battery

Any feedback on charing the Clarity during very hot outside temperatures? The public charger at my workplace got recently fixed so I have the option to charge there for free during the day but here in Florida we are going through temps ranging from low 90s to low 100s during the day (it's not...

Here is an article I ran across on Tesla’s advantage in Li-ion batteries. It has a great graph on how temperature and depth of discharge affects battery longevity (# of cycles and capacity loss). The take home is that not letting your battery sit around for long periods at 100% is bad for...

Here is a link to an interesting article and video from Teslararti.com on an early 2015 Model S with over 450,000 miles. It has info on owner and warranty repair costs and battery health and replacement over a rather grueling charge regimen over the 450,000 miles driven. Since even this early...

Tesla clearly discourages its customers from charging their batteries to 100% unless you are going on a longer journey that requires the extra range. But I do not see any sort of warning/advice from Hyundai about this. I've set the charing limits to 80% (I've never tried charing to 100% yet)...

Range and battery pack capacity are closely related (what a surprise). But look how far the Tesla Roadster concept has gone!

Another important thing to mention is the inverse relationship between battery pack size and efficiency. It is more visible among high-end EVs.

Since I purchased the Clarity Touring 12/05/18 the charge always stops at 99%. I switched from a 16 amp 240 V charging station to a 40 amp 240 V one two weeks ago and I'm still getting 99% of a full charge. Probably not a big deal to a lot of people but it bothers me. I recently disconnected...

In the last few days we have heard about a Tesla patent by professor Jeff Dahn to make batteries cheaper and more robust. Some time ago Elon was suggesting that Tesla would achieve a significant battery improvement including about 30% to 60% increase in energy density sometime in early 2019. And...

https://www.cnn.com/2018/12/13/business/electric-cars-charge-bmw-porsche/index.html I wonder how long it will be before battery technology matures to make this feasible. The line I found most interesting was at the end, an effect I hadn't considered: "A service station with 20 charging...

Does anyone know something about this?... https://www.straitstimes.com/singapore/ntu-scientists-invention-can-restore-phones-battery-life

Hello; I am typically driving 80km( 50 mile) back and forth from work return trip and thus I am generally full on normal summer days and when I return , my battery is empty depending on weather. Now that winter is coming and I am in Canada , so temperature has started dropping here , so now I...

Below is an estimate of the CO2 emissions in metric tons saved by the Clarity PHEV over the highly efficient 2019 Honda Insight. I have several disclaimers, notes, and cautions: This is not a full Life Cycle Analysis study (LCA) that covers all environmental impacts, but rather just an...

This looks like an interesting option for older Leafs: https://fenix.systems/news/fenix-news/2018/09/25/press-release-announcing-c5-leaf-pack-and-baas-products From a facebook post, John Bysigner claimed that "Yes there will be thermal management, the charging experience will be identical to...

I learned a lot by reading this article... https://cleantechnica.com/2018/08/26/the-secret-life-of-an-ev-battery/ Some highlights: If the car is sitting in the hot weather a lot (unused), better to have it at low-mid charge level than fully charged To maximize life, the battery management...

I have noticed that my Clarity will on occasion start to use gas to charge my battery, even when the battery is adequately full, and I have NOT switched on HV mode. Has anyone else noticed this? Is there a way to "force" the car back to EV mode? I have switched HV mode on and off when this...

As I found in the docs shared by @Atkinson and posted previously, both our batteries are supposed to be tested per the 13 page Pre Delivery Inspection Sevice Bulletin 17-093 dated 1/25/18. I went back to my dealer and had them measure my Li-ion Battery Pack Capacity signal. As you can see, at 6...

I looked on the forum for any mention of this, but didn’t see anything... I didn’t drive my Clarity for 5 days while on vacation and the battery (that starts my car and runs the accessories), went from completely charged to 0%. I took it to the dealer because I had not left anything on, like a...

Thanks to @Atkinson for sending me a treasure trove of docs he found on Honda Tech. The best of the lot is the attached Pre Delivery Inspection (SB 17-093) that lists a lot of info not previously sourced on the forum. Here are some of the highlights: 1. We finally have a documented metric on...
