| Abstract: | The monitoring of the key parameters in the high-voltage system,responsible for the safe operation of the electric vehicle,including those characterizing the insulation condition of the system,the connection of the power circuit,the performance of the high-voltage contacts,were discussed.The mathematical models for the monitoring method were explored theoretically and introduced to measure these parameters.They were also verified experimentally.Using these models an electronic unit,namely the diagnostic and high-voltage safety management unit was developed and its on-line judgement strategy was proposed. |
| Keywords: | vehicle engineering electric vehicle insulation condition power circuit high-voltage contact |
