You plugged in before bed and expected a full pack. Morning still shows last night’s same percent. In Los Angeles County that miss usually isn’t a fried charger. It’s a schedule, a sleep glitch, or a shared post that never started.
Older housing is why so many overnight charges sit on a shared post
Census housing age is the local reason this search is so common here. The City of Los Angeles has 71.0% of housing built before 1980. That’s U.S. Census Bureau ACS 2019-2023. East Los Angeles is 86.2%. Whittier is 88.9%. Lakewood is 88.8%. Culver City is 85.5%. West Hollywood is 80.5%. Long Beach is 79.6%.
Those buildings went up for gas cars and ceiling lights. They weren’t designed around a private Level 2 stall in every garage. A lot of overnight charging here happens on a shared public post. Sometimes it’s a cord in a tight carport. You don’t set that timer the way a single-family garage does.
Newer tracts tell a different story. Palmdale’s pre-1980 share is 19.7%. Santa Clarita’s is 30.4%. Stevenson Ranch’s is 3.4%. Owners there more often charge on gear they programmed themselves. The overnight miss still happens. The apartment-and-lot version just adds extra ways for the session to never begin.
An old panel can block a home unit. Read old electrical panel, no home charger for the backup path.
Your car may have been waiting for an off-peak window
Most EVs let you pick a departure time or an off-peak window. The car holds the session. It doesn’t pull power the second the handle clicks.
That setting is common here because utilities price overnight power differently from daytime power. LADWP serves the City of Los Angeles. It publishes a dedicated EV Time-of-Use rate that needs a separate EV meter. Confirm the current plan rules on ladwp.com before you change a setting. Southern California Edison serves most of the rest of the county. It publishes EV rate plans on sce.com.
Many SCE cities buy generation through Clean Power Alliance. That list includes Santa Monica, West Hollywood, and Culver City. Redondo Beach and unincorporated Los Angeles County are on it too. SCE still delivers the power and reads the meter. Your charge schedule still lives in the car. It doesn’t live on the CPA line item.
The trap is a window you set once and never opened again. Your shift moved earlier. You plugged in after ten. An app update restored a default. The window now starts after you’ve already left. Open the app or the center screen. Look for scheduled charging, charge on departure, or off-peak charging. If that window never opened while you slept, the percent didn’t move. The hardware didn’t fail.
The pack may already have been at your limit
Owners often cap the pack below full and forget after a short day. If you came home at the cap, overnight charging had nothing to add. Check the set charge limit before you hunt a fault.
Sleep can block a window that was otherwise fine
Plug in at dinner with a window after midnight. Some cars then drop into a low-power sleep. They don’t always wake cleanly when the clock hits the window.
Shared lot posts make this worse because the car sits for hours before the window. The computer may never fully wake even if the post looks normal.
Wake it on purpose before you assume a broken stall. Open and close a door. Unlock with the fob. Start climate from the app. If charging begins a few minutes later, sleep was the issue. You don’t need new hardware yet.
A shared post fails in ways a garage wallbox doesn’t
A home wallbox is one device you control. A shared post isn’t. The handle can look seated and still miss the handshake. The kiosk can show green while the car shows nothing. Another driver can end the session. The stall can sit in a fault left by the last car.
The post can say connected while the percent never moved. Use the checks in public charger says connected but it’s not charging. Reseat the handle until it clicks. Try another stall if one is free. Don’t treat a session that never started as an empty pack.
Coast lots in Santa Monica and Redondo Beach see this after late returns. East Los Angeles, Alhambra, and El Monte see the same miss on older shared posts. The plug was in. The session never ran.
What you see, and the first check
| What you see | Likely cause | First check |
|---|---|---|
| Same percent as last night, cable looks seated | Scheduled window later than you thought | App or dash: departure time or off-peak window |
| Unplug and replug, then it starts | Sleep state before the window | Open a door or start climate from the app |
| Charge stopped in the middle of the night | Charge limit already hit, or a real cut | Confirm the set charge limit first |
| Green light on the post, nothing on the car | Loose plug or a handshake fault | Reseat the cable and listen for the click |
| Breaker or GFCI tripped | Circuit lost power, not a pack fault | Follow the breaker-tripping guide |
| Car plugged in, screens dark, doors slow | Weak 12V, not an empty drive pack | See when an EV 12V dies |
When the window was open and still nothing moved
Confirm the schedule was live all night. Then rule out the simple hardware misses.
The plug never fully latched. Tension on a short cable can ease the handle out. Push it in until you hear or feel the latch.
The circuit went dark. A garage GFCI or a lot panel can trip after you go inside. Reset once. If it trips again, stop and call a licensed electrician.
A fault light on the EVSE usually means the box needs service. Solid or blinking red isn’t a schedule issue.
A weak 12-volt battery can drop a session that already started. That’s a 12V problem, not an empty pack.
Morning, low range, and you still have to leave
Troubleshooting is fine when you have time. A commute isn’t that morning. Don’t gamble on a percent that never moved.
Charge Pro LA is a referral line. We match stranded drivers with independent local mobile rescue operators. We don’t own trucks or send technicians. The operators we connect you with bring a 240V Level 2 source to the car. Native NACS for Teslas. CCS or J1772 adapters for other brands. They typically add 10 to 20 miles of range in 15 to 30 minutes of charging. That’s charging time, not an arrival time. The operator quotes you before starting and bills you directly.
If the pack is already tight, use our guide on running low before you stall. For a boost in place, start with mobile EV charging.
Frequently asked questions
Why did the car say charging if the percent never moved?
Usually the scheduled window hadn’t opened yet. Or the session sat at your charge limit. Check the app schedule and the set limit before you blame the stall.
Does sitting plugged in with no charge hurt the pack?
No. An inactive session doesn’t stress the high-voltage battery. The software is choosing not to draw power. That’s a schedule, a sleep state, or a limit already met.
What if I have to leave and almost nothing charged?
Don’t roll out on a guess. Call (858) 925-5546. We’ll connect you with a local operator. They can bring a Level 2 boost to where you’re parked. They quote before they start.
