Used EVs in Pakistan - Battery State of Health (SoH) Checking Guide
{/* visual_plan: stat_block */}
Key Takeaways
- Checking Battery State of Health (SoH) is the most critical inspection step when buying a used electric vehicle in Pakistan.
- An OBD-II scanner reveals real-time battery cell voltage balance, total Quick Charge counts, and capacity degradation.
- Used Nissan Leafs with passive air-cooled batteries show faster degradation in hot Pakistani summer climates.
- Verify charging port compatibility (CCS2 vs GB/T vs CHAdeMO) before purchasing grey-import used EVs.
Introduction
Buying a used electric vehicle in Pakistan requires a different inspection methodology than checking traditional petrol cars. While engine compression tests and oil dipsticks are irrelevant, measuring Battery State of Health (SoH), individual cell voltage parity, and BMS diagnostic logs determines a used EV's true remaining value.
What is Battery State of Health (SoH) and why does it matter?
The high-voltage traction battery represents 40 percent to 50 percent of an electric car's total vehicle value. Over years of guiding and summer heat exposure, lithium battery cells experience gradual chemical capacity degradation.
Battery SoH Percentage | Battery Health Condition | Real-World Range Retention | Recommendation |
|---|---|---|---|
90% - 100% | Excellent Condition | 90% to 100% of original range | Highly Recommended |
80% - 89% | Good Condition | 80% to 89% of original range | Recommended at Fair Market Price |
70% - 79% | Moderate Degradation | 70% to 79% of original range | Negotiate Significant Discount |
Below 70% | High Degradation | Under 65% of original range | Avoid unless battery pack is replaced |
Inspecting SoH ensures you do not overpay for a degraded battery pack.
How to perform an OBD-II battery diagnostic check?
Step 1: Connect an OBD-II Bluetooth scanner to the diagnostic port located under the dashboard driver side.
Step 2: Pair the scanner with specialized EV diagnostic software (such as LeafSpy, Car Scanner ELM327, or MG OBD).
Step 3: Read Cell Voltage Variance. A healthy pack shows less than 15 mV difference between the highest and lowest voltage cells. A variance above 50 mV indicates bad battery cells.

Frequently Asked Questions
What is Battery State of Health (SoH) in a used electric car?
State of Health (SoH) is a percentage metric comparing a used EV battery's current energy storage capacity against its original factory capacity. An SoH above 85% indicates a healthy battery.
How can buyers test used EV battery health in Pakistan?
Use an OBD-II Bluetooth diagnostic scanner paired with specialized EV apps (like LeafSpy for Nissan Leaf or OBD Ampera for MG) to read real-time battery cell voltages and SoH.
What SoH percentage is considered acceptable when buying a used EV?
An SoH rating of 85% to 95% is acceptable for 3 to 5-year-old used electric cars. Avoid vehicles with SoH below 75% unless priced for battery replacement.
