Charging times for the BYD Sealion 7 RWD Comfort by charger type. 10 to 80% is the standard comparison because rapid charging slows sharply above 80%.
BYD Sealion 7 RWD Comfort charging slower than it should?
Charging faults are usually the car, the cable or the charger. Get a local EV specialist to check it.
Charging the BYD Sealion 7 RWD Comfort at home
A 7kW home wallbox is the workhorse. From 10% to 80% takes about 9h 10m, and a full charge from empty about 13h 6m, which fits comfortably overnight. On a cheap overnight tariff window, that is also the cheapest way to run the car by a distance.
A standard 3-pin socket manages around 2.3kW. A full charge that way takes roughly 39h 51m, so treat it as a backup rather than a routine. A spare granny cable for the boot, or a Type 2 cable for untethered public posts, is in our EV charging cables and chargers collection, built to order in the UK by Wottz.
The car's on-board AC charger takes up to 11kW, so on a 22kW public AC post it still charges at 11kW: about 5h 50m for 10 to 80%.
To get the full 11kW on a three phase public post, use a 22kW Type 2 cable. A 7.4kW cable works but caps the car at 7.4kW. At home on single phase, a 7.4kW cable already gives full speed. More on which EV charging cable you need.
Rapid charging on trips
On a 50kW rapid charger, 10 to 80% takes about 1h 38m. On a rapid charger that can match the car's 150kW peak, that drops to about 39 minutes.
These are real-world estimates, not brochure figures: cars only hold their peak rate for part of the session, and the rate tapers steeply above 80% to protect the battery. That is why topping up to 80% and driving on beats waiting for 100% on every trip.
Cold batteries charge slower. In winter, expect the first rapid stop of the day to run behind these times until the pack warms up.
Powering appliances from the BYD Sealion 7 RWD Comfort (V2L)
The BYD Sealion 7 RWD Comfort supports vehicle to load, or V2L. With a V2L adapter in the charge port, the car's battery becomes a 230V mains supply for a laptop, power tools, a camping hob, or lights and a fridge in a power cut. The handbook gives the most it will supply, so check that before plugging in anything that heats up.
Our V2L cable for BYD cars is built to order in the UK by Wottz. You choose the socket (UK single or double, waterproof, Schuko or blue 16A) and a lead from 0.5m to 15m, so the socket can reach a tent, a garden or a workbench while the car stays on the drive.
Most cars let you set a battery level where V2L switches off, so you always keep enough charge to drive.
More on what it can run, and which other cars have it, in our V2L guide.
