能源网和大众合作开发区块链，用于储能的电动汽车电池

昨天，区块链联盟能源网宣布与大众创新集团合作，探索整合电动汽车(EV)充电点。这个想法是利用电动汽车电池储存剩余的可再生能源，当能源需求超过供应时，这些可再生能源可以释放到主电网。

“电动汽车端到端无缝参与电力市场”是双方合作的目标。参与项目将包括美国电气化(更确切地说，是美国的公钥基础设施)。

Electrify America是大众汽车(Volkswagen)旗下子公司，在美国拥有500多个充电站。该公司于2016年成立，作为大众柴油丑闻和解协议的一部分。该公司承诺投资20亿美元建设零排放汽车充电基础设施。

虽然电动汽车有助于减少排放，但电池还能带来另一种环境效益。随着太阳能电池板和风力发电场等分布式能源(der)与电网的整合程度越来越高，电力来源也变得越来越不一致。这是因为你不能像控制发电机那样控制风和太阳的开关。我们需要的是通过额外的能量储存和电动汽车电池来平衡电网的能力。

Energy Web首席商务官Jesse Morris解释说:“通过这次合作，我们希望加速电动汽车的发展，为电动汽车客户带来更多价值。”“一种方法是让电动汽车更容易无缝地进入能源市场。如果我们成功了，当一辆电动汽车从经销商那里出来的那一刻，它就会完全融入到该地区的能源系统中。然后，客户就可以为他们的电动汽车付费，以近乎实时的方式帮助平衡电网。”

随着电动汽车越来越成为主流，充电要求本身也可能增加电网的不一致负荷，特别是如果每个人都通宵充电的话。彭博新能源财经(Bloomberg New Energy Finance)预测，到2040年，销量将从2020年的170万辆升至5400万辆。管理充电的时间也会有所帮助。虽然公告中没有提到，但我们注意到，美国电气化公司正在推出一个家庭充电解决方案，homeestate，这应该有助于解决这个问题。

大众集团创新(Volkswagen Group Innovation)项目负责人马文•施罗德(Marvin Schroeder)表示:“我们热衷于探索区块链技术为智能充电应用带来的可能性，以及它如何对生态足迹产生积极影响，从而为我们的客户增加价值。”

2020年，大众推出了全电动ID.3，随后将推出ID.4 SUV。该集团打算在未来五年内投资350亿欧元在电动交通领域，并在未来十年内推出大约70款全电动车型。

与此同时，能源网已与奥地利电网合作，尝试将DERs与电网整合。

大众的项目将使用能源网的技术和电动汽车充电标准，如ISO 15118 Plug & Charge标准。

5个月前，区块链移动联盟MOBI推出了电动汽车电网集成(EVGI)标准，由本田和通用汽车牵头。

许多汽车制造商正在探索使用电动汽车电池来存储能量。然而，有些是局部的，而不是网格集成。丰田去年在日本启动了一个项目。在加州，欧米茄网格正在与EDF合作。在欧洲，四家主要的电力公司都是Equigy的一部分，旨在平衡电网。公用事业公司TenneT与宝马和尼桑就双向充电进行了合作。此外，Terna还与菲亚特克莱斯勒(Fiat Chrysler)建立了一个虚拟发电厂(VPP)，为车队提供能源。

Yesterday blockchain alliance Energy Web announced a partnership with Volkswagen Group Innovation to explore integrating electric vehicle (EV) charging points. The idea is to use EV batteries to store surplus renewable energy, which can then be released into the main grid when energy demand exceeds supply.

“Seamless end-to-end electricity market participation for electric vehicles” is the goal of the partnership. Participation will include Electrify America (or rather its public key infrastructure). 

Electrify America is a Volkswagen (VW) subsidiary with more than 500 charging sites in the U.S., set up by VW in 2016 as part of its settlement over the VW Diesel scandal. The company committed to investing $2 billion in Zero Emission Vehicle charging infrastructure.

While EVs help to cut emissions, a second set of environmental benefits can be gained from the batteries. As distributed energy resources (DERs) such as solar panels and wind farms become more integrated with the electricity grid, power sources become less consistent. That’s because you can’t switch the wind or sun on and off in the same way you can with generators. What’s needed is the ability to balance the grid by having additional energy storage and EV batteries fit the bill.

“With this partnership, we want to accelerate electric mobility and deliver even more value to EV customers,” explained Jesse Morris, chief commercial officer of Energy Web. “One way is to make it easy for EVs to seamlessly participate in energy markets. If we’re successful, the moment an EV rolls off the lot of a dealership that car will be fully integrated into the energy system in the area. Customers can then be paid for their EVs to help balance the grid in near real-time.”

As EVs become more mainstream, the charging requirements themselves could also add to the grid’s inconsistent load, especially if everyone recharges overnight. Bloomberg New Energy Finance forecasts sales rising from 1.7 million in 2020 to 54 million by 2040. Managing the timing of the charging could also help. While not mentioned in the announcement, we note that Electrify America is launching a home charging solution, Homestation, which should help to address this issue.

“We are keen to explore the possibilities that blockchain technology can have for smart charging applications and how this can have a positive effect on the ecological footprint and thus an increase in value for our customers,” said Marvin Schroeder, the project leader at Volkswagen Group Innovation.

In 2020 VW released the all-electric ID.3 with the ID.4 SUV to follow soon. The group intends to invest
