Headline: Great news for local EV owners / used EV buyers in Ampthill! 🙌⚡

Just wanted to give a quick shout-out and share a brilliant new service being offered locally.

Igors over at SI Auto Ampthill (the independent garage down at L W Vass) is now doing official High Voltage EV Battery State of Health (SoH) testing.

If you’ve ever looked into buying a used electric car, you know the absolute biggest worry is whether the battery is secretly degraded. The dashboard "estimated range" can be easily fooled, but an SoH test plugs right into the car's diagnostic system to give you the actual remaining battery capacity as an exact percentage.

This is massive if you are:

Looking to buy a used EV privately or from a dealer and want an independent check first.

Selling your EV and want proof for the buyer that your battery is pristine to protect your resale value.

Approaching the end of your manufacturer's 8-year battery warranty and want to check if you qualify for a replacement before it expires.

It’s fantastic to see a local independent garage investing in proper EV diagnostic kit so we don't have to traipse to expensive main dealers in Milton Keynes or Bedford.

Give Igor a shout at SI Auto if your EV needs a health check! 🔌🚗

Professional EV Battery Health Testing at SI Auto Ampthill
At SI Auto Ampthill, we provide professional, data-driven High Voltage (HV) Battery State of Health (SOH) testing to give EV owners and buyers total transparency.

While a dashboard might show a "100% charge," that only tells you the battery is full—not how much its total capacity has degraded over time. Our specialist diagnostic tools extract the raw data directly from the Battery Management System (BMS) to provide a certified health report.

Si auto Ampthill Offering EVs HV battery SOH check

Whether you are a private EV owner, looking to sell your car, or considering a used purchase, having a definitive State of Health (SOH) report for your High Voltage (HV) battery is essential for peace of mind and resale value.

1. Comprehensive SOH Diagnostic
We plug directly into your vehicle’s Management System to extract real-time data from the Battery Management System (BMS).

Capacity Verification: Accurate percentage of the battery's remaining capacity compared to when it was new.

Cell Voltage Analysis: Checking for imbalances between individual cells that could indicate future failure.

Thermal Monitoring: Assessing the health of the battery cooling and heating systems.

2. EV & Hybrid Inspection

3. Resale & Purchase Peace of Mind
For Sellers: A professional SOH certificate proves your battery has been well-maintained, justifying a higher asking price.

For Buyers: Don’t rely on the "estimated range" on the dash, which fluctuates based on driving style. Get a raw data report before you buy.

Note: We recommend a full HV battery health check annually or prior to the expiration of your manufacturer’s battery warranty (typically 8 years/100,000 miles).
