Elon Musk reveals Tesla Powerwall – a home battery with green credentials


Tesla’s CEO Elon Musk has taken a break from his electric car business temporarily to make a presentation at the company’s Southern California design centre, to announce the Tesla Powerwall – a wall-mounted rechargeable lithium ion battery that could reduce your reliance on fossil fuels and also reduce your power bill.

Tesla Powerwall paves way to a cleaner world

The new home battery will ship in three months, and Musk claims it can provide users with many advantages over traditional power sources and helping pave the way to a cleaner world. Home that have solar panels installed should already be able to use Powerwall to store surplus power to use in the evening or when the sun isn’t shining.

The Powerwall can also save cash by recharging itself during off-peak periods and discharging energy at times when power is more costly.

Lastly, the Powerwall can also store energy that can be used when there’s a power outage, so you don’t need to fumble around for candles or a torch. Pretty neat.

More power to the people

Tesla Powerwall and Car

Musk says the battery could help to shift people away from dirty fuel sources, but additionally that it allows power to be supplied to more remote regions with the expenses typically encountered.

Without the need for power stations and cables, it should be possible to provide electricity more cheaply and easily. Indeed, Musk says the benefits are analogous to the advantages of mobiles over landlines.

The Powerwall will come in two flavours – the first is a 10 kWh model for backup style uses, that will cost $3,500, while a 7 kWh model is for daily cycle applications and will cost $3,000. There is also a more heavy duty industrial use model, the Powerpack, which is a 100 kWh system that costs $25,000.

Pre-orders for the Powerwall are now open on the Tesla Motors website.

Is the Tesla Powerwall something that you think will catch on? Is the cost too prohibitive? Let us know in the comments below.

    Thought Lithium Ion batteries had associated fire risks. Not sure I would want one in the house
