If you’re considering an electric vehicle (EV), you’re in good company.

In addition to the large selection of cars, there is an increase in the number of heavy duty vehicles being added to the EV market.

This has significantly increased the number of people buying EV’s.

Buyers are driven by a desire for environmental friendliness, rising gas prices, and the increasing availability of EVs at more affordable prices, especially on the used market.

If this is your first time buying a used EV, you likely have some questions. Used EVs can be a smart investment, but they come with their own unique considerations.

This guide will walk you through everything you need to know to make an informed, confident decision that suits your driving needs, your home charging situation, and your lifestyle.

Unlike traditional gasoline-powered cars, EVs rely heavily on battery health, charging options, and software updates.

Additionally, you’ll want to equip yourself with essential accessories and tools to maximize your experience.

By understanding these factors, you can navigate the process with ease and ensure your used EV purchase is a success.

1. Start With Your Driving Habits

Before you even look at battery size or charging options, it’s important to think about how you will actually use your vehicle. This will help you determine the right EV for your lifestyle:

  • Daily commuting (10-40 miles/day): A small to medium-range EV (150–300 miles per charge) could be a perfect fit. Short commutes typically only require 100-150 miles per charge.
  • Delivery or gig work: Look for longer range, efficient battery use, and fast-charging capabilities.
  • Frequent road trips or longer drives: Prioritize battery capacity and compatibility with nationwide charging networks. For longer drives or towing, aim for vehicles with 250+ miles of range.
  • Mountain or rural driving: Regenerative braking helps in hilly areas, but make sure the EV performs well in cold or steep terrain. Keep in mind that driving in hills will affect how far you can drive on a charge.
  • Urban life with limited parking: Smaller EVs with decent range can be a great fit, just ensure you have access to reliable charging.

Pro Tip: Use apps like ChargePoint, PlugShare, Recargo, EVgo or A Better Route Planner (ABRP) to map out how an EV fits into your typical routes.

2. Understanding EV Battery Health

The battery is truly the heart of any electric vehicle, dictating its range and overall usability. Unlike a fuel tank, EV batteries degrade over time, slowly losing capacity.

Therefore, assessing the battery health of a used EV is absolutely crucial.

  • State of Health (SOH) reports: These reports tell you how well the battery is performing compared to when it was new. Most EVs offer a built-in diagnostic report showing the battery’s capacity compared to its original state.
  • Ask for the battery report: Request this from the seller or dealership. Many newer EVs have this feature built into their software.
  • Battery warranties: These often last 8 years or 100,000 miles. Always check if the warranty is still valid.
  • Consistent charging habits: Ask the seller how the car was usually charged. Frequent use of DC fast charging can accelerate battery degradation.
  • Use an OBD-II Scanner: This diagnostic tool can provide insights into battery performance and any hidden issues. A well-maintained battery can retain a significant portion of its original capacity even after years of use.

Recommended Product: The OBDLink MX+ Bluetooth OBD2 Scanner is a great tool, offering Bluetooth compatibility for iOS, Android, and Windows, and providing real-time battery health data for EVs with easy-to-use diagnostic reports.

3. How Much Range Do You Really Need?

It can be tempting to opt for the EV with the biggest battery and longest range. However, if you’re primarily driving 20-30 miles a day, that extra capacity might be more cost than it’s worth.

  • Short commutes: 100-150 miles per charge is often sufficient.
  • Longer drives or towing: Look for 250+ mile range vehicles.
  • Driving topography: Driving in hills will affect how far you can drive on a charge.
  • Battery size considerations: Battery size affects charge time, cost, and home charging infrastructure, so match it to your actual needs.

Quick Tip: Extreme cold or hot weather can reduce range by 20% or more. If you live in a place with winters or desert summers, plan for this buffer. EVs perform differently in very hot or cold climates, so pre-conditioning (warming up while plugged in) helps in cold weather, and parking in the shade can help in hot weather. Look for models with heat pumps for better winter efficiency.

4. Charging Compatibility (CCS vs. CHAdeMO vs. Tesla)

All chargers have two type of connectors. One end that plugs into the charging unit and the other end that plugs into cars.

Here we will discuss the end that plugs into the charger.

Not all EVs use the same type of sockets, which is an important consideration. Before purchasing a used EV, evaluate your access to charging stations and check the EV’s charging port type.

  • CCS (Combined Charging System): Most common on newer EVs (Ford, GM, Hyundai, VW, etc.). It works with Level 2 and DC fast charging.
  • CHAdeMO: Primarily found on older Nissan Leafs. Fewer fast-charging stations support this now.
  • Tesla/NACS: Proprietary plug used by Tesla, though other automakers are starting to adopt it.

If you’re buying a used EV, make sure:

  • It matches the charging infrastructure near you.
  • You have the right cable or adapter for home use.

Whenever you buy an EV, you want to make sure that it comes with at least a Level 1 charging cable.

Pro Tip: Look up what plugs are common in your area before choosing a model.

5. Home and Off-Grid Charging Options

Do you have access to home charging? It’s one of the biggest benefits of owning an EV. Charging at home is the most convenient option, ensuring your vehicle is always ready to go.

  • Level 1 (standard 110v wall outlet): Very slow (3-5 miles of range per hour). This is okay for short daily drivers or in a pinch.
  • Level 2 (240V outlet): Provides 20-30 miles of range per hour. Best for overnight charging. Installing a home Level 2 charger can significantly reduce charging time and improve overall convenience.
  • Solar + EV: If you have solar panels, you can charge your EV with the sun. This is perfect for off-grid or energy-conscious buyers.

Did You Know? You can use a smart charger that adjusts charging during off-peak hours to save money.

7. Inspect the Tires and Brakes

EVs generally require less maintenance than gas-powered cars. For instance, they don’t need oil changes or exhaust systems, and regenerative braking reduces brake wear. However, EVs are typically heavier due to battery weight, which means tires may wear out faster.

  • Tire Wear Patterns: Uneven wear could indicate alignment or suspension issues. Check the tread depth and overall condition of the tires.
  • Brake Pad Life: While regenerative braking extends brake life, a thorough check is still necessary.
  • Tire Pressure Monitoring System (TPMS): Ensure the TPMS is functioning correctly. Ensuring your tires are in good condition significantly affects your EV’s efficiency and safety.

Recommended Product: An AstroAI Digital Tire Pressure Gauge provides accurate readings, helps maintain optimal efficiency and range, and is small, lightweight, and easy to use.

8. Check the Vehicle History and Warranty

A used EV is only as good as its upkeep. Many EV manufacturers offer extended warranties on batteries and drivetrain components.

  • Maintenance records: Ask for maintenance records, battery replacements, and recall history. A comprehensive service history ensures the vehicle has been properly maintained and reduces the risk of unexpected repairs.
  • Manufacturer’s Warranty: Confirm how much time/mileage remains on the battery and drivetrain warranty. This can provide peace of mind.
  • Recalls: Verify if the vehicle has any outstanding recalls.
  • Included accessories: Make sure the charging port and cables are included in the sale.
