The Kia EV6 and EV9 are among the most capable electric cars you can buy in the UK — 800V architecture, blistering DC charging speeds, and genuine vehicle-to-load (V2L) capability. But for everyday AC charging at home or a public post, you need a simple Type 2 cable, 32A, three-phase if you can. Here’s what the 11kW onboard charger means in practice, how V2L actually works, and how to choose the right cable for your Kia.
Which cable does your Kia EV need?
Every current Kia EV sold in the UK — the EV6, EV9, and EV3 — uses a Type 2 (IEC 62196-2) inlet for AC charging. That means the cable you need is a Mode 3 Type 2-to-Type 2 lead, rated at 32A. The connector on both ends is the same seven-pin Type 2 plug: one end goes into your car, the other into a public AC post or home wallbox.
For the EV6 and EV9 specifically, you want a three-phase cable. According to Kia’s published EV6 and EV9 charging specifications, both cars carry an 11kW onboard AC charger that operates on three-phase supply. A three-phase 32A cable lets you draw the full 11kW wherever three-phase power is available; a single-phase cable will cap you at 7.4kW even if the charger is capable of more.
Neither the EV6 nor the EV9 ships with a Mode 2 granny cable (the brick-on-a-lead style you might plug into a domestic socket). If you want a home trickle-charge option as a backup, that’s a separate purchase — but for most owners, a wallbox and a proper Mode 3 cable is the right setup.

11kW onboard charger: what it means at home and public posts
The 11kW figure is the ceiling, not a guarantee. To reach it you need three things to align: a three-phase supply at the charge point, a three-phase capable cable, and a charger that can deliver 11kW per phase simultaneously.
At home, most UK domestic wallboxes are single-phase (up to 7.4kW). That’s perfectly fine for overnight charging — an EV6 or EV9 will top up comfortably overnight on 7.4kW. Where the 11kW rating earns its keep is at public three-phase AC posts (common in supermarket car parks, workplace chargers, and destination charging hubs). Plug in with a three-phase cable and you’ll see the full 11kW session rate.
One correction worth making: you may see some third-party listings or forum posts claim the EV6 can charge at “up to 22kW.” That’s wrong. Neither the EV6 nor the EV9 has a 22kW onboard charger. The maximum is 11kW three-phase, as confirmed by Kia’s published EV6 and EV9 charging specifications. A 22kW cable won’t harm your car — it will just charge at 11kW regardless — but there’s no reason to pay a premium for a 22kW-rated cable if the car can’t use the extra capacity.

800V architecture: why it matters for DC but not AC
The EV6 and EV9 run on Hyundai Motor Group’s E-GMP platform, which uses an 800V battery architecture. Most EVs on the market use 400V systems. The higher voltage allows significantly faster DC charging because power (watts) equals voltage multiplied by current — at 800V you can push the same power with less current, which means less heat and the ability to charge at higher wattages.
In practice, this means the EV6 and EV9 can use 350kW ultra-rapid DC chargers (such as those operated by Gridserve and Osprey in the UK) and achieve peak real-world rates of around 233kW DC. That translates to genuinely fast charge stops — roughly 10–80% in around 18 minutes under ideal conditions.
For AC charging, the 800V architecture changes nothing. Your Type 2 cable, your wallbox, and your public AC post all operate at standard AC voltages. The onboard charger (11kW) handles the conversion internally. Whether your car is 400V or 800V, the cable and the AC charging experience are identical.
For DC rapid charging, no cable purchase is needed at all. CCS Combo 2 rapid chargers always have a tethered cable at the unit — you simply plug the combined connector into your car’s CCS port. There is no CCS cable to buy.
The EV3, which we cover below, shares the same E-GMP design heritage but uses a 400V architecture — an important distinction if you’re comparing DC charging speeds across the Kia range.
The EV6 and EV9 sit on the same E-GMP platform as Hyundai’s Ioniq 6 and Ioniq 5. If you’re also considering a Hyundai, our Hyundai Ioniq charging cable guide covers the same specification in that context.
V2L capability on the EV6 and EV9 — adapter, ICCU, and what it can power
Both the EV6 and the EV9 support vehicle-to-load (V2L): the ability to export AC power from the car’s battery to household devices. This is one of the more genuinely useful features of the E-GMP platform, and it’s worth understanding exactly how it works — because the implementation varies by trim and the adapter situation trips up a lot of buyers.
How V2L works: the ICCU
Inside every E-GMP vehicle is a component called the ICCU — Integrated Charging Control Unit. During normal AC charging, the ICCU converts incoming AC power to DC to charge the battery. For V2L, it works in reverse: it bi-directionally converts DC battery power to AC output, typically at up to around 3.6kW. This is the hardware that makes V2L possible, and it’s why V2L works without any additional inverter or external device — the conversion happens inside the car.
External V2L: the adapter
The external V2L function uses the car’s Type 2 AC inlet as the output port. A purpose-made V2L adapter plugs into the Type 2 inlet; the other end of the adapter has a standard 3-pin UK socket (or in some cases a CEE socket for European compatibility). You plug your household device into the adapter and draw power from the battery.
