Simulating the HV batterie using an adjustable power supply. Have an IVT shunt connected [Can2], reading the incoming high voltage.
case A:
- UDC parameter is set to 58V.
- power supply is set to 56V
enabling T15 and pushing start, I see the PRECHARGE relay being activated. Now i turn the PS knob slowly to 60V.
At around 58V, I see the MAIN relay coming on.
Suprised to see the PreCharge relay staying on, it never turn off.
Shouldn't it go off once UDC is reached?
case B:
- UDC parameter is set to 58V.
- power supply is set to 59V
enabling T15 and pressing start, I see the MAIN relay being activated immediately. It seems that PRECHARGE never turns on, which makes sense, since
the defined 58V is already is achieved.
Is case (A) a bug? Should the PRECHARGE relay turn off?
Might this be the reason why Damien blew a contactor is his Mitsubishi L200 build?
