2HR0xxxE series HV Front Ends
Lithiumate™ remote High Voltage Front End, enclosed
Enclosed HV Front End. Click to enlarge.
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.
