EV Battery Diagnostics – What Can THINKCAR Actually Tell You?

EV Battery Diagnostics – What Can THINKCAR Actually Tell You?As more electric vehicles enter UK workshops, diagnostics is starting to go beyond simply reading and clearing fault codes.
One of the biggest questions with any used or ageing EV is the condition of its most expensive component:

The high-voltage battery.
So what can THINKCAR actually tell you about it?
EV Diagnostics Are Already Part of THINKCAR It's worth clearing up one thing first.
You don't need a dedicated EV tool just to diagnose an electric vehicle with THINKCAR.
Our professional diagnostic platforms already provide EV diagnostic and service capability, allowing technicians to communicate with systems across vehicles such as Tesla, Volkswagen ID models, Nissan Leaf and many others.

For workshops wanting to go further, THINKCAR's dedicated EV diagnostic capability allows much deeper analysis of the high-voltage battery itself.

What Is EV Battery State of Health (SOH)?State of Health — usually shown as SOH — is an indication of the condition of an EV battery compared with when it was new.

That's becoming increasingly useful information for workshops.
A vehicle might drive normally and have no obvious battery warning, but that doesn't necessarily tell you how the battery has aged or whether individual cells are behaving as expected.
With THINKCAR's EV battery diagnostic capability, technicians can access information including:

• Battery State of Health (SOH)
• Individual cell voltages
• Cell voltage differences
• Battery temperatures
• Charging and discharging information
• High-voltage battery data

Rather than guessing at battery condition, you've got actual vehicle data to work with.

​This demonstration shows how THINKCAR can access EV battery information and give the technician a clearer picture of what's happening inside the battery pack.
What Does This Look Like on a Tesla?Here's a real example from a Tesla tested using THINKCAR diagnostics.

The important part isn't simply producing another diagnostic report.
It's being able to give the technician useful information about the vehicle and its high-voltage systems that can be saved, reviewed and used as part of the diagnostic process.
For workshops working with used EVs, battery faults or customers concerned about battery condition, this type of information is only going to become more relevant.

Going Deeper With the THINKCAR EV PackFor workshops specialising in EV work, the THINKCAR EV Pack takes diagnostics beyond normal vehicle communication.

It provides access to individual battery cell information and detailed battery data, with the ability to test supported battery packs outside the vehicle.

The EV Pack is included with professional platforms including the Thinkcar 394 and Thinkcar 399, and is available as an upgrade for selected other THINKCAR professional diagnostic platforms.
EV Diagnostics for UK WorkshopsEVs aren't something workshops can keep treating as a job for the future.

They're already coming through the doors.
The question is whether your diagnostic equipment gives you enough information to confidently work on them.

From everyday EV fault finding through to high-voltage battery diagnostics, State of Health testing and individual cell analysis, THINKCAR gives independent UK workshops the ability to take EV diagnostics further.
And as always, official Thinkcar UK equipment is backed by our UK technical support and authorised dealer network.
