Ground capacitance measurment for Isolation monitoring device

I am designing an Insulation Monitoring Device for an electric vehicle. The battery voltage of the EV can go up to 1000V. I want to measure the ground capacitance of the electric vehicle to mitigate its effect in isolation monitoring. What method should I use to do this on the IMD PCB? Will AC ...

AD5270 digital potentiometer (SPI interface,16 BIT)

Has anyone worked with AD5270 digital potentiometer? When im trying to change the resistor value of the potentiometer using cube ide by sending the 16 bit control command and 16 bit resistor value command it wont change.Resistor value is frozen always it doesnt change its value.Can anyone help me ...

Re: Tesla precharge feedback

i want to know is how the bms knows capacitors are charged near to the battery voltage level?what is the method used to identify the charge level of capacitors in the inverter?Im new to this field sorry if I said something wrong.

Tesla precharge feedback

Does anyone has the information about how the pre charge feedback of a tesla is obtained? what are the components or logic that is used to achieve that? how the voltage in the motor controller side is measured in order to open the precharge relay and close the main contacts
