s Home Battery

After revolutionising the electric car industry with Tesla motors, Elon Musk sets his sights a little closer to home.

Brainchild of billionaire and serial entrepreneur Elon Musk, the Tesla Home Battery aims to revolutionise the home energy market.

Causing a sensation in the media when the product launched in May, Musk stated that ‘electricity storage is the “missing link” in weaning the economy off fossil fuels. It is clear that many agree, with the company reporting that it has already received 38,000 reservations

So what have they created?

As expected from the award winning car manufacturer, the Tesla PowerWall is sleek and elegant. Mounted seamlessly on the wall and integrated within the local grid, the rechargeable lithium-ion battery has been designed to retain energy at a residential level for load shifting, backup power and self-consumption of solar power generation.

How will it work?

Identifying that the majority of the home’s energy is consumed in the morning and evening, the PowerWall harnesses solar energy during the day via a solar panel installed on the roof. Using this stored power, the device is able to provides an alternative source of energy during these peak hours. It is also able to store energy streamed via the mains supply at low peak times.

The PowerWall comes in 2 models: a 10kWh weekly cycle or a 7kWh cycle. For those homes which require more energy, Tesla have re-engineered the overall shape allowing multiple batteries to be fitted together. This can provide up to 90kWh for the 10kWh battery and 63kWh for the 7kWh version.

The table below details a generic breakdown of household items with their estimated power usage:

During the products launch, Musk stated that this industry could be, ‘‘bigger than electric cars.’’ Musk added (with typical understatement) that, “electricity storage is the missing link in weaning the economy off fossil fuels.’’
