back to topDescription

This optional High Voltage front end, when combined with a BMS controller, completes a Li-Ion BMS by adding safety testing and may include current sensing.

Note that some BMS controllers already include a High Voltage front end within their enclosures.
However, a separate HV front end:

  • Keeps the high voltage away from the BMS controller
  • Keeps any electrical noise away from the BMS controller
  • May simplify the layout of high voltage cabling

This separate High Voltage front end performs these functions:

  • Tests for end of precharge through a precharge resistor
  • Tests for loss of insulation
  • Measures battery current (except the 2HV0000B)

This HV front end includes:

  • An on-board current sensor (except the 2HV0000B)

This HV front end does not include:
