👉 Bidirektionales Laden wird zu einem normalen Bestandteil der Nutzung von Elektrofahrzeugen. Es gibt viel Unterstützung außerhalb der Automobilindustrie, um #V2G / #V2H zu ermöglichen.
AC vs. DC on bidirectional charging 25 months and >100,000 readers after I posted about AC vs. DC Bidi, it's time for an update. Admittedly, the last 25 months have been like a Luis De Funes film, and not just because of their French origins. What I have experienced over the last two years can best be described as ‘exciting’ in a soothing way. ▶️ Highlights: 👉 Instead of simplifying and standardising the grid codes, they have become more difficult to comply with and have not been completely harmonised across Europe. The EU under the lead of ACER redefined standards on charging and gave a guideline for discharging also. DCC & RFG 2.0 (V1G & V2G). 👉 Demonstration of AC-BiDi EU pilot projects with solar inverters in the boot of a vehicle. Admittedly a bit bulky, but, yes that's future reality, a OBC needs to works as a solar inverter in future, beside that he additionally needs to be galvanic isolated. 👉 Even the last person in the industry must now have realised (okay, maybe not Elon, but he's distracted at the moment) that V2L is not suitable for connecting a vehicle to the power grid. 👉 In Germany, the government is being blamed for ‘Kleinstaaterei in grid codes’ for not approving BiDi. Sorry, but that's complete BS and completely dubious. ▶️ Now for the positive: 👉 Bidirectional charging will become a normal part of electric vehicle use in future. I see a lot of support outside the automotive industry for enabling V2G 👉 The grid codes and general rules for electric vehicles on the grid are set by the EU and serve as guidelines for future developments. There are no exceptions for AC BiDi. Whining and complaining, as well as the use of voodoo dolls, will not change that. Good news for the OEM's they can start no scribbling roadmaps and spec-sheets. 👉 The increasing demand for flexibility in the energy market and variable grid fees make BiDi a valid business case, V2H & V2G. Although it won't be several thousand € a year, but it could be 500 to 1,000€/a. ▶️ What happens now: 👉 If the industry continues to collaborate like one DCC and RFG 2.0, we will have specifications for AC BiDi defined by mid-2027. It is not yet entirely clear which components and functions will be installed and implemented in the vehicle and which in the AC-BiDi Wallbox. 👉 Car manufacturer are implementing BiDi with ISO 15118-20, TLS 1.3 & OCPP 2.1. 👉 Now that it is clear how the hardware will be specified from 2028 onwards, it will be important to focus on the software. However, this also means a lot of work in terms of cyber security and interoperability with other energy assets. ⏭️ I hope that the next two years will bring fewer religious discussions with less empty rhetoric. It didn't help at all, quite the contrary. 🙏 Thank you to everyone who engaged in open discussions with us. 🙏 #ambibox #ambicharge #Volkswagen #VW #Seat #Skoda #BMW #TESLA #Mercedes #Nissan #Honda #Stellantis #Porsche #BYD #Maxus #MG #Zeekr #FORD #Toyota | 91 comments on LinkedIn
