As the number of electric vehicles entering the remarketing sector continues to grow, the main question being asked by buyers is ‘what condition is the battery in?’
At Copart, we’ve seen first-hand how attitudes towards electric vehicles have evolved over the last few years.
From the early stages of EV adoption to today’s rapidly growing marketplace, we know that battery condition has become one of the most important considerations for buyers looking to make informed purchasing decisions.
Understanding battery health can help buyers assess value more accurately, identify genuine opportunities, and bid with greater confidence.
Understanding Battery Health
Battery health is commonly measured using a State of Health (SoH) percentage, which compares a battery’s current capacity against the capacity it had when new.
For example, a battery with a 90% SoH can still store around 90% of the energy it was originally designed to hold.
Battery degradation is a natural part of an EV’s lifecycle. Factors such as mileage, age, charging habits, and environmental conditions can all influence how quickly a battery loses capacity over time.
Degradation does not necessarily indicate a fault and many EVs remain highly effective after some capacity reduction has occurred, but battery health matters and remains an important consideration for buyers.
Why Battery Health Matters
Understanding battery condition can help buyers:
- Assess a vehicle’s likely market value
- Estimate potential driving range
- Evaluate repair viability
- Identify opportunities where the battery remains healthy despite other damage
- Make more informed bidding decisions
As with any vehicle purchase, having access to the right information helps to reduce uncertainty and improve confidence.
Transparency is Driving Buyer Confidence
As the EV market continues to grow, buyers are increasingly seeking greater transparency around battery condition.
We’ve recognised this demand and have continued to invest in technologies and processes that provide greater visibility into the condition of electric vehicles entering the Copart marketplace.
Battery health reporting offers valuable insight into a vehicle’s most important component and helps buyers make better-informed decisions.
As battery diagnostics become more sophisticated, the availability of condition data is helping to remove some of the uncertainty traditionally associated with used and salvage EVs.
Looking Beyond Visible Damage
One of the most common misconceptions surrounding salvage EVs is that any collision automatically means battery damage.
From our experience handling and remarketing electric vehicles, we know this is often not the case. Many vehicles have sustained bodywork or cosmetic damage while the battery system remains unaffected.
In some cases, repair costs and labour requirements can result in a vehicle being declared a total loss despite the key EV components remaining in good condition.
For knowledgeable buyers, understanding the difference between visible damage and battery condition can reveal opportunities that might otherwise be overlooked.
What Information Should Buyers Look For?
Where available, buyers should review all vehicle information provided within the auction listing.
- Vehicle Age and Mileage
Age and mileage provide useful context when assessing likely battery condition and overall vehicle wear.
Many modern EV batteries continue to retain a significant proportion of their original capacity well beyond 100,000 miles.
- Service and Maintenance History
A vehicle with a documented maintenance record may offer additional reassurance regarding ownership and care.
- Battery Condition Reports
Where battery health information is available, buyers should review any diagnostics or condition reports provided.
Earlier this year, at Copart, we introduced a new EV Battery Health Report in partnership with Aviloo — a trusted independent specialist in EV battery diagnostics.
Where available, this report will be provided for electric and plug-in hybrid vehicles in our online auctions, giving our buyers even greater visibility and confidence when bidding.
They will be able to access a detailed overview of the battery condition, including an overall battery health score (State of Health (SoH) score), insights into voltage performance, and identification of any potential faults.
Together, these insights can help buyers build a clearer picture of battery condition and performance.
- Location of Damage
The location and nature of any visible damage also need to be carefully considered.
Close attention should be given to vehicles with significant underbody damage or impact near to high-voltage components. On the other hand, damage confined to body panels or external vehicle structures may have little or no impact on battery condition.
Understanding State of Health Scores
While battery performance varies between manufacturers and vehicle types, this consumer valuation data published by EV Compared may help buyers understand battery health results.
- Above 90% SoH | Very Good – in near-perfect condition with minimal degradation
- 85% to 90% SoH | Good – normal, expected battery wear
- 80% to 85% SoH | Fair – degradation has started, maximum driving range slightly shorter
- 75% to 80% SoH | Moderate – reduction in driving range is noticeable
- 70% to 75% SoH | Poor – battery has experienced a significant capacity drop
State of Health should always be considered alongside vehicle age, mileage and intended use.
The Importance of Specialist Assessment
For higher-value purchases, professional assessment and specialist advice can provide valuable additional assurance.
At Copart, our Virtual Vehicle Viewing service gives buyers the chance to inspect a vehicle’s interior and exterior live via a pre-booked WhatsApp video call, helping them make an informed bidding decision.
It enables buyers to see specific areas of damage or concern – ideal for providing extra peace of mind before bidding on an EV.
Knowledge Creates Opportunity
At Copart, we continue to invest in the expertise, training and battery assessment capabilities needed to support the growing EV market.
By combining battery health data, thorough vehicle assessment, and transparent information and images on our Lot pages, buyers can purchase EVs with greater confidence.
For buyers who can look beyond the assumptions and myths around electric vehicles and focus on the available information, the expanding EV marketplace places huge opportunities at their fingertips!
