I have two plug-in hybrids: 2016 Ford Fusion Energi and my 2018 Clarity
PHEV. Love both, my Clarity is my favorite. However, my Clarity fails half the time when trying to charge on public ChargePoint stations at my office. Doesn't matter whether it's cool, hot, in the sun, or in the shade, dry or wet, my Clarity fails to charge half the time at the office, regardless of charging station. The ChargePoint station initiates a charge and then soon stops with a message on its screen indicating it is waiting on vehicle. The HondaLink app says charging was interrupted. All attempts to resolve/restart charging fails (including moving the car to another station a block away). When I power on the car to move it, an error displays on the instrument cluster: "Power System: Message Plug-in Charging System Problem. Range Limited."
This problm has occurred on public charging stations intermittently since the car was new and has continued during the 6 weeks, 2,500 miles I've owned it. My 2016 Ford Fusion Energi never fails to charge at these very same charging stations. Lastly, my Clarity charges flawlessly on my ChargePoint Home L2 charger at home.
After observing this problem on the public ChargePoint station and the HondaLink app many times, I suspect there is a bug in the Clarity's
J1772 signaling protocol communications and responses. So, for now, I've given up trying to use public charging stations with my Clarity PHEV since it's such a hassle. The Clarity PHEV's excellent EV range, however, allows me to complete about 75% of my round trip commute on EV and that is a huge leap forward over what I'm able to do with my Ford Fusion Energi (I drive it 2 days/week, Clarity 3 days/week on my commute). Hoping Honda has a fix for this issue in the works. Otherwise, I love my Clarity and I'm glad I bought it.
