"But wouldn't I suffer from the negative impact of #vehicletoX on my EV battery's health?" Only if you plan to drive your car for more than a million kilometers. I really enjoyed the insightful and compelling presentation by Prof. Dirk Uwe Sauer at the Vehicle-to-Grid conference in Münster yesterday - see my favorite slide below. In a nutshell, the cycle-life of an EV battery will typically get you much, much further than you will usually want to drive your car - using some of these cycles for V2X applications such as optimizing your PV self-consumption at home therefore does not play a role. Or, in other words, the wheels of your car have probably fallen off long before your battery is even close to reaching the end of its life. Of course, battery ageing is a complex topic and depends on many operational (e.g., c rate, DoD, SoC) and ambient factors (e.g., temperature). But Prof. Sauer's back of the envelope calculation shows that the impact on battery health is not the big challenge to focus on. Regulatory issues and sufficient economic viability are the nuts to crack here. #alternativeenergy #sustainability #energy #energytransition #automotiveindustry #electricvehicles #transportation #electricvehicle #ev #emobility #batteries #energystorage #battery
Thanks for that valuable insight. Vehicle batteries indeed last much longer than most people think. Quite often the OEM warranty of 8 years is understood as the expiry date for the battery. But that‘s not the case. Vehicle batteries will last an entire vehicle life for most people’s driving profiles.
Yaniv Giat Uri Furberg look at this. Very interesting data!
Excellent facts!

6moRight now, it’s a lot more expensive to buy bidirectional chargers and only a few EVs support V2G. Not sure if the extra cost can be covered by “peak shaving” or other usage. Do you may have an indication on that?
