The cable clicked in last night. The port light looked fine. The percentage this morning is the same number you went to sleep with. In Tampa Bay, start with the clock on the charger. Then check the outlet, the heat, and the 12-volt. A ruined wall box sits further down the list.
Start with the clock, not the hardware
Overnight charging here follows utility windows, not just a seated plug.
Duke Energy Florida serves Pinellas County and much of Pasco. In 2025 it launched an Off-Peak Charging Credit for off-peak home charging. Duke’s 2025 materials listed two weekday off-peak windows. One ran 10 a.m. to 6 p.m. The other ran 11 p.m. to 5 a.m. Weekends and holidays were listed as off-peak all day. Confirm the current windows on your Duke bill. Don’t set the car once and forget last year’s hours.
That split window is easy to mis-set. A car waiting for 10 a.m. sits dark all night. You leave for the Veterans Expressway at 7 a.m. with yesterday’s miles. A car waiting for 11 p.m. can miss you too. Plug in at 10:30 after a late run. Pull out at 5:15 and the session barely started.
Tampa Electric, TECO, serves the City of Tampa and most of Hillsborough County. It also covers parts of Pinellas and southern Pasco. TECO offers Residential Service Variable Pricing, RSVP-1, as a time-of-use plan. Current RSVP-1 hours weren’t confirmed on the primary pages reviewed here. Read them on tampaelectric.com or in the TECO app. Don’t copy a Pinellas neighbor’s Duke hours onto a TECO meter.
North and central Pasco is often Withlacoochee River Electric Cooperative, not Duke or TECO. If your bill says WREC, use WREC’s own charging guidance. Don’t call TECO or Duke about a credit they don’t run. What shapes Tesla home charging cost in Tampa Bay shows which utility you are on.
Every major EV lets you set a departure time or an off-peak window. Open the app or the center screen. Look for scheduled charging, charge on departure, or off-peak charging. If you need a full pack by breakfast, turn the schedule off tonight. See whether the session actually runs.
Condo outlets and older Pinellas garages
Shared 120-volt outlets are the other overnight pattern, especially in Pinellas condos.
Lealman has the oldest housing in this metro’s scope, with 56.6 percent built before 1980. St. Petersburg is next at 51.5 percent. Those garages weren’t designed for a 240-volt EV circuit. A borrowed outlet on a GFCI looks connected all night. Humidity or a storm flicker can kill power after midnight. The handle is still locked in the port at dawn.
Florida Statute 718.113(8) covers condo EV stations. A unit owner may install one in a limited common element. An exclusively designated parking space also qualifies. The board can’t deny a properly submitted request. The owner pays for the station, insurance, and separately metered power. Many Pinellas and beach drivers still overnight on Level 1 for now. Read What a Level 1 EV charger is, and why it isn’t enough here for overnight Level 1 limits.
Newer master-planned tracts sit at the other extreme. In Westchase, only 1.0 percent of housing was built before 1980. Fish Hawk sits at 0.8 percent, and Lakewood Ranch at 0.7 percent. 240-volt home charging is near-universal there. If that Level 2 sat connected and gained nothing, the wall is probably fine. Go back to the schedule and the 12-volt.
Heat, the 12-volt, and a car that never woke
Tampa Bay runs a long air-conditioning season from spring into late fall. Recurrent Auto’s research finds about 5 percent range loss at 90°F. Loss rises to 20 to 30 percent above 95°F. It’s roughly 17 to 18 percent near 100°F. Results vary by model. That’s road range, not proof your charger failed. Cabin cooling on a hot driveway spends miles you thought you banked.
The small 12-volt battery has to run the computer that starts a charge. If that battery is weak, a session can begin, then quit while you sleep. Heat here is rough on those batteries. You may also see dead screens or stubborn door handles. The car may not wake at all. What happens when an EV 12-volt battery dies in Tampa Bay covers those signs.
Cars plugged in early for a late window can drop into a low-power sleep. Some don’t wake cleanly when the clock hits off-peak. Open and close a door. Unlock with the fob. Start climate from the app. If charging begins a few minutes later, the car was asleep.
Quick reference: cause and first check
| What you see | Likely cause | What to check first |
|---|---|---|
| Same percentage, cable seated | Schedule missed the night | App: scheduled charging, then your utility hours |
| Unplug and replug, then it starts | Sleep before the window | Open a door or start climate in the app |
| Charging stopped partway | Limit hit, or power dropped | Charge limit, then breaker or GFCI |
| Charger light on, car quiet | Loose handle or failed start | Reseat until the port clicks |
| Breaker or GFCI tripped | Circuit fault, not the car | Reset once. Stop if it trips again. See the breaker guide |
When it isn’t a settings problem
Reseat the plug fully. A short wall cable under tension can work itself loose overnight. Listen for the port to click.
If the circuit is dead, reset the breaker or GFCI one time. Don’t keep flipping it. Repeated trips mean a real electrical fault. That’s a licensed electrician’s job, not another night of hoping.
Read the status light on the home charging unit. A fault color or blink pattern usually means the wall box needs service. A normal standby light with an error on the car points back to the vehicle. That’s often the schedule or the 12-volt.
If the pack is low and you have to leave
Don’t spend the morning hunting a public stall. You may already need to be on I-4 or I-275. Charge Pro TPA is a referral line. It matches stranded drivers with independent local operators. It doesn’t own trucks or send its own technicians. Operators bring a 240-volt Level 2 source to the car. They typically add 10 to 20 miles in 15 to 30 minutes of charging. That’s charging time, never an arrival time. The operator quotes you before work starts and bills you directly.
Ask for mobile EV charging when the home session never ran. Miles look tight in this heat. Read EV running low on battery: what to do in Tampa Bay heat.
Call (813) 536-4545 to get matched with a local operator. Confirm the quote before anything starts.
Frequently asked questions
Why did my EV say it was charging when the percentage never rose?
The scheduled window often hadn’t opened yet. A charge limit already met can look the same. Check both in the app before you assume the hardware failed.
Can leaving an EV plugged in without charging hurt the battery?
No. An idle cord doesn’t stress the high-voltage pack. The car is simply not drawing power yet.
Should I keep resetting the breaker if the charger has no power?
Reset it once. If it trips again, stop and call an electrician. A repeating trip is protecting the circuit.
