Disassembly work of the new Fit Hybrid system

The 4th generation new Fit hybrid model released by Honda in February 2020 adopts a 2-motor hybrid system named “e:HEV”, which is driven by the motor for most daily usage scenarios.

To mount a two-motor hybrid system on a compact car, the new Honda Fit features newly developed components such as a new power device, an RC-IGBT (reverse conducting-insulated-gate bipolar transistor) for the power control unit (PCU), flat magnet wires with void-imbued polyimide insulation coating for the motor windings, as well as a more compact cooling system and layout.

This report covers the disassembly work (conducted September 16 and 17 at the Saitama Institute of Automotive Technology) and the teardown components exhibition (held on October 1 and 2 at the Saitama Industrial Technology Center) which were organized by the Next Generation Vehicle Support Center of the Saitama Industrial Promotion Corporation. This report explains the electric components of Honda’s “e:HEV” two-motor hybrid system.

At the time of this event coverage, detailed areas of components such as the motor rotor, the PCU power module peripheral components, and the battery module had not been disassembled.
