How can I check the health of my EV battery in New Zealand?

When buying or owning an electric vehicle, one of the most important questions is: how healthy is the battery? Since the battery is the most valuable part of an EV, knowing its condition is vital for peace of mind and resale value. At GVI, we use the Aviloo Battery Scanner — a world-leading independent EV battery testing system — to give you a clear, certified picture of your EV’s battery health.

Q: Why is EV battery testing important?

A: Over time, all EV batteries lose capacity due to normal wear. This affects range and performance. Unlike petrol cars, where you can check kilometres and service history, the battery’s health isn’t visible without specialised testing. That’s where Aviloo comes in — providing an accurate report on how your EV’s battery is performing.

Q: What is the Aviloo Battery Scanner?

A: The Aviloo Battery Scanner is an independent testing tool that connects directly to your EV. It measures the state of health (SOH) of your battery by analysing performance across real-world driving. The result is a certified battery health report, trusted worldwide by dealers, buyers, and insurers.

Q: How does the test work at GVI?

A:

1. We plug in the Aviloo device to your EV.

2. Aviloo analyses thousands of data points.

3. You receive a clear Battery Certificate showing the detailed dyagnostic of your EV Battery including SOH

Q: Which EVs can be tested with Aviloo?

A: The Aviloo system works with a wide range of models, including Nissan Leaf, Tesla Model 3, Hyundai Kona, Mitsubishi Outlander PHEV, Peugeot e-208/e-2008, Polestar , Mercedes EQA & EQC and many more. If you’re not sure about your EV, ask our team — we’ll confirm compatibility.

Q: How does this help when buying or selling an EV?

A:

• Buyers: Get peace of mind that the EV you’re purchasing has a healthy battery.

• Sellers: Add value to your listing with a certified battery health report.

• Owners: Track your EV’s battery over time to plan servicing or resale.
