Charging your BYD Seal at home

A few quick questions, then see how fast you could charge at home.

Question 3 of 3

BYD Seal

Is your switchboard ready for fast charging?

Your switchboard is the box of switches that controls your home’s power — some people call it the fuse box. Fast charging needs one that can handle more. Most people don’t know, and that’s completely fine.

Before you choose

Is your switchboard ready for fast charging?

Your switchboard — some people call it the fuse box — decides what kind of charger your home can take. Most people have no idea whether theirs is ready. That’s what the discovery call is for.

Electrician upgrading a switchboard

Signs it may need some work first

  • Old fuses you replace with fuse wire, instead of switches
  • No spare space on the board
  • No safety switches, or only one for the whole house
  • The power cuts out when the oven, air-con and dryer run together
  • The board is as old as the house, and the house is from the 1970s or 80s

If yours needs work, we’ll explain exactly what and why, in plain English, before anything happens. More on switchboard upgrades.

The process

What happens after you book a call

  1. A discovery call

    About 10 minutes on the phone. We ask about your car, your home and how much you drive.

  2. We check your switchboard

    Usually from a couple of photos you send us — no visit needed. You find out what your home can take.

  3. You choose, we install

    Slow or fast, you decide with all the facts. Most installs take half a day.

  4. Signed off

    We test everything, show you how it works, and give you the official safety certificate NSW requires.

Charging the BYD Seal at home

How long does the BYD Seal take to charge at home?
From nearly empty to full: about 13 hours with a fast charger, or about 25 hours with a slow one. On the cable that came with the car, plugged into a normal power point, it's closer to 39½ hours. Most days you're only topping up — a fast charger puts back a typical day's driving in about 55 min, a slow one in about 1 hr 50 min.
What's the best home charger for the BYD Seal?
A fast charger charges the BYD Seal about 2 times faster than a slow one — about 40 km of driving every hour instead of 20. It needs a switchboard that's ready for it. A slow charger works in any home and still tops up most days overnight. A quick discovery call tells you which fits your home.
Do I need a home charger if I buy an electric car?
You can get by with the cable that comes with the car and public chargers, but almost every owner ends up wanting one. A wall charger fills the car faster than a normal power point — a fast one many times faster — charges overnight when power is cheapest, and is much safer for charging that runs for hours.
What’s the difference between a slow and a fast charger?
Speed, and what your home needs. A slow charger works on the power every home already has, and tops up a day’s driving in a couple of hours. A fast charger is usually three times quicker or more, and can fill most cars in a few hours — but it needs a switchboard and power supply that are ready for it.
How do I know if my switchboard is ready for fast charging?
Most people don’t, and that’s fine. Fast charging needs a stronger power supply than most homes have (electricians call it three-phase power), and a switchboard with room for it. On a discovery call we can usually tell from a couple of photos — no visit needed.
What is a discovery call?
A free phone call with a licensed electrician — not a call centre. We ask a few simple questions about your car, your home and how you drive, and tell you what your options are. It takes about 10 minutes.
How much does it cost to run an electric car?
Much less than petrol. Charging overnight on an off-peak rate usually works out to a few dollars per 100 km, and charging from your own solar panels is close to free.
Will the charger work with my next car?
Yes. Every electric car sold in Australia, Teslas included, uses the same plug for home charging. A good charger outlasts the car it was bought for.
Can I charge from my solar panels?
Yes. Some chargers can send your spare solar power into the car instead of back to the grid, which is worth far more to you. We’ll tell you if it suits your setup.
How long does installation take?
Most installs are done in half a day. A long way between the switchboard and where you park, a detached garage, or a switchboard upgrade can make it a full day. You’ll know which before we start.
I live in a strata building. Can I still get one?
Usually, yes — NSW strata law now makes it much harder for an owners corporation to refuse a reasonable EV charger request. We can help with what the committee needs to see.
Can you install a charger I’ve already bought?
Yes, as long as it’s approved for Australia and suits your home. If you haven’t bought one yet, we’ll tell you what actually matters for your car.
