BYD Dolphin Charging Time Chart: Every Speed, Every Scenario
On a 7 kW home wallbox, the BYD Dolphin charges from empty to full in about 6.4 hours (Standard Range) or 8.6 hours (Extended Range). On DC fast charging, 10 to 80 percent takes roughly 30 to 45 minutes. The portable Mode 2 cable is overnight-slow at around 19 to 26 hours for a full charge, making it a top-up tool. Full charts for every speed and scenario are below, with all working shown.
Dolphin Charging Times at a Glance
| Measurement | Standard Range | Extended Range |
|---|---|---|
| 7 kW wallbox, 0 to 100% | About 6.4 hours | About 8.6 hours |
| DC fast, 10 to 80% | Roughly 31 to 45 minutes | Roughly 29 to 45 minutes |
| Portable cable, 0 to 100% | About 19.5 hours | About 26.3 hours |
| Battery (market) | About 44.9 kWh | About 60.5 kWh |
What Is Manual-Verified and What Is Market-Sourced
Honesty about sources makes a chart trustworthy, so here is the split up front. The owner's manual documents the three charging methods, the portable Mode 2 cable, AC charging piles, and DC charging piles, along with the charging procedures, the electronic port lock, and reservation charging. The manual quotes battery capacity in amp-hours, 135 and 150 Ah.
The kilowatt-hour pack sizes of about 44.9 and 60.5 kWh, and the charging rates, about 7 kW AC (with 11 kW three-phase supported in some markets) and roughly 60 to 88 kW DC by variant, come from official market specification sheets and are flagged as such. Every time below is calculated from those figures, with the working shown.
Chart 1: AC Charging Times, 0 to 100 Percent
| Measurement | Standard Range (44.9 kWh) | Extended Range (60.5 kWh) |
|---|---|---|
| Portable Mode 2 cable (about 2.3 kW) | About 19.5 hours | About 26.3 hours |
| 7 kW home wallbox | About 6.4 hours | About 8.6 hours |
| 11 kW three-phase (where supported) | About 4.1 hours | About 5.5 hours |
The method is simple division: pack size in kWh divided by charging rate in kW. A 7 kW wallbox turns any overnight window into a full battery, which is why it is the setup most owners land on.
Chart 2: DC Fast Charging, 10 to 80 Percent
| Measurement | Standard Range (about 60 kW peak) | Extended Range (about 88 kW peak) |
|---|---|---|
| Energy added (70% of pack) | About 31.4 kWh | About 42.3 kWh |
| Calculated minimum at peak rate | About 31 minutes | About 29 minutes |
| Real-world expectation | Roughly 35 to 45 minutes | Roughly 35 to 45 minutes |
The calculated rows assume the peak rate held flat, which no EV does: charging tapers as the battery fills. So treat the calculated figure as the theoretical floor and the real-world row as your planning number, a comfortable coffee-length stop.
Chart 3: Real-World Scenarios
| Measurement | Time |
|---|---|
| Daily commute top-up (about 15 kWh) on a 7 kW wallbox | About 2.1 hours |
| Daily top-up on the portable cable | About 6.5 hours, an easy overnight |
| 40 to 100% overnight, 7 kW wallbox | About 3.8 hours (Standard) / 5.2 hours (Extended) |
| Road-trip splash, DC 10 to 80% | Roughly 35 to 45 minutes |
The everyday truth these scenarios reveal: most days you are not charging from empty. A typical commute's energy goes back in within a couple of hours on a wallbox, or overnight even on the humble portable cable.
What Affects Your Actual Times
- Cold weather: The manual notes the temperature control system conditions the battery in low temperatures, which can extend charging time and slightly increase energy used
- The taper: DC speed falls as the battery fills, which is why 80 to 100 percent on DC is slow and best done on AC at home
- Charger sharing and limits: A pile's output capacity can limit the rate, per the manual, so a busy or lower-rated charger delivers less than the car's peak
- Climate running during charging: The manual notes using the A/C while charging modestly extends time and consumption
Manual Procedures Worth Knowing
- The port locks electronically: Unlock the car before unplugging, as the connector locks during charging
- On DC, stop at the charger first: End the session at the pile before disconnecting
- It stops itself when full: Charging ends automatically at completion
- Reservation charging: Toggle it on, set a start time, and the car charges in your cheap off-peak window automatically
