Testing

The testing of batteries will cover everything from a single cell through to complete battery pack.

Prior to having an actual cell the chemistry will be tested as a half cell against a reference electrode. These tests give directional data for the electrochemists developing the next generation of chemistry.

The battery cells will then mature from A-sample through to D-sample. At each stage these cells will be performance tested, undergo ageing cycle testing, parameterization for modelling and stages of legislative testing.

Chemistry Analysis

  • Power on / Power off logic
  • Electrical
  • Thermal
  • Mechanical
EV and Hybrid Qualifications

Level 1 is basic hazard awareness and gives you an understanding of why the industry is going EV, ideal for non tech people from valeters, managers, sales personnel etc.

Level 4 is where we do live HV work, opening up battery packs to test and repair them, as well as getting a deeper understanding of motors, inverters and other HV parts so you can diagnose and fix them. Aimed at Master Techs and those needing a deeper understanding of EV systems.

BMS Testing

  • Startup / Shutdown logic / Initialisation checks
  • HV system control
  • SoX algorithm performance
  • Fault injection
  • Handshake to system
  • Error codes and reporting

Pack Testing

  • Control System
  • Performance
  • Mechanical
  • Thermal
  • Electrical
  • Abuse Testing
  • Legislative Testing

System Design Sign-Off

The final sign-off will be at complete pack level and should be against test data, BMS control response, legislative test results and against the model of the pack.
