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.

HV Distribution
- 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.
