Re: How come I can't go into EV mode sometimes?
wes878 - This is usually when I have been driving in mostly EV mode for a couple of miles and I have to speed up, then the engine comes on. Then when I slow down, (foot off the gas) the engine stays on.
You said it in your statement I highlighted in blue.
I also can drive 2 miles in the EV mode. Then the engine comes on itself, so I speed up to about 50 miles per hour if the speed limit allows it. The engine is also recharging the batteries that the EV mode just pulled down to about a 40% charge. Once they are charged back up to around 60% you might be able to go into the EV mode again. I like to try to keep my batteries just below or above the + sign.
Yes, I think your right about after running in the EV mode for a while the electric motor may get pretty hot. It may have to cool so the EV mode will work again. I have also noticed this is mostly during the hot daytime. At night when its cooler I find you can run the 2 miles in the EV mode then recharge for a few miles and then run it in EV again. In fact the car seems to get better gas mileage at night. Thats comparing it to day driving without the AC over the same road.
Now that I think of it, the batteries being drained quickly over the 2 miles could be they're very hot and have to cool. Although I never have heard the rear cooling fan come on to cool the batteries. They should also get pretty hot during the recharging process.
