Mitsubishi i-MiEV
Mitsubishi i- MiEV
The Mitsubishi i- MiEV (三菱· i Mitsubishi i- MiEV, which MiEV Mitsubishi innovative Electric Vehicle stands ) is an electric microcar (K- Car) of the Japanese car manufacturer Mitsubishi Motors, introduced in 2006, based on the Mitsubishi i. With identical technology, the sister models, Citroën C -ZERO and Peugeot iOn will be offered. In Germany the electric micro-car has been available since March 2014 under the model name of Mitsubishi Electric Vehicle.
Manufacture and model refinement
On 5 June 2009 the serial production of this vehicle began in Japan. In August and September 2009, a tour of Germany with three right-hand drive vehicles took place in the context of which the electric vehicles were introduced in some parts of the public, journalists and businesses.
At the Geneva Motor Show in 2009 were presented next to the "i- MiEV SPORT AIR" "i -MiEV Prototype ". This is a specially designed for European claims concept car. Since December 2010, the Mitsubishi i- MiEV is available on the European market. In Germany, the i- MiEV was initially offered at a price of 34,990 euros plus transportation costs. Sold in its first month of December 2010, there were 11 new registrations in Germany. By June 2011 519 i- MiEV has been approved. To October 2012, according to a statement from Mitsubishi on the stand at the eCarTec 2012 in Munich were sold around 34,000 vehicles worldwide.
As of the 2012 model year, a facelift is performed, the standard equipment includes heated front seats, an integrated Radio-CD/MP3-Kombination, a switchable audible alarm up to a speed of 35 km / h and a remote control to control the air conditioning and charging the battery together with charge status display. The price has been reduced to 29,900 or 29,300 euros ( Austria / Germany ).
In August 2012, production of the C -ZERO and the iOn due to low sales figures was temporarily stopped.
For model year 2014 Mitsubishi announced a facelift of the Electric Vehicle, which was, inter alia, the maximum range increased from 150 to 160 kilometers in the frame and LED instead of halogen headlights to be used. Furthermore, the starting price by over 10,000 euros to 23,790 euros has been lowered. The electric vehicle will be available in Germany from April 2014.

Technology
Motor
The sole drive of the i -MiEV is a permanent magnet synchronous motor with an output of 49 kW (67 hp) and a torque of 180 Nm. The electric motor is disposed under the luggage compartment and drives the rear axles. An originally announced hub motor was again discarded. The acceleration from 0 to 100 km / h takes about 15.9 s
Traction battery
The in the floor of the vehicle housed 200 kilograms traction battery consists of 88 lithium - ion battery cells on the cathode LiMn2O4 technology. The cells with 50 amp hours and a nominal cell voltage of 3.7 volts each lead to a total voltage of about 330 volts. The cell blocks labeled LEV50 -4 made by the supplier GS Yuasa and are equipped with 109 Wh / kg and given 218 Wh / l. The traction battery can be fully charged via a standard 230 V outlet in approximately 6 hours. In addition, there is the possibility of the accumulator by means of a specific fast-charging station under Japanese CHAdeMO standard DC power supply with up to 62.5 kW in 15 to 30 minutes to charge to 80%. The energy content (stored labor ) of the Li battery is 16 kWh (nominal capacity). For the sake of life is limited to 70 to 80 % of Nennkapaztität (11-13 kWh) by the battery management system (BMS ) use. The traction battery cost in the year 2009 14.000 $, with later mass production are sought 800 to $ 1200.
The Citroën C- ZERO sister models and Peugeot iOn in 2012 the battery was reduced by 8 cells. In parallel, the available capacity fell to 14.5 kWh.
From the technical details, several important conclusions can be derived:
- The battery can only work in the range between 12 ° C and 31 ° C at 100%.
- Temperatures > 31 ° C lead to performance degradation and > 50 ° C to destroy the battery cells.
- Temperatures <12 ° C lead to performance limitations, but only slightly. The shelf life is not impaired.
- The charging behavior (curve in the upper half ) is more limited by low temperatures than the discharge behavior (curve in the lower half ).
To ensure the best possible working temperatures and to optimize the life, Mitsubishi has an air cooling system that will, if necessary, activated by the battery management system. On a battery heating was omitted.
Technical details
The Mitsubishi i- MiEV has only traction battery through a lead-acid battery with 12 volt / 27 Ah for the control units, lighting, power steering, vacuum and water pump, audio system. This is recharged by a DC / DC converter from the traction battery. The traction battery supplies power directly to the electric motor, air conditioning compressor and vehicle heating with 5 kW rated power. The combination of the components takes place via CAN bus, monitoring via battery management system.
Construction
Another unusual feature for a modern small car is that the Mitsubishi i -MiEV has a self-supporting aluminum body skeleton.
For the European market the track forward, widened by 95 rear 135 mm; the total width is thus 1475 mm. The overhangs front and rear of the occupant and pedestrian protection extended by 55 mm, resulting in a total length of 3475 mm.
Technical information
The i- MiEV has with the 16 kWh battery has a range of 150 kilometers in the New European Driving Cycle (NEDC). The top speed is 130 km / h According to CoC - sheet of the i- MiEV has an energy consumption of 135 Wh / km, ie 13.5 kWh per 100 km from outlet (tank -to-wheel ).
In an ADAC test on a given route in South Tyrol, the tested Peugeot iOn consumed 12.87 kWh per 100 km. This corresponds to a consumption of 1.45 liters of petrol.
Optimized range
The traction battery can develop their full potential only in warm weather. Only then up to 160 km range are possible. If the battery temperature during charging to 0 ° C, the battery can only be charged to about 60%. The segment display does not answer this, but the exact range indicator. If the battery is colder than -20 ° C, they can no longer load. Conversely, a fully charged battery in warm temperatures at -10 ° C is almost 100% efficient, at -20 ° C nor more than 60%. The operation of the fully electric heating to the highest level with 5 kW is roughly equivalent to the energy consumption for a constant speed of 50 km / h The range is reduced accordingly.
Awards
In 2011, the Mitsubishi i- MiEV was awarded the Plus X Award for Best electric vehicle. Furthermore, the first electric car in series production in 2012, for the second time already, was honored by the automobile federation FIA Alternative drive systems in the class as the winner.
