EU project Stardust<\/a>. \u201cIts car park is used by the municipality\u2019s electric cars. Since these vehicles are always out on a regular schedule, they can be used as additional storage for the remaining time,\u201d said Carlos Larrea, Engineering Manager at BeePlanet.<\/p>\n\u201cWhen it detects that the electric cars are parked and connected to the V2G chargers, it can decide to charge them when it\u2019s sunny, take advantage of the solar energy production surplus, and discharge them when it rains,\u201d added Faisal Bouchotrouch, technical and innovation manager at Spanish technology centre, CENER, who helped develop the process.<\/p>\n
\u201cThe EMS reads the weather forecast for the four days ahead. Then, thanks to a smart algorithm, it calculates the best possible configuration every hour and manages the system accordingly. Its latest version considers even more complex parameters and adapts energy management to fluctuating electricity prices.\u201d<\/p>\n
Assessing the performance of repurposed batteries<\/h3>\n \u201cThe configuration that we have tested for the Stardust project has allowed us to cut energy costs by up to 30%, but with more solar panels, you can achieve even bigger savings,\u201d said Bouchotrouch.<\/p>\n
This success has also been made possible by the surprising performances of the electric car batteries repurposed by BeePlanet. \u201cThey perform much better than expected, proving that automotive batteries can have a second life,\u201d stated Larrea.<\/p>\n
\u201cMoreover, since they are designed for very demanding conditions, with strong consumption peaks whenever one accelerates can extend their life by ten to 15 years.\u201d WEF identified V2G systems among the most impactful drivers of a sustainable electric car battery value chain and recommended that manufacturers, the automotive industry, and utilities work together to make them possible on a large scale.<\/p>\n
\u201cThe process will be adopted into EU legislation next year\u201d<\/h3>\n Grid-connected batteries will be the dominant flexibility and stability solution by 2030. However, the existing legislation is mainly outdated and does not meet the need for a sustainable approach.<\/p>\n
\u201cUnfortunately, the situation is quite simple: the only European battery directive dates back to 2006, before the electric era, and it doesn\u2019t even contain a definition of an electric vehicle battery,\u201d Tedesco explained.<\/p>\n
Recently, the European Council adopted a general approach to revise the directive and transform it into a proper regulation, aiming at setting up a circular economy sector and targeting all stages of the life cycle of electric car batteries, from design to waste treatment.<\/p>\n
\u201cNegotiators could have been much more ambitious on reuse, but it\u2019s an encouraging step forward. So far, the proposal aims to reach 80% of lithium recovery by 2030, but we insist on at least 90%, as battery manufacturers and recyclers suggested.<\/p>\n
\u201cSet to replace the 2006 directive, the new EU regulation is now in its final stages and should be adopted next year,\u201d Tedesco concluded.<\/p>\n","protected":false},"excerpt":{"rendered":"
