Does anyone know if it's 100% safe to force EV mode ( by pressing the ev button) and repeatedly accelerate out of EV mode quickely? The reason I ask is because where I live people on the highway accelerate quickely. I try to stay in the eco EV range up to 15 mph, but when I do someone is up my rear end. However, when I force EV mode I can accelerate up to 25mph with the flow of traffic. Then I use the ICE to accelerate up to 60mph. My concern with forcing EV mode and repeatedly accelerating past 25 mph is it will be harder ( lessen the life ) on the battery or the transmission or the electric motors or the inverter. And yes I know the electricity has to come from the ICE, but when I force EV I can get 2-4 mpg more. Now if I was staying under 45mph would not force the EV and save the battery for crusing at 45mph. However at 60mph I hardly every use the battery. So, to me it seems more prudent to force EV past 25mph and then use the ICE up to 60mph. However I do not want to force EV if it shortens the life of anything.
