United States. A local firm developed a battery for electric vehicles capable of working at high temperatures, which could minimize the heating or cooling needs of the system.
This advance would reduce the costs of electric car batteries or other types, as it could overcome the limitations of lead acid, standard lithium-ion and other advanced batteries.
Tests performed on this battery showed that it is capable of retaining more than 90% of its initial capacity at 45 degrees Celsius and can also work at -30 degrees Celsius.
John Voelcker, an analyst at Green Car Reports, commented that current electric cars have coolant pumping systems to remove heat from the batteries, but that this alternative "would reduce the weight, complexity and cost of future electric vehicles, lowering their price and making them more competitive in the market."
The name of the battery is Nanophosphate EXT and was designed by the company A123 Systems.
