With its sleek design, impressive range, and eco-friendly credentials, it’s no wonder that many buyers are considering a used model. However, one of the most significant concerns for potential buyers is battery degradation. So, what can you expect when it comes to the battery health of a used Hyundai Ioniq Electric? Let’s dive in. ## Key facts - The Hyundai Ioniq Electric has an MOT pass rate of 87.9%, based on 3,877 DVSA MOT tests. - The national average pass rate for all models is 79.1%. - Most common MOT problems include tyres (47.9%), brakes (21.9%), and lights (8.7%). - The fail rate for Ioniq Electric models under 40,000 miles is 9.8%. - The worst manufacture years for MOT fail rates are 2019 (13.6%) and 2018 (12.8%). - For more detailed statistics, check out the [Make Model MOT pass rate statistics](https://carbuyeriq.com/mot-pass-rates/hyundai/ioniq). ## Understanding Battery Degradation Battery degradation is a natural process that occurs in all lithium-ion batteries over time. In the case of the Hyundai Ioniq Electric, the battery pack is designed to last for many years, but factors such as usage patterns, charging habits, and environmental conditions can all impact its longevity. ### What Causes Battery Degradation? Battery degradation occurs due to a variety of factors: 1. **Charge Cycles**: Each time you charge and discharge the battery, it goes through a cycle. The more cycles a battery goes through, the more its capacity diminishes. For the Ioniq Electric, the battery is rated for around 1,000 charge cycles before significant degradation occurs. 2. **Temperature**: Extreme temperatures can affect battery health. High temperatures can accelerate degradation, while very low temperatures can temporarily reduce capacity. Ideally, the Ioniq Electric should be charged and stored in moderate temperatures. 3. **Depth of Discharge**: Regularly discharging the battery to very low levels can also contribute to faster degradation. Keeping the battery between 20% and 80% charge is generally recommended for optimal health. ### What to Expect from a Used Ioniq Electric When considering a used Hyundai Ioniq Electric, it’s essential to understand what level of battery degradation you might encounter. Generally, you can expect the following: - **Battery Health**: Most used Ioniq Electric models will still retain a significant portion of their battery capacity, often around 80% or more after several years of use. However, this can vary based on the factors mentioned earlier. - **Real-World Range**: The Ioniq Electric has a manufacturer-claimed range of around 180 miles on a full charge. However, real-world conditions can affect this figure. Expect a range of approximately 130 to 150 miles in everyday driving, especially in colder weather or with heavy use of climate control. - **Battery Warranty**: Hyundai offers an impressive warranty on the Ioniq Electric’s battery, typically covering 8 years or 100,000 miles, whichever comes first. This warranty can provide peace of mind when purchasing a used model. ## Checking Battery Health Before you commit to buying a used Ioniq Electric, it’s crucial to check the battery health. Here are some steps you can take: ### 1. Use a Battery Health Check Tool Many EVs, including the Ioniq Electric, come equipped with onboard diagnostics that can provide information about battery health. You can often access this data via the car’s infotainment system or through a dedicated app. Look for metrics like state of health (SoH) and state of charge (SoC). ### 2. Get a Professional Inspection If you’re unsure about interpreting the data, consider getting a professional inspection. A qualified technician can perform a thorough battery health check and provide insights into the battery’s condition. ### 3. Review the MOT History Checking the MOT history of the vehicle can also give you clues about its overall condition. The Hyundai Ioniq Electric has an MOT pass rate of 87.9%, which is above the national average of 79.1%. You can check the MOT history for any recurring issues that might indicate battery-related problems, such as electrical faults. For a detailed history, visit the [GOV.UK MOT history checker](https://www.gov.uk/check-mot-history). ### 4. Look for Signs of Overcharging If the previous owner frequently charged the vehicle to 100% or left it plugged in for extended periods, this could lead to accelerated battery degradation. Ask about their charging habits to gauge how well they maintained the battery. ## Real-World Range vs Manufacturer Claims As mentioned earlier, the Hyundai Ioniq Electric has a manufacturer-claimed range of around 180 miles. However, real-world conditions often lead to different results. Here’s what you can expect: ### Factors Affecting Real-World Range 1. **Driving Style**: Aggressive acceleration and high speeds can significantly reduce range. If you’re a lead-footed driver, expect to see lower numbers. 2. **Climate Control**: Using the air conditioning or heating can also impact range. In colder months, you might find your range drops by as much as 20% due to heating needs. 3. **Terrain**: Hilly or mountainous areas can drain the battery faster than flat terrain. If you live in a region with lots of elevation changes, be prepared for a shorter range. 4. **Load**: Carrying extra weight, whether it’s passengers or cargo, can also affect how far you can go on a single charge. ### Real-World Range Estimates In real-world conditions, you can typically expect the Ioniq Electric to deliver a range of around 130 to 150 miles. This is a reasonable figure for daily commuting and short trips, but it’s essential to plan for longer journeys, especially if you’re relying on public charging stations. ## Charging Costs and Infrastructure Charging costs are a significant consideration for anyone thinking about switching to an electric vehicle. Here’s what you need to know about charging your used Hyundai Ioniq Electric: ### Home Charging If you have access to a home charging point, you can charge your Ioniq Electric overnight. The vehicle comes with a standard 7.2 kW onboard charger, which means it can fully charge from empty in about 6 to 8 hours. This is ideal for overnight charging when electricity rates are typically lower. ### Public Charging For those who rely on public charging, the Ioniq Electric is compatible with both AC and DC charging stations. Fast chargers can replenish the battery to about 80% in around 54 minutes, making it convenient for longer trips. However, public charging costs can vary significantly, so it’s wise to check local rates. On average, expect to pay around £0.20 to £0.30 per kWh at public charging stations. ### Cost Savings When comparing the running costs of the Ioniq Electric to petrol or diesel vehicles, the savings can be substantial. Charging a fully depleted Ioniq Electric might cost around £5 to £8, depending on electricity rates. In contrast, filling up a petrol car could easily set you back £60 or more, depending on fuel prices.

Being aware of common problems can help you make an informed decision: ### 1. Software Glitches Some owners have reported software glitches that can affect the infotainment system and navigation. While these can often be resolved with updates, it’s worth checking if the vehicle has been kept up to date. ### 2. Battery Management System Issues In rare cases, the battery management system may malfunction, leading to inaccurate battery readings or reduced performance. If you notice any unusual behaviour, it’s essential to have it checked out. ### 3. Charging Port Problems Some users have experienced issues with the charging port, including difficulty connecting to chargers or intermittent charging. Inspect the charging port for any signs of wear or damage before purchasing. ### 4. Tyre Wear As noted in the MOT statistics, tyres are the most common area for defects in the Ioniq Electric, accounting for 47.9% of issues. Regularly check the condition of the tyres and ensure they are properly inflated to avoid premature wear.