Whether the adapter is in the box depends on trim level. Some higher-specification EV9 trims include the V2L adapter as standard equipment. EV6 owners are more likely to find they need to buy it separately — typically around £50–£100 from a Kia dealer or approved accessory supplier. We strongly recommend checking your handover documentation before assuming the adapter is included. If it’s missing, it’s worth raising with the dealer before you leave the forecourt.
Internal V2L sockets
On select trims of both the EV6 and EV9, there are also internal V2L sockets — a standard 3-pin socket fitted inside the boot or cabin. These work without any external adapter: just plug your device directly into the socket in the car. Check the specification sheet for your exact trim level to confirm whether internal sockets are fitted.
For a full guide to V2L adapters, compatibility, and what you can realistically power from your EV’s battery, see our V2L adapter guide.
Kia EV3: same cable, different DC architecture
The Kia EV3 (launched 2024) is the newest addition to the UK Kia EV range, and it shares the same Type 2 inlet and 11kW onboard AC charger as the EV6 and EV9. For AC charging purposes, the same 32A three-phase Type 2 cable applies to the EV3 — no special considerations.
Where the EV3 differs is its DC architecture: 400V, not 800V. This is an important distinction if you’re weighing up which Kia EV to buy, or if you own an EV3 and are curious why its DC rapid charging speeds don’t match the EV6 or EV9. At a 350kW ultra-rapid charger, the EV3 simply cannot match the peak rates of its 800V siblings because of the voltage ceiling of its battery architecture.
For AC home charging and day-to-day use, the distinction doesn’t matter at all. The cable is the same; the wallbox is the same; the experience at a 7kW or 22kW public AC post is identical. The 400V/800V difference only surfaces at DC rapid chargers, and even then the EV3 charges quickly by any reasonable measure — it simply isn’t in the same ultra-rapid tier as the EV6 and EV9.
A note on the Kia EV5: as of mid-2026, the EV5 has not been confirmed for the UK market. If and when it arrives, we’ll update our guidance to reflect its specification.
Getting the length right
Cable length is a practical question that’s easy to underestimate, particularly if you’re buying in advance of your car arriving.
5 metres is the right call for most UK driveways. It’s enough to reach a wallbox mounted beside the garage door from a car parked on a standard single-car drive, with a comfortable loop of slack.
Consider 7 metres if: - Your wallbox is mounted on an external wall some distance from your parking spot - You park on the road and use a public post across the pavement - You drive an EV9 — it’s a genuinely large seven-seat SUV, and the extra length helps ensure you can reach the charge port regardless of which way the car is facing
A note on EV9 specifics: because the EV9 is so long, if you park nose-in on a driveway with the wallbox at the back of the house, a 5m cable may be marginal. The 7m option gives you more flexibility and no meaningful downside beyond the extra cable to coil when you’re done.
Cables longer than 7m are available but add unnecessary bulk and resistance for most users. We haven’t seen meaningful demand for cables beyond 7m in our own data at EV Cable Hub, and we’d only recommend going longer if you have a genuinely unusual installation.
Frequently asked questions
What charging cable does the Kia EV6 need? A Type 2 (IEC 62196-2) Mode 3 cable, 32A three-phase. The EV6’s onboard AC charger is rated at 11kW (3-phase), per Kia’s published specifications. A three-phase cable lets you reach the full 11kW at compatible public posts; on a single-phase home wallbox you’ll get 7.4kW.
What charging cable does the Kia EV9 need? The same as the EV6: a Type 2 cable, 32A three-phase. The EV9 also has an 11kW onboard 3-phase AC charger. Given the EV9 is a larger vehicle, pay attention to cable length — a 7m cable gives more reach on a big driveway with an oversized SUV.
Does the Kia EV6 or EV9 come with a V2L adapter? V2L adapter inclusion depends on trim level. Some higher-specification EV9 trims include the V2L adapter in the box; EV6 owners often need to buy it separately. Check your handover paperwork. The external V2L adapter plugs into the Type 2 inlet and provides a standard 3-pin socket output for household devices.
How does V2L work on the Kia EV6 and EV9? V2L (vehicle-to-load) uses the ICCU — the Integrated Charging Control Unit in the E-GMP platform — to bi-directionally convert DC battery power to AC output. The external V2L adapter plugs into the car’s Type 2 AC inlet and outputs up to around 3.6kW AC to standard household sockets. Internal V2L sockets (in the boot/cabin) are available on select trims without any adapter.
Is the Kia EV6 an 800V car? Yes. The EV6 uses Hyundai Motor Group’s E-GMP platform with an 800V battery architecture. This means it can charge at ultra-rapid 350kW DC chargers (with peak real-world rates around 233kW). For AC home charging, the architecture doesn’t change anything — it’s still 11kW via a standard Type 2 cable.
Does the Kia EV3 have the same charging spec as the EV6? The EV3 also uses a Type 2 inlet and 11kW onboard AC charger, so the same cable applies. However, the EV3 uses a 400V battery architecture rather than 800V — this means slower peak DC charging rates than the EV6 or EV9, though it doesn’t affect AC charging.
Do I need a cable for DC rapid charging a Kia EV? No. CCS rapid chargers always have tethered cables at the charger unit. Just plug the CCS connector (the combined Type 2 + two DC pins) into your car’s CCS port. No cable purchase required for DC rapid charging.
