Kia EV6 Battery Health Check

Kia EV6 — Battery Overview

The Kia EV6 shares Hyundai's E-GMP platform with the Ioniq 5, delivering the same 800V architecture in a sportier crossover body. It is available with two battery options: the Standard Range (58 kWh) and the Long Range (77.4 kWh), in rear-wheel-drive and all-wheel-drive configurations. WLTP range reaches up to 328 miles on the Long Range RWD variant. The performance-oriented GT model produces 585 PS and reaches 0–62 mph in 3.5 seconds.

The EV6 uses a liquid-cooled thermal management system and NMC battery chemistry — the same proven setup as the Ioniq 5.

Common Battery Concerns

The EV6 is a strong performer, but dealers should be aware of:

  • GT model energy consumption — The high-performance GT variant consumes significantly more energy under spirited driving. Buyers upgrading to or from a GT may have different range expectations than the WLTP figure suggests.
  • Ultra-fast charging history — Like the Ioniq 5, the EV6's 800V architecture supports 350 kW charging (10–80% in approximately 18 minutes). Vehicles used primarily on rapid chargers may show slightly higher wear.
  • Limited SoH transparency — Kia, like Hyundai, does not expose State of Health data to owners through standard dashboards or apps. Buyers have no easy way to verify battery condition without an independent test.
  • Towing capability — The EV6 is rated for braked towing up to 1,600 kg. Vehicles used regularly for towing will have experienced higher energy throughput.

How the AVILOO FLASH Test Works on the EV6

The test takes around three minutes:

  1. Plug the AVILOO Box into the EV6's OBD-2 port beneath the dashboard
  2. Wait while the Box reads battery data and transmits it to AVILOO's servers
  3. Receive a TÜV-certified certificate immediately — no driving required

Works on all variants including the GT.

What the Certificate Shows

The AVILOO certificate for a Kia EV6 includes:

  • State of Health (SoH) — an independent reading, crucial given Kia's limited native SoH visibility
  • Cell-level heatmap — individual cell condition with clear visual indicators
  • Certified energy (SoCE) — actual remaining capacity in kWh
  • Range estimates — WLTP-based, real-world, and peer-comparison figures
  • Benchmarking — comparison against other EV6s of similar specification and age
  • QR code for digital verification

The EV6 commands strong used values. A battery health certificate justifies premium pricing and gives buyers the confidence to pay it.

Protect Your Business

Under the Consumer Rights Act 2015, dealers bear the burden of proof for faults within six months. On a vehicle with an average transaction price above £30,000, the cost of a dispute — averaging £6,193 — is significant. A £35 battery test is straightforward risk management.
