Electric Drive Units (EDUs)
The Hyundai Ioniq 5, while also available in Rear-Wheel Drive (RWD), features a top-spec variant driven by two Electric Drive Units (EDUs). These EDUs provide an overall system power of 225 kW.
Each EDU incorporates the following key components:
- Oil-cooled electric motor
- Inverter utilizing SiC MOSFET technology
- 1-speed reducer gearbox
The Front EDU is equipped with a clutch, allowing it to disengage the unit for specific operation modes. The Rear EDU handles DC charging functionality, facilitating voltage conversion from 400V to 800V.
Visual Description: The Electric Drive Units are shown as complex mechanical assemblies. The Front EDU is depicted above the Rear EDU. Labels identify the Inverter, Electric motor, Gearbox, and Oil pump within the Front EDU.
HV Battery
The Hyundai Ioniq 5 is offered with various battery variants, ranging from 58 kWh up to 77.4 kWh in the MY2023 version. Built on the E-GMP platform, the battery operates at an 800V voltage level, which influences the configuration of its modules and HV connections.
The battery housing is constructed from:
- Main housing made of welded aluminum profiles
- Sheet metal cover
- Polymer underride guard
A cooling plate is integrated directly into the main housing for thermal management.
Visual Description: The High Voltage (HV) Battery is presented as a large, rectangular unit containing multiple battery cells. Key connection points and structural elements are labeled, including the Battery disconnect unit, HV connector, Module, and Main housing.
Power Electronics
Beyond the traction inverters, the Ioniq 5 powertrain includes several other power electronic components:
- An 11 kW bidirectional On-board Charger.
- A switch box designed to distribute energy to the rear EDU.
- A power delivery unit responsible for distributing energy to the front EDU.
- The Integrated Charging Control Unit (ICCU), supplied by Hyundai Mobis. The ICCU manages 11 kW AC charging functionality and includes a 12 V DC/DC converter.
The Ioniq 5 also features a "Vehicle-to-Load" option, providing a 220 V socket at the back seat, powered by the On-board Charger.
Visual Description: Various power electronic modules are displayed, including the Integrated Charging Control Unit (ICCU), a Power delivery unit, and a Switch box, all showing intricate electronic circuitry and connectors.
