battery

Hey everyone, I’m looking for some advice on my 2022 Accord Hybrid and its high-voltage (HV) battery. Here’s the background: I purchased the car wrecked at auction. It was running fine when I received it. During welding (with the 12V battery disconnected), the process ended up frying the...

hi, i got 2018 Touring with 88K on it. just got there 2 code on my ODBii reader after the engine light came on. its my 1st real issue with car. The Honda P1DC7 code is a trouble code related to high voltage battery deterioration. It is a diagnostic trouble code (DTC) stored in the battery...

Hi. Im new to the inside evs forum. I did a 72 Beetle conversion back in 2015, and have put on about 30K miles in 9 years commuting to work. It has 40 200 AmpHour LFP prismatic cells wired in series. Now, after 9 years in the Phoenix heat, those cells are swelling and cracking, so its time...

Crowdsourcing information - I will be traveling for ~3 weeks, longest trip since getting my ‘23 SE. Is it necessary (or recommended) to hook up a battery maintainer (for example the NOCO genius model) for the 12V battery? The owners manual recommends not leaving the EV charger plugged in or...

Hello, I am wondering if it is possible to charge a battery system from a small solar panel over time and then charging my EV truck off that battery? Buying a big solar system in my area is cost prohibitive and would then make it more expensive to drive and charge my truck then just a regular...

GM has started the Battery Replacements for the Water Related issue as seen by these photos here: https://www.hummerchat.com/threads/gmc-hummer-ev-battery-pack-replacements-under-way.2353/post-23087

From https://www.eurekalert.org/news-releases/980626 “With further development, we expect our new design for the lithium-air battery to also reach a record energy density of 1200 watt-hours per kilogram,” said Curtiss. “That is nearly four times better than lithium-ion batteries.” If (or when)...

It appears that GM has made design/production changes for the Battery Enclosure in the Hummer EV to resolve a Urethane Seal not properly bonding and allowing moisture/water in caused by under-cured electrocoating on the battery pack. This will impact around 700 of the first Hummer EVs produced...

OK, guess it's time to replace the 12v battery in my 2019 Kone EV. Is there anything "special" about this battery, i.e. will I be OK going to Walmart, or Costco, or any other store that sells auto batteries? Are there any specs that I should make sure the new battery conforms? TIA

Hi everyone! My name is Ryan, I've had my 2017 Premier for about 2 years. I am working on a project with Out of Spec Reviews (https://www.youtube.com/c/OutofSpecReviews), we want to compare the range between a Bolt that received the recall battery replacement and one that has not. We're looking...

I have an AAWireless Android Auto adapter so I can use the Android Auto app wirelessly in the Ioniq 5. It works well. The adapter has to be plugged into the same USB port as the cable from the phone if I were using the app wired, that’s the port on the floor under the dash. When I turn the car...

Calling all inventors! We all know that not having a rear windshield wiper on the Ioniq 5 is a big omission by Hyundai but does anyone know of an available portable wiper that may work? Amazon has so called portable wipers for UTVs like a Polaris Ranger but they look like they need to clip onto...

Hello guys. Just curious if anyone here is keeping track of the battery's soh along the years. If so, how's your batteries holding and how many kms/miles have you done? I've used car scanner to get some info. After 2 years and +35000 km, it says that soh is on 96%. I'm not sure if there's...

Hello, looking for some help here. Wife was driving the car a couple days ago in below 0 F temps when a series of warning indicators flashed. "CRITICAL FAILURE DETECTED, STOP DRIVING WHEN SAFE", "12 Volt Battery Charging System Problem", "Low Battery Charge. Power Reduced" and a red battery icon...

A groundbreaking new battery technology is being developed and tested to enhance the performance of an electric vehicle. By placing this new battery technology into a Tesla Model S P90D test vehicle, to extend the range over 700 miles, and battery life of up to 100 years, this will replace...

So, this is a general question for everyone. I'm curious how long the battery in a plug in car will last? Batteries are good for only so many charges and going from 0-100% is the worst thing to do for a Lion battery. So is a plug-in a useful product? I would imagine that they are used 0-100%...

I'm seeing a lot on the internet about CCCV charging, but when I look at car batteries most curves don't seem to follow CCCV. Is this because CCCV is only for longevity and car batteries are manufactured in between safe margins? Thanks in advance :)

Our Hyundai Kona recall 200 to replace the high-voltage battery was scheduled for a local dealer today September 9th 2021. This did not go so well as after we met with the adviser at 8 a.m. around noon they informed us that they were not certified to work on electric vehicles and did not have...

16,000 miles SoC (State of Charge): 100% charged overnight every day, during the daytime, I try to maintain around 20% to 60% all the time Charging cycles: every day, for one year, 365 cycles. Most of the time, from 10% to 100% Driving: 90% EV, 10% hybrid. Used a lot of A/C, I always turn on A/C...

I did two Videos about the software updates related to the recall. The first one lists the software updates and changes. (link at the end of this video) In this second one I am testing the DC quick charge speed and highlight the changes to it. I hope this shines some light on it:
