Ford Escape: Voltage Converter/Inverter / Description and Operation - Direct Current/Direct Current (DC/DC) Converter Control Module - Overview

OVERVIEW

  WARNING: To prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to depower the system. The high-voltage hybrid system utilizes approximately 300 volts DC, provided through high-voltage cables to its components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage components are marked with high-voltage warning labels with a high-voltage symbol. Failure to follow these instructions may result in serious personal injury or death.

The DCDC is a liquid cooled component that converts high-voltage DC power from the high voltage battery to low-voltage (12 volts) DC power. The DCDC charges the 12-volt battery through the low-voltage battery cables and powers the low-voltage electrical system, this eliminates the need for a conventional engine-driven alternator. The DCDC communicates with other modules over the HS-CAN1 . The DCDC is serviceable and located in the engine compartment on the LH shock tower.
