Why Won't My EV Charge Past 80%

Your EV stops charging at exactly 80% every time and won’t go higher, no matter how long you leave it plugged in. Or you set the charge limit to 90% and it still stops at 80%. This guide explains exactly why this happens and how to change it, including when 80% is actually the right answer.

This guide belongs to our EV charging problems section. For the full overview, see EV Charging Troubleshooting.

The Short Answer

An EV that won’t charge past 80% has its charge limit set to 80% in the car’s settings or app. This is the factory default on most EVs, it’s a battery longevity feature, not a problem. Raise the charge limit in the car’s settings to whatever percentage you want. The exception is the Chevy Bolt recall, which temporarily hard-limited charging to 80% until battery replacement.

Why Your EV Stops at 80%

Reason 1: The charge limit is set to 80% (most common)

Every major EV has a configurable charge limit, a maximum state of charge the car will charge to and stop. The factory default on most EVs is 80% because lithium-ion cells experience noticeably more stress when held at high states of charge. Charging to 80% daily and only going to 100% before long trips is the recommended practice for maximizing battery longevity. The car is working exactly as configured.

Reason 2: A recall or safety update locked charging at 80%

The Chevy Bolt EV and EUV recall (2021–2023) included a mandatory software update that limited charging to 80% as a precautionary safety measure while GM developed a fix for the battery fire risk. Once the recall battery replacement was completed at the dealer, the 80% limit was removed. If you have a Bolt that was recalled and never brought in, the 80% limit will remain until the recall is addressed.

Reason 3: Smart charging feature scheduled the stop

Some EVs have a “smart charging” or “predictive charging” feature that targets specific charge levels based on your departure time and typical trip length. If the car calculates you only need 80% for your next trip, it may stop there even if the charge limit is set higher. Check whether this feature is active on your car and whether it’s overriding your manual charge limit setting.

Reason 4: A software bug

Some software versions have a documented bug where the charge limit reverts to 80% or where the car stops charging at 80% regardless of the setting. Check your car’s owner forum for your specific software version to see if this is a known issue. It’s typically resolved in the next OTA update.

How to Charge Past 80%

By brand: where to change the charge limit

Tesla: Touch the charging port icon on the map screen → Charge Limit → drag slider to desired % (up to 100%)
Hyundai Ioniq 5: Vehicle Settings → EV Settings → Charging → AC Charge Limit → adjust
Kia EV6: EV menu → Charging Settings → AC Charge Limit → adjust
Chevy Bolt: Energy → Charging → Hilltop Reserve / Charge Limit → set to 100%
Ford Mustang Mach-E / F-150 Lightning: FordPass app → Charging → Charge Limit → adjust, or in car SYNC settings
Nissan Leaf: Long press the charge button to toggle between 80% and 100% charging targets
Rivian R1T/R1S: Vehicle settings → Charging → Set daily max → adjust
VW ID.4: Settings → Charging → Target charge level → adjust
BMW i4: My BMW app or charging settings on the iDrive screen → Target charge level
Audi e-tron: MMI → Vehicle → Charging → Target charge level

When to charge to 100%

Charging to 100% is fine occasionally and recommended before long trips. Doing it every night noticeably increases long-term cell stress and accelerates degradation. The sweet spot is 80% for daily use, 100% only when you need maximum range for a specific trip. Most EV manufacturers recommend this approach in their owner’s manuals.

What If You Want to Always Charge to 80%?

Then leave it there. 80% is the right daily charge target for most EV owners and maximizes battery longevity. The 20% buffer above the daily charge also gives the BMS room to balance cells during charging, which helps maintain accuracy of the SOC display and reduces cell imbalance over time. Only change it to a higher percentage when you actually need the extra range.

Chevy Bolt Recall: Special Case

If you have a Chevy Bolt EV (2017–2023) or EUV that was under the battery recall and haven’t had the battery replaced yet, your car is limited to 80% charging by a mandatory software update. The only way to remove this limit is to complete the recall battery replacement at a GM dealer. This service is free under the recall and includes a new battery module. After replacement, you can charge to up to 100%.

FAQs

Is it bad to charge to 100% every day?

Charging to 100% every night and leaving the car at 100% for extended periods does accelerate long-term degradation more than keeping it at 80%. Studies from Recurrent and other battery research organizations suggest daily 100% charging increases annual capacity loss by approximately 1–3% compared to daily 80% charging. The effect is real but modest, most owners won’t notice the difference in the first 5 years. For long-term battery health, 80% daily is the better habit.

My charge limit is set to 90% but the car stops at 80%: what’s wrong?

This is a classic sign of a software bug where the charge limit isn’t being applied correctly. Try changing the limit to 100%, saving, and then changing it back to 90%. If the car still stops at 80%, check for a pending software update and install it. If the problem persists after an update, contact the manufacturer’s support line, this is a documented issue on some firmware versions of multiple brands.

Bottom Line

An EV not charging past 80% is almost always the charge limit being set to 80%, which is the factory default and recommended daily target. Change the charge limit in your car’s settings or app to whatever percentage you need. For daily commuting, 80% is optimal. For long trips, set it to 100% the night before. If the car stops at 80% despite a higher setting, check for a Chevy Bolt recall status or a software bug, and install any pending OTA updates to resolve it.
