DCDC System
The DCDC system accepts high voltage (HV) input
from the ESS and converts it to 24V low voltage (LV)
to charge the two LV batteries, which power the 12V
and 24V equipment throughout the vehicle.
Component Descriptions
DCDC
The DCDC converts 650V DC input supplied by the
ESS to 24V DC output. It consists of a power stage,
which performs the DC-DC conversion, and a control
stage. The control stage is powered by 24V DC
voltage and is connected to the CAN network. The
24V output from the DCDC is used to charge the two
low voltage batteries. The DCDC is connected to the
cooling circuit to help maintain the proper operating
temperature.
