OBC

MIRAE-OBC(EV) 6.6-I (On Board Charger)

OBC is composed of a stop value, a DC output device, a constant voltage reference device, etc. and is used to charge the battery pack of an electric vehicle
It is a high-voltage battery pack charger that is mounted on a vehicle with a fully automatic charging rectifier.

• Control performance

  Power factor control to meet input and power supply AC power standards

  DC link voltage and current control

• Protection function

  Output limit when the maximum capacity of OBC is exceeded

  Output limit when exceeding OBC limit temperature

  Limits the output when the battery pack is in contact with BMS

• CAN Interface(Protocol)

  High speed vehicle CAN2.0B (500kbps)

• Cooperative control

  Output voltage current limit according to BMS and charging

  If necessary, coordinate control with other system controllers

  BMS and charging start/stop sequence

  Charging stand interlocking control

• Protection Functions

  Over Voltage Fault

  Over Voltage Warning, Derating

  Over Current Fault

  Over Temperature Fault

  Over Temperature Warning, Derating

  Battery Pack Assy Protection: Output is restricted when the battery pack malfunctions in conjunction with BMS
