MUTE [Mju: t] (also written mu + e) is an electric car based on a concept for a fully electric, two-seater lightweight compact car with a range of at least 100 km. The vehicle, which is being researched and developed as part of the MUTE project at the Technical University of Munich , is designed for urban and regional use. The final design was presented to the public for the first time as a show car at the 2011 IAA .
Project description
The MUTE project of the Technical University of Munich includes the development of an economical and safe electric vehicle without restricting individual mobility. Use is planned for urban and suburban living spaces as well as for rural areas with regional use. The original idea and initiative goes back to the Chair for Vehicle Technology at the Technical University of Munich. The team now consists of more than 200 assistants and students from more than 20 participating chairs from various disciplines at the Technical University of Munich. In addition, several industrial partners are involved in the project.
design
The design of the MUTE is geared towards the best possible aerodynamics , with ergonomic requirements, the coordination of the assemblies and legal requirements being taken into account. The vehicle design is similar to a coupé and is determined by sporty elements such as short overhangs, horizontal lines in the front and rear and flared wheel arches.
Technical specifications
| Admission | L7E |
| people | 2 |
| Payload | 2 pieces of luggage (510 liters of storage space) |
| Vehicle length | 3.55 m |
| drive | Central machine, rear wheel drive with active torque vectoring gear |
| Weight | 500 kg (including 100 kg battery) |
| battery | Li-ion battery (capacity 10 kWh) + zinc-air battery |
| Top speed | 120 km / h |
| Acceleration 0–60 km / h | 6.8 s |
| Range | > 100 km |
Chassis and drive
The chassis has front and rear wheel suspensions with MacPherson struts . The car is powered by a central electric motor. A torque vectoring transmission allows the drive torque to be dynamically distributed between the driven wheels, thus enabling good driving dynamics and traction.
Energy storage
The vehicle concept provides for a combination of a lithium-ion main battery with an electrochemical range extender based on a zinc-air battery . The lithium-ion battery with a capacity of 10 kWh is located in the impact-protected interior of the vehicle. Due to the low weight, a comparatively small main battery is sufficient. The zinc-air battery is installed in the front of the vehicle. The "Range Extender" is used to extend the daily available range. After use, it has to be replaced and can be processed industrially. Daily operation takes place on the main battery, while the range extender avoids getting stuck.
electronics
Selected high-voltage cables for the on-board network are made of aluminum to save weight. Due to the high voltage, the less good conductivity compared to copper is not significant. The contacts of the aluminum lines require specially shaped plug connections.
Heating concept
The interior of the e-car can be tempered on cool days using a bioethanol-powered heater. The power of the unit integrated in the air distribution system is 2 kW. An intelligent control system that evaluates several humidity and temperature sensors creates a comfortable climate with minimal energy consumption and prevents windows from fogging up.
safety
The approval class L7E , in which MUTE is classified, contains only very few safety regulations and no regulations regarding crash tests. Since the MUTE gives the impression of a conventional car due to its design and the achievable driving performance, the customers' high expectations of vehicle safety should be met. This is achieved through relatively long crash paths in conjunction with crash side members made of fiber composite material . These absorb the impact energy homogeneously over the available path without load peaks. The aim is to achieve a level of safety that is based on that of conventional vehicles.
ergonomics
The interior was designed using the RAMSIS digital human model . The implementation of the so-called “Augpunkt-Fix-Concept” enables occupants of different proportions to sit comfortably and to have the best possible view. With this concept, the driver's eyes are always in the same place, i.e. the seat can only be adjusted in height, but not lengthways. In addition, the pedals, the steering wheel and the central control element can be adjusted. This principle enables the airbag to be optimally designed in the head position of the occupants, which reduces the risk of injury in the event of a collision.
Services and infrastructure
The central control element is a centrally arranged touchscreen , via which the driver can operate all functions not directly linked to the driving task and also has access to supporting services such as fuel-efficient driving or the display of nearby charging stations.
costs
The acquisition and maintenance costs ( total cost of ownership ) are based on those of a comparable small car with a conventional drive. In addition, Car-Sharing offers, similar to the Car2go model running by Smart in Ulm , are being worked on.
