Roadmap
- Step 1Lesson
High-voltage safety & isolation procedure
400–800V DC can be fatal; correctly rated insulated gloves checked before use, barriers and signage; remove the service plug, wait for capacitors to discharge, verify zero voltage.

- Step 3Skill
HV batteries, BMS & insulation testing
LFP and NMC cells, modules, BMS and balancing; measure insulation resistance with a megohmmeter; read SOC and SOH data; spot flood or crash damaged packs and quarantine them.
Requires: BEV, HEV and PHEV architecture

- Step 4Skill
Electric motors, inverters & reduction gears
Permanent magnet and induction motors, resolvers, IGBT and SiC inverters; check reduction gear leaks and noise; follow manufacturer removal and refit procedures.
Requires: HV batteries, BMS & insulation testing

- Step 5Skill
AC and DC charging, wallboxes & stations
Type 2 and CCS2 standards; install wallboxes with dedicated breaker and RCD; troubleshoot no-charge and slow charging; coordinate with electricians when upgrading supply capacity.
Requires: HV batteries, BMS & insulation testing
- Step 6Skill
12V system, thermal management & software diagnostics
A flat 12V battery stops the car even with a full HV pack; heat pumps and battery cooling loops; use factory diagnostic software, OTA updates, read insulation and charging faults.
Requires: Electric motors, inverters & reduction gears, AC and DC charging, wallboxes & stations
