14 hours to charge

If I remember correctly the time to charges was advertised as 10 to 12 hours. I routinely charger for 14 hours. Has anyone else experienced this long charge time?

I believe there is some research that says colder temps can indeed lengthen charge times due to how the battery chemistry reacts.

Hope this helps.

Good luck!

As someone else posted, low temps can have a negative effect even on charging. Also, if you don't have a dedicated socket of at least 50 amps, that could also be the reason it takes longer to charge.

I live in SoCal so my temps rarely get below 50. Seems like a long time to me.

Nothing to fret over. Others have reported 13 plus hours to charge as well.

My advice is to drive the car a few months to get a feel for how it operates.

You can get an aftermarket 120v charger that puts out more amps and will charge a bit faster.

I live in southern California and my Clarity consistently took around 14 hours to charge with 120 volts. Now with my level 2 charger at 240 volts, it consistently reaches full charge between 2 and 2 1/2 hours. Both charges are with a depleted battery.

Amps are controlled by the source. You can't put more through the cord than are coming into it. Honda recommends a dedicated 50amp circuit for 120v. It is true, more amps will make for faster charging.

Level 2 Charging

Actually the amount of current and hence energy that can be used in charging a Clarity (or other EV type vehicle) is dependent on the "charge cord" used. Of course, the manufacturer's use of the word "level" merely refers to the *voltage* at which charging occurs. A Level 1 charge (120 volt ac) cord comes with the car. Even though I bot a new Clarity, I'm not a fan of paying more than I think something's worth, such as the Honda Clarity Level 2 (240 volt ac) charging cable (at approx $ 450).

So I opted to purchase a much less expensive (Ebay) Level 2 charging cable ($ 150). It's a 240 volt charge cable that only allows a 16 amp charge rate (as opposed to Honda's cable that allows 32 amps), and it fully charges the car in about 4 hrs instead of Honda's cable full charge time of 2 hrs. I did have a dedicated circuit installation made for this cable. But here again, I paid less for the 20 amp wire, and circuit breaker instead of 40 or 50 amp wire and circuit breaker that would have been required had I used/paid for Honda's charge cable.

I don't know about you but 4 hours to fully charge car works for me just about as good as a 2 hr full charge time.

I live in middle Georgia.
In the summer, my L1 charge times have been 14-15 hours due to the heat.
In the winter, my L1 charge times have been 13.5-14.5 hours due to the cold.
In fall (and assuming spring), my L1 charge time has been around 12-13 hours.

I primarily charge with an L2 charger and regardless of season, a full charge takes around 2 hours because of both the higher charging current and the fact that it can use some of that energy to heat/cool the batteries to optimize charging temperature. (at least that's what I think happens... The cooling fan runs faster on L2 than L1 when it's hot)
