The environmental regulations to reduceaverage CO2 emissions and automotivetrends play in favor of stronger vehicleelectrification and faster deployment ofElectric Vehicles/ Hybrid Electric Vehicles(EV/HEVs). Yole Développement expectsthat EV/HEV market in number of vehicleswill reach 24 Million units by 2024.
Increasing battery energy capacity enableslonger driving range of electric cars andpowerful electric motors enable strongacceleration.
High electric power and needs for inverterdownsizing bring challenges on the powermodule level.
Innovations at this level concern differentsolution such as power module aspect(power card-like power module),baseplate structure (pin fin), coolingtechnology (double-side cooling).
Hitachi combines all these key innovationsin its new integrated 3rd generationdouble-side cooling power module. In thisdesign, Hitachi implements a built-insilicon insulated-gate bipolar transistors(IGBTs) and diodes.
System Plus Consulting presents a deepanalysis of the Hitachi power moduleintegrated in Audi e-tron’s inverter.
Supported by a full teardown of themodule’s components and housing, thisreport reveals Hitachi’s innovative assetsto assemble its 3rd generation double-sided cooling package as well as thedesigns of its IGBT and diode.
This report includes an estimatedmanufacturing cost of all the module’scomponents and its selling price analysis.It proposes a comparison between doublesided cooling automotive power modulesfrom Hitachi, Toyota, and Infineon.
These comparisons highlight differences inthe packaging design, dies, and costs.
