A Tesla Battery for Your Home?

by Nour Bundogji

With the emerging energy storage market, Tesla Motors Inc., best known for their Model S all-electric sedan, announces plans to release a lithium-ion battery to power your home. Elon Musk, Chief Executive Officer of Tesla Motors, stated in an earnings conference call, “We are going to unveil the Tesla home battery, a consumer battery that would be for use in people’s houses or businesses fairly soon.”

What is this battery?

Well, Musk said that it “will be like the Model S pack: something flat, 5 inches off the all wall, mounted, with a beautiful cover, an integrated bi-directional inverter, and plug and play.”

Ben Popper from The Verge says it may be similar to the Toyota Mirai, which “uses a hydrogen fuel cell and gives owners the option to remove the battery and use it to supply electrical power to their homes.” The Mirai has been reported to power the average home for a week when fully charged. However, what sets Tesla’s battery apart from Toyota’s is that it would be a stationary pack that “would live in consumers’ homes, instead of their cars.” Musk said.

Dana Hull and Mark Chediak from Bloomberg claim, “Combining solar panels with large, efficient batteries could allow some homeowners to avoid buying electricity from utilities.” Initially, this sounded like a good deal to me. But then, I realized that Tesla hasn’t released a price for this battery; considering that their Model S was $70,000 MSRP, it may not be a total bargain.

Nonetheless, this is a release to look forward to. The battery is said to enter production in about six months. However, Tesla is still deciding on a date for unveiling their ‘home battery.’
