Last February we learned of the renewed intention of Tesla’s Elon Musk company was preparing its assault on the supply of electricity at home thanks to specific batteries for our homes . They came the power wall Tesla . And we analyze the impact and cost that such alternative could have in our homes and in the type of use that could make of that energy, but these calculations are changing rapidly.
A study recently published in the journal Nature Climate Change study has revealed that the cost of lithium-ion batteries for electric vehicles is down significantly , and that will also affect the cost of production and sale of household batteries. They have exceeded expectations so that the potential arrival of batteries to our home and our car at a competitive cost is now much closer than previously thought.
Competitive “Almost” with combustion cars
Several companies are already investing in this market, and not only those oriented to the production of batteries for electric cars. The construction of the “super factory” Tesla in Nevada will not only boost the drop in prices , which was mainly due to the ” learning rate “or as the study authors explain,” cost reduction following a doubling cumulative production . ” Improve processes, materials improve, and margin improvement achieved is remarkable in these early iterations of this promising segment.
Björn Nykvist and Måns Nilsson, who work in the Stockholm Environment Institute, have conducted an analysis of the estimated electric vehicle batteries through the information in reports of agencies, consultants and industry analysts costs, other than their own estimates manufacturers of such batteries. According to his data, the cost has dropped from $ 1,000 per kWh in 2007 to $ 450 per kWh in 2014. But beware, because if you just take into account the manufacturers of batteries for electric vehicles, the cost drops to 300 dollars.
In the opinion of these experts, ” is I understand that the cost of batteries has to fall below $ 150 per kWh for these electric vehicles based on batteries are competitive with combustion vehicles “Because research and development of such batteries is growing and evolving particularly quickly, hopefully not too late in this barrier reached as much as it seemed. In fact, the researchers say, ” be around 200-250 dollars per kWh by 2020 is likely “.
