Optimum packaging
Based on the i city car’s rear-midship design, the i-MiEV replaces the conventional engine, transmission and fuel tank with a lithium-ion battery system, motor, inverter and other EV components.
The long wheelbase, a feature of rear-midship layout, provides space for high capacity lithium-ion batteries under the floor. It also enables the motor and inverter to be installed in the space that used to house the conventional engine and transmission. i-MiEV ensures no compromise in cabin space for 4 adult passengers and good luggage space in the rear. What’s more, the rear seats fold completely flat, providing a large luggage area for moving larger items.
The installation of batteries under the floor also makes the i-MiEV’s centre of gravity low, which provides a very stable driving dynamic.
High capacity batteries
EV batteries must have high energy density, and the i-MiEV utilises high energy density lithium-ion batteries. A module consists of 4 cells, and 22 modules make one battery pack. Thanks to the structure of the modules, which allows them to be installed in either a vertical or transverse position, each high-capacity battery pack can fit under the floor. With these batteries installed, the range is 80 miles (target EU combined mode).
Highly efficient motor
The highly efficient electric motor can be built smaller than a petrol engine, while still producing high torque at low revolutions. The i-MiEV’s small, light weight, highly efficient permanent magnet synchronous motor provides sportier, quieter driving and power superior to the petrol i’s turbo charged 660cc engine.
Three ways to charge
Using the on-board charger, the vehicle can be charged with a standard UK 240V domestic power source in the home. All you need is a three pin plug socket and the car will charge itself from completely flat to 100% full in 6 hours.
In addition, when quick-chargers (currently being developed by power companies) are available, it will be possible to charge the vehicle from flat to 80% full in as little as 30 minutes.
Finally, the i-MiEV comes with regenerative braking, converting kinetic energy via the on board charger.
