How the In Wheel Motor System for the Mitsubishi MiEV All Electric Car Works

Mitsubishi MiEV All Electric Car

Mitsubishi MiEV All Electric Car – ( Solar Thermal Magazine ). The Mitsubishi MiEV Electric Car Wheel Motor Concept. The Mitsubishi i-MiEV is a fully electric car. The internal combustion gasoline engine has been entirely replaced with a clean, efficient Mitsubishi electric motor and a high-tech drivetrain that produce zero on-road emissions.

MIEV motors are constructed using an in-wheel motor rotor, an in-wheel motor stator, a rotor bracket, stator bracket and inverter directly behind the brakes. The batteries can be charged from a standard 15 A/200 V car charger in seven hours and with a three-phase electric power charged in 25 minutes (for up to 80 percent of full capacity).The batteries are located under the floorpan and in the Colt uses 22 Li-ion modules to produce a cumulative 325 V. The design allows for an entirely electric vehicle, or a hybrid using the batteries to supplement a traditional internal combustion engine or a hydrogen fuel cell.

According to Mitsubishi, locating the motor behind the wheel offers the company three distinct advantages:

  1. It allows for a four wheel drive system without need of transmission, drive shafts, differential gears or other complex mechanical components. Mitsubishi Motors has been one of the few companies to persist in offering 4WD on vehicles other than off-road vehicles since the technology’s heyday in the 1980s.
  2. Placing the drive system entirely in the wheels allows for greater freedom of design for interior stylists.
  3. The space created facilitates the storage of the batteries, allowing for extra modules to be fitted which would offer increased power and range compared to previous electric vehicles.

Main stand out features include:

  • 100% Electric, No Gas required, Zero Tailpipe Emission Vehicle
  • On-board battery charging system with Level 1 120V, Level 2 240V, and Level 3 DC quick charge port
  • 120V portable 8 /12 amp switchable charging cable
  • Regenerative braking system

Only about 15% of the energy from the fuel you put in your tank gets used to move your car down the road or run useful accessories, such as air conditioning. The rest of the energy is lost to engine and drive line inefficiencies and idling. Therefore, the potential to improve fuel efficiency with advanced technologies is enormous.

With an Electric Car it costs just $2.00 per 100kms with MUCH more performance than with petrol at $20.00 per 100kms.

    I’m confused by this article, none of it makes any sense. The in-wheel electric motor is only a concept and not a reality at this point for cars. The current i-MiEV has a standard electric motor mounted between the rearwheels using a ‘transmission’ of sorts that connects the driveshafts to the wheels. The video included in this article is from 2006! All I can say is CrapTastic reporting by a staff writer.
