nogoodbum - i believe the air intake for the HVB comes from the passenger side rear wheel well. so, if very hot outside, that could be a problem for cooling.
we have a 2016 energi. i was curious about the recharge on hills after reading some conflicting and confusing information on the internet. i took the car skiing, and on the way back down the hill it managed to charge the HVB to nearly a 1/4 charge. i did not need to pull over or turn anything on or off, i just went down hill gently using the brake. (i didn't know about the hill mode then).
we plan on driving half way across canada this summer. some of those mountains are really long climbs/descents. i'm interested to see how full the HVB can get.
in any respect, i was pleasantly surprised to see that the HVB does indeed charge up on hills.
cr08 - i'm curious to know how the battery gets stressed by being charged/discharged on the highway - do you mean heat, or something else? i was hoping to drive on the highway in EV auto mode, trying to keep it in that sweet spot of a bit of gas, a bit of electric power at the same time. i'd at least like to get some cruising along for free after we come down a large mountian.
