As electric vehicles become increasingly common on UK roads, understanding the condition of your vehicle’s battery has never been more important. At SI Auto Ampthill, we’re proud to introduce our latest specialist service – the EV High Voltage (HV) Battery Health Check (State of Health – SOH).
If you own an electric vehicle in Ampthill, Bedford, Flitwick or anywhere across Bedfordshire, this advanced diagnostic service provides valuable insight into the condition and performance of your EV’s most important component – the high-voltage battery.
What Is an EV Battery Health Check?
The high-voltage battery is the heart of every electric vehicle. Over time, all batteries naturally lose some of their original capacity through normal charging and usage.
Our State of Health (SOH) Battery Check measures the overall condition of your battery, giving you a clear picture of how it compares to when it was new.
Rather than guessing how your battery is performing, you’ll receive accurate data that can help you make informed decisions about maintenance, ownership and future resale.
What Does “State of Health (SOH)” Mean?
State of Health (SOH) is a percentage that indicates how much of your battery’s original capacity remains.
For example:
- 100% SOH – The battery is performing like new.
- 95% SOH – Excellent condition with very little degradation.
- 90% SOH – Normal wear for many electric vehicles.
- 80% SOH or below – The battery has experienced more significant degradation and may require closer monitoring.
Knowing your SOH helps you understand the long-term performance of your EV and can identify potential issues before they become costly.
Why Is a Battery Health Check Important?
Your EV’s battery is the most valuable component of the vehicle, often accounting for a significant proportion of its overall value.
Regular battery health checks can help you:
- Understand your battery’s remaining capacity.
- Monitor battery degradation over time.
- Identify potential faults early.
- Plan for future ownership costs.
- Improve confidence before long journeys.
- Support warranty or insurance discussions.
- Increase buyer confidence if you’re selling your vehicle.
For many EV owners, a battery health report offers peace of mind that their vehicle is performing exactly as it should.
Buying or Selling an Electric Vehicle?
One of the best times to have an EV Battery Health Check carried out is before buying or selling an electric vehicle.
Buying an EV
A vehicle may look immaculate on the outside, but the condition of the battery tells the real story.
An SOH report can help you:
- Avoid unexpected repair costs.
- Confirm the battery is performing as expected.
- Negotiate confidently with sellers.
- Understand the vehicle’s true value.
Selling an EV
Providing an independent battery health report demonstrates transparency and reassures potential buyers.
It can help your vehicle stand out from others on the market and give buyers confidence in their purchase.
