2HR0xxxB series HV Front Ends
Lithiumate™ remote High Voltage Front End, board level
Board level, remote HV Front End
This optional, Remote High Voltage Front End, may be used with a BMS controller, to add certain testing before turning on contactors:
- Absence of current leakage between battery and chassis
- Presence of battery voltage
- Contactors are operational
- End of precharge inrush current pulse
May include battery current sensors:
- None, ±5 or ±20 A for the source current
- None, ±50, ±100 or ±200 A for the load current
Includes drivers for contactors, including a precharge relay.
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 Remote HV Front End communicates with the BMS controller through the CAN bus (as opposed to the 2HV0xxxB, which does so through a short, 8-wire cable).
