I am new to this forum and have a question. I have a 2018 Honda Clarity PHEV Touring purchased November 2018. I have put this question to my local Honda dealer and I have called Honda Technical Support and none have provided me a satisfactory answer. The Honda Clarity PHEV manual (page 466) states you should plug in the vehicle at the end of a day's driving so it can recharge completely before the next time the vehicle is used again. When I do this of course all the read outs indicate the vehicle accepts a full charge if left to charge undisturbed for the appropriate amount of time. However, in reading about EV vehicles there seems to be wide consensus you should never charge the battery bank consistently to 100% or it will lessen the life of the battery; many EV’s even restrict charging after 80 percent full. However, when I check for information about the Clarity PHEV and the Toyota Prius Prime for example, no such mention is made of restricting the charge to 100% at any charge interval. However, all other devices using lithium-ion batteries these days are generally recommending to confine maximum routine charge levels to 80 percent. I just don’t understand what makes the lithium-ion batteries in the Honda Clarity or the Prius Prime different from other EV’s, or all like batteries. Anyone got any information to clear up this seeming discrepancy?
