Component level battery diagnostics

Remove uncertainty through precise battery diagnostics and structured reporting.

Full fault visibility fuelled by comprehensive diagnostics

Our battery diagnostics identify faults at the component level. This gives a clear view of battery degradation, performance issues and safety-critical faults before any work begins.

Accurate diagnostics ensure we identify the specific repair needed, only complete necessary repairs, and resolve issues faster – all of which ensures we keep costs lower and improve sustainability.

Comprehensive assessment to expose root cause

Our expert teams follow structured processes to understand exactly what caused an issue and provide detailed reports of our findings. This understanding helps reduce warranty costs through preventative maintenance, improve product quality and enables targeted rather than mass recalls.

Our diagnostic process

01 Connect and capture data

Connect to the battery system to collect live and historical data, including voltage, temperature, state of charge, fault
codes and operational history.

02 Assess battery health

Analyse battery performance indicators to establish overall condition, identify degradation patterns, and determine whether issues are isolated or systemic.

03 Detect & isolate faults

Pinpoint the source of the faults, distinguishing between battery related issues and vehicle system interactions

Key areas of diagnostic investigation

State of charge

Understanding how energy is distributed throughout the battery pack, helping identify cell imbalance, charging anomalies and underlying performance issues before they result in failure.

BMS data interrogation

Reviewing battery management system data, fault histories and operational trends to reveal what the battery has experienced throughout its service life and uncover potential root causes that may not be visible through physical inspection alone.

Capacity & EV battery health check

Quantifying available energy capacity and overall battery health to provide a clear assessment of degradation, remaining service life and the most appropriate next steps.

Resistance

Evaluating electrical resistance at cell, module and pack level to identify deterioration, connection issues and emerging faults that may impact performance or safety.

Isolation

Confirming the high-voltage system remains electrically secure by detecting insulation breakdown or leakage paths that could compromise battery safety and reliability.

Better decisions based on evidence

Our battery diagnostics provide a comprehensive picture of each battery’s health, condition and future requirements. We identify the exact issue so we can establish the best strategy for that battery. EV battery testing with root cause analysis reduces unnecessary work, improves reliability and lowers long-term costs.

What happens after our diagnostics checks?

We’ll recommend next steps based on your standards, repair options and commercial reality. We only repair batteries where strict standards can be met.

Where possible, we would replace or repair the faulty components within the battery before recertifying them to manufacturer standards.

Visibility at every stage

Our specialist technicians record all diagnostic data on our platform, ALFRED, giving you total oversight at all times. It provides a clear, tracked record of your battery’s history and adds it all to your battery passport.

Offering unrivalled transparency, ALFRED provides live updates, tailored dashboards and clear trends to help you understand performance, spot issues and make faster, better-informed decisions.
