Denza Z9GT
Charging cable
Charges about 50% faster on 22 kW public posts than a 7.4 kW cable.
Why this fits your Z9GT+−
The Denza Z9GT has a Type 2 inlet and a three-phase 11kW onboard charger. The 22kW cable carries its full 11kW on three-phase chargers. A 7.4kW cable would cap it. On a single-phase home wallbox both cables charge at the same 7.4kW.

Charging
the Denza Z9GT.
The Denza Z9GT is a large premium electric estate from BYD's Denza brand, arriving in the UK from 2026 with a 100.1kWh battery and a substantial 270kW DC rapid charging capability on provisional European specification. Denza positions the Z9GT as a performance-focused load carrier, combining genuine estate practicality with a high-voltage architecture that puts it alongside the most capable EV chargers on the market. The AC inlet is Type 2, the standard for all UK public chargers and home wallboxes.
When you park up at a wallbox or an AC public point, the cable you need is a Type 2 to Type 2 lead. The Z9GT's onboard charger accepts up to 11kW across three phases. DC rapid charging, at up to around 270kW, uses the tethered cable at the rapid charger itself, so you do not buy a cable for that.
The Z9GT's 100kWh battery means even a 7.4kW home wallbox provides a comfortable overnight top-up from a typical daily deficit. Rapid (DC) times are for a 10 to 80% charge, the way manufacturers quote them. Real-world charging varies with temperature, battery state and the charger itself.
7.4 kW or 22 kW?
Which cable does
the Z9GT need?
The Z9GT's onboard AC charger is rated at 11kW on three phases, which means the charger hardware can handle more than a standard UK home wallbox supplies. Most UK homes have a single-phase supply, and that caps AC charging at 7.4kW regardless of cable rating. For the majority of Z9GT owners, a 7.4kW Type 2 cable delivers exactly what their home setup can provide, and the 100kWh battery will still replenish overnight comfortably.
A 22kW cable only earns its cost if you have a three-phase supply at home, which is rare in the UK, or if you regularly pull up at 22kW public AC points. When you do connect to a three-phase 22kW point, the Z9GT will draw its full 11kW. On any single-phase connection the cable rating is irrelevant to speed, so the practical choice for most owners is a quality 7.4kW Type 2 lead rather than paying more for a three-phase cable that delivers no real benefit at home.
A 5m cable suits most driveways; choose 7m or 10m if your wallbox is set back or the charging port ends up on the far side of the car from the socket.
What does it cost to charge?
Filling the Z9GT's 100.1kWh battery from empty costs roughly £7 to £8 on an off-peak EV tariff of around 7.5p per kWh, or around £27 on a standard rate of around 27p per kWh. Given the battery size, setting up a dedicated overnight EV tariff makes a meaningful difference to running costs. Public rapid charging is considerably dearer, often 45p to 80p per kWh, so it works best as a top-up on long journeys. Check current tariff rates, as they move regularly.

Denza Z9GT FAQs
Good
questions.
Still not sure? Our team will confirm the right cable for your vehicle.
Contact usWhat length charging cable should I get?+−
5m suits most home and public charge points. Choose 7.5m or 10m if the charge point is far from your car's charging port or you park on the far side of a bay.
What charging cable does the Denza Z9GT need?+−
A Type 2 to Type 2 cable for home wallboxes and public AC points. A 7.4kW cable suits the vast majority of UK owners on a single-phase supply. A three-phase 22kW cable is worth considering only if you have a three-phase supply or regularly use 22kW public AC chargers, where the Z9GT will draw up to 11kW.
Can the Denza Z9GT charge at 22kW?+−
No. The Z9GT's onboard AC charger is rated at 11kW on three phases, so it cannot accept more than 11kW on AC. A 22kW cable will not make it charge faster. On a standard UK single-phase home supply it charges at 7.4kW, whatever cable is used.
How long does the Denza Z9GT take to charge at home?+−
On a 7.4kW single-phase home wallbox, the 100.1kWh battery takes roughly 13 to 14 hours from empty to full, though in practice you rarely start from empty. Charging overnight from a typical daily deficit of 30 to 50% is well within reach on any standard 7.4kW wallbox.
What is the DC rapid charging speed of the Denza Z9GT?+−
The Z9GT supports DC rapid charging at up to around 270kW on provisional European specification. DC charging uses the tethered cable at the rapid charger, not a cable you bring. This makes long motorway runs fast, though the exact peak speed may vary once UK-specific figures are confirmed.
