Grid equipment supplier ABB along with General Motors demonstrated on Tuesday an energy storage technique that combines electric car or truck battery technology including a grid-tied electric power inverter.
The two firms are building a prototype which may lead to Chevrolet Volt battery packs storing electricity, including renewable solar and wind power energy, and feeding it back to the particular grid.
The system might store electricity within the grid during times regarding low usage for use during periods of top demand, saving buyers and utilities capital.?The battery packs they can double as back-up power sources during outages plus brownouts.
Using Volt battery cells, the ABB and General motors team is developing a prototype system intended for 25-kilowatt/50-kWh applications, about the same electrical power consumption of five U.S. homes or simply small retail along with industrial facilities.
GM and ABB estimation that, during an blackout or brownout, 33 recycled Volt batteries may have enough storage capacity power up to 35 homes for about four hours.?Over time, batteries shed their storage total capacity. After seven to help 10 years, their storage devices capacity decreases to around 70% of what they had while new. Furthermore, the actual batteries are the most expensive component of plug-in electric cars. These tired electric batteries are still suitable for power company storage.
Chevrolet Volt offers an eight-year or 100,000-mile guarantee on its electric battery, GM expects these types of batteries will be able to ability the Volt to get 10 years so the earliest application likely achievable in 2021.
Our tests to date have shown the appropriateness of the GM-ABB solution in the laboratory and they have supplied valuable experience to get over the technical troubles, said Pablo Rosenfeld, ABBs program boss for Distributed Vigor Storage Medium Current Power Products. We are generating plans now for the subsequent major step C testing a larger prototype for an actual electric syndication system.
ABB has determined its existing power quality filter (PQF) inverter are often used to charge and eliminate the Volt electric battery to take full a look at the system and enable resources to reduce the cost of highest load conditions. The unit can also reduce utilities desires for power handle, protection and additional monitoring equipment. The team will test the system intended for back-up power applications.
Last twelve months, General Motors signed a definitive agreement by using ABB to identify joint investigation and development tasks that would reuse Chevrolet Volt battery solutions, which will have approximately 70 percent of existence remaining after their particular automotive use is worn out.
